With the launch of the new Gocycle G3 a big question on the horizon will be, what's the difference between the Gocycle G2 & G3? You should find this article helpful where the difference will be explained. Gocycle have not changed the format of the bike completely - Why? Because if something works, why change it? Therefore the same design characteristics of the frame geometry, angles, wheelbase, wheel size, posture & overall size remain the same, great news! What has changed are some of the vital components and the technology used within, this article outlines some of the main differences between the G2 and the G3. Visuals The first step will be how the Gocycle G3 looks vs the G2. They look very similar, however you'll notice their is a fancy new colour scheme available - Electric Blue. This colour looks amazing in the flesh and is a great addition to the current palette of Black, White or Grey. Lighting The new G3 has completely integrated lighting cables, whereas the G2 has internal cables that extrude the frame on each end. This gives a cleaner look and neater installation. It's worth noting here that although the lights are available as an optional extra on both Gocycle G2 & G3. They look similar but there are not backwards compatible between models. The new G3 lighting system has different bolts and mounts. Daytime Running Light The new Gocycle G3 has an integrated daytime running light for extra visibility over the G2. The standard dash on the G2 does not have this feature, nor can it be retrofitted. On the G3 it's completely integrated within the dash module. Dashboard The dashboard see's some revisions for the 3rd generation over the Gocycle G2. Firstly we see an edge-to-edge display for a sleeker look. We also see some addition to the dash LED's too. The addition of the 4 blue LED's represent the front daytime running light settings. Along with integrated rotary shifters, re-designed brake levers and comfort grips. Battery Range The Gocycle G2 has a 10.75Ah battery whereas Gocycle have managed to fit a larger 13.5Ah battery into the same space on the G3. This leads to up to 25% more range whilst keeping the weight to a tee. The range figures calculated (depending on rider input) on the Gocycle G2 offer up to 64km (40 miles) whereas the G3 now hosts up to 80km (50 miles). Whilst we are on the battery we also see a new BMS for faster charging over the G2 and also a moulded in charger connector, so the charger connection will feel more positive and should prevent the rubber seal on the G2 ejecting the charger plug. Comfort The grips on the G2 are standard round grips, whereas the G3 offers oval ergonomic grips for greater comfort. The saddle on both G2 & G3 has some small revisions but remains the same comfort. The pedals on the Gocycle G2 were rubber moulded whereas the G3 pedals have been widened & added some extra grip on top, they also benefit from new quality sealed bearings. PitStop Wheels The wheels on the Gocycle G2 and G3 remain a similar shape, the lightweight wheels actually feature a different locking mechanism on the G3, as like the G2 the cam levers remain, but the user has a secondary Hex Lock system to show that the wheels are positively engaged. Weight Weight is always important on any portable / folding bike, but even more so on a electric bike version. The fact that the Gocycle is portable is key to it's design, it's actually one of the lightest / smallest compacted electric bikes on the market at 16kg. Therefore it's important that the G3 doesn't way lots more than the G2 even with all the new features and bigger battery. We are surprised that Gocycle have managed to keep the weight the same across both generations, the G3 only adds 300 grams to the overall weight! Conclusion As you can see there have been many changes between the Gocycle generations. Of course there are many other changes from the G3 over the G2, certainly too many to delve into detail. But to name a few: New high quality bearings, improved fitting hub cap, concealed lighting cables, integrated seat tube collar, kickstand tab for easier deployment, new and larger heatsink cap, motor vibration mounts, the crank wave washers have been reduced to one apart, new integrated steerer and stem adjuster, a pivot back plate, pedal rpm magnet is now removed, a new anti chain-slap module & even the gearbox bearing arrangement had been modified.

There has been much speculation of what is expected for 2016, so as the UK's leading supplier for Bosch electric bikes. Here's a brief rundown of what we expect to see on the latest generation of Bosch eBike systems for 2016. Let's start by saying that Bosch only just saw the flow of Performance drive unit's onto production bikes early last year. This was the biggest advancement from the first generation Classic+ motor. For that reason, we don't expect huge changes for 2016. But we do expect some refinements to the existing system. The beauty of Bosch electric bike systems is that they are capable of being updated. So 2014 / 2015 Bosch eBike owners should see some of the new features on existing systems. There will however be some new hardware on offer: New 2016 Bosch 500Wh Battery One of the most talked about components - The PowerPack. New for 2016, Bosch will offer a higher capacity 500Wh battery alongside the current 400Wh, a step forward for owners with current 400Wh batteries to extend their range. It will be about the same size as the current pack, and from the outside looks much the same. It should fit into the existing frame mounts, so an option for current users to upgrade is essential to extend ranges, particularly for more serious MTB's. It's expected to weigh a little more and obviously sit at a higher price. For this reason, we don't expect all Manufacturers to adopt this into production bikes as it will increase the RRP's and weight slightly on the bike. As the current 400Wh pack gives a decent ride time, we expect it's the longer distance bikes that will adopt this larger capacity battery. This larger battery, with higher density cells will of course take a little longer to charge too. We are seeing figures of approximately 4.5 hours from fully flat to fully charged. Of course as with the 400Wh pack, it can be recharged in situ on the bike or removed from the frame. It will also be available in both Frame and Rack mounted options. We expect to see ranges extended by approx 25% using this larger capacity 500Wh Bosch battery in 2016. As always with Bosch eBike systems they give the most overall lifespan of any eBike systems, being able to cover 60,000 miles or 1000 full charge cycles before capacity loss. UPDATE: Now available for purchase separately here Bosch 500Wh Power Pack. Summary: +Backward Compatible +Increased Range +Neat Design +Long Life Bosch integrates e:Shifting for 2016 Although not totally new, there are certainly some new updates to the Bosch integration of electronic shifting. Used across the board by manufacturers like Nuvinci, Shimano & now Sram too. Electronic gear changes are the latest thing to both mountain biking and trekking alike. Why electronic shifting? Well, there are some positives, like concentrating on the ride ahead more than what gear you should be in. It's also more efficient as the computer can determine the correct gear, instead of the rider selecting, so can also increase range too. It's also simple enough for the non-gear friendly people out there - Leaving the technology to do the work. It also incorporates an automatic downshifting, for example when you stop at junctions, it automatically changes into a lighter gear, so you are already in the correct gear when setting off. We tried this on the Shimano Steps system late last year and it works tremendously well. We expect this to be more widely used on touring / trekking bikes at present, although it will likely cross over to MTB's at some point with electronic derailleur shifting as internal hub gears are not the preferred choice for off road riding. The shifting is cadence based and is optimized for maximum rider efficiency, most systems also allow the rider to enter a manual gear change mode too, should it be preferred. But we think this just defeats the point! Summary: +Improved Shifting +More Efficient +Fully Integrated +More OEM Compatibility New 2016 Bosch CX Drive Unit With improved integration, smaller housing and tweaked output levels, the new 2016 Bosch Performance CX Line motor will support the rider with increased 50 - 300% assistance levels. It also has updated dynamic power control, that smoothes the - now increased 75Nm of torque, into a smoother more, powerful and efficient ride. The direct flow power curve increases assistance across the RPM range, it's also easier going on the drivetrain. The torque is longer lasting and more powerful at higher speeds too. It's also better setup for larger gear ranges including Sram's 10-42 & Shimano's 11-42 gearing. Using a new style 14t front sprocket should also give faster acceleration on a eMTB over the more commonly used 16t. The 2016 CX drive unit itself is essentially a slightly slimmed down version of the current Bosch Performance motor. It should offer better integration and is slightly lighter (approx 200g) due to its compact design and by losing the plastic motor casing we are all used to. Instead the motor is bare - back to the metal - housing, with a high quality black powder coating. This coating is robust, with it's protective lacquer that's safe from corrosion, knocks and is scratch / weather resistant. The cable connections are covered by a smaller plastic protection plate. Depending on how the 2016 CX drive unit is mounted by manufacturers, it could also give a better Q-Factor and slightly higher ground clearance too. It's likely to be easier for full susser's too, as the rear chainstay pivot point can be mounted more direct, giving a shorter back end. Something Haibike for example have already addressed on the current 2015 line up. As the 2016 Bosch CX motor uses the same components as the current system. We expect lots of the above performance improvements to be available for current Performance line motors later in the year through a software tweak. Summary: +More Assistance +Improved Torque +Smoother Power Curve +Lighter Weight Updated 2016 Bosch Nyon Features The Bosch Nyon head unit actually came out on eBikes this year. However for 2016 there will be some software improvements and all new features. This little device currently gives features like satellite navigation, fitness training, ride logging & custom ride modes to name a few (You can read more on that here New Bosch Nyon Display). But new for 2016 comes refinements to Nyon itself, the Bosch eBike Connect Portal (PC based) and the smart phone apps. These extras are mainly on the mapping side of things. We see the ability to be able to plot up to 10 waypoints when route planning and you can see them on the map too when riding. New updates for mountain bike riders in particular include new optimised off road routing. You can also now save routes whilst navigating. So for example you come across a new track, you can start a new recording, then come back to your original route. That's a nice touch & will certainly come in handy! New Places of Interest also appear on maps, so you can navigate quicker and more easily. We (e-bikeshop) will also feature on this as a Bosch Expert Dealer in the UK! Also manufactures will now also be able to set service routines into the Nyon itself. So the user can keep on top of maintenance and servicing should it be required. For 2016 we will see an update to the Topo range, where the user can see the altitude of riding and plan exact routes based on the hills & battery capacity. This should give accurate mileage and make route planning in real time on real gradients a doddle. Probably the biggest update here, and certainly one we get asked about a lot - Finally the user will be able upload GPX format routes via the portal. This really opens up the mapping to everyone and doesn't just restrict to using the Bosch portal to plan routes, many riders already have GPX files from other navigation devices. So this will be a real bonus! Although we are listing this for 2016, it's likely these updates will be available in a few months for current bikes using Nyon. Just to be clear all of the above are software tweaks and use the same current Nyon hardware. It's also worth noting that with these updates, will come a smoother & easier to use front end, it seems to be getting better and more usable with every update! On top of this we predict that the smartphone functions will become more integral, with a music player control and text messages on screen functions will likely be part of the next substantial update too. Current users can update as soon as available by connecting your Nyon device to Wifi and selecting 'Update' within the Settings menu. Summary: +Upload GPX files +Improved Off Road Tracks +Topo Range +Plan Waypoints When can we expect all of this? It's likely that not all manufacturers will adopt these changes instantly. Particularly with tooling costs and the implementation of the Performance CX drive unit. We will likely see some manufacturers using this on the 2016 electric bikes, whilst some may be for 2017. We will expect to see 2016 bikes in around March / April time as usual. Also to note, that the Performance CX motor will probably only initially be on high end eMTB's, it probably won't be too practical for town / road / commuter bikes. This is where the eShifting will come into play. The Current Active line motor will likely follow through on most trekking / town bikes and as suggested above so will the Performance line for some 2016 mountain / road electric bikes. Remember the Nyon updates will likely be available late 2015 and all current bikes can be updated. From previous experience it will probably be possible to flash on a new software update to the current motor systems for some / if not all of the enhancements. What else is on the horizon for 2016? We believe some of the leading Bosch eBike manufacturers like Haibike, Lapierre & Scott to name a few, will adopt various new customised methods of mounting the current components for 2016. For example head unit & battery integration & possible customised / colour coded motor housings, for a more stealthy approach. We also believe that Bosch will unveil a few more ideas, most likely at Eurobike later this year. Considering the manufacturing process, anything further released will likely see its way through in 2017 given the traditional timescales. It's clear that Bosch is at the forefront as the leading eBike system and they show no signs of letting anyone else catch up. What could this be?.. We think a cheaper alternative system will emerge out at some point from Bosch, to compete more with other slightly cheaper systems like Shimano's Steps and Yamaha. Likely for use on lower spec models to offer a more price friendly option to the consumer, again probably looking at 2017 for this. Is it worth the wait? Considering the Bosch Performance drive was only really established late last year and most of the above mentioned will filter its way back down by way of software updates. We think it'll be the more serious / avid riders playing the waiting game for the latest kit.. That said, those guys probably already have current eBikes, so it means they are out riding this summer and already enjoying the great outdoors! Make sure to check back for regular updates. We are heading to go out to Germany in a few weeks time & are hoping to ride the new systems / models. We will further report back then. You can see our current full range of Electric Bike Models. UPDATE: E-Bikeshop first to Receive new Bosch CX powered eBikes in the UK. Click to view the latest electric bikes with Bosch CX on offer. UPDATE: New article for 2017 updates available to read here:- First Look: What’s New For Bosch eBike Components in 2017? Some of the views expressed above are our predictions, they are by no way backed by the manufacturers or suppliers & therefore should be treated as rumours rather than fact. Then again; we tend to be pretty good at this eBike lark - As the UK's largest eBike supplier. Enjoy!
Bosch have been working hard to create a user friendly 'on the fly' charger for their Bosch eBike battery packs. Today we announce the new 12v cigarette socket charger available. No longer do you have to use an inverter to charge your Bosch eBike battery pack in your car. The feedback from more serious customers to Bosch was that they would prefer the ability to be able to charge Bosch eBike batteries from their car. This is particularly useful for midday charges out on the trail or those who wish to charge their battery packs whilst out on the move. The neat new charger works seamlessly with later Bosch Active & Performance batteries, both 300Wh, 400Wh, frame mount & pannier rack mounted power packs. Its the same size as the original small Bosch charger but instead of the mains head on one end it features a direct plug 'n' play 12v socket to fit directly into every vehicles cigarette lighter socket. The cabling is also a lot shorter as you don't need so much length to reach the bike, you can tuck the battery away inside the car whilst on charge. The small unit weighs just shy of 800g and is easily stowable. For older Bosch Classic+ batteries, this new travel charger can also be used in conjunction with the Bosch Classic+ to Performance adapter here. We expect charging to take a little longer than when using ordinary 240v mains. Interestingly the new charger also features an internal discharge protection system for the vehicles battery to prevent it from completely discharging. Also we will take this opportunity to advise all customers to not leave their battery in direct sunlight, especially in the coming summer months, cars can heat up quite extravagantly and leaving your power pack in direct sunlight will cause further heat. Its not good for the battery to charge abnormally hot. So we suggest placing the battery on charge out of the way of direct sunlight and just leave the window ajar to allow a little breeze to flow through the car. In stock today!

So many of you may have used the new Bosch Nyon eBike computer by now, some of you may even own a Bosch Nyon equipped eBike. Learn 10 secrets you may not know about the functionality of the latest electric bike computer from Bosch. Some of this you may already know, but some of it is a little hidden within the Bosch Nyon system itself. E-bikeshop gives you a quick guide of these features. We bet you'll learn at least one thing you didn't know before about the new Bosch Nyon system features! 1) Use 'Ambient Light' for screen brightness Bosch have integrated transflective properties into the Nyon head unit's LCD display. If you haven't noticed, look closely directly above the joystick, there is a small light sensor (Highlighted in red circle below). This detects how bright the screen should be, for example if you are indoors, outside & at night time. You can automatically turn this on within the Settings tab on Bosch Nyon here: 2) Customise your ride screens Did you know that once connected to your smartphone via Bluetooth you can customise your ride screens with any preferential ride data you may want on the Nyon's 'Ride Screen'. This includes many features from Speed, Distance right through to feet climbed. Here's a great example: 3) Set the Home Button to a preferred screen You can actually alter what the 'Home Button' (highlighted below) does when pressed. Go into the settings within Nyon & select your preferred screen to navigate to with the use of the 'Home Button': 4) Use Nyon to map distance by battery capacity Why not make use of the Bosch Nyon's GPS receiver. You can actually produce a map of how far you can go depending on your Bosch battery capacity and current usage. This will re-adjust every 15 seconds and is based roughly on the last mile & riding conditions. To find this go into the 'Map & Navigation' Screen, then scroll right into the sub menu and select 'Battery Range'. Example here: 5) Create your own assistance levels Fed up of the pre set 4 modes? - Eco, Tour, Sport & Turbo. Do you like to tinker? Did you know that you can create your own assistance levels? You can customise up to 4 of your own modes, for example you can create different modes for fitness training or particular routes. Custom assistance modes are indicated in yellow as opposed to the normal blue bars as standard: 6) Automatically reset trip values Resetting the previous trip values before every ride can be tedious. Did you know you can set Nyon to automatically reset the last ride metrics every day at midnight? This wont delete all your map and fitness data, but will reset the basics of the 'Ride Screen' like trip distance, average speed & trip time etc. Do this by scrolling down to 'Auto Reset' within the 'My Nyon' tab in the Settings menu: 7) Use Bosch Nyon to determine effective fitness training When you set up the Bosch Nyon system for the first time, it takes certain physical fitness data from you, the rider. It then uses this data to determine your own personal performance profile. Did you know that all the time you are riding, Nyon tracks both navigation and fitness data in the background, even if you are not using the fitness or navigation features. This is then compared to your stored fitness data & displays the effect of your current physical endurance. Whilst riding this effect is displayed as the 'Training Effect'. This will change depending on the level of activity you are performing during the ride. Handy to keep an eye on because it will even tell you if you are Overreaching. The example below shows that we are 'Maintaining Fitness': 8) Use Nyon to predict your overall cost saving You may have noticed in the 'Dashboard' screen, that Bosch Nyon will track savings on CO2 and monetary values against using your car for example. Although a little gimmicky, you can even tell how many tree's you have preserved!. It goes further than this though, rather than just your current ride, did you know that you can see your overall data, since you very first stepped over your new eBike. To do this scroll right on the 'Dashboard' screen into the sub menu, then scroll to display over longer timescales: 9) Its easier to use your phone to create routes Although the Bosch Nyon display and controls are easy to navigate and intuitive, its much easier to use the smart phone app to create destinations and select routes, with a full keyboard. Did you know you can also preset a work address as well as your home address? Once created, choose if you would prefer a Scenic, Fast or Short route, then fire it straight over to your Nyon using bluetooth: 10) See incoming text messages on screen Once you link the Bosch Nyon system to your smartphone via the application. You can be alerted when an incoming text message comes through directly on the Bosch Nyon Display. This means you'll never miss a meeting again! For safety Bosch won't allow you to read the message until you have stopped cycling, it just alerts you: That sums up our top 10 hidden features of the Bosch Nyon system. Hope you enjoyed the read & most of all learnt something. E-bikeshop are fully trained Bosch technicians both in terms of the mechanical side and the software itself. We have been trained by Bosch themselves on multiple training courses throughout the year. Not tried it yet? Book an appointment with us to come as see this latest tech, or view the full range of Bosch Nyon equipped bikes here. Dont forget to stay glued to our blog for more updates, we are adding articles all the time. We have many more articles already live for you to learn more here. Coming Soon: How to use Bosch Nyon Music Player.. N.B: You must have the 'Bosch eBike Connect' application installed on your smartphone to use features 2, 5, 9 & 10 above. Some features require a one off in app purchase.
So with the new Bosch Nyon system now on our shelves for 2015, a lot of customers are asking if the new Bosch Nyon system can be retro fitted to their existing electric bike? E-bikeshop explains.. We have been testing the new Bosch Nyon satellite navigation advanced display for some time at e-bikeshop.co.uk. Its certainly a revelation in the eBike world, with features like smart phone integration, fitness tracker & sat nav mapping. We have the full article of Nyon features here. Many have been asking if this system can be retro fitted to their existing Bosch eBike? Well today we reveal all, as we manage to reverse fit the custom head unit onto a Haibike that comes as standard with the Bosch Performance Intuvia controls. So it can be done with some Bosch experience! Does Nyon work on all Bosch eBikes? Yes: Nyon will now work with both Active and Performance Line eBikes from 2014 onwards. You can tell what Bosch motor you have by checking the model year first. Most 2014 bikes come fitted with the later Bosch 250w motor. Nyon is not currently compatible with S Pedelec 350w Motor versions. How did we upgrade to Nyon? Firstly we need a 'donor' Bosch electric bike, to perform the upgrade on, we chose the Haibike NDURO PRO 2014 model that comes equipped with the Bosch Intuvia display as standard. Then, the easy bit, we fit a new Nyon head unit display and control buttons by taking off the old controls and installing the new control buttons with the little navigation thumb control on board and Nyon LCD display. Once fitted when you turn the Nyon head unit on; the Bosch system will immediately flash up with an error code. Error 414: 'This eBike is not equipped for the use of Nyon". You cannot operate any of the functions when the system is in this state. Now the difficult bit, we connect to our in house Bosch diagnostics computer and fool the diagnostics into thinking the electric bike comes as standard with Nyon. We can't go into too much detail here but it involves many software remaps to ascertain the correct functionality & container file. The photo above shows the programming in progress once we have the correct software map in place. Once done we can unplug the system, re start it & Voila! We have a working Nyon system on our 2014 Haibike. We have tested this and all functions can be used as new. We can also save the old container file in case you ever want to go back to the original Intuvia display. We can flash the original software back onto the eBike without any problem. When is Nyon available to upgrade? At present Bosch are not supplying the parts separately for users to upgrade their Intuvia displays. The Nyon head unit and control buttons are only available on a warranty 'like for like' replacement to support Nyon users at present if they damage their original controls. We are told by Bosch that this should be possible to purchase separately later in the year. http://youtu.be/jk9pnOmjLqg We will be allowing our EXISTING CUSTOMERS ONLY the option for us to upgrade their current Bosch Performance system Intuvia Display to the Nyon LCD & Controls within our Bosch workshops, by our Technicians. As usual we are not offering this service to anyone who has not purchased their bike from us. For more information why we only serve our customers, please read in the F.A.Q page here. UPDATE: Nyon can now be upgraded for our existing customers. You can upgrade the kit yourself by ordering the complete Nyon display system here. It is also possible to upgrade when ordering new bikes for a reduced cost by selecting this as an option on the bike pages.
On a daily basis I get calls asking what the differences between the Bosch & Yamaha electric bike systems are? What system is better you may ask? Well this is the full article that explains and compares each eBike system side by side. Bosch and Yamaha eBike systems work in a very similar way - They both operate using 250w crank drive electric bike motors. So let's see exactly what the differences are. We will start from the beginning. *** This article has been updated in spring 2016 to accommodate the new revised Bosch & Yamaha systems for 2016 model years onwards *** Who are Bosch? Bosch are a very large multinational company that bring a whole manner of products to market. They began researching and developing eBike systems many years ago, they brought their first electric bike system to market in 2010. The Bosch system has been constantly developed and improved as time has gone on. The latest eBike system is the Bosch Performance line so this is the one we will directly compare today. The Bosch system is now used in over 50 leading bike brands across Europe. Who are Yamaha? Yamaha was founded in 1955 and predominantly built motorcycles for the Japanese market. Today they make anything from eBike systems to Jet Skis with a wide product portfolio under their belt. It was back in 1993 when Yamaha released their first eBike system. This was a massive success. Yamaha now manufacturer over 300,000 electric bike systems a year and, to date, their system is implemented on over 2.7 million eBikes worldwide.In Europe the latest version of the Yamaha system is just used on both the Haibike sDuro range and the Lapierre Overvolt range of electric bikes. Let's compare the components across both systems Battery Comparison Bosch and Yamaha both use 36v Lithium Ion 400Wh batteries. Built using the latest technology to give the maximum range and longevity. Notice how similar they are in shape, also they both incorporate a carry handle at the top.Both batteries have LED lights on board to show the user the remaining capacity. Also the batteries are frame mounted on the down tube. The Yamaha & Bosch batteries lock into place using a key mechanism for security. The difference in mounting is that the Bosch battery slots in from the top down, whereas the Yamaha battery slots in at the bottom first then pushes in from the side. One benefit to this is that the battery can be mounted in smaller frames as there is no need for that extra room at the top when mounting.Also the Bosch battery sits in its own little cradle attached to the frame approx 1 inch up from the motor whereas the Yamaha battery is placed directly into the top of the motor. The Yamaha battery also features a small shock absorber so the battery does not rattle over bumpy terrain. Battery specifications, comparison side by side - Bosch Battery Yamaha Battery Capacity 400Wh / 11 Ah 400Wh / 11Ah Voltage 36 V 36 V Security Key Lock Key Lock LED Status 5 Lights (20%) 4 Lights (25%) Weight 2.6 kg 2.9 kg Type Lithium Ion Lithium Ion Warranty 2 yrs / 500 Full Cycles 2 yrs / 700 Full Cycles Op Temp -5 to 40 degrees -20 to 60 degrees So as you can see from the specs, the Yamaha & Bosch batteries are very similar, the Yamaha is slightly larger in size than the Bosch, the Yamaha battery is also approx 300 grams heavier. The Bosch has 5 LED lights to show capacity in 20% stages whereas the Yamaha battery shows it with 4 LEDs in 25% increments. Battery range in average conditions, comparison side by side - Bosch Battery Yamaha Battery Low 80 miles / 130 km 80 miles / 130 km Medium 50 miles / 80 km 53 miles / 85 km High 37 miles / 60 km 43 miles / 70 km Average 57 miles / 90 km 59 miles / 95 km As you can see the range predictions of each system are very close, the Yamaha system appears to offer a little more in the Medium / High area although this is marginal and they both average very similar. It's also worth pointing out that both Yamaha & Bosch batteries can be charged on or off the electric bike.Both Yamaha and Bosch offer a 2 year warranty on their electrics, Yamaha offer more 'Full' charge cycles than Bosch although remember that this is just the warranty, we expect the battery's overall lifespan to be a lot longer. User Interface Comparison The user interface and controls on each system are very similar in both size and operation. Both units have LCD backlit displays and use an additional button user control for the rider to navigate the settings without their hands leaving the handlebars. The Yamaha head unit is slightly taller than the Bosch display, it's also thinner in design, they both clamp on either side of the stem suitable for both 25.4mm & 31.8 handlebars. The control buttons are similar in size, and clamp on in similar ways. The actual LCD display area is slightly larger on the Yamaha system, each unit is easy to navigate and user friendly. The units are displayed in a clear, easy to read manner. Both head units can be removed from the bike, so when the bike is not in use or locked up somewhere the display can be removed and stored easily in your pocket, meaning no one can pinch it. Where the units do differ is that the Bosch system can be controlled on the head unit itself. You can navigate the settings, reset parameters, turn the lights on and of course power the system on/off. Control unit functions, comparison side by side - Bosch Controls Yamaha Controls LCD Yes Yes Backlit Yes Yes Display Buttons Yes No Control Buttons Yes Yes Clamp Size 25.4 / 31.8mm 25.4 / 31.8mm Removable Yes Yes Walk Function Yes Yes Light Function Yes Yes The remote buttons on the Bosch unit can navigate the information displayed, scroll up and down the assistance levels and also use the 'Walk Function'. The Bosch head unit can be turned on and scroll through the saved parameters when off the bike. The Yamaha display cannot be operated when off the bike, in fact it dims the screen and turns into a pocket watch when removed from the eBike. Obviously the display has no buttons on it so it can only be controlled via the remote buttons when it's connected to the bike. Both Yamaha and Bosch systems have a walk assist mode controlled by the remote buttons, so if the rider is walking beside the bike, the walk function can be used to push the bike along with little effort. Computer parameters, comparison side by side - Bosch Parameters Yamaha Parameters Assist Levels 4 4 Battery Bar 5 Scale 10 Scale Range in Miles Yes Yes Power Meter Yes Yes Cadence Meter No Yes Clock Yes Yes Thermometer No Yes Odometer Yes Yes Trip Distance Yes Yes Trip Time Yes Yes Maximum Speed Yes Yes Average Speed Yes Yes Gear Up Shift Yes No Language Adj Yes Yes Units MPH & KM/H MPH & KM/H Both Bosch and Yamaha displays offer similar parameters on their displays, the only differences are that Yamaha offer a more in depth battery capacity bar, a cadence meter and a thermometer. The latest Bosch Performance software update offers the use of a gear shift indicator for maximum efficiency. The LCD displays a small arrow to the user when it feels you could be making better use of a higher gear. This can be turned on or off in the settings menu.Both Bosch and Yamaha controls have a micro USB output for charging auxiliary items like a mobile phone or gps unit. You can use this cable to convert either Bosch or Yamaha to a Female USB output. Motor Comparison Both Bosch and Yamaha use 250w crank drive motors, they are integrated into the bottom bracket area and drive on the crank which gives full use of the gears and a natural efficient feel for the rider. Bosch and Yamaha use high performance crank drive systems that optimise the use of 3 sensors - Cadence, Torque & Speed. These sensors are measured 1000's of times a second to create a very responsive, efficient & natural rider experience. You will notice both the Yamaha and Bosch motors are similar shapes. They are also similar sizes. In fact the Yamaha motor is slightly smaller than the Bosch. The Yamaha motor is also approximately 500 grams lighter than the Bosch. The Bosch motor is internally geared, so it features a small drive sprocket. This sprocket turns 2.5 times to each crank rotation. This enables a higher ground clearance but still offers standard gear ratios. It's also near impossible for the chain to come off. You will notice the Yamaha motor uses a regular size sprocket and the drive is not internally geared. Yamaha have created this system to be compatible with a double ring set up on the front so you can have a larger gear ratio between the 2 sprockets. The Bosch uses a ISIS crank fitment whereas the Yamaha drive uses a square taper crank fitting. Motor specifications, comparison side by side - Bosch Motor Yamaha Motor Rating 250w 250w Torque 75Nm 70Nm Max Assistance 300% 280% Drive Sprockets 1 1 or 2 E.I Compatible No Yes Light Outputs Yes Yes Assisted Speed 15.5 mph / 25 kph 15.5 mph / 25 kph Weight 3.8 kg 3.5 kg Very similar specifications between both manufacturers. The Bosch Performance CX drive does have a little more torque and assistance in Turbo mode, we list a continuous torque figure but the Yamaha drive will actually peak at a whopping 80Nm!Yamaha advertise a quicker power delivery, so the user doesn't have to get a pedal in. Although the power curve is smoother on the Bosch system. Yamaha call this instant power 'zero cadence', it is there right from the off.Both Yamaha & Bosch systems allow the integration of lighting outputs. Something the Bosch does offer that is not mentioned in the table is a pedal back brake function, although this is not generally used in the UK. The Bosch motor also has gear shift detection so it reduces the power slightly when the user is changing gear to save wear on the drivetrain.On a side note you'll also notice the Yamaha system has been made E.I (Electronic Suspension) compatible. This is featured for the first time on some of the new sDuro Haibike's - the AllMtn RX & the AllMtn PRO. Battery Charger Comparison The battery chargers between Bosch and Yamaha are similar in that they have a low recharge time and are both mains operated 240v chargers. You will notice that the Yamaha charger is longer than the Bosch charger, Yamaha's overall size is a little bigger than Bosch's. The Yamaha charger is IPX4 water resistant.Both Bosch and Yamaha batteries can be charged when mounted in the bike or with the battery removed. When mounted on the bike the Bosch battery is charged through a charging port in the battery holder bracket. When the battery is removed it can also be charged directly by plugging the charger into the bottom of the battery.Whereas Yamaha's battery is charged through the same socket be it with the battery in or out of the frame.Battery charger specifications, comparison side by side - Bosch Charger Yamaha Charger Weight <800g 800g Charge Time 3.5 hrs 3.5 hrs Input Voltage 220-240v 220-240v Input Amps 1.5A 1.3A Output Voltage 32v 42v Output Amps 4A 3.6A Frequency 50/60Hz 50/60Hz Air Vents No No Dimensions L190 W86 H54mm L184 W86 H50mm Charge Temp 0 to 40 degrees 0 to 45 degrees Mains Plug Yes Yes The above recharge times are approx and based on the 400Wh batteries. This recharge time is from fully discharged to fully charged. Each charger can recharge the battery to approx 70-80% in 1.5 hours. Each charger can be used with a DC to AC inverter, for example if you wish to recharge the batteries in a motorhome or car using the cigarette lighter socket (inverter purchased separately). Battery and Motor Integration Compared As previously mentioned the Bosch and Yamaha systems are mounted in very similar ways, the headunit and control buttons are mounted in identical positions. The motors are of course crank drive; so they are integrated into the bottom of the bike's frame where the bottom bracket would normally be. As you can see the Yamaha motor is a little smaller when integrated into the frame, although the Yamaha battery is longer than the Bosch battery pack. As you can also see, the Yamaha motor sits directly into the top of the motor casing whereas Bosch's battery sits in its own holder mounted to the frame above the motor.Both have plastic protective skid plates on the Haibike in particular (not on all manufacturers' eBikes). Notice on the model pictured the Yamaha has the larger chainring and it's a double whereas the Bosch uses the smaller single drive sprocket. Each system gives a similar & good ground clearance. To sum up - What do we think? The specs across each system are very similar, we've explained the exact differences in this article. Having used and ridden both systems there are certain features that we like on both.. Integration and look - We prefer the head unit integration on the Bosch system, it certainly feels firmer than the Yamaha head unit display bracket. The bracket and the cable routing are a lot tidier too. The Yamaha display is a little more flimsy in comparison and the side control buttons feel more 'plasticy'. Hard to explain but the Bosch kit just feels more 'German'. It appears and feels better quality; that said it is a slightly dearer system to purchase. Both systems look pretty good in the way they are integrated into the frames. The Yamaha system does seem a little smaller and more integral to the bike. It's nice that the battery inserts from the side too so that we can offer the system in smaller frames, something which hasn't always been possible with the Bosch system. Also we like the fact that the Yamaha has the small shock absorber at the bottom of the battery to soak up any bumps, although after extensively riding each system we don't feel this is an issue on either. Actual ride time - When it comes to riding the bikes, they are both very much on par with each other and definitely two of the best systems around. The Yamaha certainly feels a little more powerful in respect of torque, with the power coming in just a second or so earlier than the Bosch motor, although when both motors are up to a decent RPM they feel just as efficient as one another. We like the fact that the Yamaha system allows the use of 2 chainrings at the front. Although we don't feel it essential on a crank drive electric bike, some users do prefer to have a larger array of gears, particularly when using the bike off power. However we can see why Bosch have opted for the smaller single ring option to increase ground clearance and make it near impossible for the chain to come off. Both systems are very easy to use, ride and navigate through the various assistance levels & functions on board. We like the fact that Yamaha breaks down the remaining battery capacity into more increments, it gives the rider more of a sense of what is remaining. But both work well in comparison to other systems on the market. Although the Bosch display breaks down the assistance levels to 4 as opposed to 3 on the Yamaha, we didn't feel that this had too much effect in the actual riding. That said we were comparing the 2 systems off road, an extra level of adjustment on the Bosch display could possibly come in handy, for longer distance touring for example. Small factors worth mentioning - The ISIS crank axle is our preferred mounting method for the cranks to the motor axle. The Bosch motor uses the ISIS drive setup & the Yamaha the square taper type. We much prefer the size of the Bosch charger as it's smaller than the Yamaha and would be easier to carry around to extend any range. The Yamaha charger is just a fraction on the large size for our liking. Also the Bosch charger has little rubber feet on the bottom, which is such a small factor but it stops it sliding off the workbench as easily. Worth pointing out that the Bosch system can be updated by the dealer via the USB diagnostics socket. We like this because it means future updates are always possible and likely to bring new features. The Yamaha system is set out the factory and not updateable. Bosch or Yamaha - Which is better? Now that's a toughie, again there are certain features we like on each system, we would suggest, rather than buy a bike dependent on the drive system used, steer more towards thinking about the style and specification of the electric bike that you require. You may even end up with 2 very similar bikes one using Bosch & the other using Yamaha. At this point it's time to give us a call and book an appointment to physically ride both systems, also have a look for yourself at the quality and integration. You can then make the decision as to what suits your requirements better. You'll be impressed with both Yamaha & Bosch eBike systems, as are we!

We are proud to announce that e-bikeshop.co.uk have a working tuning dongle kit to derestrict the 15mph cut off speed on all Yamaha powered electric bikes. For the past few years we have been extremely successful with our exclusive Bosch tuning kits that derestrict the electric bike so that you can reach assisted speeds of over 15mph.We can now use similar technology on our new Yamaha eBikes arriving shortly. These kits work in a similar way but plumb in differently. Not something you have to worry about as we do the hard work for you for free! How does it work? Basically the Yamaha speed tuning dongles trick the system into thinking its going half as fast as it actually is. This allows you the rider to pedal past the 15mph barrier and reach speeds up to 30mph assisted. Although a simple format, the technology behind it is a little more complicated! But you need not worry. How do you use it? All you have to do is plug it in when you want the bike derestricted. We plumb the wiring kit into the Yamaha bike before it leaves the workshop. Can you revert it back to normal? Yes of course, just unplug it. The cable kit remains but the bike reverts back to normal. When you want it to go faster just plug it back in. Where can I use the Speed Tuning Kit? Obviously the UK law states that eBikes should only be assisted to 15mph. Therefore the speed tuning kit is strictly for off road (private land) use only. Are there any side effects to using the kit? Yes the speed is halved on the display, therefore you have to double it for a true reading. For example if the display reads 12mph, you are actually going 24mph.. Simple! When you unplug the dongle it reverts back to standard. Why would I want to go faster than 15mph? Really the question is why not?.. But in all seriousness, it can be frustrating hitting the 15mph barrier, particularly off road when you are really going for it and the assistance backs off. Also a lot of people can average faster than 15mph, therefore the majority of their ride the rider is just riding a slightly heavier bike around with no assistance. The Tuning kit is the answer to sit at a comfortable speed assisted. Can I retrofit this to my Yamaha eBike? No, the tuning kit is exclusively available to our own customers. Just add the Yamaha electric bike of your preference together with the tuning kit to the basket, your bike will be set up with the tuning kit installed prior to leaving our workshops. If you decide not to get one at first, this is a not a problem, as long as you have your original bike sales receipt from us we can fit one for you at a later date, maybe free service time? Can I order the Yamaha Tuning Kit on its own? Yes you can, however, it will not be dispatched. It has to be fitted by our workshop technicians exclusively on our own eBikes. Remember you can unplug it, so to save a journey you could have it fitted from new, but unplug it for your first few rides. Then plug it in when you are comfortable with how the eBike performs. The Yamaha Tuning Dongles can be found here.Or why not take a look at our full range of Yamaha powered eBikes here.
Breaking News: We @e-bikshop visited Haibike in Schweinfurt to be one of the first to be introduced to and test the new Yamaha eBike system. This will be coming to the UK in the new 2015 sDURO electric bike line up. This new Yamaha system results from Haibike uniting with Yamaha to bring a whole new product range to the market. More can be read about this here - Haibike unite with Yamaha to bring new eBike system to European market. Scroll to the bottom of the page to view the exclusive prototype images e-bikeshop took whilst in Germany. Yamaha new to the Electric Bike scene? Yamaha have been in the eBike game for a long time, over 10 years in fact! They were one of the first manufacturers to introduce a crank drive electric bike system. But they never really left Japan. Yamaha actually has 53% of Japan's market share and had to date has produced over 2.7 million systems. So they really know what they are doing! Basically what we are getting at is although they seem fairly new to us, in Europe, they have been tried and tested and developed over many years to bring a whole new system to market. Yamaha eBike Series Overview Although already established in the market in Japan, the Yamaha eBike system has now united with the Winora Group (who own Haibike). Haibike have developed the new system alongside Yamaha to make several changes in terms of battery mounting and integration. Winora will also act as the service partners for Europe & will offer full service support, warranty and backup spares. The freshly developed system will be found in the new Haibike sDURO line up of eBikes for the 2015 season. Let's talk a little more in detail about the new Yamaha system and some of its features. We will break it down into the individual components. Yamaha Drive Unit The new Yamaha eBike motor is small and compact for a crank drive unit. It weighs in at just 3.5kg making it one of the lightest motors available on the market today. Yamaha have made the motor very unit slim and allowed the use of both single and double rings. This is handy for anyone looking for that extra gear on the climbs! The drive unit is a 250w motor, so it complies with European law. It offers support up to 25 km/h (15.5mph), obviously the rider can travel faster but with no further support from the motor beyond this speed. The new Yamaha drive unit offer an impressive 70Nm of torque which is claimed to actually peak at 80Nm! This is one of the most powerful units on the market and certainly packs a punch straight from the off. Also power is delivered in less stages than other systems to the crankshaft meaning there is no 'extra' gearing within the motor, so it can pull all this torque instantly. This also helps keep the actual overall size of the motor to a minimum. Yamaha market this as a '0 Cadence' system, meaning you do not have to get the motor up to speed with a few pedals, the power is there, instantly, every time. Yamaha Battery and Charger The charger is water resistant and operates at a frequency of 50/60Hz and allows an input voltage of 220-240v. It outputs at approximately 42 volts at a current of 3.6 amps. Although the prototype charger we handled had a European plug head, we are told by the product manager that by the time of release it will be available with a UK plug for the British market. The new Battery Pack from Yamaha has been totally redesigned. Haibike have been working with Yamaha for the past 2 years to develop the shape and integration of the battery. You can view how the battery is integrated in our exclusive gallery below. Interestingly Haibike have developed the Yamaha battery so that can be inserted from the side. This is a big improvement allowing the battery to be more integrated into smaller frames and does not have to allow a couple of inches of space above the battery to clip it in. The battery is available in one variant - 400Wh (11A). Interestingly when we probed the product manager about the true capacity of the battery pack, he said that most of the batteries were actually coming out at approx 420Wh, but they list them as 400Wh to be on the safe side! We learned that the battery had been tested for range on the 'Official Extra Energy Testing Route' in Germany. This route is made up of hills, mixed terrain and stopping and starting. The range figures are then published based on these findings, so they can be fairly accurate and not over exaggerated. So as you can see the estimated range is 130 Km (80 miles) in 'Eco', 85 Km (53 miles) in 'Standard' & 70 Km (44 miles) in 'High'. This range is really good and just shows how efficient the new system is. This Yamaha battery pack weighs in at just 2.9Kg, so like the motor it is one of the lightest units on the market. As expected the battery pack has 4 LEDs built into the pack to tell you the capacity. Another new feature of this battery is that it features a bump stop on the bottom mount, a small rubber suspension system that keeps the battery in place over even the roughest of terrain. The Yamaha battery carries a 2 year warranty and takes approx 3.5 hours to charge from flat. It can be charged both on and off the electric bike. Yamaha LCD Control Unit and Buttons Haibike have opted for the latest generation of the Yamaha head unit. It has a large removable LCD display screen that relates back all the necessary data & statistics. This new LCD display is backlit and ensures all the relevant data is relayed back to the rider in an easy to read and clear environment. It's very simple to use and the screen itself has no buttons on it at all. The rider controls this from the left hand control buttons. The buttons allow the assistance level to be selected with the up and down arrows. The assistance levels range from 'Off' (non assisted riding), 'Eco' (100% support), 'Standard' (190% support) & 'High' (280% support). The controls allow the use of a 'Walk Assist' mode, a power button to turn the system on and off, the 'S' button which scrolls through the LCD data & also a light activation button for trekking models equipped with lights. The Yamaha user displays the important data whilst out riding including - a power meter, range left, time, cadence, assistance mode, speed, temperature & battery capacity in a 10 scale bar and also percentage. In all the display is very easy to navigate and operate using the control buttons. It certainly makes things easier than taking your hands off the bars to navigate through the settings. The display mounts above the stem in the center of the cockpit so it is out the way of the rest of the controls and easy to see whilst riding. When removed from the bike it acts as a pocket watch.

Bosch announces their new Nyon eBike controller for 2015 / 2016. The new Head Unit will run on the current Performance eBike motor system but will be built with a larger screen and some all new features! Here we give you a brief overview of the new features and benefits in this latest eBike tech...The new Nyon system is the latest advancement the German manufacturers Bosch have been working hard on, it was announced at Eurobike last year to gauge interest from both suppliers and end users alike. The system went down well as the first all in one eBike computer that can perform navigation, fitness training/mapping & smartphone integration.The new head unit is to work on the Bosch Performance system, it mounts in a similar way to the current Intuvia display although this one features a much larger 4.3-inch colour screen and hosts a few new buttons; both on the display and the separate handlebar control unit to make operating the new features easy. Let's break down some of the new functions featured on the Bosch Nyon system... Bosch eBike Navigation - Nyon has a new built-in navigation system designed specifically for cyclists in mind. The maps are based on the Wiki Open Street Map platform. This is integrated into the new Bosch unit with GPS so it can perform live maps in both 2D & 3D styles creating a full user-friendly navigation device directly on your eBike powered from the Bosch battery.Interestingly the mapping doesn't just show directions but calculates the best route possible by eBike. This means that you can take more direct routes that might not be possible by car. Another adoption is the range indicator. This calculates not just range left but also factors in your route, topography & your personal riding style to indicate clearly indicate on the map how many miles you have left in the battery. Neat huh?Quick demo of the unit in action here - Smartphone Integration - The new Bosch Nyon system is designed with the latest integration for smartphone users. The idea is that you can leave your phone in your pocket and the Bosch system will connect to your smartphone via Bluetooth. This brings with it lots of new neat features that allow your phone to connect with your Bosch eBike. For example, you can control what music is being played on your phone directly from the Bosch Nyon head unit itself.If you are riding and get an incoming call, the Bosch system will present this to you on Nyons new super slick screen. It will show you who is calling so you can be in full control. If you get a text message it will even pop the message onto the large screen to say who has texted and the message itself. This means there are no excuses for not seeing that all important message!While we are talking smartphones, Bosch tells us that they are going to release a new mobile app so you can perform multiple tasks on your phone that affect Nyons user interface. For example, you can set up things like a 'Favourite Screen'. eBike Fitness Training - Alongside the new Bosch Nyon eBike system, Bosch will release their 'Online Portal'. This means users can pull up all their latest eBike data up on their home computer. This is a really neat feature, it will allow you to track the progress of your recent routes and share them with others online. By connecting a heart rate chest strap via Bluetooth to Nyon you can use the system as a fitness training tool. This will not only track your ride but combine them with signals such as your heart rate so you can progress with your fitness training all in one place.By combining data such as your heart rate & cadence the system can measure your eBiking performance and calculate your progress in the form of calorie consumption and training efficiency. The Bosch Online Portal will present all of this data to you in the form of nice graphics charts and maps of your ride.Check out this video for a short demo - User Interface Customisation - Above we have mentioned lots of new neat features of the Bosch Nyon system. There have also been certain advancements in the user interface with regards to user customisation.With each screen, you, the user, can customise the layout to your preference. This is really good as it means you can get all the data available in the format you prefer to see and read. We mentioned the mobile app above & this will allow you to alter things like a favourite screen, this is really important so you're not just stuck with one layout.On this new Bosch eBike system, for the first time, the motor assistance can be adjusted by the end user. This means you can add up to 5 riding modes which can each be set individually. So you can actually fine tune the motor assistance levels that support your riding, this has never been possible before. Conclusion - We @ e-bikeshop are very excited for the release of the Bosch Nyon system. Some of the features detailed above are a vast step forward in the eBiking world. This is the first system to integrate all of the features through an 'all in one' system.No longer do you have to run mapping and fitness apps on the side, everything can be operated in one place. To top it all off all of the functions can be operated on the 4.3 inch backlit display which is easy to read in all light conditions. We expect these features to be very useful on a eBike and we are sure that Bosch will make a tremendous job of making it all function well as is already proved on their current eBike system lines.We will be visiting Bosch later on in the year to test the new Nyon device and we will have some more feedback to report back once we have done this. When can we expect to see this tech on new eBikes?.. At current, there are only one of these systems in the world, built as a prototype to demonstrate the new functions. We expect it will be a while before Bosch produces this on a mainstream level and then filter down the chain to the eBikes on our shelves.The system may feature on some 2015 model year eBikes but more likely it will be the 2016 model year lines that take it on fully. Bosch tends to test their products extensively before taking them to market. Whereas some manufacturers bring out a product to test and refine on the market by the end user. The German manufacturer Bosch always make sure their products are 100% before the end user gets their hands on them.Please note: this new Nyon system is just a head unit change. It operates using the current Performance motor and Battery Pack. We can't be sure yet if it can be retrofitted. But the current Bosch Performance line Motor and battery will be powering this display.Expect a full review on here, so watch this space.To view all our latest Bosch powered eBikes please click here
A lot of people ask me - What exactly is the difference between the Bosch eBike 250w motor and the Bosch S 350w motor? So I have decided to make a little write up to provide more details and have all the differences explained, it should also save me a fair amount of time on the phone each day too! So to start off the Bosch 350w S motor on paper is more than the 250w.. Right?.. Yes. However, don't look at this as top trump cards and decide you need a 350w Bosch motor otherwise you won't be able to get up that huge hill you live on top of. Did you know that both the 250w and the 350w Bosch motor are exactly the same? They both share the same internals, they both use the same battery & head unit etc. Some rumours have spread that the 350w has 'metal internal gearing' and the 250w motors do not, again this is not true, both motors are produced using the same components. So exactly what is the difference you may ask? Well, they are programmed slightly different. The 350w speed pedelec has an assisted speed to 45 km/h and the 250w motor is assisted to 25 km/h. Everything else is exactly the same. The maximum and minimum assistance levels, the maximum torque & the motor RPM all stay the same between both types. Oh and the 350w motor has a Red Bosch logo on the side whereas the 250w has a grey logo, so they are easily distinguished.Also, it's worth noting the new CX line developed with more torque and assistance (not available in the 350w version. See the table below for factual differences:- Bosch Performance 350w Bosch Performance CX 250w Assistance 275% 300% Torque 60Nm 75Nm Assisted Speed 45 km/h 25 km/h (50 km/h Tuned) So whats the point in 2 drive types? Its simple.. One can reach higher assisted speeds than the other. Who uses Speed pedelecs? Some European countries have guidelines and procedures in place for Speed Pedelecs (eBikes over 250w & 25 km/h). For example in Germany certain laws allow you to register your 350w eBike and pay a yearly rate to ride a Speed Pedelec on the road. There are certain rules that stipulate a cycle helmet must be worn, the eBike must have a side stand, lights and a licence plate holder. Over here it is classed as a motor vehicle so you would have to be licensed and hold appropriate insurance. There is currently no regulations in place to license a Speed pedelec.It's worth noting at this point that the German market is way ahead of us here in the UK. So if their market is so advanced and they have regulations in place is everyone on an 'S' pedelec? You would think so, however, you'll be surprised to hear that out of the 400,000 electric bikes sold annually in Germany, only around 5,000 of these are Speed pedelecs. Only a tiny percentage ey? Is it illegal to use a 350w Bosch motor here in the UK? On the road... Yes (Unless you take the appropriate actions to license the eBike). You may wish to use the eBike on private land with the permission of the land owner. If you do use a 350w motor here on the road, you are riding your eBike illegally. You do run the risk of having your eBike taken by the authorities. If you are involved in an accident, you are responsible for the damages/injury involved for both yourself and the 3rd party. So I want a 250w Motor but how can I go faster? We do provide a Bosch speed tuning dongle for all of our Bosch powered eBikes. This is a device that is 'plumbed' into the motor that can alter the speed cut off of the eBike. It allows you to travel as fast as you want to be assisted by the motor off road (private land) of course. This can easily be unplugged when you are on the road, then easily plugged back into derestrict as required. By using a 250w motor it means that you have a legal bike that can be easily derestricted when needed. Remember the 250w Bosch motors give exactly the same assistance and torque levels as the 350w motors. In fact, a 250w motor with a dongle installed will travel at faster-assisted speeds than a 350w motor on its own. Crazy huh!?A little more can be read about the speed tuning dongles here - How to derestrict a Bosch Electric Bike. Also, it's worth noting that we are only supplying dongles for our own eBikes with the latest Bosch eBike motor.
I previously blogged about the New 2014 Haibike Trekking SL electric bikes we have arriving shortly (Jan) 2014. But these eBikes were worthy of another blog post. The reason being they are not only the only Haibikes but also one of the only eBikes out there to feature the Sram Dual drive with 27spd. Now we all know that the Bosch eBike system is only capable of running one chainring on the front. This then only leaves the rear sprockets to play a part in the gearing, commonly 8, 9 or 10 speed. This is where the Sram Dual Drive comes into play, the basic concept is to use a 3 speed hub gear and then mount a 9 speed cassette onto the outside. This then allows the user the whole 27 gears, giving a much wider range. It's a unique system that combines the 2 types of gear system we know today. Both the hub and derailleur gearing are controlled off the same shifter, meaning you can change all 27 gears with just one hand and one set of controls. It's really simple. This gives a massive range and is ideal for trekking / commuting / touring / hybrid style electric bikes. The gear hub can be shifted at any time, even under load or standing still. The cassette provides a wide range of gears for maximum versatility. It's built for the rider who needs lots of gearing options for touring or hilly terrain. Haibike have incorporated this system onto their Trekking SL models, available as a low step or cross bar model - Crossbar Model - Haibike xDuro Treking RX Cross 2015 , Low Step Model - Haibike xDuro Treking RX Low 2015
We at e-bikeshop have been supplying the Bosch tuning dongle for many UK customers over the past year or so. With the introduction of the new Gen2 style Bosch eBike motors, rumours have been spreading that the tuning dongles will not be compatible. Don't worry we are way ahead of the game and have been testing the speed derestriction to make sure it is working and performs just as before. With the Gen2 style Bosch eBike's arriving shortly we wanted to let people know that we have created a tuning system that works on these new style Bosch motors. The technology is similar to before but we use a different cable system to integrate it into the Bosch eBike. Once fitted the new dongles operate in exactly the same way as the previous Classic + Dongles did. You can read about our Classic+ Line Bosch Tuning Dongles by clicking here. The major difference is that we now only supply the Gen2 Bosch Motor Tuning Dongles on our own electric bikes. So therefore if you require a dongle and Gen2 eBike please let us know, these fit all of Bosch electric bikes, with the Active or Performance Bosch type motors & 250w or 350w. The new Bosch motor dongles will not be available to buy separately. If you have bought a Bosch eBike from a 3rd party there is no option for you to purchase one of our Gen2 dongles.. You may wish to contact us to place an order, or alternatively please add the Gen2 eBike into the basket, along with a dongle. We will then fit the dongle prior to the electric bike leaving our workshop. You pay for the dongle but the fitting labour is free of charge when placed with a new eBike order. The speed tuning dongles are for off road (private land) use only. Here is a independent customer review after having the dongle fitted - Bosch Tuning Dongle Customer Review Here is a direct link to our electric bike range from Raleigh, Moustache and Haibike - https://www.e-bikeshop.co.uk/Electric-Bikes-UK-Dealer Here is a link to our speed tuning dongles - https://www.e-bikeshop.co.uk/eBike-Spare-Parts/bosch-ebike-tuning-dongle
The PowerPacks used on Bosch powered eBikes are amongst the most advanced batteries currently on the electric bike market. They offer a superior range, reliability & longevity compared to many other batteries. However this all comes at a price; with a replacement currently costing around £500+. Some people are put off by the price of a replacement battery, thinking that it will have to be replaced every other year, but this is not true. Bosch actually guarantee their batteries for 2 years or 500 charge cycles (whichever comes first). This doesn't mean your battery will pack up after 2 years and 1 day. In fact Bosch themselves state that the battery should be good for around 8-9 years or 1000 full charge cycles. After 1000 cycles the battery will still work, but any battery will age over time so it will start to lose capacity and therefore not power your electric bike so far. Also I would like to point out that many people think that a part charge counts as a full charge cycle in Bosch's terms. Well it doesn't, if you just top the battery up a small amount, only this is recorded and will not be counted until there are enough of these partial charges to count towards a full charge cycle. When a Bosch powered eBike visits our workshop we can use our diagnostics tool to read into the battery itself. The Bosch battery is very clever and records many different parameters, these are then saved within the system for us as a Bosch eBike dealer to consider. We can tap into the system and see exactly how many 'Full Charge Cycles' this particular battery has had. We can also view many other parameters for example - maximum / minimum battery temperature, charge state, usage etc. etc. Interesting stuff eh? Anyway back to the point.. Certain measures explained in this article can help you look after, extend the life of your eBike battery and keep it well maintained. OK so here are some of the most common questions we hear regarding Bosch batteries (It's the easiest way to structure the article) - I have just received my brand new Bosch eBike, what's the first step? If your eBike came from us, we normally charge the battery fully just before letting it out of the workshop as we know you'll be itching to ride it the minute you receive it. However if your battery arrives partially charged then it's best to charge it fully before the first ride. This helps condition the battery and gives it a start point from which to gauge the rest of its operation. How often should you charge your Bosch eBike battery? The new Lithium cells used within the Bosch battery packs are very advanced. Unlike the older style batteries where you had to completely discharge the battery and then fully charge it back up again to avoid any damage; this is not the case on the Bosch PowerPacks. In fact it's much better to just top up the battery after every trip. So if you have just cycled 10 miles on your electric bike, it's better to top it back up to full when you get home rather than incorporating a few trips before charging back fully. Should I keep my battery clean? Yes of course it is good to keep any component of your eBike clean. Although this will not affect the internals of the battery at all if the exterior case is dirty. The best way to clean the battery, or any components of your electric bike for that matter, is with a wet sponge or low pressure hose. A typical garden hose is perfect at washing away grime without applying too much pressure. Although the Bosch batteries are weather proof it is never advised to use any sort of high pressure jet / pressure washer on your bike. This pressure can force water into the battery case itself and cause problems. It can also force water into other parts of your electric bike where you don't want water to exist (motor, bearing internals, suspension seals etc.). So although it may be quicker to clean please don't use pressure washers at all. I may as well use this opportunity to stick a plug in for our Bosch Battery Covers to keep it clean. Will my battery range be affected if using a inverter in from my vehicle or motor home? - No, you can use inverters to charge your electric bike for example from the cigarette lighter port in most cars. This can be handy if you are out and about or wish to charge on the move. But please make sure that the inverter itself is rated for the correct output for the Bosch charger. You can normally find all of this information on the inverters packaging or on a sticker on the inverter itself. The Bosch charger is designed for a rated voltage between 207 - 264 volts with an output of 42v. The charger only charges the battery at a low 4 amp current so is fine for most inverters and car batteries. Please check these values to make sure the inverter is compatible before plugging it in. Also remember depending on the inverter itself that the battery may take a little longer to charge than if it was plugged into the mains. Most importantly of all make sure the vehicle engine is running whilst the battery is on charge because it could drain your vehicle battery faster than you think. Will it reduce my battery life if riding in very harsh conditions or using full power a lot? Remember the power of the motor can peak at 500w so can draw power from the battery quicker and put a higher load on it. Think of it this way; the harder you use your eBike the faster the battery will discharge. The faster it discharges, then the more you will be charging it back up. This means that you could end up performing many more charge cycles than someone who is using their eBike lightly in the same time period. After a long time the capacity of the battery will gradually drop. So you could be replacing it sooner if riding the bike very hard for the majority of the time. I would recommend using an assistance level that works for you. Many people (mainly adrenaline junkies / blokes) could use their eBike flat out in the maximum assistance mode 'Turbo'. The eBike will use more power and therefore you will get a shorter assisted distance out of it. Quite honestly you don't 'need' to use the eBike flat out in 'Turbo' all of the time (I can't deny that this isn't fun though!). I have actually found to use 'Eco' & 'Tour' modes for the majority of my riding is more than enough, with 'Turbo' mode assisting me on the very toughest of climbs. Obviously everyone's fitness levels are different so you will need to work out what works for you, it is far too easy to hit 'Turbo' mode for the majority of your ride. The bike wont go any faster (mph) but it will have more 'grunt', in fact the eBike will only go as fast as you pedal, it's just the amount of assistance the motor gives you that changes. I'm putting my eBike away for the winter, will this damage the battery at all? No, we know that some less keen (fair weather) riders may not want to cycle through the cold, wet and grim UK conditions found in the winter. You can store your eBike away, it's not a problem; however there are some steps you can take to keep your battery healthy during these times -If you are keeping your eBike outside in a shed or garage, then it's always best to bring your battery indoors. The Bosch batteries are capable of being stored in temperatures between -10 through to +60 degrees centigrade. But the cells don't like to be stored in very low or very high temperatures. In fact the best possible temperature for storage is room temperature. Around 15-20 degrees is perfect. So the eBike can stay in the shed but bring the battery inside with you. Once in the house at room temperature, store the battery in a dry and secure place. Sticking it on a shelf in the kitchen above the kettle runs the risk of moisture travelling up from the kettle and into the battery case. The perfect place is tucked away in a cupboard where its kept at optimum temperature, away from moisture and where it's not vulnerable to being knocked at all. I know it can make a very good door stop, it's tempting; but you'll end up tripping over it. It's not good for your battery, not good for your toes & certainly not good for your partner when they hear profanity from your mouth! When storing your eBike battery for long periods of time it's best to keep the battery partially charged. If you store the battery completely flat then you run the risk of damaging the internals of the cells themselves. Also if you store the battery fully charged this can leave the cells under more pressure. So it's best to keep the battery stored in between. For the Bosch battery in particular the optimum charge state to leave it in is 60% (Or 3 LED's lit on the battery level indicator). For very long periods try to check the capacity every 6 months or so. When the battery reaches 1 LED showing, then top it back up to 3 LED's again. Many people think it's best to keep the battery on the charger so its always topped up in storage, but this is simply not the case. The Bosch charger won't 'overcharge' the battery at all but again it does leave the battery under more pressure. Will it harm the battery if I run it completely flat on a ride? No, it's never recommended to run the battery completely flat, but for longer rides it obviously can happen. The Bosch Battery is protected by its on board BMS (Battery Management System). This means it's protected for deep discharging, the BMS won't allow the battery to run completely flat. It may seem that you have no power left, but the BMS will have already shut off the power to the motor before it can hurt itself. We all know that the beauty of the Bosch drive is you can still ride without any resistance with the power switched off. On a side note here, if you are running lights directly powered from the Bosch motor and you do run out of power, the BMS will allow a small amount of power still to the lights so you will still remain visible! I ride in very cold conditions during the winter will this affect battery life? The simple answer is yes. Cold or very hot conditions can affect your battery range considerably. Bosch say it can be affected up to 30% in sub zero conditions. So if you are consistently riding in these conditions it can really affect not just your range; but the battery has to work a lot harder to perform the same function, this will decrease the overall lifespan of the battery as well. There are certain actions you can take to prevent this. You can wrap your battery up to keep it to temperature. Some people use a sock, some knit a woollen jumper for it, we actually provide a perfect neoprene Bosch Battery Cover that really hugs all styles of the Bosch battery to not just keep them within temperature but can keep the battery clean, protected from knocks and out of direct sunlight. You can buy this from our shop by clicking the link above. Should I clean the connections between the Bosch Battery and the eBike itself? Yes it is always good to keep these connections clean. This can minimize the risk of short circuit and damage to the battery itself. My advice would be to clean the battery mount connections on the bike with a cloth and if you are feeling really adventurous apply a small amount of grease (or Vaseline for the less handy users). When I say a small amount i really do mean a small amount, just a tiny bit to wipe over the connectors to keep them from corroding, its not good to plaster these with grease. It will not help at all. All it will do is attract more dirt and dust from the terrain which will stick to these connectors. I would not suggest to play with the connections on the bottom of the battery itself as you run the risk of short circuiting here, although 36v won't kill you it could make your hair stand on end and your wallet will end up £500+ lighter. Should I remove the battery when transporting my bike on the bike rack of my car / motor home? Yes this is strongly advised, stick it in a dry & safe place inside the vehicle. Here it is less likely to get knocked and lessens the chances of the battery flying off the electric bike on the motorway if it's not secured properly. The motorcyclist travelling behind you will not appreciate this hitting his visor. The best place to store the battery is under the driver's seat, this means it's out of the way and also shouldn't move around too much. Wrap it in a towel to prevent any knocks. Do not leave the battery on your parcel shelf, if you end up braking hard, the 2kg+ battery is the last thing you want hitting you in the back of the head. It will leave you with a headache! Also by storing in within the car it keeps the battery from getting wet. Although the battery is rain proof, people don't realize that if you're travelling at 70mph down the motorway, the water & air travelling over your car is then doubled in speed as it wraps round the back of your vehicle. This means the battery could be being sprayed with water at around 140mph. This is stronger than a pressure washer and can force water into the battery and components of the eBike itself. While I'm on this topic it's advised to use a cycle cover on the eBike and secured down safely. I dropped my Bosch battery and the case is cracked what shall I do? If your Bosch battery is damaged in anyway then it should be replaced. Even if it seems OK on the outside one of the cells inside may be damaged, this can then move onto other cells and the whole pack can become a ticking time bomb. The battery could seem fine and work but weeks later the effects of the damage could become apparent. The battery could heat up or even ignite. Do not under any circumstances ship this battery anywhere, you could be responsible for a DHL truck travelling down the motorway on fire! You should have the old battery properly disposed of. A faulty Lithium cell can reach temperatures of 1000+ degrees. It's really not worth the risk, visit a Bosch dealer and have it replaced. If your battery was damaged and did ever ignite, then get it outside immediately, the best way to put out a Lithium cell is with water and lots of it! Be careful to never inhale fumes from a burning battery as this can burn your throat. Anyway let's get back on topic.. I have had my Bosch eBike a while now and it's not going as far as it did when new, does the battery need replacing? Yes, quite possibly, but not always. There may certain other factors causing this -Are your tyres inflated correctly? It's important to keep your tyres inflated to the correct pressure as stated on the side of the tyre. It's amazing how much effect this can have, in fact a tyre that is half the pressure it should be can affect your range up to 40%! So check them every couple of months and inflate as necessary. When was your eBike last serviced? Something as simple as a brake pad rubbing can slow you down considerably. With the extra assistance on an electric bike, you may not even notice the extra drag. But the motor will be working much harder to assist you and therefore will drain the battery faster. Its best to get your eBike serviced once a year to keep it in good shape which can rub off well on your battery. Already described above, but you may notice this during the winter. If the range is significantly reduced, it could be because the battery is operating in much lower temperatures. Buy one of our Bosch Battery covers to help prevent this. Your battery could possibly benefit from a complete conditioning cycle, this allows the battery to re-learn its full capacity and charge state. Please read the topic which is covered further down in this article. My battery needs replacing, what shall I do? It may be that none of the above factors are affecting your battery. It possibly time to call it a day and have the battery replaced. But to be sure you should have the capacity of the battery checked first, just to make sure. If you are not competent with a testing meter I do not advise poking around on the Battery connections to test anything. You could easily cross two of the connectors and be in for a shock, you could destroy your battery this way too. You should visit a Bosch dealer and have the battery capacity checked properly. We won't take a meter near it, we will plug it into our computers and be able to give you an decision straight away if the battery needs to be replaced. On request we can also print diagnostics reports for your records. When a new battery is purchased it comes with a new Warranty from a Bosch dealer, so be sure to keep the receipt of purchase date safe. Can I open up the case & replace the cells myself? Yes of course it's your battery and therefore you can do what you want with it. But there are various reasons why this should not be done -There is risk of short circuiting, burning your fingers, fire and even harmful acids. Batteries are assembled in strictly controlled environments by specialists to ensure maximum safety. Going at with a screwdriver in the garden shed probably won't end up well. As soon as you open it up, your warranty will be void from Bosch and the CE certification from Bosch will be invalid. This also holds you responsible if you or others are harmed by the battery in the event of a future problem. Fitting an aftermarket battery or new internal cells not only could harm others but could harm the rest of your electric bikes components. You probably won't be able to achieve this anyway as the battery is very intelligent and the on board BMS makes contact with the rest of the Bosch system. The chances are you will probably waste money on new cells or the new cells will be a cheap Chinese imitation and won't last very long anyway. It's really not worth the risk. Should I perform a full conditioning cycle often? No, the Bosch battery is very intelligent, the on board BMS takes the hassle away to make a really user friendly battery. All you have to do is charge it and the Bosch system will take care of the rest. The BMS will self balance the cells when charging, it will control everything from deep discharging, over charging through to short circuiting. If you do wish to perform a full conditioning cycle then you can do this by simply discharging the battery completely by riding it until it is flat, then charging it back up fully with no interruptions. This can be done twice in a row to make sure it has fully conditioned. This is not recommended to do all of the time. Once a year is sufficient but like I say above it's not necessary in most cases. To conclude The main points are - Top the battery up, keep it at a good temperature, make sure the overall eBike is well maintained & keep the battery about 60% capacity when not being used for longer periods of time. Remember if you treat your Bosch eBike Battery well it will treat you well in return. By following the tips above, your battery should last 8-10 years in the perfect conditions. It could last even longer.. Who knows?.. You are in charge now (Pun intended!) Find replacement Bosch / Yamaha Batteries & Battery Covers.
E-bikeshop is one of the largest Independent eBike dealers in the UK. We are keen to be able to give our customers the best after sales and customer care, so when Bosch contacted us to see if we would like a further training session on the new 2014 Bosch eBike system, we jumped at the chance! The day started off with an introduction to Bosch and their background, how Bosch eBike Systems have grown since 2012 and where they are now. I have to say in my mind Bosch are way ahead of the game now in the Crank Drive Electric Bike market. They have not only created a very good reliable eBike system, but Bosch are offering their full support to us (the UK dealer). This makes a real difference as it breaks down the barrier between dealer, manufacturer and supplier. It allows us to really understand the product and therefore give our customers the very best knowledge and support in-store for after sales care. This is of course one of our most important factors in any of our sales here at e-bikeshop. Any Bosch eBike enthusiasts heaven! The inside of every component. I take my hat off the Bosch guy’s that came over from Germany to show support here, the venue was very good, the presentation was well structured, Bosch presenters were very knowledgeable, and most importantly of all the food was fantastic with a steady flow of hot and cold drinks, lunch and coffee breaks in between.We went on to talk about how the Bosch eBike system has adapted over the last couple of years, how feedback has been taken on board and every aspect of the system has been improved as it adopts new user friendly features and functions. Bosch was not shy to talk about their competition in the presentation and did not seem phased by other manufacturers. They explained that they are a predominantly an automotive manufacturer, they have been able to move some of their knowledge from this market and use the components in the eBike design. Interestingly they didn't set out to dominate the market, but it naturally evolved very fast, they now provide to over 60 brands and manufacturers making Bosch one of the biggest eBike motor system suppliers in the world. Bosch were very clear that this growth had taken them by surprise and they quickly had to adopt a much larger support service, they quickly opted use already established bike distributors across Europe to give dealers quick access to parts and spares, alongside their own warranty and technical service. Bosch was very excited to present their new eBike system innovation for 2014. They outlined the many improvements that have been made for 2014. The introduction of the new Active and Performance line to run alongside their already established Classic+ line. Bosch were clear that the Classic+ line already used on thousands of electric bikes was not to be phased out by the new system but to run alongside it for the years ahead. The reason they introduced the new Active and Performance 2014 lines was to meet different eBiker's demand on the market. Both motors are the same drive units although they are tuned slightly different for rider’s needs. Both give more ground clearance and share the same new design. The difference between the normal Drive Pulley and the pedal back brake version. The differences lie in the programming, the Active line is described as 'Harmonious and Smooth', it gives a maximum 48Nm of torque, it offers a back pedal function (on particular bikes, mainly in Germany, not something we use much if at all over here in the UK). The Performance line is described as 'Dynamic and powerful', it gives a maximum of 60Nm torque and is tuned slightly more aggressive. Each system will feature on different bikes, for example the Active Line may feature on some more subtle touring and town bikes, whereas the Performance line will feature on more sporty MTB's and Road electric bikes.All of this info is just a brief overview of the changes for 2014, if you would like to ready how the Bosch eBike system works and performs I suggest you read a couple of my other blog articles. A view inside the new Bosch 2014 Drive Unit Motor Assembly. The new Bosch drive unit is designed with lots of improvements. Its optimized control technology employs 3 sensors to make 1000 measurements a second of the rider’s requirements. It’s actually got a more powerful 32-bit processor to handle all of these senses. It also incorporates gear shift detection where it will smooth gear changes by dropping the torque for just a second when you change gear. This will smooth out gear changes and also lower drivetrain wear. The new Bosch motor system also offers less vibration, its lighter, more compact and has a reduced crank width.The new smaller chain wheel innovation works by using and internal gearing ratio which turns the sprocket approximately 2.5 turns to every crank revolution. The chain wheel is significantly smaller, this is designed to lower torque per chain wheel cogs and thus lessen the wear on the drivetrain. It also is almost impossible for the chain to come off of rougher terrain. The Bosch Drive unit will come with 15, 18 or 20 teeth depending on the type of eBike.The new Bosch Intuvia on board computer has had improvements to the odometer, where the user can further fine adjust the wheel size so it matches up perfectly to your miles / speed when using other devices. The Intuvia has a new colour scheme, Platinum for the Active line and Anthracite for the Performance line; this matches all of the other components to quickly define the different Bosch systems. The walk function has also had some improvements to the speed it produces; it should now fit the rider a lot better. A view inside the Bosch battery itself, this is a textbook image, it would be too dangerous to transport an opened Lithium Cell in house. The Bosch PowerPack 300Wh & 400Wh batteries have also had some improvements to the on board BMS (Battery Management System) to make them more user friendly, you can now charge the battery on the eBike, which makes for much easier operation and has been requested for quite some time. Both 400 & 300Wh batteries are slightly smaller & lighter. They have a more compact design and are more appealing to the eye. Along with the battery the charger has had some minor improvements, including rubber feet so it doesn't slide off the bench (happens almost every day here). It’s slightly smaller and has no venting holes due to it being a more efficient and producing less heat. Charge times remain the same. The charger has a new plug which has a thumb print on top, so it should be easier to plug in without looking each time to see what way up the plug goes before plugging it in. We also covered all of the legal aspects involving electric bikes, proper maintenance and care of both the Batter and the Bosch eBike system, transportation of goods, installation of components & common faults and how to diagnose / resolve them. We here at e-bikeshop have most of this knowledge already. We have been working on Bosch powered eBike for a while now so have all the relevant tools, knowledge and diagnostics machines to perform these tasks. Our workshop mechanics are very competent in the use of these in setting up new eBikes as well as diagnosing faults on older ones. However, visiting Bosch was a good chance to brush up on these skills and also a good chance to see some more of the motor internals. Definitely a day well spent!
