Our Bosch Tuning (de-restriction) Kits remove the 15mph assistance cut-off on all Bosch powered eBikes.
The Bosch tuning kit we use differs by model year. Since 2018, we've exclusively been using Speedbox products. Prior to 2018, we used a different proprietary kit which can be unplugged by the user.
This covers the Bosch Active, Bosch Active Line, Bosch Cargo Line, Bosch Performance Line (Generation 3) and Bosch Performance Line CX (Generation 4) motors. It will NOT currently work with the new Bosch Smart System on some new 2022 models (read more below).
The Speedbox kit is activated/deactivated using the "WALK" button on the handlebar controls. Full instructions on the use of the currently supplied system can be found here. The unit is connected directly to the motor wiring and fitted inside the frame of the bike, normally inside the outer plastic motor housings.
This product is exclusively available to customers who purchase their bike(s) directly from E-Bikeshop. We do not supply, fit or ship this product for bikes purchased from other dealers.
PLEASE NOTE: UNLESS INSTRUCTED BY US PRIOR TO ORDERING, IF YOU PLACE AN ORDER FOR THIS PART AND IT'S NOT ACCOMPANIED BY A BOSCH DRIVEN BIKE IN THE SAME ORDER, THE ORDER WILL NOT BE FULFILLED AND YOU WILL RECEIVE A REFUND WITHIN 48 HOURS, MINUS AN ADMINISTRATION CHARGE.
Once installed, the tuning kit doubles the cut off speed of assistance. It can also be used with the Bosch S-Pedelec (Non-UK with 20mph cut-off) motors as it works in the same way. On early Bosch motors, the tuning kit can be easily unplugged whenever necessary to revert the bike back to normal. On Later Bosch systems (2018-on), the tuning kit is activated/deactivated using the "WALK" button on the handlebar control.
On earlier generation motors (pre-2017), the display will show an incorrect (halved) speed reading. Because the older generation system was less intelligent in the way it "fooled" the motor into thinking it was only going half as fast as it was, everything related to speed would be incorrect, including the miles covered.
On 2018-on Bosch systems, the new tuning kit doesn't have this small drawback, and will show the correct speed reading and log the correct number of miles covered.
This product will NOT work on the new Bosch Smart System equipped models featuring their larger 750Wh battery and Kiox 300 display. This is a compatibility issue between the current generation tuning kits, and the newly revised wiring, connectors and firmware on the new Bosch system. We expect that the tuning kit manufacturers will resolve this issue either before, or shortly after their release on the market and this notice will be removed when there is a solution available.
Please Note: We use references to "Bosch" only in the sense that this product is designed specifically to work with Bosch powered eBikes. This product is NOT manufactured, distributed or endorsed by Bosch themselves.
This product can be added to your basket when purchasing your new bike and will be fitted at no additional cost while we build it for you, however, please note that if you do not specify this part when new and choose to have it fitted during its first free service, routine/annual servicing or other maintenance/service/warranty related work, a small labour charge will apply.
Because this product is specifically designed to derestrict the motor and so increase the maximum assisted speed of Bosch driven ebikes to more than the 15.5mph UK limit, they are strictly FOR OFF ROAD (PRIVATE LAND) USE ONLY! They may not be used on the road, cycle paths, bridleways or anywhere else where the public have access.
Due to the continued development of software by the drive system manufacturers, tuning and de-restriction products are supplied on the basis that they may only work with the software version and motor components of the bike supplied at the time the tuning kit is supplied and no warranty or guarantee is given that these will continue to be compatible with future software versions or upgrades offered by the drive system manufacturer.
absolutely excellent it transforms your bike
Very good piece of kit. Transforms the bike. The dongle does need extra covering as it is prone to becoming loose and will cut out when wet. I tape the whole thing up in insulating tape. I expect there maybe issues in the winter and rides with deep wet mud etc.
So as you can see I shaved 4 minutes off my lap time. I also boosted my average speed from 12.5mph to 13.8mph This sort of performance over such a short distance has proved the dongle helps considerably!
Wow! Amazing! Great! Super! Yes!!!! (is the basic experience). Wow what a difference it makes - no longer are you just getting interested and the motor cuts out! Oh no! The thing just keeps going! F****** ace.
Just what I wanted. I don't know what else to say - I can only say that it is now exactly the bike I thought it could be. Only one other mod I did was to put a 45T chainring on it to deal with the higher top speed.
Otherwise I would say the bike is pretty much perfect.
