Most electric bicycles on the market are heavy & difficult to carry around. But the Vektron from Tern and Bosch is a new kind of e-bike: light, compact, and able to fold up small enough to fit in a car trunk. - inhabitat
The new Tern Vektron S10 could be the most versatile Bosch eBike on the market. Looking for portability & a efficient German assisted eBike? The Tern Vektron S10 does just that.
The Vektron S10 offers a unique approach to frame design. With a telescopic seat post and adjustable angle stem, it can accommodate riders from 4ft 10 to 6ft 5. A bike that suits all.
Although compact the wheel base is that of a regular bicycle, the handlebar, fork and overall geometry give for a nice smooth and comfortable ride whilst maintaining the practicalities of being able to pack this electric bike away.
Couple the above with well spec'd components, it brings an overall great bike for a mixture of uses & riding styles.
Tern is well know for their reputable folding bikes. Now for the first time ever they join forces with German manufacturer- Bosch. Bringing a unique approach to the modern rider. As you pedal the system assists and responds to the terrain and hills as you ride.
Be it under the desk at work, on and off the train or stow away in the back of your car or motor home. The Tern Vektron S10 offers up as a fully versatile and portable electric bike.
In 3 simple steps - The handlebars fold down, the frame folds in half and the seat can be retracted to fit this electric bike into even the smallest of places with ease.
The Tern folds from a complete bike down to folded format in under 10 seconds. This is due to the patented folding mechanism, which naturally folds as you release the catches.
No magic involved, just excellent design!
Notice how little space it takes up with wise. This is because of it's excellent folding and that the off side pedal removes, shortening overall width further.
The additional space means that the Tern Vektron can be fitted with a Child seat and is fully compatible with Thules Yepp Maxi or Nexxt Maxi child seats.
This combined with Klickfix compatibility makes the Vektron equally at home on the school run, work commute or even the food shop.
Much like the GSD, the rack also doubles as a storage option, allowing for the bike to be stood up on its end when folded to further lessen the bikes footprint when not in use.
The Tern Vektron S10 offers all those rider essentials including a comfort gel saddle, adjustable handlebars, comfort grips and adjustable seat post.
On top of this, the Vektron comes fully equipped with mudguards, pannier rack & side stand.
Tern have developed a fully built in LED lighting system front and rear. Completely powered off the Bosch system, itself. No bulbs, no batteries & they cannot be pinched off the bike.
We see Magura hydraulic disc brakes front and rear, allowing a use friendly, low maintenance experience whilst having the true braking power disc brakes bring.
The front chain ring and chain is covered by Tern's unique chain guard, keeping you, the rider, clean in all conditions. As both the Bosch motor and battery are mounted in the centre of the bike, it makes for an even weight distribution between the wheels whilst keeping the centre of gravity low, for a nimble and responsive ride.
Gearing on the Tern is provided by Shimano's Deore 10 speed drive train, for simple shifting both up and down hill.
Operated using a dual action trigger shifter on the handlebars and shadow rear mech that keeps the chain taught even over bumpier terrain.
The alloy double wall rims offer a strong and lightweight solution for smaller 20" wheels. Laced onto Shimano quick release hubs, making wheel removal a breeze.
The Tern Vektron is grips with decent Schwalbe Big Apple tyres which are designed for maximum grip whilst keeping rolling resistance to a low. More importantly they include the kevlar lining protection to prevent annoying punctures.
The Big Apple's are also designed to absorb the riding surface, giving a more comfortable overall feel for the rider.
All in all, the new Tern Vektron electric folding bike ticks the boxes for those looking for a nice ride and neat solution to travel and storage. A nice simple, but good quality electric bike, suitable for a mixture of riding styles and rider heights.
The new Tern Vektron S10 features the latest Bosch Active Line Plus eBike system. Offering a larger sprocket upfront with no internal gearing, this motor is much quieter and features little resistance when pedalling outside of the assistance.
The system is designed to be smooth and is around 30% more compact than the previous Active line. Offering support up to 270% and peak torque levels of 50Nm this system offers smooth and punchier power delivery both around town and on longer rides alike.
For 2019 Tern have equipped the Bosch Purion display, a revised smaller dash that offers quick vision of essential parameters whilst occupying a minimal amount of cockpit space.
The Tern Vektron S10 comes with a bigger 400Wh battery for 2019, offering a full day in the saddle with no battery range anxiety. Support is delivered in 4 different assistance modes up to 15mph.
