Tern Vektron D8 2019 Bafang mid drive folding e-bike

  • Tern Bicycles has a wonderful reputation for top quality, innovative and long lasting folding bikes and this year they have released the first Tern electric folding bike. Using the same renowned platform, the Tern Vektron D8 model delivers the uncompromised performance of the Vektron family in an affordable package. What is unusual about this folding e-bike though is that it has a mid-drive system which offers the additional advantage of exceptional handling, range and smoothness.

  • You can fold the Tern Vektron D8 in seconds to carry it on the train or into a lift, and the compact folded size fits easily into car boots and smaller storage areas.  A fantastic inner-city transporter and great for travellers looking for high quality, longer-range folding ebikes with a mid-drive motor. 

  • Have a look at the Tern Vektron S10 if you want a Bosch-powered mid-drive folding ebike that is even more compact when folded, and that suits smaller riders.

A mid-drive folding e-bike of exceptional quality. 

The Tern Vektron is a best-in-class electric bike that folds in seconds if you want to go on trains, in cars, or store somewhere. With an electric drivetrain, 20” wheel bikes are just as fast as 700c. That means riders can enjoy all the benefits of small wheels—compact size, low centre of gravity, quick acceleration, manoeuvrable handling, and plenty of cargo space—with big wheel speed.  The Tern Vektron benefits from Tern's patented folding technology, OCL+ , which features a single-shaft design, advanced welding techniques, and robust gussets. This keeps the frame stiff and strong so it is not compromised by the folding, nor by carrying heavier loads and travelling at higher average speeds.  The Tern Vektron is also equipped with high quality components - Shimano hydraulic disc  brakes, Shimano 8-speed gearing, wider Schwalbe Smart Sam tyres for traction and puncture resistance, and its patented Andros stem. The stem is a no-tools adjustable stem and can easily be adjusted so its comfortable for all your family members. And, being Tern, there are some excellent additional accessories available such as the Tern cargo rear rack and carrying gear such as bags and baskets.

The Tern Vektron D8 is powered by the Bafang Max mid-drive system, a system that caused quite a stir when it was first released by winning the 24 Hr Endurance E-Bike Race at the Nurburgring in Germany. It is compact and  lightweight and with its 80Nm torque is impressively smooth and silent.  The Bafang Max motor is paired with a 418Wh lithium ion battery to provide approximately 40 - 90km of range. With the motor mounted at the crank and the battery positioned low down you, the rider, can enjoy excellent balance and handling. The controls are mounted on the handlebar which provides efficient, ergonomic thumb power shifting. You can choose from five levels of power and there is also a walk assist function.
