Tern Vektron D8 2019 - Electric Hybrid Bike
The Vektron is a best-in-class electric bike that folds in 10 seconds to go on trains, in cars, and under desks. 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 center of gravity, quick acceleration, maneuverable handling, and plenty of cargo space—with big wheel speed.
The Vektron D8 delivers the uncompromised performance, versatility and style of the Vektron family, in an affordable and convenient package. With hydraulic disc brakes, fenders and a rack, crush your commute rain, snow or shine.
Ready to Roll - Once you fold your Vektron, it’s easy to roll it around. The new frame design also lets you keep the bike in vertical position when folded, so stopping and going is easier than ever.
Rides Better - There are other folding electric bikes but none ride better. The Vektron is stiff and stable for a truly solid ride - even when fully loaded. Take a test ride and feel the difference.
Takes You Further - Take your Vektron on a train or bus to cover those extra-long commutes, or to complete the first and last leg of your commute faster. Ride to the station, hop on, hop off, and keep riding.
One Size Fits All - The Vektron has a low-step frame design and resizes in seconds—no tools required—to fit riders between 145 and 195 cm (4’10” – 6’5”), so you can share the bike with anyone in your family.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimeters for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but is like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the e mountain bike column.
