Meet the Vektron

Ride it, Fold it, Go Further

The Vektron is a best-in-class electric bike that folds in 10 seconds to go on trains, in cars, and under desks. Shorten distances and flatten the hills on your commute, or put a couple of Vektrons in the trunk of your car on your next trip, so you can explore further.

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.

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.

One Size Fits Most

The Vektron has a low-step frame design and resizes in seconds—no tools required—to fit riders between 147 and 195 cm (4'10" – 6'5"),* so you can share the bike with anyone in your family.


* Vektron D7i and P9 only. The Vektron D8 fits riders between 160 and 195 cm (5'3" – 6'5").

Why the Vektron?

Tern Folding Technology

Product Reviews

The Tern Vektron is suitable for taking children and transporting groceries. Folded, it is as big as a long-distance suitcase and can be taken on the ICE train.


Tern designed the Vektron from the ground up as an e-bike, allowing it to avoid suffering from the flex or wobble that impacts other designs.

Business Insider

Crank this thing up to level five though, and you'll suddenly feel like Superman. It's incredibly satisfying when the motor kicks in (almost immediately). You can really feel the bike pulling forward; even big hills start to feel like a Sunday saunter in the park.


The Vektron can be quickly and easily shrunk to Hobbit size. The folding hinges and their closing levers are intelligently designed, the frame is rigid and very stable.



See for Yourself

We could go on and on about how the Vektron is a great bike. But nothing beats going for a test ride and finding out what’s the best match for you.
