Product Description

All around the world, the way we get from A to B is changing. With the world on the cusp of auto-mobility, ride sharing, and the mainstream arrival of electric vehicles, it’s an exciting moment for transportation. To help drive this force of change, we developed the world’s most compact Bosch-driven electric bike. The Tern Vektron takes everything great about folding bikes—multi-modal commuting, portability for travel and storage—and accelerates it.

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.

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.
