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.
Best in Class
In test after test, the Vektron is called the best folding e-bike on the market. With an updated frame, upgraded Bosch motors, and a wide ecosystem of accessories to help you carry your stuff, the Vektron will easily turn a lot of your car trips into bike trips.
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.
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.
It rides like a dream and unlike just about any folding bike I’ve ever tried.
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 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.
School runs have never been more fun! The frame-integrated Atlas V Rack™ is designed to fit a Thule Yepp Maxi or a Dash® RM seat—no adapters needed.
