Meet The Vektron
Ride it, Fold it, Go Further
The Vektron is a top-tier folding e-bike that packs down in 10 seconds, allowing it to fit on trains, in cars, or under desks. Tackle hills, shorten commutes, or take two along on your next trip to ride further.
Best in Class
The Vektron is often rated as the best folding e-bike, featuring an upgraded Bosch motor, an updated frame, and smart accessories to carry your gear—making it easy to swap car trips for bike trips.
Ready to Roll
Fold the Vektron and simply roll it along. Its new frame design lets it stand upright when folded, making stops and starts effortless.
Rides Better
Other folding e-bikes exist, but none ride like the Vektron. Stiff, stable, and solid—even when loaded. Take a test ride and feel the difference.
Takes You Further

One Size Fits Most
