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