Bike Rack
Electric Folding S2 Folds away. Carries more.
The Series 2 folder with a rear rack for everyday hauling — a 500W motor for 22–30 miles per charge, fat tires, and disc brakes that pack into your trunk.
The easiest way to get on a bike again
Three decades of refining one idea: a step-through frame that feels like an invitation, not an obstacle.
Pedal-assist that feels natural
The motor scales power to your effort, so hills flatten out and distance shrinks — without breaking a sweat.
Range for real rides
A high-capacity battery delivers dependable miles per charge, integrated cleanly into the frame for a balanced ride.
Equipped and ready
Integrated lights, fenders, and a rack come standard. Unbox, charge, and ride — nothing extra to buy.
