Transform a regular bicycle into an e-bike.

Friction drives like the Rubbee provide a lighter, simpler option for transforming a regular bicycle into an e-bike.

Velogical's all-new Velospeeder makes the friction drive even lighter. The compact e-drive solution weighs under 4 lb and allows for seamless switching between e-assist and manual riding. The company claims it's the lightest and smallest bicycle e-drive.
