Skarper is a retrofittable e-bike drive system that can be integrated into the disc brake mechanism of an existing bike without tools. The system consists of a fully enclosed, wireless motor and the DiskDrive rotor. Once the rotor has been installed, the drive can be attached or removed with a click – without any modification to the frame or wheels. In this way, Skarper enables a quick switch between classic bike and e-bike.

Skarper is an incredibly easy way to retrofit traditional bicycles and thus expand the use of existing resources.
