Abstract

A driving device for an electric vehicle includes a pedal shaft, first and second electric motors, an output shaft, and a superposition transmission whose gear ratio is steplessly adjustable by way of the electric motors. The transmission also couples the pedal shaft and the output shaft to each other. A torque generated by the first electric motor and/or the second electric motor can be at least partially transmitted to the output shaft. The driving device further includes an electronic anti-theft device used to lock the bicycle. When locked, at least one of the electric motors is operable to generate a torque that counteracts a rotation of the pedal shaft in a forward direction of rotation to inhibit theft of the bicycle.
