摘要

The bicycle (1) comprises an auxiliary motor (5), which is a hub motor, a drive wheel (2) drivable by the auxiliary motor, a pedal set (8) with a bottom bracket (81) and a generator (6) connected with the pedal set, such that the mechanical energy produced by the pedal set is converted into electric energy. The auxiliary motor of the drive wheel is arranged mechanically separated from the pedal set, such that the auxiliary motor is operable by the electric energy provided by the generator or by an energy storage (4), where the generator is arranged in the bottom bracket of the pedal set. An independent claim is included for a method for operating a bicycle with an auxiliary motor.
