Gear assembly for a bicycle with an auxiliary drive

摘要

The transmission system (1) has a planetary gear which consists of multiple planetary wheels (2) and a planetary carrier (3). The planetary gear is designed to transmit a torque of an auxiliary drive of the bicycle on a pedaled drive unit (4) of the bicycle. A freewheel unit is provided by which the torque from the planetary gear is transferred to the drive unit. The freewheel unit has a tooth wheel (5) arranged on the planetary carrier and another tooth wheel (6) provided directly opposite to the former tooth wheel and arranged on the drive unit. An independent claim is also included for a bicycle with a frame.
