A control system for an electric bicycle includes an operating unit which is configured to control a ride controller of the electric bicycle. The operating unit is configured to allow a user to select among a plurality of assistance modes via an operating interface, and to control the ride controller in such a way that a drive control for a motor of the bicycle is carried out according to the selected assistance mode.

Control system for an electric bicycle

A device for controlling a motor of an electric bicycle. The device includes a control electronics system that is set up to control a torque of the motor in a normal operating mode based on an acquired driver torque; to detect during normal operation whether, at the current motor torque, no rotation of the motor is taking place even though a driver torque is being exerted, and to control the motor to continue to provide the motor torque in a blocking operating mode if it has been detected that at the present motor torque no rotation of the motor is taking place even though a driver torque is being exerted.

A method for changing a transmission ratio of an electrically controllable gearing of a bicycle, in particular of an electric bicycle, includes (i) measuring a pedaling frequency of the bicycle rider on the pedal shaft, (ii) measuring a pedaling force of the bicycle rider, and (iii) determining a gear change operating state on the basis of the measured pedaling frequency and on the basis of the measured pedaling force if the measured pedaling frequency is less than or equal to a lower frequency threshold value or is greater than or equal to an upper frequency threshold value, and/or the measured pedaling force is less than or equal to a lower force threshold value or is greater than or equal to an upper force threshold value. After determining the gear change operating state, a control signal is generated for the gearing according to the determined gear change operating state.
