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 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.
