1. A control system for an electric bicycle, comprising:
an operating unit configured (i) to control a ride controller of the electric bicycle, (ii) to allow a user to select a selected assistance mode from a plurality of assistance modes via an operating interface, and (iii) to control the ride controller such that a drive control for a motor of the electric bicycle takes place in accordance with the selected assistance mode,
wherein the operating unit is further configured (i) to calculate a key figure for each assistance mode by way of a key figure calculation rule based on drive parameters stored for each respective assistance mode and to carry out a sorting of the assistance modes based on the key figures, or (ii) for each assistance mode, to provide the drive parameters stored for each respective assistance mode via an interface, to receive the key figures via the interface and to perform the sorting of the assistance modes based on the key figures received for the assistance modes,
wherein the key figures are calculated according to the key figure calculation rule from a maximum torque stored for each respective assistance mode and/or an assistance factor stored for each respective assistance mode,
wherein the maximum torque and/or the assistance factor are determined for a common operating point, and
wherein the common operating point is defined by one or more of a cadence, a rider's torque, and a speed.
