Abstract

A method for automatically controlling the gear of a gearshift of an electric bicycle. At least one actual operating parameter of a drive component of the electric bicycle is recorded by recording an operating variable of the drive component. The at least one actual operating parameter is compared to a setpoint default, which reflects an operating point of the electric drive, which is linked to a higher efficiency, a greater reliability or a greater durability of components of the electric drive or of the drive component than in response to an operation according to the at least one actual operating parameter. The at least one actual operating parameter is approximated to the setpoint default by changing the gear. A corresponding device for automatically controlling the gear is also described.
