Abstract
A method for operating a drive unit of an electric bicycle is disclosed. The method includes: determining a cadence of a crank drive of the electric bicycle, and operating the drive unit in a controlled manner to generate a drive power as a function of the determined cadence and on the basis of a power characteristics map of the drive unit. The power characteristics map includes a power characteristic curve which defines a predetermined relationship between the drive power of the drive unit and the current cadence, and the power characteristics map includes a maximum power range within which the power characteristic curve defines a maximum drive power of the drive unit. The maximum power range is within a cadence range that can be set by a rider of the electric bicycle.
