摘要： A method and device for operating an electric bicycle that has an electric motor and a transmission with at least two gears is provided. The method includes ascertaining a current pedal frequency that is generated by a user of the electric bicycle and checking whether the ascertained current pedal frequency lies within a specified pedal frequency interval. The method also includes ascertaining a current travel speed of the electric bicycle, ascertaining at least two transmission gears within the specified pedal frequency interval depending on the ascertained travel speed, and ascertaining a respective output of the electric motor for each of the ascertained at least two gears. The method also includes ascertaining the lowest ascertained output of the electric motor by comparing the two ascertained outputs of the electric motor, and ascertaining the transmission gear for which the lowest output was ascertained.
