Abstract

A pedelec includes a drive unit with a drive motor, a battery which supplies the drive motor with power, a control unit having a motor control unit and an assist function determiner, and an operating unit informationally connected to the control unit. The motor control unit controls the power based on a reference variable and an assist function. The assist function determiner defines the power based on the reference variable and selects the assist function. The assist function determiner comprises a standard assist function memory storing a standard assist function, and a standard zone memory storing an upper and lower zone boundary of a zone criteria for applying the standard assist function. An assist function selected by the assist function determiner provides more power below the lower zone boundary and less power above the upper zone boundary. The operating unit adjusts the upper and/or lower zone boundary.
