An electric pedelec bottom bracket drive includes a drive unit, a drive controller, and an ambient temperature detector. The drive unit includes a drive unit housing, a drive motor arranged therein, and a housing temperature sensor which measures a housing temperature. The drive controller supplies electrical drive energy to the drive motor and includes a housing temperature control module which is connected to the housing temperature sensor and which controls an electrical drive energy to not exceed a housing limit temperature. The ambient temperature detector is arranged to detect an air temperature outside of the drive unit housing and is connected to the housing temperature control module. The housing temperature control module limits a maximum electrical drive energy as a function of the air temperature when the housing temperature measured by the housing temperature sensor is above a control intervention limit temperature which is below the housing limit temperature.
