Abstract
An electric drive device for a bicycle includes a transmission, an electric motor, a drive shaft, and a drive wheel arranged coaxially to the drive shaft. A first freewheeling element and a second freewheeling element are arranged in a one-piece freewheeling element carrier. The drive wheel is connectable to the drive shaft via the one-piece freewheeling element carrier by the first freewheeling element, and a rotary element of a planetary gear set of the transmission is connectable to the drive shaft via the one-piece freewheeling element carrier by the second freewheeling element. Another rotary element of the planetary gear set of the transmission is formed in one piece with a power transfer device.
