An electric drive device (1; 11; 21; 31) for a bicycle includes a transmission (4), an electric motor (5), a drive shaft (7; 7′), and a drive wheel (8) arranged coaxially to the drive shaft (7; 7′). A first freewheeling element (F1) and a second freewheeling element (F2) are arranged in a one-piece freewheeling element carrier (9). The drive wheel (8) is connectable to the drive shaft (7; 7′) via the one-piece freewheeling element carrier (9) by the first freewheeling element (F1), and a rotary element (12; SR, PT, HR) of a planetary gear set of the transmission (4) is connectable to the drive shaft (7; 7′) via the one-piece freewheeling element carrier (9) by the second freewheeling element (F2). Another rotary element (12; SR, PT, HR) of the planetary gear set of the transmission (4) is formed in one piece with a power transfer device (7; 7′; 9).
