A drive device (5) for an electric bicycle (1) has a motor unit (6) with an electric motor for driving the electric bicycle (1). The drive device (5) also has a pedal crankshaft (11, 12) which can be rotated about an axis of rotation (R). Furthermore, the drive device (5) has a transmission (15), which is designed to drive the electric bicycle (1) and is coupled on one side to the motor unit (6) and on the other side to the pedal crankshafts (11, 12), and which is designed to output a torque for driving the electric bicycle (1). The drive device (5) further comprises a motor housing (7) in which the motor unit (6) and the transmission (15) are arranged and through which the pedal crankshafts (11, 12) extend. Furthermore, a rotational speed sensor unit (10) is provided which comprises a rotational speed sensor (9) and a rotational speed disk (8), the rotational speed disk (8) being coupled to the pedal crankshafts (11, 12) so as to be rotatable about an axis of rotation (R) and being arranged outside the motor housing (7).
