In an embodiment a drive device includes a motor unit with an electric motor configured to drive an electric bicycle, a hub axle coupled to the electric motor, a gearbox, which is configured to drive the electric bicycle and is rotatable about an axis of rotation, and which is coupled to the electric motor and to the hub axle and is configured to output a torque for driving the electric bicycle, and a motor housing, in which the electric motor and the gearbox are arranged and through which the hub axle extends, the electric motor being shielded by an adjacent wall of the motor housing, which extends into an outer region outside the motor housing so that heat generated by the electric motor during operation of the electric bicycle is dissipated to the outer region by direct heat conduction through the wall.
