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 first transmission stage (10) and a second transmission stage (20), which are designed to drive the electric bicycle (1). The first transmission stage (10) is coupled to the motor unit (6) on the one hand and to the second transmission stage (20) on the other hand. The second transmission stage (20) is also provided for transmitting a torque for driving the electric bicycle (1). The second transmission stage (20) is designed as a shaft transmission and can be arranged coaxially with respect to a rotational axis (8) of a pedal crank (4) of the electric bicycle.
