A bicycle driving device that allows a second motor to be reduced in size includes a first planetary mechanism, a first motor, a second motor, and a speed reduction mechanism. The first planetary mechanism includes a first input body to which rotation of a crank is input, a first output body that rotates when the first input body rotates, and a first transmission body that transmits rotation of the first input body to the first output body. The first motor is capable of rotating at least one of the first input body, the first output body, and the crank. The speed reduction mechanism reduces rotation produced by the second motor in speed and transmits the rotation to the first transmission body.
