A bicycle controller limits decreases in the assist force when the rotational speed of a crank changes. The bicycle controller can be mounted on a bicycle including a first transmission having at least two shift stages and configured to change a ratio of rotation of a wheel to rotation of a crank, a motor that provides assistance to human power input to the crank, and a second transmission configured to transmit a rotation force from the motor to a power transmission path extending from the crank to the wheel without changing the ratio of the rotation of the wheel to the rotation of the crank. The bicycle controller includes an electronic control unit that controls the second transmission in accordance with a condition of the bicycle and either one of a condition of the first transmission and a shift instruction to the first transmission.

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.
