Abstract
A bicycle control device controls a motor to assist driving of a wheel of a bicycle. The bicycle control device includes a controller configured to control the motor and an operation unit configured to be operated to switch operation modes of the motor. The controller includes at least a walk mode as the operation modes. In a case that a rotation speed of a wheel becomes lower than or equal to a predetermined value while the motor is driven in the walk mode, the controller is configured to control the motor so as to gradually decrease output of the motor and then stop driving the motor.
