Abstract:
A bicycle controller is provided that performs control in accordance with a riding condition of a bicycle. The bicycle controller includes an electronic control unit that controls a motor. The motor assists human power that is inputted to a bicycle. Upon determining a gear changer that changes a gear ratio of the bicycle is operated, the electronic control unit switches a control state of the motor from a first control state to a second control state based on a rotation phase of a crank of the bicycle and changes a timing at which the control state of the motor is switched from the first control state to the second control state based on an inclination of the bicycle in a front-rear direction.
