Abstract: A bicycle controller includes an electronic control unit controlling output of a motor that assists in propelling of a bicycle based on a manual driving force input to the bicycle. The electronic control unit further configured to control the motor in any one of operation modes including first, second and another operation modes, which control the output of the motor based on the manual driving force. The other operation mode excludes the first and second operation modes. In the first operation mode, the upper limit of output torque of the motor is a first value. In the second operation mode, the upper limit of output torque of the motor is a second value, which is 1.5 times or more than the first value. In the other operation mode, the upper limit of the output torque of the motor is the first value or less, or the second value or greater.

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.

Abstract: A bicycle controller controls a motor in accordance with the riding environment of a bicycle. The bicycle controller includes an electronic control unit that is configured to control a motor that assists in propulsion of a bicycle in accordance with a manual driving force. The electronic control unit is further configured to sets a response speed of the motor with respect to a change in the manual driving force for a case in which a vehicle speed of the bicycle is less than or equal to a first speed to be different from the response speed for a case in which the vehicle speed of the bicycle exceeds the first speed.

Abstract: A bicycle control device includes an electronic controller that controls a motor to assist propulsion of a bicycle. The electronic controller is configured to decrease an output of the motor upon determining that a shifting device is performing a shifting action to change a transmission ratio of the bicycle. The electronic controller is further configured to end the control that decreases the output of the motor before a predetermined period elapses upon determining that the shifting action is completed or the transmission ratio is changed before the predetermined period has elapsed. The electronic controller is further configured to end the control that decreases the output of the motor upon determining that the predetermined period has elapsed in a case where the shifting action or the change in the transmission ratio is uncompleted even though the predetermined period has elapsed.
