Abstract: A bicycle control device that easily maintains the ratio of the assist force generated by a motor to the human drive force input to a bicycle at a predetermined ratio includes an electronic controller that controls a transmission, which is configured to change the transmission ratio of the bicycle, and the motor, which assists propulsion of the bicycle. The electronic controller is configured to control the motor so that the ratio of the assist force generated by the motor to the human drive force inputted to the bicycle becomes equal to the predetermined ratio. The electronic controller is configured to control the transmission in correspondence with at least one of the output torque of the motor and the human drive force to maintain the predetermined ratio.

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 set a response speed of the motor with respect to a change in the manual driving force input to the bicycle for a case within a predetermined period from a time at which the bicycle starts to travel to be different from the response speed for a case in which the predetermined period has elapsed.

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 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.

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.
