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 human-powered vehicle control device includes an electronic controller that is configured to control a motor that assists in propulsion of a human-powered vehicle and that stops assisting in the propulsion of the human-powered vehicle at a timing suitable for a state of the human-powered vehicle or a state of a road. The electronic controller drives the motor in correspondence with a human drive force upon determining a traveling speed of the human-powered vehicle is less than a predetermined speed that is higher than 0 km/h. The electronic controller varies the predetermined speed in correspondence with at least one of a state of the human-powered vehicle and a state of a road on which the human-powered vehicle travels. The electronic controller does not assist the propulsion of the human-powered vehicle upon determining the traveling speed of the human-powered vehicle is greater than or equal to the predetermined speed.
