Abstract: A bicycle controller and a bicycle controlling method reduces a distance a bicycle travels before a motor is stopped regardless of whether pedaling is stopped in a state where a rotation speed of the crank is high. The bicycle controller includes an electronic control unit that controls a motor, which assists pedaling of a bicycle, based on a manual driving force and angle information related to an angle of a crank of the bicycle. If the crank is rotated by a predetermined angle or greater in a state where the manual driving force is less than or equal to a predetermined threshold value while the motor is driven, then the electronic control unit stops the motor.

Abstract: A bicycle control device controls a motor to assist driving of a wheel of a bicycle. The bicycle control device includes a sole first operation switch and a controller. The controller is configured to switch, when the first operation switch is operated, between a ride mode that controls the motor in correspondence with manual driving force and a walk mode that drives the motor in correspondence with the operation of the first operation switch. After switching to the walk mode in accordance with the operation of the first operation switch, the controller is configured to drive the motor in correspondence with the operation of the first operation switch.

Abstract: A bicycle transmission control device is basically provided with a transmission controller that is programmed to switch between a first control state and a second control state. The bicycle transmission control device operates in accordance with the first control state for controlling a transmission based on a first signal that is input from a first detector, which detects a rotation of a crank. The bicycle transmission control device operates in accordance with the second control state for controlling the transmission based on a second signal that is input from a second detector, which detects a value reflecting a bicycle 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.
