Abstract: A human-powered vehicle control device includes an electronic controller configured to control a motor to drive a transmission body with the motor and operate the transmission body with a derailleur to perform a shifting action that changes the transmission ratio in a case where a crank axle is stopped. The electronic controller includes a first control state in which the shifting action is performed and a second control state in which a driving force of the motor during the shifting action is reduced compared to the first control state. The electronic controller shifts the control state to the second control state in a case where a rider is riding the human-powered vehicle and the human-powered vehicle is stopped. The electronic controller shifts the control state from the second control state to the first control state in a case where a predetermined condition is satisfied.

Abstract: A human-powered vehicle includes a crank axle, a first rotational body, a wheel, a second rotational body, a transmission body that transmits a driving force between the first rotational body and the second rotational body, a derailleur configured to operate the transmission body to change a transmission ratio, and a motor configured to drive the transmission body. A control device has an electronic controller configured to control the motor and drive the transmission body with the motor upon determining the derailleur has been actuated to change the transmission ratio and a predetermined condition related to pedaling is satisfied, and control the motor to increase a rotational speed of the motor as a difference of a first rotational speed, which is calculated in correspondence with a rotational speed of the wheel and the transmission ratio, and a predetermined rotational speed or a rotational speed in a predetermined range increases.

Abstract: A bicycle component controller is basically provided with a processor. The processor is configured to perform a gear shift control based on a sprocket assembly information of at least one sprocket assembly. The sprocket assembly information at least includes a single shifting distance and shifting gate information. The single shifting distance corresponds to an axial spacing between adjacent sprockets of the at least one sprocket assembly.
