To provide a shifting control device and an electric shifting system allowing a user to comfortably ride a human-powered vehicle, a shifting control device comprising a controller configured to control a shifting device in accordance with a first operation performed on an operating device for braking a rotary body of a human-powered vehicle.

An electronic device is configured to suitably control of a human-powered vehicle component. The electronic device includes a communicator configured to wirelessly communicate with a pressure detector detecting pressure of at least one tire of the human-powered vehicle. The electronic device is provided in a human-powered vehicle component including at least one of a transmission mounted to the human-powered vehicle, a suspension mounted to the human-powered vehicle, and an adjustable seatpost mounted to the human-powered vehicle.

A human-powered vehicle control device is configured to automatically control a suspension and an adjustable seatpost to a suitable state. The human-powered vehicle control device includes an electronic controller configured to control at least one of the suspension and the adjustable seatpost mounted to the human-powered vehicle upon detection of an inclined state of the human-powered vehicle based on a change in pressure of at least one tire of the human-powered vehicle. The pressure of the at least one tire is detected by a pressure detector configured to detect pressure of the at least one tire of the human-powered vehicle.

A human-powered vehicle control device is configured to control a derailleur in a suitable state. The human-powered vehicle control device includes an electronic controller configured to control a derailleur mounted to a human-powered vehicle based on a change in pressure of a tire detected by a pressure detector detecting the pressure of at least one tire of the human-powered vehicle.

A rear derailleur of a bicycle includes a fixing portion connected to a frame of the bicycle, a linkage assembly pivotally connected between the fixing portion and the moving portion, a moving portion pivotally connected to the linkage assembly, a chain guide assembly connected to the moving portion, and a driving assembly including a clutch assembly, a motor, and a driving gear assembly connected to the clutch assembly. The clutch assembly is disposed between the fixing portion and the linkage assembly and includes a first clutch member and a second clutch member. When a relative rotational torque between the first clutch member and the second clutch member is greater than a predetermined resistance, the first clutch teeth and the second clutch teeth shift relatively. Thereby, the driving gear assembly or the output shaft of the motor could be prevented from damaging.

Provided is a shifting device for shifting of a bicycle gear, such as a hub gear, of a bicycle. The shifting device includes a main control unit and preferably a motor control unit. The device includes a shifting control unit for receiving shifting instructions from the main control unit or the motor control unit. The shifting control unit includes a processing unit and a memory, power receiving means, such as including an electrical connector, for receiving power from a battery of the main control unit and/or a drive motor battery of the bicycle, a shifting motor, such as an electric motor, such as a stepper motor for providing a shifting motion for driving a shifting assembly for actuating a gear actuator, the shifting assembly for transferring the shifting motion from the shifting motor to the gear actuator, and the gear actuator for transferring the shifting motion to the bicycle gear. The shifting control unit, by means of communication with and controlling by the main control unit of the bicycle, is configured as a subsystem of the bicycle. The shifting control unit shifts the bicycle gear at each time on the basis of shifting instructions from the main control unit or the motor control unit.

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.
