A bicycle derailleur comprises a unit mounting portion, a battery mounting portion, a wireless communicator, an electrical connector, and a battery. The wireless communicator is detachably disposed at the unit mounting portion. The electrical connector receiving portion is configured to receive a connector. The battery is configured to be disposed at the battery mounting portion.

Bicycle derailleur

A bicycle derailleur comprises a unit mounting portion, a wireless communicator, an electrical connector receiving portion, and a power supply portion. The wireless communicator is disposed at the unit mounting portion. The electrical connector receiving portion is configured to receive a connector. The power supply portion is configured to receive electricity from a battery disposed at a location apart from the bicycle derailleur.

A human-powered vehicle control device includes: an input rotary body to which a human driving force is input; a driving wheel driven by rotating the input rotary body; a transmission configured to change a ratio of a rotational speed of the driving wheel to a rotational speed of the input rotary body; a motor that assists in propulsion of the human-powered vehicle; and an electronic controller configured to control the motor. The electronic controller controls the motor in accordance with the human driving force in a case where one of the rotational speed ratio and a transmission stage of the transmission is in a first state, and stops the control of the motor in accordance with the human driving force in a case where one of the rotational speed ratio and the transmission stage is in a second state different from the first state.

Human-powered vehicle control device

A bicycle drive unit includes a motor that assists propulsion of a bicycle and a wire operation device that operates a wire, which is connectable to a bicycle component.

Bicycle drive unit and bicycle drive system including bicycle drive unit

A bicycle transmission is provided that includes a transmission, a connecting portion, a cable and a detection device. The connecting portion is connected to the transmission. The cable is coupled to the connecting portion to operate the transmission. The detection device is arranged to detect movement of the connecting portion.

Bicycle shifter, bicycle transmission device, and bicycle electric system

A bicycle control apparatus is provided that can improve the stability of the behavior of a bicycle. The bicycle control apparatus includes a controller that is configured to reduce the output of a motor when a rear wheel of a bicycle is in a prescribed state. The prescribed state is a state in which a load of the rear wheel is determined to be less than a prescribed load for a duration of time that is equal to or more than a prescribed time.

Bicycle control apparatus and bicycle driving device equipped with a control apparatus

A bicycle control apparatus is provided that can improve the stability of the behavior of a bicycle. The bicycle control apparatus includes a controller configured to control a motor that assists a manual drive force, based on a state of a suspension that absorbs vibrations of a bicycle.

A human-powered vehicle control device is configured to reduce electric power needed to drive a motor. The human-powered vehicle control device includes an electronic controller and a memory. The electronic controller is configured to control a motor that assists in propulsion of a human-powered vehicle in accordance with human driving force and a memory. The electronic controller drives the motor in a case where the human driving force is greater than or equal to a first value. The memory electronic changeably store the first value.

A bicycle suspension control apparatus includes a user operating device and a controller. The controller is operatively coupled to the user operating device to selectively control a pair of bicycle suspensions between a plurality of operating states. The controller selectively changes the operating states of both of the suspensions to different ones of the operating states in response to a single operation of the user operating device. The controller includes a receiving part, a storage part and a control part. The receiving part receives combination information indicating at least one combination of the operating states from among combinations of the operating states of the suspensions. The storage part stores the combination information received by the receiving part. The control part controls the suspensions based on the combination information stored in the storage part when the user operating device is operated.

Bicycle suspension control apparatus

A bicycle component control apparatus is basically provided with a power supply sensor and a controller. The power supply sensor detects a power level of a power supply being supplied from the power supply to two electrical bicycle components. The controller operates the two electrical bicycle components in response to receiving at least one signal from at least one input member. The controller operates the two electrical bicycle components at different starting times while the power level is below a prescribed power level. The controller is configured to simultaneously operate the two electrical bicycle components while the power level is above the prescribed power level.

Bicycle component control apparatus

A bicycle control apparatus is provided that can improve the stability of the behavior of a bicycle. The bicycle control apparatus includes a controller configured to reduces an output of a motor that assists a manual drive force, upon determining a pitch angle of a bicycle body becomes greater than or equal to a prescribed angle, or based on a state of a suspension that absorbs vibrations of a bicycle, or upon determining a load that is applied to a rear wheel of a bicycle becomes less than a prescribed load.

A bicycle shifter is provided as part of a bicycle electric system. The bicycle shifter basically includes a transmission cable winding element, an operating unit and a detection device. The operating unit operatively coupled to the transmission cable winding element. The detection device is arranged to detect a movement of the operating unit. The detection device outputs a signal according to the movement of the operating unit with respect to the winding element.

A bicycle component control apparatus is basically provided with a controller that is configured to operate a first electrical bicycle component in response to receiving a first signal from a first input member, and to operate a second electrical bicycle component in response to receiving a second signal from a second input member. The controller is configured to prohibit operation of the second electrical bicycle component upon starting operation of the first electrical bicycle component.

A bicycle transmission control apparatus comprises a control unit that provides a first signal to operate a first derailleur a gear shift distance from a first origin sprocket to a first destination sprocket. The control unit receives a condition signal that indicates a condition resulting from at least one of the first derailleur and a second derailleur; and an adjustment controller moves the first derailleur an adjustment distance less than the gear shift distance in response to the condition signal.

Apparatus for adjusting a position of a bicycle derailleur

A bicycle component controlling includes at least a first sensor and a controller. The first sensor detects a first operating condition, whether a rider is sitting on a bicycle seat. A second sensor is provided that detects a second operating condition. The sensors output signals indicative of the respective operating conditions. The controller is operatively connected to at least the first sensor and possibly the second sensor. The controller is configured to generate a component control command to control a bicycle component based on at least the first signal and the possibly the second signal. The bicycle component is a component other than an automatic transmission and a suspension when the second sensor is not provided. If the second sensor is provided, a suspension and automatic transmission is controlled, or components other than an automatic transmission and a suspension is controlled.
