A detecting device is provided for detecting a condition of a bicycle crank assembly including a bicycle crank provided to a bicycle frame. The detecting device includes an electronic controller. The electronic controller is configured to obtain information relating to an image of the crank. The electronic controller is configured to determine an angle of the crank based on the information.

Detecting system

A control apparatus for a human-powered vehicle comprises a first controller. The first controller is configured to establish, in response to a user input, a wireless communication channel between a first wireless communicator of a first communication device and a second wireless communicator of a second communication device via a wired communication channel which is established between the first communication device and the second communication device through an electric cable and a first communication port configured to be connected to the electric cable.

Control apparatus, control system, and electric component for human-powered vehicle

To provide a circuit module, a bicycle electric component, and a communication system that are easily matched to a communication system that uses power line communication, a circuit module is configured to be mounted on a bicycle electric component. The circuit module includes a first circuit board, a communication converter configured to convert between information appropriate to power line communication and information appropriate to communication other than the power line communication and mounted on the first circuit board, and a plurality of first terminals formed on the first circuit board. The plurality of first terminals is connected to a second circuit board included in the electric component.

Circuit module, bicycle electric component, and communication system

A bicycle gear changing apparatus is basically provided with a controller that includes memory with a plurality of pre-stored shift tables. The controller is configured to control a shifting operation of at least one of a first gear changing device and a second gear changing device based on a selected one of the pre-stored shift tables.

Bicycle gear changing apparatus

A bicycle control apparatus is basically provided with a first gear changing device, a second gear changing device, a power supply sensor and a gear shift controller. The first gear changing device has a plurality of first shifting positions. The second gear changing device has a plurality of second shifting positions. The power supply sensor detects a power level of a power supply that is configured to supply power to at least one of the first and second gear changing device. The gear shift controller is programmed to cooperatively control the first and second gear changing devices, the gear shift controller being further programmed to individually control the first and second gear changing devices when the power level detected by the power supply sensor is lower than a first power level.

Bicycle gear changing control apparatus

A bicycle gear changing apparatus is basically provided with a controller including memory with a first prescribed shift route for upshifting and a second prescribed shift route for downshifting. The first prescribed shift route defines an order of actuation of at least one of a first gear changing device and a second gear changing device that is different from an order of actuation of at least one of the first and second gear changing devices that is defined by the second prescribed shift route. The controller controls a shifting operation of at least one of the first and second gear changing devices in response to a shift signal and in accordance with one of the first and second prescribed shift routes. The first prescribed shift route includes a least one user settable synchro-upshift point. The second prescribed shift route includes at least one user settable synchro-downshift point.

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.

Bicycle component control apparatus

A bicycle shifting control apparatus comprises a transmission controller configured to control a guide actuator of a derailleur to move a chain guide of the derailleur between a plurality of shift positions in response to an input shifting signal. The transmission controller is configured to control, in a shifting operation of the chain guide between adjacent two shift positions of the plurality of shift positions, the guide actuator to temporarily decelerate the chain guide at a deceleration position defined between the adjacent two shift positions so that the bicycle chain engages with and/or disengages from one of the sprockets having a shift assist structure prior to completion of the shifting operation of the chain guide.

Bicycle shifting control apparatus and method of controlling derailleur

A bicycle component control apparatus is basically provided with a communication interface and a controller. The communication interface is configured to communicate with at least one electric bicycle component and at least one manually operated input member. The controller is electrically coupled to the communication interface, and programmed to control the at least one electric bicycle component based on operation of the at least one manually operated input member. The controller is programmed to decide an operation mode of the at least one electric bicycle component differently based on a number of manually operated input member coupled to the controller via the communication interface.

A bicycle gear changing apparatus is basically provided with a controller. The controller is configured to be operatively coupled a first input to receive first shift signals. The controller is configured to be operatively coupled to a second input to receive sound shift signals. The controller outputs control signals to control at least one of a first gear changing device and a second gear changing device in accordance with a first prescribed shift route in response to receiving the first shift signals. The controller outputs control signals to control at least one of the first and second gear changing devices in accordance with a second prescribed shift route different from the first prescribed shift route in response to receiving the second shift signals.

A bicycle gear changing apparatus is basically provided with an upshifting input, a downshifting input and a controller. The controller is operatively coupled to the upshifting input and the downshifting input to receive upshift signals and downshift signals. The controller outputs control signals to control a first gear changing device and a second gear changing device in accordance with a synchro-downshift route and a synchro-upshift route that is different from the synchro-downshift route, in response to receiving the upshift signals and the downshift signals.

A rear derailleur is basically provided with a base member, a movable member, a chain guide, a friction element, a one-way clutch and an electric actuator. The base member is configured to be mounted to a bicycle. The movable member is movably coupled to the base member. The chain guide is coupled to the movable member to rotate around a rotational axis with respect to the movable member. The friction element is operatively arranged between the movable member and the chain guide to frictionally provide rotational resistance in a first rotational direction of the chain guide. The one-way clutch is operatively disposed between movable member and the chain guide to engage the friction element as the chain guide rotates in the first rotational direction. The electric actuator is operatively coupled to the one-way clutch to control the one-way clutch between a clutch-on mode and a clutch-off mode.
