A wireless communication method adapted to an electrical gear-shifting system of bicycle comprises: establishing a first communication connection to an intermediate device by a master controller; establishing a second communication connection to the intermediate device by a slave controller, sending a control signal to the intermediate device through the first communication connection by the master controller, sending the control signal to the slave controller through the second communication connection by the intermediate device, wherein the slave controller controls a motor driver to perform a gear-shifting operation according to the control signal.

A shifting system for a human-powered vehicle comprises a controller. The controller is configured to receive a driving torque and a cadence of the human-powered vehicle from at least one sensor. The controller is configured to determine a permitted shift timing based on the driving torque and the cadence. The controller is further configured to control a shift mechanism to perform a gear shift during the permitted shift timing.

A bicycle control system comprises a first electrical component and a second electrical component. The first electrical component comprises a first base member, a first movable member, a first actuator, and a first controller. The first movable member is movable relative to the first base member. The first actuator is configured to move the first movable member relative to the first base member. The first controller is configured to control the first actuator. The second electrical component comprises a second base member, a second movable member, a second actuator, and a second controller. The second movable member is movable relative to the second base member. The second actuator is configured to move the second movable member relative to the second base member. The second controller is configured to control the second actuator. The first controller and the second controller are configured to wirelessly communicate.

A shifting operation detecting apparatus includes a gearbox and a shift change apparatus. The shift change apparatus includes a shifting operation unit, a shifting operation receiving section, a swing lever and a connecting member. A shift operation detector is disposed between the swing lever in an outer shaft section of the shifting operation receiving section and a gearbox case to directly detect a pivoted state of the shifting operation receiving section, and the connecting member is connected to the swing lever from the gearbox case side.

There is provided a motorcycle. A crankshaft extends in a width direction of the motorcycle. An engine case pivotally supports the crankshaft. A counter shaft is arranged in parallel with the crankshaft. A clutch mechanism is arranged at one end of the counter shaft and configured to transmit and disconnect rotation of the crankshaft to and from the counter shaft. A clutch actuator performs a disconnection/connection operation of the clutch mechanism. A shift mechanism is arranged below the counter shaft and configured to shift and transmit the rotation of the crankshaft to a driving wheel. A shift actuator performs a shift operation of the shift mechanism. A generator is arranged at one end of the crankshaft. The clutch actuator and the shift actuator are arranged around a cover member mounted to the engine case and accommodating therein the clutch mechanism or the generator.

A bicycle electric derailleur making use of a geared electrical motor located on the predominantly stationary portion of said derailleur assembly thereby alleviating extraneous loads to actuating apparatus due to inherent shocks and vibrations, and additionally offering suitability for implementation in an automatic electronic control system as well as simpler manual apparatuses through reliance on a variety of versatile derailleur position resolving means for superior adaptability.

The invention relates to a bicycle including a frame (2) with a fork, the fork having dropouts (4) between which a wheel axle (1) is mounted. The wheel axle (1) includes a sensor and/or an electric component (16) arranged to be connected to a control element (29). A detachable electric connection is provided between the sensor and/or electric component (16) and the control element (29). The detachable electric connection includes a short range wireless connection.

A bicycle control device for issuing at least one command to at least one bicycle equipment comprises a body configured to be mounted on the bicycle, at least one manual actuation member associated with the body, and a clicking mechanism. The clicking mechanism comprises a magnetic clicking switch having a first element that is fixed with respect to the body, and a second element that is movable with respect to the first element and actuatable by said at least one manual actuation member when said manual actuation member issues said command.

The invention relates to a bicycle including a frame with a fork, the fork having dropouts between which a wheel axle is mounted. The wheel axle includes a sensor and/or an electric component arranged to be connected to a control element. A detachable electric connection is provided between the sensor and/or electric component and the control element. The detachable electric connection is positioned between the wheel axle and the thru-axle.

An electromechanical control system for a bicycle has a switch device, the switch device operating a switch between at least three positions. A control communication device transmits signals responsive to operation of the switch. The electromechanical control system includes an operation device configured to respond to signals transmitted by the control communication device. Signals transmitted by the control communication device include commands to listen and commands to operate.
