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 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.

A remote control unit for a display unit of an electric bicycle, the remote control unit being situated in the region of a handlebar grip remote from display unit and having assistance selection keys for the selection of the assistance level and having at least one input device for the menu navigation and selection of menu items shown on display unit. Input unit and assistance selection keys together are situated along a common line. Furthermore disclosed is an electric bicycle including such a remote control unit.

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.

A display unit for an electric bicycle, the display unit being fastenable to a handlebar of bicycle with the aid of a holding assembly. A display unit is mountable with the aid of holding assembly optionally in a first mounting position closer to the rider or in a second mounting position further away from the rider. Furthermore disclosed is an electric bicycle having such a display unit.

A bicycle gear shift operating apparatus is provided which can easily stop a gear shift operating lever at a gear shift position without replacing all constituent parts of a component. A gear shift operating apparatus 100 is an apparatus that is coupled to a rear derailleur 70 of a bicycle via a shift cable 60. The gear shift operating apparatus 100 includes a gear shift operating lever unit 40, an operating shaft 1 that rotates by operation of the gear shift operating lever unit 40 and pulls and releases the shift cable 60, and a replaceable gear shift position notification unit 10. Rotation stop positions corresponding respectively to gear shift positions of the rear derailleur 70 that are switched in accordance with the rotation of the operating shaft 1 are set in the gear shift position notification unit 10.

An automatic bicycle drivetrain shifting apparatus comprising a bicycle drive chain derailleur powered by a servo gearmotor slaved to an electronic control system and controlled through a highly adaptable user interface serving to automatically alternate drive chain position between available bicycle drive sprockets under user defined shifting criteria adaptable in real time to rider conditioning, comfort level and road conditions thereby alleviating manual shifting tasks and achieving optimal pedal rate and effort settings for the rider.
