A system for a bicycle includes a plurality of controller devices. A type of controller device is the same for two or more controller devices of the plurality of controller devices. The system includes a pairing coordinator device configured to receive a respective device type identification from each controller device, and identify the type of controller device for the two or more controller devices based on the received device type identifications for the two or more controller devices. Based on the identification of the type of controller device, the pairing coordinator device is configured to update the device type identifications for the two or more controller devices, respectively, such that the updated device type identifications are different than each other. The pairing coordinator device is configured to pair only controller devices of the plurality of controller devices having different respective device type identifications with the pairing coordinator device.

A pneumatic-hydraulic control valve includes a valve base and a valve stem movably disposed in the valve base. A first inner oil guiding hole of the valve stem communicates with a first outer oil guiding hole of the valve base. A second inner oil guiding hole of the valve stem does not communicate with a second outer oil guiding hole of the valve base when the valve stem is closed, and communicates with the second outer oil guiding hole of the valve base when the valve stem is opened. Further, the valve stem has a first stressed portion for bearing a fluid closing force and a second stressed portion for bearing a fluid opening force. The outer diameter of the first stressed portion is larger than that of the second stressed portion. Thus, the present invention reduces a valve opening force without affecting the sealing effect.

A pneumatic-hydraulic type control valve includes a cable attached to a fixed base, a valve base disposed in the fixed base, and a valve stem disposed in the valve base and driven by the cable to be opened. First and second oil guiding holes of the valve base communicate with each other when the valve stem is opened, and the first and second oil guiding holes of the valve base do not communicate with each other when the valve stem is closed. Further, the valve stem has a first stressed portion for bearing a fluid closing force and a second stressed portion for bearing a fluid opening force. The outer diameter of the first stressed portion is larger than that of the second stressed portion. Thus, the present invention achieves effects of simplifying structure and accurate actuation without affecting the sealing effect.

An operating device for a height-adjustable seatpost tube including a lifting magnet. The lifting magnet has a magnetic core surrounded by a coil. The magnetic core cooperates with an actuating device of a lifting device, the lifting device being a pneumatic lifting device for height-adjustment of the seatpost tube and thus for heigh-adjustment of the seat, for example.

An electrical device for a system of a human-powered vehicle comprises a controller. The controller is configured to selectively act, based on reference information relating to the system, as each of a master controller and a slave controller. The master controller is configured to transmit a first control signal to a different slave controller of a different electrical device of the system. The different slave controller is configured to be operated in response to the first control signal. The slave controller is configured to be operated in response to a second control signal transmitted from a different master controller of a different electrical device of the system.

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 dropper post assembly for supporting a bicycle seat can include an outer tube and an inner tube telescopically receivable in the outer tube and slidable within the outer tube between a retracted position in which a lower end of the inner tube is proximate a lower end of the outer tube and an extended position in which the lower end of the inner tube is axially spaced from the lower end of the outer tube. An actuator assembly may include an actuator body having a mounting portion connected to the lower end of the outer tube and a cartridge rod receiving portion, and may be configured so that when the inner tube is in the retracted position at least the upper surface of the cartridge rod receiving portion is nested within the inner tube.

A human-powered vehicle component includes an input device, to which first information related to at least one of a human-powered vehicle, a rider of the human-powered vehicle, and environment of the human-powered vehicle is input. The human-powered vehicle component further comprises an electric actuator and an artificial intelligence processor configured to generate second information for controlling the electric actuator in accordance with the first information input to the input device.
