A control device of a gear transmission-equipped vehicle includes a power controller that starts power reduction control when it is determined that a start condition is satisfied, the power reduction control being control of reducing power transmitted from a driving source to a gear transmission. The start condition includes: a condition that a detection value of a gear position sensor that detects a current gear position of the gear transmission falls within a transition region between engagement regions corresponding to respective gear positions; and a condition that a speed difference obtained by subtracting a rotational speed of an output shaft of the gear transmission from a rotational speed of an input shaft of the gear transmission is a threshold or more.

An automatic bicycle shifter making use of a sheathed cable actuator utilizing a pulley arrangement to energize actuation cable thereof with high adaptability to single and double cable arrangement devices and provided with a gearbox employing a worm gearset for positive retention of actuated position and an encoder for accurate and programmable operation.

A highly adaptable user interface for gearing based bicycle power transmission devices powered by a linear servo actuator slaved to an electronic control system serving to automatically shift into desirable gearing ratios under user predefined 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. Ability to switch to manual mode augments rider total control of disclosed device.

A bicycle electric derailleur making use of a geared electrical motor with armature affixed to an electrical rotary encoder serving to provide derailleur position through direct sensing of position of actuating electrical motor.

A variable stem for a human-powered vehicle basically includes a head tube mount, a handlebar mount, a stem body, a positioning structure and a controller. The stem body couples the handlebar mount to the head tube mount. The stem body is configured to be moved between a first position and a second position. The handlebar mount is disposed at a different location with respect to the head tube mount with the stem body in the first position as compared to the stem body being in the second position. The positioning structure is configured to selectively position the stem body between a first position and a second position. The controller is configured to control the positioning structure while the human-powered vehicle is in a driving state.

A wheeled vehicle is disclosed. The wheel of the vehicle may be a powered wheeled vehicle with an engine and a transmission system. The transmission system may be used to select a gear ratio to a powered wheel of the wheeled vehicle, such as a single wheel.

There is provided a vehicle shift control device. A shift mechanism is configured to shift and transmit rotation of a crankshaft extending in a width direction of a vehicle to a driving wheel. A shift pedal is configured to receive a shifting operation for the shift mechanism. A shift detection mechanism is configured to detect a shift instructed via the shift pedal. A shift actuator is configured to perform a shift operation of the shift mechanism, in response to a detection content of the shift detection mechanism. The shift detection mechanism includes a detection unit configured to rotate in response to the shifting operation of the shift pedal and a sensor configured to detect rotation of the detection unit. A rotary shaft of the detection unit and a rotary shaft of the sensor are arranged at different positions, as seen from a side.

A controlling device according to the present disclosure includes a communication unit that receives setting information for setting an electric component of a human-powered vehicle to a predetermined setting, and a controller that sets the electric component to the predetermined setting, based on the setting information received by the communication unit. The controller determines whether or not a cancel condition for cancelling the predetermined setting is satisfied.

A bicycle operating device, having a center axis, comprises a mounting structure configured to be press fitted into a free end of a bicycle handlebar; and an operating structure for an operation of a bicycle component, the operating structure being coupled to the mounting structure.

A wheeled vehicle is disclosed. The wheel of the vehicle may be a powered wheeled vehicle with an engine and a transmission system. The transmission system may be used to select a gear ratio to a powered wheel of the wheeled vehicle, such as a single wheel.
