A control device is provided for controlling an adjusting device of a human-powered vehicle. The adjusting device adjusts a front initial sag amount of a front suspension of the human-powered vehicle in a state in where a rider is riding the human-powered vehicle and a rear initial sag amount of a rear suspension of the human-powered vehicle in a state where the rider is riding the human-powered vehicle. The control device comprises an electronic controller configured to output a front control signal that adjusts the front initial sag amount of the front suspension of the human-powered vehicle, and output a rear control signal that adjusts the rear initial sag amount of the rear suspension of the human-powered vehicle to the adjusting device based on traveling information related to traveling of the human-powered vehicle.

Suspension control device

A motor unit comprises a torque limiter and a transmitting structure. The torque limiter includes a first member and a second member. The first member and the second member are movable relative to each other in a state where a torque applied to the torque limiter is equal to or higher than a torque threshold. The first member and the second member are movable together with each other in a state where the torque is lower than the torque threshold. The transmitting structure includes a first race, a second race, a first intermediate element at least partially provided between the first race and the second race, and a second intermediate element at least partially provided between the first race and the second race.

Motor unit and derailleur

A control device including an electronic controller for controlling a human-powered vehicle. The electronic controller is configured to control an adjusting device that is configured to adjust a seat height of the human-powered vehicle upon determining the human-powered vehicle is being stopped while traveling uphill.

A shifting control device comprises a controller configured to control an actuator of a gear shifting device to arrange a chain guide of the gear shifting device on a plurality of gear positions. The controller is configured to control the actuator to temporarily arrange the chain guide on a first temporary position in a multistage gear shift operation before stopping the chain guide at the first target gear position. The controller is configured to temporarily arrange the chain guide on a second temporary position in a single gear shift operation before stopping the chain guide at the second target gear position. The first temporary position is offset from the second temporary position in the gear shift direction if the first target gear position is the first target gear position and the second target gear position correspond to the same gear position of the plurality of gear positions.

A bicycle-chain outer link plate comprises a first outer-link end portion, a second outer-link end portion, and a first outer-link intermediate portion. The first outer-link end portion comprises a first outer surface, a first inner surface, a first outer-link opening, and a first outer-link end outermost edge. The first outer-link intermediate portion comprises a first intermediate outer surface, a first intermediate inner surface, a first outer-link intermediate outermost edge, a first additional outer-link intermediate outermost edge, and a first intermediate chamfer. The first intermediate chamfer has a first minimum distance defined between the first outer-link intermediate outermost edge and the first inner edge along a reference line. A distance defined between the first outer-link intermediate outermost edge and the first additional outer-link intermediate outermost edge on the reference line is minimum in the first outer-link intermediate portion. The first minimum distance is equal to or larger than 1 mm.

An electrical bicycle derailleur includes a base member and a movable member movably arranged between a retracted position and an extended position. A linkage operatively couples the movable member to the base member. The linkage includes a first link member and a second link member. The first link member is disposed closer to the base member than the second link member. A motor unit is operatively coupled to the first and second link members to rotate the first and second link members. A linkage housing is configured to support the first and second link members and the motor unit. A first diameter of the first link member is different from a second diameter of the second link member and/or a first tooth number of the first link member is different from a second tooth number of the second link member.
