Abstract: A bicycle component controller is basically provided with a processor. The processor is configured to perform a gear shift control based on a sprocket assembly information of at least one sprocket assembly. The sprocket assembly information at least includes a single shifting distance and shifting gate information. The single shifting distance corresponds to an axial spacing between adjacent sprockets of the at least one sprocket assembly.

Abstract: 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.

Abstract: A bicycle derailleur includes a base member, a movable member, a link member, a chain guide, a biasing mechanism and a switching member. The link member movably couples the movable member to the base member. The chain guide is pivotally coupled to the movable member about a pivot axis. The biasing mechanism is operatively disposed between the movable member and the chain guide, and biases the chain guide with respect to the movable member about the pivot axis in a first direction in a biasing state. The switching member is configured to selectively switch the biasing mechanism between the biasing state and a releasing state. The biasing mechanism biases the chain guide less in the releasing state than the biasing state. The switching member is disengaged from the biasing mechanism in the biasing state. The switching member is engaged with the biasing mechanism in the releasing state.

Abstract: A rear derailleur includes a base member, a movable member, a linkage and an electric motor unit. The base member includes a bicycle mounting portion for attaching to a bicycle. The movable member includes a chain guide having a first pulley that rotates around a first pulley axis in a center pulley plane that bisects the first pulley. The linkage movably supports the movable member relative to the base member. The electric motor unit is stationary with respect to at least a part of the base member and operatively coupled to the linkage to move the movable member relative to the base member between an outermost lateral position and an innermost lateral position. The electric motor unit is at least partially disposed inward of the center pulley plane while the movable member is disposed in the outermost lateral position.

Abstract: A bicycle motor unit comprises an electric motor and a transmitting structure. The electric motor is configured to generate a driving force. The transmitting structure is coupled to the electric motor to transmit the driving force from the electric motor to an actuated device of a bicycle. The transmitting structure includes a first rotatable member, a second rotatable member, and a resisting structure. The first rotatable member is rotatable about a rotational axis. The second rotatable member is rotatable relative to the first rotatable member about the rotational axis. The resisting structure is at least partially provided radially between the first rotatable member and the second rotatable member with respect to the rotational axis so as to resist relative rotation between the first rotatable member and the second rotatable member.

Abstract: A component for a human-powered vehicle basically comprises a power source connecting portion, an actuator and a first electronic controller circuitry. The power source connecting portion is connected to a power source. The power source connecting portion includes an attachment surface, a first terminal and a first detection terminal. The actuator is electrically connected to the power source connecting portion. The first electronic controller circuitry controls the actuator with supply current provided from the power source. The first terminal is electrically connected to a power supply terminal of the power source. The first terminal supplies the supply current to the actuator in a state where the first detection terminal is electrically connected to a second detection terminal of the power source. The first detection terminal contacts to the second detection terminal after the first terminal contacts to the power supply terminal during connecting operation of the power source to the power source connecting portion.

Abstract: A bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, and a torque transmitting profile. The sprocket body has an outer periphery and an inner periphery positioned radially inwardly from the outer periphery with respect to a rotational center axis of the bicycle sprocket. The plurality of sprocket teeth is disposed on the outer periphery of the sprocket body. The torque transmitting profile is positioned around the inner periphery of the sprocket body. The torque transmitting profile includes at least ten internal spline teeth. The at least ten internal spline-teeth include at least one first internal spline-tooth, at least one second internal spline-tooth and at least one third internal spline-tooth. The at least one internal first spline-tooth, the at least one second internal spline-tooth and the at least one third internal spline-tooth are different in shape from each other.

Abstract: A bicycle component controller is basically provided with a data storage device and a processor. The data storage device contains sprocket assembly information of at least one sprocket assembly. The processor is configured to perform a gear shift control based on the sprocket assembly information. The sprocket assembly information of the at least one sprocket assembly at least includes a total sprocket number and shifting gate information. The single shifting distance of the sprocket assembly information corresponds to an axial spacing between adjacent sprockets of the at least one sprocket assembly.

Abstract: A bicycle sprocket arrangement comprises a smaller sprocket and a larger sprocket. The larger sprocket has at least one upshifting facilitation area configured to facilitate an upshifting operation in which a bicycle chain is shifted from the larger sprocket toward the smaller sprocket. The at least one upshifting facilitation area includes an upstream tooth, an intermediate tooth, and a downstream tooth. The upstream tooth has a first recessed portion. The intermediate tooth has a second recessed portion. The downstream tooth has at least one of a third recessed portion and a chamfered portion. The at least one of the third recessed portion and the chamfered portion are separated from the second recessed portion.
