Abstract: A bicycle sprocket comprises a sprocket body and a plurality of sprocket teeth. The plurality of sprocket teeth includes at least one first axially recessed upshifting-facilitation tooth with respect to a rotational center axis. The plurality of sprocket teeth includes at least one first axially recessed downshifting-facilitation tooth with respect to the rotational center axis. The at least one first axially recessed downshifting-facilitation tooth is adjacent to the at least one first axially recessed upshifting-facilitation tooth without another tooth therebetween in a circumferential direction with respect to the rotational center axis. The at least one first axially recessed upshifting-facilitation tooth and the at least one first axially recessed downshifting-facilitation tooth provide a first continuous recess extending in the circumferential direction.

Abstract: A bicycle hub includes a hub axle, a hub body, an electric power generator, a freewheel and an electric unit. The hub body is rotatable around the hub axle. The electric power generator is disposed between the hub axle and the hub body. The electric power generator is configured to generate electric power by a relative rotation of the hub axle and the hub body. The freewheel is configured to support a sprocket. The freewheel is connected to the hub body and is rotatable around the hub axle. The electric component is disposed between the hub axle and the freewheel in a radial direction with respect to the center axis. The electric unit is electrically connected to the electric power generator.

Abstract: An electric power generator is provided for a human-powered vehicle. The electric power generator includes an axle, a stator, a rotor and a first electrical cable. The axle has a first axial end, and a second axial end. The stator has a first axial stator-end that faces the first axial end of the axle with respect to the rotational center axis and a second axial stator-end that faces the second axial end of the axle with respect to the rotational center axis. The rotor is rotatably mounted on the axle to rotate around a rotational center axis of the electric power generator. The first electrical cable is electrically connected to the stator on the first axial stator-end of the stator. The first electrical cable extends axially through the stator toward the second axial stator-end of the stator with respect to the rotational center axis.

Abstract: A bicycle part includes a housing and a lid. The housing includes an inner peripheral portion, an outer peripheral portion, an end wall portion and a connecting portion. The outer peripheral portion is spaced radially outward from the inner peripheral portion with respect to a center axis of the enclosed area. The end wall portion interconnects the inner peripheral portion and the outer peripheral portion to at least partly define an internal space. The connecting portion interconnects the inner peripheral portion and the outer peripheral portion. The lid overlies the internal space. The lid is welded to the inner peripheral portion along an inner weld path and the outer peripheral portion along an outer weld path. The lid is further welded to at least part of the connecting portion of the housing a connecting weld path connecting the inner weld path and the outer weld path.

Abstract: A bicycle hub unit configured to be stably coupled to a frame of a bicycle includes a hub axle and a rotation restriction member. The hub axle is configured to be coupled to the frame of the bicycle. The rotation restriction member is configured to couple the hub axle to the frame so that rotation relative to the hub axle and the frame is restricted. At least one of the hub axle and the rotation restriction member has a cable guide structure configured to guide a cable, which electrically connects an electric component and an electronic component, in a region including the rotation restriction member in an axial direction parallel to a center longitudinal axis of the hub axle.

Abstract: A component assembly for a human-powered vehicle, the component assembly basically includes a member and a wire rod. The member includes a wall that has a first surface, a second surface opposite the first surface and an opening. The wire rod passes through the opening in the wall of the member. The wire rod includes a first portion located on the first surface side of the wall and a second portion located on the second surface side of the wall. The first portion includes an abutment portion that contacts the first surface adjacent the opening in the wall to suppress axial movement of the first portion of the wire rod through the opening in the wall with respect to an axial direction with respect to a center axis of the opening in the wall.

Abstract: A hub assembly is provided for a human-powered vehicle. The hub assembly includes a hub axle, a hub body, a cable and a cable protector. The hub axle has a first axial end and a second axial end. The hub body is rotatably mounted on the hub axle to rotate around a rotational center axis of the hub assembly. The cable has a first portion disposed inside of the hub assembly and a second portion disposed outside of the hub assembly. The cable protector is movably arranged between a first position and a second position. The second portion of the cable extends along the rotational center axis where the cable protector is in the first position. The second portion of the cable being at least partly restrained in an angled position with respect to the rotational center axis where the cable protector is in the second position.

Abstract: An electrical assembly is provided to a human-powered vehicle. The electrical assembly includes an electric component and an electrical cable. The electrical cable has a first cable-end electrically connected to the electric component and a second cable-end spaced from the first cable-end by an intermediate section of the electrical cable. A cable intersection is formed in the intermediate section of the electrical cable to restrict movement of the electrical cable relative to the electric component.
