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 sprocket arrangement comprises a largest sprocket, a smallest sprocket, and a plurality of intermediate sprockets. A first quotient is obtained if a total tooth-space number of the large sprocket is divided by a half of the tooth-space number difference. The first quotient is an even number with respect to all sprockets of the plurality of intermediate sprockets. A second quotient is obtained if the total tooth-space number of the small sprocket is divided by a half of the tooth-space number difference. The second quotient is an even number with respect to all sprockets of the plurality of intermediate sprockets excluding a largest intermediate sprocket of the plurality of intermediate sprockets.

Abstract: A bicycle rear sprocket assembly is basically provided that includes a first sprocket including a first sprocket body and a plurality of first sprocket teeth provided to an outer periphery thereof. Each of a plurality of first circumferential areas has a first circumferential length. A first total number of the plurality of first circumferential areas is an even number. A first circumferential area counting number from a driving surface of a first shifting initiation tooth to a driving surface of a second shifting initiation tooth in a driving rotational direction of the bicycle rear sprocket assembly is an odd number. A second circumferential area counting number from the driving surface of the second shifting initiation tooth to the driving surface of the first shifting initiation tooth in the driving rotational direction is an odd number. The first circumferential area counting number is different from the second circumferential area counting number.

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: 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.
