摘要： 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.

摘要： A bicycle drive unit comprises a housing configured to be mounted to a first base member. The housing includes a first wall at least partly defining an internal space to at least partly accommodate a bicycle crank having a crank rotational axis. The first wall includes a first transmitting surface disposed to at least partly face upward in a bicycle upright state where the crank rotational axis horizontally extends and the housing is mounted on the first base member. The first transmitting surface is configured to face a first receiving surface of the first base member to transmit an upward force from the housing to the first base member. The first transmitting surface being at least partly disposed below the crank rotational axis in the bicycle upright state.

摘要： A bicycle derailleur is basically provided with a base member, a chain guide, a linkage assembly and a first adjusting member. The chain guide is pivotally supported with respect to the base member between a retracted and an extended position. The linkage assembly includes a first link coupled to the base member about a first pivot axis and coupled to the chain guide about a second pivot axis. The linkage assembly includes a second link coupling the base member to the chain guide. The second link is farther from the bicycle frame than the first link when the base member is mounted to the bicycle frame. The first adjusting member is movably attached to the first link. The first adjusting member is configured to contact one of the base member and the chain guide to restrict movement of the chain guide at one of the retracted and extended positions.

摘要： A bicycle sprocket basically includes a sprocket main body, a plurality of teeth and at least one projecting member. The teeth are disposed along a circumferential direction on a radially outer side of the sprocket main body. The teeth include at least one first tooth and at least one second tooth. The at least one projecting member protrudes from an axial surface of the at least one first tooth. The at least one projecting member is a different material from the teeth. The at least one projecting member and the at least one first tooth define a first chain engaging tooth width for engaging with an outer link of a bicycle chain. The at least one second tooth defines a second chain engaging tooth width for engaging with an inner link of the bicycle chain. The first chain engaging tooth width is greater than the second chain engaging tooth width.
