Abstract: A front derailleur is provided for mounting to a bicycle having a crank axis. The front derailleur is provided with a base member, a chain guide and a link mechanism. The base member is mounted on the bicycle for positioning in a predetermined adjustment direction. The chain guide guides the chain. The link mechanism movably couples the chain guide to the base member. The link mechanism includes a first link member pivotally arranged in relation to the base member about a first link axis and pivotally arranged in relation to the chain guide about a second link axis. The first link axis and the second link axis are arranged non-parallel and non-orthogonal to the predetermined adjustment direction when viewed from the axial direction of the crank axis in a state where the base member is mounted to the bicycle.

Abstract: An electric front derailleur is provided with a base member, a movable member, a driving unit and a controller. The base member includes a bicycle mounting portion. The movable member moves with respect to the base member. The controller selectively operates the driving unit with one of a first mode which moves the movable member between a first end position and a second end position, and a second mode which moves the movable member between a third end position and a fourth end position. The controller operates the driving unit to selectively position the movable member at first, second and third stop positions while in the first mode. At least one of the third and fourth end positions differs from the first and second end positions. A first distance between the first and second stop positions differs from a second distance between the second and third stop positions.

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 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 lock device comprises a first lock member and a second lock member. The first lock member includes a first axial end, a second axial end, and a first surface. The first axial end is configured to be detachably attached to a sprocket support body of the rear hub assembly in a mounting state where the plurality of rear sprockets is mounted to the rear hub assembly. The second lock member includes a third axial end, a fourth axial end, and a second surface. The third axial end is configured to be attached to the second axial end of the first lock member in an assembled state where a smallest sprocket and the lock device are assembled as one unit. The lock device is configured so that the smallest sprocket is slidable relative to the lock device in the axial direction in the assembled state and before the mounting state.

Abstract: A human-powered vehicle includes a crank axle, a first rotational body, a wheel, a second rotational body, a transmission body that transmits a driving force between the first rotational body and the second rotational body, a derailleur configured to operate the transmission body to change a transmission ratio, and a motor configured to drive the transmission body. A control device has an electronic controller configured to control the motor and drive the transmission body with the motor so as to change at least one of a rotational angle of the motor and an output torque of the motor in correspondence with a state of the human-powered vehicle upon determining the derailleur has been actuated to change the transmission ratio and a predetermined condition related to pedaling is satisfied.
