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 upon determining the derailleur has been actuated to change the transmission ratio and a predetermined condition related to pedaling is satisfied, and control the motor to increase a rotational speed of the motor as a difference of a first rotational speed, which is calculated in correspondence with a rotational speed of the wheel and the transmission ratio, and a predetermined rotational speed or a rotational speed in a predetermined range increases.

Abstract: A bicycle rear derailleur includes a base member, a chain guide, a movable member and a first link member. The base member is configured to be mounted to a bicycle frame at a frame mounting axis. The chain guide includes a first pulley rotatably arranged around a first pulley axis in a first pulley plane. The movable member pivotally supports the chain guide about a pivot axis. The first link member moves the chain guide between first and second lateral positions. The first lateral position is closer to a bicycle center plane. The first pulley plane intersects the first link member in a state where the chain guide is located at the second lateral position. The frame mounting axis is spaced from the pivot axis by a distance equal to or larger than eighty-nine millimeters when the chain guide is at the first lateral position.

Abstract: A bicycle tensioner apparatus comprises a first base member, a second base member, and a tensioner. The second base member is movably coupled to the first base member. The tensioner is configured to contact a driving-force transmitting member to apply tension to the driving-force transmitting member. The tensioner is coupled to both the first base member and the second base member. The tensioner is movable relative to at least one of the first base member and the second base member in response to a relative movement between the first base member and the second base member.

Abstract: A front derailleur includes a base member, a chain guide, a link mechanism and a cable guiding structure. The base member is fixedly coupled to a bicycle. The chain guide is configured to guide a chain. The link mechanism movably couples the chain guide to the base member between a retracted position and an extended position in response to movement of an operation cable. The cable guiding structure has one of bore, recess and groove formed on the link mechanism to guide the operation cable. The operation cable exits forwardly from the cable guiding structure within a sector having an angle of 150 degrees around the crank axis from an upper radius lying in a first plane that is perpendicular to a second plane containing a crank axis and a rear wheel axis.
