摘要： 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.

摘要： 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.

摘要： A bicycle rear sprocket comprises a sprocket body and a plurality of sprocket teeth. The plurality of sprocket teeth includes a plurality of first teeth. Each tooth of the plurality of first teeth has a driving surface and a non-driving surface provided on a reverse side of the driving surface in a circumferential direction with respect to the rotational center axis. Each tooth of the plurality of first teeth has an axial maximum tooth-width and an axial driving-surface tooth-width. The axial maximum tooth-width is defined in an axial direction of the rotational center axis as a maximum width in each tooth of the plurality of first teeth. The axial driving-surface tooth-width is smaller than the axial maximum tooth-width. The plurality of first teeth accounts for at least 25% of the plurality of sprocket teeth.

摘要： 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.

摘要： A front derailleur is basically provided with 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 link mechanism includes a cable attachment portion that is configured to be attached to the operation cable. The cable guiding structure guides the operation cable from the cable attachment portion. The cable guiding structure is disposed on at least one of the base member and the link mechanism. The cable guiding structure has a cable exit that is arranged such that the operation cable exits forwardly from the cable guiding structure towards the front of the bicycle.
