Abstract: A bicycle chain comprises a first outer link plate. The first outer link plate comprises a first outer-link end portion, a second outer-link end portion, a first outer-link intermediate portion, and a first outer-link longitudinal centerline. The first outer-link end portion, the second outer-link end portion and the first outer-link intermediate portion define a first outer-link outer peripheral edge. The first outer-link outer peripheral edge comprises a first outer-link end edge, a second outer-link end edge, and a pair of first outer-link intermediate edges. A first radial distance is defined from a first outer-link center axis to the first outer-link end edge in a perpendicular direction. A minimum distance is defined between the pair of first outer-link intermediate edges in the perpendicular direction. The minimum distance is smaller than 200% of the first radial distance and is equal to or larger than 5 mm.

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 a rotational speed of the motor as the acceleration of the human-powered vehicle increases in a case where the derailleur has been actuated to change the transmission ratio and a predetermined condition related to pedaling is satisfied.

Abstract: A bicycle derailleur includes a base member, a movable member, a link member, a chain guide, a biasing mechanism and a switching member. The link member movably couples the movable member to the base member. The chain guide is pivotally coupled to the movable member about a pivot axis. The biasing mechanism is operatively disposed between the movable member and the chain guide, and biases the chain guide with respect to the movable member about the pivot axis in a first direction in a biasing state. The switching member is configured to selectively switch the biasing mechanism between the biasing state and a releasing state. The biasing mechanism biases the chain guide less in the releasing state than the biasing state. The switching member is disengaged from the biasing mechanism in the biasing state. The switching member is engaged with the biasing mechanism in the releasing state.
