Abstract: A bicycle front sprocket comprises a sprocket body and at least one sprocket tooth. The sprocket body includes a crank arm mounting portion including a first mounting axial surface facing toward an axial bicycle-center plane in an axial direction in a state where the bicycle front sprocket is mounted to the bicycle frame. The at least one sprocket tooth has a first chain-engagement axial surface facing toward the axial bicycle-center plane in the axial direction in a state where the bicycle front sprocket is mounted to the bicycle frame. The first chain-engagement axial surface is offset from the first mounting axial surface toward the axial bicycle-center plane in the axial direction. An axial distance is defined from the first mounting axial surface to the first chain-engagement axial surface in the axial direction and is equal to or larger than 6 mm.

Abstract: A bicycle transmission apparatus comprises a base member, a first transmission member, a second transmission member, a first coupling member, a first guide structure, a switching device, and a transmission controller. The switching device is configured to switch a position of the first transmission member relative to the base member in an axial direction between a first axial position and a second axial position. The transmission controller is configured to control the switching device and the first guide structure so as not to change a first engagement state of the first coupling member from one cogwheel to another adjacent cogwheel among first cogwheels when the first transmission member moves relative to the base member in association with a movement of the first guide structure relative to the base member to change a second engagement state of the first coupling member from one cogwheel to another adjacent cogwheel among second cogwheels.

Abstract: A bicycle hub assembly comprises a hub axle, a hub shell, a sprocket support body, and a clutch. The sprocket support body is rotatably mounted on the hub axle to rotate about a rotational axis. The sprocket support body is rotatable relative to the hub axle and the hub shell about the rotational axis. The clutch has a first coupling state where a pedaling rotational force is transmitted from the sprocket support body to the hub shell in a first rotational direction during pedaling, a first release state where the hub shell is rotatable relative to the sprocket support body in the first rotational direction during coasting, and a second coupling state where a coasting rotational force is transmitted from the hub shell to the sprocket support body in the first rotational direction during coasting.

Abstract: A bicycle sprocket comprises sprocket teeth. The sprocket teeth include a first tooth and a second tooth. The first tooth has a chain-engaging axial width which is larger than a first distance defined between opposed inner link plates of a bicycle chain and which is smaller than a second distance defined between opposed outer link plates of the bicycle chain. The second tooth has a chain-engaging axial width which is larger than the first distance and which is smaller than the second distance. The first tooth and the second tooth are spaced apart from each other in a circumferential direction of the bicycle sprocket to define a space which is free of a tooth configured to engage with the bicycle chain.

Abstract: A derailleur comprises a base member, a movable member, a link member, and a biasing mechanism. The movable member is configured to be movable with respect to the base member between a retracted position and an extended position. The link member is configured to movably couple the movable member to the base member. The biasing mechanism is configured to bias the link member such that the movable member is disposed at one of the retracted position and the extended position. The biasing mechanism comprises a biasing member and an intermediate member. The biasing member has a first end portion. The intermediate member is separately provided from the movable member and the link member so as to transmit biasing force of the biasing member from the first end portion to one of the movable member and the link member through the intermediate member.

Abstract: A bicycle component actuation apparatus basically comprises a base member; a user operating member and a controller. The user operating member is movably mounted to the base member from a rest position to a first operated position. The controller detects operation of the user operating member to operate first and second electric components, one of which is not a shifting device. The controller operates one of the first and second electric components upon the controller detecting the user operating member being moved to the first operated position. The controller operates at least the other of the first and second electric components upon the controller detecting the user operating member remaining at the first operated position for a period of time longer than a first prescribed time.

Abstract: A control device for a human-powered vehicle includes an electronic controller. The human-powered vehicle includes a motor that applies a propulsion force to the human-powered vehicle and a transmission that shifts a transmission ratio of the human-powered vehicle between a plurality of shift stages. The electronic controller is configured to control the motor. The electronic controller is configured to decrease an upper limit value of an output of the motor in an up-shift operation. The electronic controller is configured to decrease the upper limit value in a down-shift operation. The electronic controller is configured to control the motor so that the upper limit value in the up-shift operation performed between two predetermined ones of the shift stages that differ in the transmission ratio by one stage differs from the upper limit value in the down-shift operation performed between the two predetermined ones of the shift stages.
