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, an electric actuator configured to actuate the derailleur, 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 upon determining the derailleur has been actuated with the electric actuator to change the transmission ratio and a predetermined condition related to pedaling is satisfied. The electronic controller is configured to control the electric actuator so as not to change the transmission ratio until a first condition related to shifting is satisfied in a case where the derailleur is actuated.

Abstract: A rear sprocket assembly comprises a first sprocket and a lock device. The lock device includes a first lock member and a second lock member. The first lock member includes a first axial end and a second axial end. The second lock member includes a third axial end and a fourth axial end. The third axial end is configured to be attached to the second axial end of the first lock member in an assembled state where the first sprocket and the lock device are assembled as one unit. The fourth axial end has at least one radial projection configured to abut against a first sprocket in the axial direction in the mounting state. The lock device is configured so that the first sprocket is slidable relative to the lock device in the axial direction in the assembled state and before the mounting state.

Abstract: A bicycle pedal is provided with a pedal shaft and a pedal body. The pedal shaft has a first end portion configured to attach to a bicycle crank, a second end portion on an opposite side of the first end portion in an axial direction with respect to a rotational center axis of the pedal shaft, and a contact portion between the first end portion and the second end portion. The pedal body has a body part rotatably supported by the pedal shaft and a load receiving part at a position corresponding to the contact portion of the pedal shaft. The load receiving part receives a load from the contact portion of the pedal shaft. The load receiving part is at least partly spaced from the contact portion under a no load condition and contacts the contact portion upon a load applied to the pedal body from a rider.

Abstract: A bicycle crank assembly includes a fixing member for fixing a sprocket to a crank arm. The fixing member includes a radially-extending projection, to prevent the sprocket from moving relative to the crank axle in an axial direction, and an axially-extending base portion, which is secured to the crank arm. A contact part is provided on an inner periphery of the base portion and contacts the crank axle or is provided on the crank axle and contacts the base portion. The contact part permits force to be transmitted between the crank axle and the fixing member to limit flexing of the crank axle assembly.
