Abstract: A bicycle crank assembly having a rotational center axis is basically provided with a crank member and a sprocket member. The crank member includes a support portion that extends in the axial direction and an arm portion that is integrally rotatable around the rotational center axis with the support portion. The sprocket member includes a sliding portion that extends in the axial direction that is integrally rotatable with respect to the support portion and that is displaceable in the axial direction. The bicycle crank assembly is constructed to achieve high strength and to suppress the decrease in the efficiency of the rotation transmission from the crank member to the sprocket member in a crank assembly in which the sprocket member is movable in the axial direction.

Abstract: A bicycle crank assembly has a rotational center axis and comprises a crank member, a sprocket member, a sliding mechanism, a first stopper member, a second stopper member and a damping member. The crank member rotatably is arranged around the rotational center axis. The sprocket member is integrally and rotatably attached to the crank member. The sliding mechanism movably coupling the sprocket member in an axial direction with respect to the crank member. The first stopper member is attached to the crank member. The second stopper member is attached to the sprocket member. The damping member is attached to at least one of the first stopper member and the second stopper member. The damping member is configured to contact the other of the first stopper member and the second stopper member while the sliding mechanism is in operation.

Abstract: A bicycle crank assembly comprises a crank axle, a first crank arm, and a battery holding structure. The crank axle comprises a cavity and a first end portion. A battery unit is to be provided in the cavity. The first end portion has a first end opening which is in communication with the cavity. The first crank arm is configured to be mounted on the first end portion. The battery holding structure is configured to hold the battery unit in the cavity. The battery holding structure is configured so that the battery unit is replaceable through the first end opening in a state where the first crank arm is mounted on the first end portion of the crank axle.
