A bicycle crank assembly comprises a sprocket, a crank axle, a movable member, a torque transmitting member, and a bearing structure. The sprocket has a rotational center axis. The crank axle extends along the rotational center axis. The crank axle includes an internal space. The movable member is movably provided in the internal space to move the sprocket in an axial direction of the rotational center axis. The torque transmitting member is to transmit a pedaling torque from the crank axle to the sprocket. The bearing structure is disposed between the movable member and the crank axle to slidably support the movable member in the axial direction. The bearing structure is disposed at a location different from a location of the torque transmitting member in the axial direction.
