Abstract
A hub assembly for a human-powered vehicle comprises a hub axle, a first rotatable member, a second rotatable member, and a rotation control structure. The rotation control structure couples the first rotatable member to the second rotatable member to transmit a first input rotation of the first rotatable member to the second rotatable member at a first ratio of a first output rotation of the second rotatable member to the first input rotation of the first rotatable member. The rotation control structure couples the second rotatable member to the first rotatable member to transmit a second input rotation of the second rotatable member to the first rotatable member at a second ratio of a second output rotation of the first rotatable member to the second input rotation of the second rotatable member. The second ratio is different from the first ratio. The second ratio is larger than 0.
