The members move in opposite direction pulling and releasing a pair of chain segments that each a freewheel. Each freewheel drives an axle when rotated in one direction and coasts in the opposite direction. A drive gear is attached to the axle and supplies power to a driven gear attached to a multi-speed internal gear hub. A brake is also attached to the hub. An optional supplemental source of motive power such as an electric motor or gasoline engine can also be included.
