Bicycle-drive mechanism worked by arms and legs

摘要

The beams are caused to swing by the arms and legs, and they can be coupled via a reversing drive mechanism. They can cause the leg pendulums to swing via the pendulum supports, and the leg pendulums can turn the driving axle via freewheels working in the same direction and the driving sprocket or pinion fixed to the axle. A spring-mounted torso support turning on the steering column can be arranged to steer the bicycle by body movements.
