ABSTRACT:
A multi-functional stationary bike for gymnastic purpose. A hand-exercise mechanism is mounted above a bike frame and a foot-exercise mechanism is mounted under the bike frame. The hand-exercise and foot-exercise mechanism include respective base and gear mechanisms, wherein the gear mechanism can rotate and roll along the base by use of a gear and several bearings. The hand-exercise and foot exercise mechanism are thus allowed to do reciprocal motions in forward, rearward, upward and downward directions simultaneously, whereby the users may receive an adequate full-body exercise.
