<p>A two-wheel driving lying bicycle comprises a front wheel(11) driven by a front wheel ratchet wheel (22), which is meshing with and directly driven by a front wheel rack (21) which makes rectilinear motion. The bicycle also comprises a rear wheel (2) driven by a rear wheel ratchet wheel (19), which is meshing with and directly driven by a rear wheel rack (15) which makes rectilinear motion. Because the bicycle is driven by two wheels, the riding speed is fast and the body-building effect is improved.</p> |
