Bicycle and the like with multiple gears (14), chain transmission (6) and axis of the cranks (16) of the pedal unit (1) placed on the outside of the rear wheel, inside the upper arc bounded by A and B symbols, new pedalling system optimising the relationship between the means of transport and its user. The cyclist's position is prone (fig.1), a condition possible thanks to the body supporting "balancer" (8, 9) (fig.4); it allows an optimal weight distribution and cardio-vascular, respiratory and muscular optimisation, which leads to a maximum energy output. The advantageous aspects are: maximum aerodynamic penetration due to the driver's prone position; maximum exploitation of muscular output due to the antigravitational rotation of thighs; better venous and lymphatic circulation thanks to lower abdominal pressure; better cardio-respiratory function, due to easier venous circulation; maximum protection of the spine by supporting the rachis; minimum perineum shock thanks to the saddle (11) supporting the gluteus; maximum stability of the vehicle thanks to ground-hub pedal block-system; reduced weight of the rotating parts thanks to the compactness of the mechanism of transmission. |
