<p>The invention concerns a cycle designed to provide vertical and ergonomic riding positions, while preserving a standard pedal axle. Said cycle consists of a standard rear part and an original front part comprising handle bars (1) considerably raised with respect to the saddle plane (2) with variable length (3) and a small steered wheel (6) borne by a handlebar/fork assembly (1 and 5) guided by a head tube (4) closer and parallel to a saddle/chainset axis forming an angle of (72 ± 5 degrees) with the horizontal. The shape and position of the intermediate tubes (7) and (8), or other frame parts, bear no direct influence on the invention. They simply provide the frame with rigidity. The inventive cycle, with or without motor, is adapted to all types of terrain and is particularly suited for urban surroundings.</p> |
