<p>The device has a flexible blade (1) directed in a direction parallel to or forming a small angle with a pedaling direction (2), where the blade is made of a low density core reinforced by composite material. The blade forms an integral part of a frame (4) of a bicycle, where the frame is made of composite material. The pedaling direction forms an angle (3) less than 45 degrees with respect to a horizontal plane. A saddle (6) slides on the blade, and is locked on the blade by a tightening device (5). The saddle has a support for a posterior part of a basin of a cyclist.</p> |
