<p>In a human powered vehicle having at least three wheels (1, 2) joined together by a frame (8) which carries a bicycle drive mechanism (3, 4), and having a seat (11) for at least one person and also an optionally removable weather shield (17, 18), there is provided a rigid frame part (9) which joins together the front end and the back end of the supporting frame (8), which is firmly connectable to the supporting frame (8) and which extends arcuately over the seat (11) and carries the weather shield (17, 18). This permits lightweight construction of the vehicle, which makes it particularly suitable for human powered propulsion. <IMAGE></p> |
