Title:
CYCLE, IN PARTICULAR A BICYCLE
Document Type and Number:
WIPO Patent Application WO2000003913
Kind Code:
A3
Abstract:
A cycle (1) on which the user can assume a comfortable upright position, that has a frame (3) with a mainly vertically directed seat tube (20) and a handlebar (9) with a steering tube that is directly fastened to a front fork (11). In front of the seat tube (5) there is a seat (21) that can be slid along the seat tube (5) to adjust the height. This construction, with a cycle with an upright position of the user, allows a broad range of adjustment of the seat (21), making the cycle suitable for users of any size. The upright position of the user can be improved even more by placing the bottom bracket axle (37) of the cycle lower than 10 cm above an imaginary line through the wheel axles (27, 48) of the front and rear wheel (12, 13), preferably even under this line.
