摘要

The folding ski bike has ski runners (5,14) at the front and rear instead of wheels. The front runner is mounted on a metal block (6) with a pivot (7) at the lower end of a steering column (3) carrying handlebars (4). The steering column is mounted in sleeve (8) with a hinged connection (9) to the lower end of the front part (1) of the frame. A saddle tube (12) at the top holds a saddle (13). The rear frame member (2) holds a pivoting metal block (15) attached to the rear ski runner. The plate (16) is fastened to the top end of the front part of the frame. The rear frame member can swing on a central pivot (17) on the plate when the bike is folded. There are fastening bolts (18,19) and a wire (21) connecting the two frame members and preventing them spreading.
