<p>A bicycle with collapsible frame (11), which incorporates front and rear frame posts (12, 13) and at least one cross beam (15) interconnecting said frame posts. The purpose is to provide a bicycle, which with one or a few simple hand grips in a few seconds can be folded into a compact unit. It furthermore shall have an absolutely rigid frame when the bicycle is in its position of use, and in collapsed position it shall be only little bulky with a substantial extension in one direction only. This has been achieved in that the cross beam (15) of the frame (11) is two-part, that the two parts (15a, 15b) of the cross beam are articulatedly connected to each other and to the frame posts (12, 13), and that the two parts (15a, 15b) of the cross beam at folding of the frame are pivotable towards the front (12) and the rear frame post (13) respectively.</p> |
