摘要

A bicycle frame (4) and a method for its manufacture are described, a closed basic frame, consisting of saddle tube (1), diagonal tube (2) and horizontal tube (3) and having a fixedly attached rear wheel fork (5) and integrated pedal-bearing (10), being formed in such a way that on the one hand the saddle tube (1) projects beyond the connecting point with the horizontal tube in the form of a first section which can be cut to length and on the other hand the diagonal tube (2) projects beyond the connecting point to the horizontal tube (3) in the form of a second section which can be cut to length. By correspondingly shortening these sections which can be cut to length, different frame sizes can be provided starting from an identical basic frame. IMAGE
