ABSTRACT:
A rugged but inexpensive bicycle frame comprises a tubular head post welded to the flattened forward end of a relatively large diameter tubular crossbar. The rear end of the crossbar is flattened laterally and provided with a concave rear edge. A tubular rear fork has a rounded bridge portion which is fitted to the crossbar rear edge so that the nominal plane of the rear fork is perpendicular to the headpost. Welds permanently connect the front and rear ends of the crossbar to the headpost and rear fork bridge portion respectively. There are openings in the top and bottom walls of the crossbar just forward of the rear end thereof for receiving a tubular seat post so that the lower end of set seat post extends appreciably below the crossbar. Welds permanently connect the seat post to the crossbar. A short tube is welded to the lower end of the seat post to support the pedal crank.
