ABSTRACT:
An attachment for a standard bicycle which is installed by cutting the bicycle frame members in a substantially vertical plane and rigidly attaching a pair of hingedly connected bars to the cut ends. The bars may be welded to the bicycle frame members, or affixed at their ends to tubular members which are bolted or otherwise attached to the front and rear portions of the bicycle frame members. Movement about the hinged connection selectively places the bicycle either in the standard riding position or in a folded position with the front and rear wheels side-by-side.
