ABSTRACT APPARATUS FOR ASSEMBLING A BICYCLE FRAME The invention is an apparatus for assembling a bicycle frame of the type in which the head tube, bottom bracket and seat post bracket include stubs for receiving connecting tubes in a press fit. The apparatus includes a base, a clamp for receiving the bottom bracket, a carriage for receiving the head tube, and a swing arm Which pivots about the axis of the bottom bracket clamp and receives the seat post bracket and seat mast of the bicycle frame. Double-acting cylinder motors are mounted on the base for displacing the carriage toward the bottom bracket clamp and for pivoting the swing arm toward the carriage. A cylinder motor is mounted on the swing arm to urge the seat bracket toward the bottom bracket. A computer control selectively actuates the cylinders to urge the bottom bracket, seat post bracket, and head tube toward each other in a substantially continuous motion, thereby urging their respective stubs into the ends of the connecting tubes to form the bicycle frame.
