Abstract
A recumbent bicycle, the manufacture thereof, and apparatus for forming same, is provided. The recumbent bicycle generally includes a frame having joined forward and rearward frame portions. The forward frame portion is a sit-up bicycle frame adpated to support a steerable front ground engaging wheel. The rearward frame portion is adapted to support a suspension assembly and substantially bear a rider thereon. Preferably, the sit-up bicycle frame includes a head tube, down tube, bottom bracket, seat tube, chainstay, seatstay, and dropouts, and the rearward frame portion includes a supplemental chainstay. The rearward frame portion is joined to the forward frame portion such that the supplemental chainstay rearwardly extends from the dropouts as a substantial continuation of the chainstay of the forward frame portion. The apparatus of the subject invention permits transformation of a sit-up bicycle into a recumbent bicycle, and generally includes a frame extension appliance for affixation to the frame of the sit-up bicycle so as to rearwardly extend therefrom. The extension appliance is adapted to support a suspension assembly, and substantially bear a rider thereon.
