Abstract

A bicycle, motorcycle or the like is fabricated from a pair of frame sections. A front frame section includes the front fork and wheel, handlebar assembly and seat. A rear frame section includes the crank assembly, pedal assembly and the rear stays and wheel. A shock absorber resiliently couples the front and rear frames to one another intermediate the crank assembly and seat. The lower terminus of the shock absorber is secured to a center support stay of the rear frame, the upper terminus of the shock absorber being coupled to one plurality of selectable locations on a diagonal support of the front frame. The point of coupling alters the relative stiffness of the suspension to compensate for the load imposed on the bicycle seat. The front and rear frames are pivotally coupled to one another forwardly from the lower terminus of the shock absorber in a manner which will permit adjustment of the force required to activate the suspension.
