Abstract:
A rear suspension mechanism for a rear wheel assembly of a vehicle having a frame rotatably supporting said rear wheel assembly to isolate a rider from irregularities in the ground during operation of the bicycle, comprising:a semi-elliptical swing arm having a lower leg and an upper leg, said rear wheel assembly having an axle supported at a vertex, one of said lower and upper legs being connected to said frame; a rocker arm pivotally connected to the other of said lower and upper legs and being pivotally connected to said frame; and said swing arm including a flexor element to permit said upper and lower legs to diverge when a generally vertical force is applied to said rear wheel, said rocker arm permitting said upper and lower legs to diverge, said flexor element being formed to focus bending action of said swing arm at said flexor element to impart a forward movement-inducing moment relative to said rear wheel assembly axle.
