ABSTRACT:
The invention provides a bicycle having an improved shock absorbing suspension system and an improved shock absorber for a bicycle. The suspension system comprises a single pair of improved shock absorbers associated with the rear wheel of the bicycle. The improved shock absorber comprises an elongated housing having a hollow cylindrical core which receives a shock absorber rod having a piston head. The core of said housing is provided with a multiplicity of longitudinally disposed shock absorbing springs arranged end to end between the closed end of the housing and the piston head. The springs possess different innate resistances to compression so that the shock absorber has a varying shock absorbing capacity. A return spring is lodged in the housing core on the opposite side of the piston head between the piston head and the end of the housing which receives the shock absorber rod. The return spring provides resistance against the piston head as it moves toward the receiving end of the housing to prevent backlash of the shock absorber rod.
