ABSTRACT:
A suspension assembly for a bicycle frame which elastically supports a rear frame member, which in turn rotatably supports the rear wheel. The suspension assembly is positioned around the bottom bracket such that the rear frame member pivots about the axis of the bicycle crank axle of the bottom bracket. This arrangement allows the rear wheel and rear frame member to move relative to the main frame, without any adverse affects to the drive train assembly. In the preferred embodiments, drive train assembly can be either a chain drive or a shaft drive. The suspension assembly includes an inner suspension member with the crank axle mounted therein, an intermediate suspension member surrounding the inner suspension member with at least one shock-absorbing element interposed therebetween, and an outer suspension member surrounding the intermediate suspension member with at least one shock-absorbing element interposed therebetween. In the preferred embodiment, each of the shock-absorbing elements includes a plurality of biasing members.
