Abstract
A bicycle seat suspension assembly has a parallelogram pivoting linkage connecting the frame with the seat. The parallelogram linkage has a frame link, seat link, upper link, and lower link. An upper spring assembly pivotally engages the frame link on one end and extends up to pivotally engage the upper link. A lower spring assembly pivotally engages the frame link on one end and the lower link on the other end. The suspension assembly is movable between an uppermost position wherein the upper and lower spring assemblies are pre-compressed, and a second position wherein the upper and lower spring assemblies are further compressed. In some embodiments one or both of the spring assemblies have a compression spring that can be swapped out with another compression spring to adjust the spring rate of the assembly.
