Reciprocating rail movement suspension system
Generally, examples described herein may take the form of a bicycle including a front frame, a rear frame operably associated with the front frame and configured for coupling to a rear wheel, and a suspension system operably associated with the front frame and the rear frame. The suspension system includes a first connection structure operably coupling the front frame to the rear frame and a first sliding body pivotally coupled to the rear frame and configured to travel in a first direction along a substantially linear travel path and in a second direction opposite the first direction along the substantially linear travel path as the suspension system is compressed.
