A bicycle may include a rear suspension system to absorb forces impacting on the bicycle by allowing a rear wheel of the bicycle to be displaced relative to the bicycle frame. The rear suspension system may be adjusted in some versions to affect the travel path of the rear wheel as well as the leverage ratio curve to suit the rider's preference. The bicycle may include a frame and a rear suspension system including a swingable member configured for operative association with the frame and including a rear frame including a bottom member and a top member extending upwardly from the bottom member, such that the top member of the rear frame does not move relative to the bottom member of the rear frame when the swingable member moves. The rear suspension system may also include a link system configured for operative association with the swingable member, the link system including a first link pivotally connected with the swingable member so as to allow the swingable member to swing and a second link slideable along a guide member so as to provide a translational pivoting of the swingable member relative to the frame.
