ABSTRACT:
A rear suspension system for a two wheel cycle, such as a bicycle or motorcycle, having a main frame which includes a mount for a steering apparatus to which the front wheel is mounted, and means for mounting a rear frame assembly which the rear wheel is mounted. The vertically pivotable rear frame assembly includes a single primary swingarmwhich extends rearwardly from a pivotal connection on the main frame, which pivot has an axis parallel to the rear wheel axis. The rear wheel is mounted to a primarily vertical junction member, which itself is attached by a second pivotal and parallel connection at the rear end of the main swingarm. A single secondary swingarm is also attached to the vertical junction member, by a third pivotal and parallel connection at some vertical distance below the second pivotal connection, and extends forwardly from the junction at an angle and spacing relative to the main swingarm. The secondary swingarm mounts to the main frame at some vertical distance below the main swingarm pivotal connection, via a fourth pivotal and parallel connection. Both arms pass along one side of the cycle only, with the rear wheel being mounted in a cantilever fashion from a real wheel mounting means attached to the vertical junction member which is also on the same one side.
