ABSTRACT:
A suspension bicycle includes swing arms, control arms and hub plates connected to the seat riser tube of the frame in a trapezoidal arrangement balanced to offset forces applied to the rear wheel by the chain to prevent absorption of pedaling energy by the suspension system while still permitting the suspension system to be responsive to changes in road conditions.
