Abstract

A shock absorbing bicycle frame apparatus includes a bicycle frame assembly having a seat tube, upper frame tube, lower frame tube and handle bar tube welded in a generally triangular construction. A shock absorber attachment means extends forwardly from the seat tube at a position below the upper frame tube, and a shock mounting bridge is pivotally engaged with the shock absorber attachment means. A rear wheel support fork consists of a pair of parallel, spaced apart connector rods mounted at a lower end portion to opposing sides of a rear wheel axle and at an upper end portion to the shock mounting bridge. A shock absorbing means is mounted to the shock mounting bridge so as to extend forwardly away from the seat tube. The shock absorbing means includes a shock rod that extends from and is pivotally engaged to the seat tube ears so that road shock energy delivered to the rear wheel is transferred through the rear wheel support fork to the shock absorbing means for absorbing shocks. A pair of rear wheel stabilizer rods extend between and are pivotally connected with the lower end portion of the connector rods and the seat tube in a position adjacent to the lower frame.
