The swing arms, control arms, and hub plates are configured to balance the forces applied to the rear wheel by the chain during pedaling so as to prevent energy absorbing movement of the rear suspension as the result of such pedaling. A shock absorber is also connected to the swing arms to absorb shocks during riding. The suspension of the present invention also is configured to provide improved traction during pedaling uphill or over uneven surfaces. | |
