Abstract
A rear suspension of a bicycle may have an upper link and lower link which are pivotally connected to both a front frame and a rear frame of the bicycle such that the rear frame may rotate up and down about the front frame/front sprocket. A shock absorber may be pivotally connected to the upper link to absorb any impact forces imposed on the rear wheel and transferred to the upper link as the rear frame rotates up and down. Also, the upper link may be interconnected to the lower link with a tie link which allows the upper and lower links to work in conjunction with each other such that pedal setback is negligible when the rear wheel rides over bumps along the bike trail. Additionally, the tie link equalizes the forces caused by the rider's weight and pedaling forces.
