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.

A suspension system comprising:
- a) a front frame;
- b) a rear frame;
- c) an upper link pivotably attached to the front frame at a front upper pivot point and the rear frame at a rear upper pivot point, the front and rear upper pivot points defining an upper base line;
- d) a lower link pivotably attached to the front frame at a front lower pivot point and the rear frame at a rear lower pivot point, the front and rear lower pivot points defining a lower base line;
- and
- e) a tie link pivotably attached to the upper link at a top pivot point and the lower link at a bottom pivot point, the top and bottom pivot points disposed between the upper base line and the lower base line.
A suspension system comprising:
- a) a front frame;
- b) a rear frame;
- c) an upper link pivotably attached to the front frame at a front upper pivot point and the rear frame at a rear upper pivot point;
- d) a lower link pivotably attached to the front frame at a front lower pivot point and the rear frame at a rear lower pivot point;
- and
- e) a tie link pivotably attached to the upper link at a top pivot point and the lower link at a bottom pivot point;
- f) wherein a tie link line defined by the top and bottom pivot points extend between the front and rear upper pivot points of the upper link and the front and rear upper pivot points of the lower link.
