Abstract

A bicycle rear suspension system includes a front part including a top tube, a down tube, a head tube and a seat tube. A rear part of the bicycle rear suspension system includes two seat stays and two chain stays. The seat stays have first ends pivotally connected to the dropouts on the first ends of the chain stays and two second ends pivotally connected to a first end of a connection member at a first pivot point. Two second ends of the chain stays are pivotally connected to a bridge between the down tube and the seat tube. A second end of the connection member is pivotally connected to the top tube. A cylinder has a first end pivotally connected to the bridge and a second end pivotally connected to a mediate portion of the connection member at a second pivot point.
