Six-Bar Rear Bicycle Suspension

Tech ID: 18788 / UC Case 2006-364-0


Current bicycle rear suspension designs cannot ensure that the axle of the rear wheel follows a circle around the bottom bracket that holds the pedal wheel axle. This means that pedal forces cause the suspension to deflect, which wastes rider energy.

Technology Description

University researchers have developed a new rear suspension design which introduces additional control linkage that ensures the wheel axle follows a circular trajectory around the bottom bracket that holds the axle of the pedal wheel.


This invention can be used for bicycles designed for mountainous terrain, but may also find use in touring bicycles where rider comfort is a primary concern.
