Abstract
The invention comprises a system for a bicycle or similar vehicle to allow shock isolation at the location of the seat or handle bar mounting or other locations. The suspension system includes a hydraulically actuated system as well as a variable rate progressive dampening assembly. The hydraulic fluid is also utilized to lubricate the moving portions of the system to promote proper function and extend the useful life thereof. The system also has a variable spring preload to accommodate different sized riders. The system is cost effective and yet extremely durable and may be retrofit for use with existing bicycles.
