Why is BikeCushion inventive? Because of its shape and the way it holds and controls air. DESIGN GOALS    Patent 7,648,198 B1 - ABSORB SHOCK + VIBRATION - ALLOW BLOOD FLOW - VENTALATION - FIT ALL MOTOTORBIKES - FIT MOST RIDERS Reducing shock on your spine from a long ride will reduce fatigue and pain. To absorb shock and vibration the cushion must have a large interface between you and the bike in a medium that would deaden shock. Air has good cushioning qualities including insulation from vibrations and compressibility to absorb shock. Air also can distribute your weight evenly to allow blood flow into your skin. Lack of blood flow creates the pain. The trick is to place the air where it is needed and control where it goes. The cover is made from breathable spandex and the shape of the cushion allows air to flow underneath you creating cooler seating. To fit as many motorbikes as possible required two sizes, a 13”wide sport and a 15”wide cruiser. Adding or deleting air is the way to fit the individual for the best fit and benefit.
