A gas spring suspension system that maximizes the travel of the suspension system. The suspension system includes a first tube and a second tube slidable within the first tube. A piston assembly is slidably mounted in the second tube for changing the pressure in the second tube. A floating piston is slidably mounted in the second tube. A first gas chamber biases the first and second tubes apart from each other while a second gas chamber biases the first and second tubes toward each other. A third gas chamber exists between the floating piston and an end of the first tube. The floating piston has a configuration such that when a pressure in the third gas chamber is greater than a pressure in the second gas chamber, the floating piston displaces within the second tube to decrease the pressure in the third gas chamber.
A front fork has an air pump provided in one of a pair of front pipes at respective sides of the front fork. The air pump has an axle inserted into the front pipe. One end of the axle is provided with a piston, and the other end of the axle is connected to a handle. An air chamber is formed in the front pipe.
