ABSTRACT:
A vehicle frame is constructed of a frame body including a head component for supporting a front wheel, a seat supporting component for supporting a seat, and a frame component coupled to the head component and to the seat supporting component. The frame component defines a sealed space that is hermetically sealed from the head component and the seat component. The frame component includes a gas opening disposed on a side surface thereof and displaced from the head component and the seat component so that the sealed space may be charged with a compressed gas. If desired, the frame component may include a separate opening for supplying compressed gas to another component mounted on the bicycle.
