Abstract: A high pressure compressed air tank has an inlet and an inlet valve which is opened when a fitting of a service station air hose is pressed against the inlet. High pressure compressed air is then forced from the service station air hose into the tank. The inlet valve prevents compressed air from escaping from the tank. An outlet fitting connected to the tank has an outlet valve therein. The outlet fitting is pressed against the tire valve housing of a bicycle, causing the tire valve to open. High pressure compressed air from the tank is then forced into the bicycle tire, thereby inflating it. The tank is attached to a frame member of the bicycle by means of a quick-release bracket. An air horn operable by means of a button valve and a pressure gauge are attached to the high pressure air tank.
