A hidden pump removably housed in a seat tube and engaged with the saddle of a bicycle has a cylinder tube and a hollow pumping rod which is movably received in the cylinder tube. Inside the pumping rod which is provided with a piston block at one end and a handle at the other is received a flexible air duct. The air duct having coupling heads is removably engaged with an air outlet nozzle of the pump and an air inlet nozzle of a tire respectively at each end thereof.
