Abstract: The dual function bicycle air hand pump has functions of bicycle air pump and exerciser. The piston of the dual function bicycle air hand pump has installed a piston which has an off-center threaded canal, which can be closed either by a one-way valve threaded tube and or by a bolt. By simply exchanging the one-way valve threaded tube with a bolt and vice versa, the dual function bicycle air hand pump can be used as a bicycle air pump or an exerciser. When one-way valve threaded tube is used to close the off-center threaded canal of the piston the dual function bicycle air hand pump can be used as an air pump to pump air into a bicycle tire. When a bolt is used to close the off-center threaded canal the dual function bicycle air hand pump can be used as an exerciser for the training of muscles. It is very easy to exchange the one-way valve threaded tube with a bolt and vice versa.
