The pump (1) is designed to be mounted on the bottom strut of the back wheel and comprises a piston (2), arm (4), crankshaft (5), moving rod (6) and toothed wheel (7). A cylinder (11) is provided inside the pump casing, above which is an air outlet (12) and an air pressure gauge (9), and below which is a protective cover (14) and a thick tube (13), in whose base there is a round hole (15). A support bracket (21) for the piston rod (3) is positioned beneath the piston, which is attached to the rod by a pin (22). Once the piston rod has been secured the piston is placed inside the cylinder and the piston rod is secured beneath the cylinder.
