Abstract: An air blowing and sounding handle bar socket connects onto the end of handle bars of bicycles and the like. A whistle inserted in the handle bar socket makes a pleasant sound when the handle bar socket is squeezed. Two semicircular air chambers are connected with a third chamber, and all of the three chambers supply compressed air for sounding the whistle when the handle bar socket is squeezed.

Abstract: A pedal which massages a user's foot having a rotating shaft and a plurality of crank shafts in the pedal body, offset portions of the said crank shafts act as cams to move a plurality of elongated cylinders above and below a face board of the pedal. The user steps on the pedals and mutually engaging gears installed on the rotating shaft and the crank shafts drive the crank shafts which in turn moves a plurality of the elongated cylinders in up-and-down displacements so as to apply massaging impact actions to an operator's soles.
