PROBLEM TO BE SOLVED: To provide a motorcycle with retractable wheels reducing the fatigue of a driver and preventing falling-down at the time of stopping, to ease excessive characteristic of traveling feeling change generated at switching to a retracting state or a supporting state, and to notify a driver of the state. SOLUTION: A driving motor mechanism with a worm wheel speed reducer and a supporting arm attached to a rotating shaft of a mounting base are transmitted by a toothed belt, and these are equipped at right and left of the motorcycle with retractable wheels. A operator selectively carries out retracting and supporting by a hand switch under a fixed speed, and need not make feet touch on the ground during stopping. A retractable wheel structure is equipped with a shock absorbing device. The excessive characteristic of the traveling feeling change at the time of switching retracting and supporting is eased, and each state of retracting, operating, and supporting is reported by an indicating lamp.
