<p>PURPOSE: A bicycle with an air motor is provided to travel conveniently on the uphill road by operating the air motor with mounting an air tank and an air compressor, and to improve exercise effect corresponding to compressive force of the compressor by engaging a friction clutch in pedaling. CONSTITUTION: Air is charged in an air tank(1) by an air compressor in pedaling. A speed regulator(10) is adjusted by using air in the air tank when a bicycle is traveled on the uphill road, and an air motor is operated in discharging air from the air tank by opening an air regulating valve(3). The air compressor is operated to fill the air tank with air by a friction clutch adjusting grip(5) in pedaling or traveling on the downhill. A left handle bar is connected to front and rear wheel brake cables to operate brakes by a left hand, and the rear brake is operated before the front brake. The bicycle travels easily on the uphill road by operating the air motor.</p> |
