We are developing a hyper small compact electric motor tricycle with six AA Batteries as source of power. Now, we concentrate on manufacturing driving part of it. In this study, while using gears, chain and sprockets, a transmission device was manufactured. And, we adopted bicycle as base vehicle and maxon DC motor 148866 as actuator. There, revolving speed of motor was controlled by PWD control using MOS-FET. Next, the running test was done in order to evaluate the quality of the vehicle. As a result, in the regular run on 3^<rd> gear, the average speed was 3.36 km/h and the running time was 32'00''till energy of the battery were all consumed. As a result, we got conclusion it was suitable when the moderating ratio is about 76 on the vehicle.
