When drive in a low speed, slightly pitch the upper part of the body, step steadily with the both feet, put the body weight on the flank footboard, and maintain the accelerator in a constant speed. When drive in a high speed, the elementary operation is the same; what is different is that in order to obtain balance and a bigger centrifugal force, the upper part's move must increase. While climbing upwards, the two feet must step on the footboard firmly, and accelerate before climbing. When climb a small angle hill, you must skid the body toward the seat front, and cause the center of gravity move ahead. You must stand on the footboard, curve the body, and cause the center of gravity to move to the front wheel. You must avoid shifting gears while climbing. If you must do this, please do it as soon as possible when the speed is invariable. When stop on the way of the hill climbing, you must hold the front wheel brake, and then hold the trailing wheel braking and the parking brake. Do the opposite when go downhill.
