1： Look at the appearance and the first feeling of the whole vehicle. The overall effect of the carriage, seat barrel and handlebar must be shown. People should not look at it. The appearance should conform to your aesthetics.

2： Look at the baking varnish to see whether the appearance is bright and bright, and whether there is a feeling of being covered.

3： Look at the workmanship to see whether it is seamless welding, whether the welding points are flat and smooth, whether the grinding is in place and whether there is desoldering.

4： Touch with your hand to see if the appearance is smooth and concave convex, and pay special attention to the dead corner; If it is not handled well, it will rust easily in a short time.

5： Check whether the front of the car is straight and whether it is high and low at the same time. Lift the bumper up by hand to see if there is a gap. It is normal. Hold the handle by hand and shake the front head to see if the gap is large and normal. The quality of the product can be confirmed by observing whether there is no scratch, thread leakage and rough workmanship.

6： It is very important to look at the large frame. We must look at the large frame and see whether all parts are welded in place, whether there is full welding, whether there is false welding, and whether the standard thickness of materials is used. See from below whether there is an overall balance.

7： Look at the product certificate. Before buying a car, you must look at the product certificate, whether the factory date and frame number are consistent with the car. In particular, the delivery date of electric tricycle battery is put forward, because it directly affects the vital interests of consumers; It is best to use the battery within 10 days.

8： Don't blindly pursue power. The greater the power of an electric tricycle of the same brand, the stronger the power, but the greater the battery loss. If it is not particularly needed, it is not recommended to buy high-power electric vehicles.

9： Pay attention to the test ride. When buying an electric tricycle, don't leave after paying the money. Be sure to carry out the test ride, especially the test ride after loading. How comfortable do you feel, whether it will be smooth, the tightness of the brake, whether each light will be on, whether the horn will sound, and so on.
