When come up to Electric Fat Bike,we have a question,how to buy?The first is face. When you have determined a brand or a certain car model, the first thing is of course the appearance. The craftsmanship and level of the paint directly affect the first impression of this car. The paint materials include primer, top coat and varnish. Different brands of paint directly affect the final effect. Of course, we have no way to know the specific paint brand used in the car when choosing a car, but we can judge the quality of the paint based on the effect of the paint. A good baking paint has a transparent and bright surface, and the color is deep and natural. There should be no uneven color, chromatic aberration, and large areas of pitting or bumps. The applique process is flat and the paint is evenly covered. In the sun, the lacquer is bright and colorful, and the shade has a thick texture. If you find it difficult to understand these descriptions, the easiest way is to go to a few more stores and compare cars with the same color, and it feels like they will come out soon. The most important point is to consider the anti-ultraviolet ability of the paint. Many car models do not add anti-ultraviolet agents to the paint. After long-term exposure to the sun, the car will gradually fade, especially the white paint, which is more prone to fading or discoloration. Because such problems cannot be immediately judged, you can observe whether there is any fading problem in the show car of the car dealer and make a basic assessment.
Next is the lining. The structure of the whole vehicle is very simple. The basic units are the frame, plastic parts, shock absorption, battery, controller, and motor. The quality of the frame is particularly critical. Many users don't care about the quality of the frame because it is difficult to observe this part. However, the quality of the frame directly determines the safety performance of the entire vehicle. The following provides several ways to verify the frame. First observe the welding level of the frame in the vehicle plastic parts. If there is false welding or desoldering, the quality of the frame is not ideal. Secondly, observe whether there are traces of rust on the frame, because in order to prevent rust, the frame needs a process called electrophoresis. In order to control the cost, many frame manufacturers simply spray black paint without electrophoresis. If the new car is rusty The problem, that means the quality of the frame electrophoresis is abnormal. Finally, test the car, drive at high speed and brake hard to see if the frame shakes from side to side. If the shake is severe, it means that the frame quality is not good enough and there is a safety hazard. Because the electric vehicle market is mixed, the frame is hidden inside the vehicle and cannot be inspected directly. Therefore, many manufacturers do not strictly control the quality of the frame. Choosing a good frame is very important to the entire vehicle. There is also a simple method. If the battery is removed from the whole vehicle, you can lift up the weight for a test. The heavier the vehicle, the stronger the material and the greater the possibility of better safety performance.
