How to buy a good electric car
muah! Xiao Bian came to class again. With the popularity of electric vehicles and to improve the performance of electric vehicles, as well as increased gasoline prices and other factors, more and more people choose to buy electric cars. Today Xiaobian teaches us how to buy a favorite electric car! There is a lot of knowledge in buying a good electric car. We are here to gradually discuss the face and the inside. Let's talk about "face" first. The so-called "face" is, of course, something on the facade. When you identify a brand or a car, the first thing, of course, is the appearance. The craft and level of paint directly affect the first-time feeling of this car. Materials used for baking paints include primers, topcoats, and varnish. Different brands of paint directly affect the final results. Of course, when we choose a car, we have no way to know the specific brand of paint used by the vehicle, but we can judge the quality of the paint according to the effect of the paint. Good paint, bright light on the surface, deep and natural color, there should be no color unevenness, color difference and large areas of pockmarks or bumps. If you find it difficult to understand these descriptions, the easiest way is to go more than a few stores. The contrast of the same color of the car models will soon come out. (These are actually the same as buying other cars. Which color of paint is good and which is not good). There is also the most important point is to consider the anti-ultraviolet ability of paint, many car paint paint does not add anti-ultraviolet agents, the car after a long period of exposure to the sun will fade, especially white paint, more prone to fading or discoloration problems, small During the compilation, white and other colored cars are often noticed, and it is found that white cars are particularly susceptible to fading or discoloration. Such problems cannot be judged immediately. It is possible to observe whether there are fading problems in the cars of the dealers and to make a basic assessment. Followed by Li Zi, "Li Zi" certainly refers to the quality of the car, starting from the car's architecture, parts, and processes. The structure of the vehicle is very simple, the basic unit is the frame, plastic parts, shock absorbers, batteries, controllers, motors. The quality of the frame is particularly critical, and many users do not care much about the quality of the frame, because this part is difficult to observe. However, the quality of the frame directly determines the safety performance of the vehicle. The following provides several ways to verify the frame. First of all, observe the welding level of the frame inside the vehicle's plastic parts. If there are false welding and desoldering, the quality of the frame is not ideal. Second, observe whether the frame has rust marks, because the frame needs a process called electrophoresis in order to prevent rust. Many frame manufacturers simply spray black paint without electrophoresis to control the cost, if the new car is rusty The problem is that there is an abnormality in the electrophoresis quality of the frame. (Insert a point here, try to choose a better brand when choosing a car at the beginning, so that the quality of the car will be more assured) The final test, high-speed driving and then emergency braking, to see if the frame appears to shake, if shake It is very powerful, indicating that the quality of the frame is not closed and there are safety hazards. Because the electric vehicle market is mixed and the frame is hidden inside the vehicle, it cannot be checked directly. Therefore, many manufacturers do not strictly control the frame quality. Selecting a good frame is very important for the vehicle. There is also a simple method, if the vehicle removes the battery, you can lift the weight, and the heavier it means that the more solid the material used in the vehicle, the greater the possibility of better safety performance. With respect to weight, the heavier the car is, the more reliable it is because the heavier the car is, the more solid it is, the more impact-resistant it is, and the more stable it is. If you think that Xiaobian's article is useful, please give Xiaobian a compliment or leave a message to support Xiaobian. If you have any suggestions for Xiaobian, it is also convenient for you to leave a message. muah! (Text / Chen Guotu) A bicycle lock is a security device used to deter bicycle theft, generally by fastening the bicycle to a fixed object, e.g., a bike rack.
An inherent challenge to bicycle theft prevention is wheels and bicycle seats (seatpost fastener) with a quick-release lever, making them detachable from the frame (on most but the most economical of bicycles). Unless both wheels and frame are secured, wheels can be removed separately. An optimal locking method will secure the frame as well as both wheels - either to a fixed object or to each other.
Locking devices vary in size and security; the most secure tending to be the largest, heaviest and least portable. Lesser EQUIPMENT is used to deter attempts by less skilled and determined thieves. Thus like other security equipment, bicycle locks must compromise between security, portability and cost. Some are made of particularly expensive materials chosen for their acceptable strength and low density.

An alternate defense is the provision of bicycle lockers or a bike cage in which the whole bicycle is locked, but these are rare and uncommon in most countries. A bike locker is not a bicycle lock.
