Nowadays, the most transportation on the road is electric vehicles, so we have to consider driving safety. It is very important to choose a good helmet at this time. How much is an electric helmet? How to distinguish between good and bad?
     1. EPS foam: The ratio of EPS in the entire helmet is the most important subject. EPS is generally divided into three colors: white, black, and gray. Among them, black and gray materials are imported raw materials.
     EPS has different weights. Each weight has different uses. We only talk about EPS for helmets. The one-piece molding is generally above 85 density. It can be regarded as safe. How to identify it? It may be difficult for professionals. Discrimination, generally by hand pinch method, after testing a little force to pinch EPS, EPS will not sag into it, if there is a depression, it proves that the density is not enough, if the depression is more serious, then it is best not to buy this helmet; many people will think The helmet is light and comfortable to wear. It is good. The lightweight helmet is very comfortable to bring, but it must be paid attention to the density, because the helmet with insufficient density is also very light, and the helmet with insufficient density is very unsafe. .
     2. Belt (webbing): How much is the electric helmet? Seeing the belt is also one of the factors that determine the value. The webbing is also a key accessory in the helmet and one of the main accessories of the helmet. The good quality webbing is generally fine and soft, and it feels good. The poor webbing is generally rough and hard, and the feel is not good at all. This kind of poor webbing will break off at the critical moment of danger, or it will be lifted and not elastic. The woven (bundle) belt is the main accessory for the head and helmet connection. It is very important, so be sure to pay attention when choosing a helmet.
     3. Adjustment (integral): The regulator is used to adjust and fix the helmet. It is also a key accessory. The regulator is plastic. Generally, it depends on whether it can withstand high temperature or low temperature. The belt of the regulator is the key place. If it is very hard or hard, it is very likely that it will not be able to withstand high temperatures or low temperatures, and it will break easily.
     4. Buckles, lining: These are the accessories of the helmet, the lining is generally not an important accessory, not much to talk about here. The buckle is also an important accessory, but it is difficult for non-professionals to distinguish between good and bad. This kind of accessory can only be tested by SGS test company. The famous helmet brand generally uses a good buckle because The brand is the brand. It is not like the brand of the cottage. In order to save costs and lower the price, some unqualified accessories are used.
     Friends, don't ask the electric car helmet how much this low-level problem, learn to know the goods is the king.
