What misunderstandings are prone to appear when purchasing motorcycle Bluetooth helmets?

Carbon fiber helmets are safer than plastic helmets such as ABS

At present, most motorcycle Bluetooth helmets are made of ABS, glass fiber and carbon fiber. Among them, ABS helmets account for more than 90%. The process of glass fiber and carbon fiber is similar, and the mold can be used in general, but the process is complex, which leads to a very small proportion of FRP and carbon fiber helmets. In addition, carbon fiber materials are expensive, so the price of carbon fiber helmets is particularly high. Does that mean that carbon fiber helmets are safer than other motorcycle Bluetooth helmets?

This conclusion is a blind conclusion and a wrong understanding.

The main difference between ABS and fiber helmets is that ABS is easy to break under impact, and fiber helmets will break without breaking. In terms of material characteristics, carbon fiber material does have obvious advantages over ABS material. In addition, the helmet made of carbon fiber has a long production time cycle and high labor cost, so the output is small and does not match the market demand. Therefore, this material can not be popularized, so the price is high. This has also led many motorists to mistakenly believe that carbon fiber is safer.

For example, there are many helmets with helmet body models, including ABS helmets and carbon fiber helmets. Both helmets have passed the same certification. So is the carbon fiber helmet safer? The answer is No.

Under the same helmet body and the same certification, the characteristics of material will affect the weight of motorcycle Bluetooth helmet, but there is no experimental data to show the difference in the impact on safety. On the contrary, the processing technology, thickness, strength, EPS density and process design of materials can affect the safety of helmets.

However, it must be noted that the helmet with super low price should not be selected as far as possible, because it may be made of secondary recycled materials.

Myth 2: the more expensive the price, the safer it is

Many people say you can buy a motorcycle Bluetooth helmet as much as your head is worth. This reflects that many riders always judge the safety of helmets by the price of helmets, which may not be a correct conclusion.

For example, many Vintage helmets are very expensive. Do you think they are safer than some 300 yuan entry helmets? Not necessarily. But many people still choose this kind of high-value helmet. Why? Because in addition to the protection of the helmet, there is another function that everyone attaches great importance to, that is decoration. This makes some helmet manufacturers make an issue of "decoration" and appearance, so as to create very popular products and achieve success.

The high price of many motorcycle Bluetooth helmets is not due to the excellent safety, but depends on the R & D cost and manufacturing technology. Which do you think is safer?

At present, there is no relevant experimental data to show that because the helmet has real protective significance, it only plays a real role in 0.2ms-0.4ms in case of collision, and it makes an ornament and pre protection on your head the rest of the time.

So why is the price gap of motorcycle Bluetooth helmets so large? As I said just now, most of the time the helmet is used for decoration, so the manufacturer will do research on its comfort, aerodynamic design and its beauty. Research requires money, so the more complex the manufacturing process, the more exquisite the materials used, the finer the workmanship, and the more parts design and processes, it shows that the higher the cost, the higher the natural price.

For comfort, wear a larger size helmet

This misunderstanding can be said to be very common. And they know the size is big, they still choose to wear it, especially those stubborn and older riders. At this point, I hope the newly introduced riders will not continue to make mistakes.

Why do many people choose a larger helmet to wear? The main reason is that the inner liner of the helmet is generally designed to cling to and wrap the head, resulting in small space, poor air circulation and muggy. However, current helmets pay great attention to the design of front and rear air duct heat dissipation. When riding, the speed will gradually increase, the ventilation and heat dissipation of helmets will gradually reflect, and the muggy situation will be improved. Generally, you can adapt to it for a period of time, and you need to force yourself to adapt to this feeling when you just wear a full helmet.

Wearing a larger helmet has two very bad disadvantages. First, in an accident, it is easy to cause the helmet to fall off and lose its protective effect, just like not wearing it. In addition, we need to remind everyone that the helmet strap must be adjusted to the appropriate position, and ensure that the strap has been fastened when riding, otherwise it is also easy to cause the helmet to fall off and lose protection.

Secondly, according to foreign research, wearing a larger helmet is very easy to produce secondary collision injury during collision, aggravating the risk of concussion or brain injury. So please choose a helmet of appropriate size for your own safety.

Listen to others say that a brand is good, blindly follow the choice

Many car clubs have heard that a certain brand and helmet type are very good. In fact, for these car friends, they just unintentionally make their own comments in the circle. But many riders believe that this is the case. This leads to the spread of such remarks as conclusions when talking about helmet topics with others. This is a wrong understanding!
