In recent years, with the continuous promotion of relevant departments, "wearing a helmet when riding an electric bicycle" has been widely known. But there are still some friends who have doubts, thinking that electric bicycles are not as fast as motorcycles, and wearing helmets is not an IQ taxOf course not, today let's talk about helmets. Helmets can really save lives
First of all, let's look at a few cases, a man riding an electric bicycle was in a traffic accident, hit his head on the ground, fortunately wearing a helmet, and his life was not in danger. 
*From Weibo Lanzhou public security traffic police also had a woman who was run over twice in a row by the wheels of a large truck, fortunately wearing a helmet, only slightly injured, if not wearing a helmet, the consequences are unimaginable. 
*From Weibo Observer.com There is another case that is not so lucky, there are two electric bicycles collided, two of them wearing helmets were intact, and the person without a helmet died of serious injuries because of his head hitting the ground. 
*From Weibo Traffic Management Bureau of the Ministry of Public Security, we can see from these casesWearing a helmet on an e-bike isn't a superfluous moveRather, it is an effective protective measure. So how should we choose the helmet correctly and use the helmet, let's talk about it in detail. Pick a helmet and look for these marks
Why do helmets protect us?Some friends may think that as long as the helmet is hard enough not to break their heads, this is actually only partly true. Because if the light is hard, the head is not cushioned in the helmet, and there is a collision, although the helmet is fine, but oursHitting our head on the inside of a helmet is no different from hitting a wall, so our brains can still be very bad**, resulting in injury or even death. Therefore, the helmet is not enough, it has to add a layer of buffer layer in the middle, in the case of a buffer layer, when the hard object hits our helmet, the buffer layer will be deformed to absorb energy, and the impact on our head will be much smaller, and it is less likely to be injured. Helmet structure compositionIn addition to the shell and cushioning layer, there are also components such as comfort padding, wearing devices, and goggles. Helmets are closely related to safety, and none of the components such as shells and buffers mentioned above can be sloppy, so many standards have been issued by countries for helmets. There is the "Motorcycle Occupant Helmet" (GB811-2010) (hereinafter referred to as the "old national standard"), as well as the mandatory national standard of "Motorcycle and Electric Bicycle Occupant Helmet" (GB811-2022) (hereinafter referred to as the "new national standard"), which will be implemented on July 1, 2023, as well as the most common 3C certification. In addition, there are some international certifications such as DOT, ECE, SHARP, and so on, but mainly for motorcycle helmets. Let's buy an electric bicycle helmetAs long as you look for the new and old national standards and 3C certification, children's helmets can also see 3C certification. 
Electric bicycle helmets can choose the new national standard Class A and Class B **Helmets that can meet the standards from the screenshot of e-commerce product introduction must pass various tests such as wear resistance, stiffness, stability of fixtures, strength of wearing devices, penetration resistance, collision energy absorption, etc., and qualified products can provide necessary protection for electric bicycle riders. How to choose a helmet?
If you open the shopping app and search for a helmet, it will definitely be difficult to choose on the spot, because there are so many types, so how do you choose a helmet exactly?First of all, it is recommended that you do not have to buy a motorcycle helmet. Because motorcycle helmet protection is indeed better, butFor an e-bike, the performance is a bit overflowingAfter all, according to the speed of 25km h of the new national standard electric bicycle, it cannot be compared with the speed of a motorcycle. And more powerful protection brings a heavier helmet at the same price, and the neck burden will be heavier, or some good motorcycle helmets can be lighter, but ** may be more expensive than our electric bicycles. Some race-grade motorcycle helmets tend to sacrifice some comfort for performance and are not suitable for everyday use. In addition, motorcycle helmets are usually thicker and heavier, and the protective area is larger, which will slightly affect the field of vision, and motorcycles must be equipped with rearview mirrors, which can make up for these problems, but electric bicycles often do not use rearview mirrors, which will bring some vision problems. Therefore, we can actually choose a special helmet for electric bicycles that meets the national standard, which is cheap, light and safe enough. Secondly, there is the helmet type. According to the new national standard, the shape of the helmet is divided into the following three types, with the protective ability decreasing from left to right, and the lightness and coolness increasing. 
Friends who commute and ride every day canChoose 3 4 half helmets or even 1 2 half helmetsAlthough the full helmet has better protective performance, the extra chin structure is more to avoid people falling out of the chin and facial injuries at higher speeds. Therefore, you can choose a lightweight, easy-to-wear helmet that won't be too stuffy in the summer. In addition, there is a kind of unmasked helmet, mainly a motorcycle helmet, which will not be repeated here. The size of the helmet is also very important. If you wear a small helmet on your big head, your head will be pinched and painful, like torture. The small head wears a large helmet, which is a little shaky, and once a collision occurs, the protective effect of the helmet will be affected. Therefore, when we buy a helmet, we must have the awareness of measuring the "head circumference", measure our head circumference, ask the store, and you can choose the right size helmet. There are also helmets that can adjust the head circumference within a certain range, and this type of helmet is also a good choice. The head shape is more extreme, and it is not easy to buy a hat for friends, you must choose the one-size-fits-all carefully. Finally, some other small accessories or something, you can choose your favorite one at will. 
***pixabayA good helmet should also be worn
Choosing a helmet is actually one step away, we have to wear it correctly in order to maximize our safety, specifically we have to pay attention to the following points:First of all, the helmet should be adjusted to the right angleThe front can protect the forehead, the back can protect the back of the head, the size adjustment should be appropriate, and the helmet will not shake or roll forward and backward after wearing. For those helmets that can adjust the head circumference, we can tighten the adjuster a little bit at the end. The second important thing is to be sure to fasten the buckle!Be sure to fasten the buckle!Be sure to fasten the buckle!Say the important thing three times. Some friends didn't know if it was to be handsome or troublesome, so they picked up their helmets and buckled them on their heads, and the buckle dangled under their necks and went on the road. If you wear a helmet like this, then the protective effect can only be said to be better than nothing, because in the event of a collision, the helmet may fly first and cannot effectively protect the head. The third thing is to adjust the tie properly, adjusting the tie too loosely will also reduce the protection effect. So is it better to tie it as tightly as possible?No, because tying it too tightly can compress the neck, make it difficult to breathe, and distract from it, and it's not safe. We can adjust the helmet straps, after buckling, one or two fingers can be inserted between the neck and the straps, and the tightness is more appropriate. In addition, it should be noted that the hard part of the lacing buckle should not be next to the mandible, but should be adjusted to touch the soft part of the neck, so that in case of a collision, it is not easy to hit the bone. Finally, the helmet is not like a legendary armor, which can be passed down to three generations, it has a service life, and the material will age after being exposed to the wind and sun, and the cushioning capacity will become poor, affecting safety. Hence usIt is necessary to look at the service life of the helmet and replace it in timeWearing an expired helmet will not have a protective effect. Planning and production
