Please, don’t wear big ears and antlers on your riding helmet!

Do you wear a helmet when riding a motorcycle? Of course! How about riding a battery car? You have to wear it too! What about bicycles? This…

seems to be worn only during cross-country or competition? Actually not.

Compared with “iron clad meat” cars, “meat clad iron” bicycles, motorcycles and battery cars can hardly provide any protection for riders in case of accidents.

If there is no protective equipment, the great impact will directly affect the human body; If you wear inappropriate protective gear, the consequences may be even worse: it only increases the courage of the rider, but it does not provide adequate protection.

This is a push that can kill you: please wear a helmet and a suitable helmet when riding.

Wearing a lifesaving bicycle helmet.

Part of the bike author: Is Sophia safe to ride a bike? When riding in cities, the general speed is 10 to 15 kilometers per hour, and the speed of road bikes is about 20 kilometers per hour.

When going downhill and sprinting, the speed can soar to 50 to 70 kilometers per hour, which is equivalent to the speed of urban cars.

And objectively speaking, even if you ride slowly and don’t bump into others, others may bump into you when driving.

Cars have airbags and seat belts.

What about you? In 2020, the report of the Consumer Product Safety Commission of the United States showed that in non fatal riding accidents, one third of the injured were head injuries; In 80000 first-aid cases of riding related accidents, head injuries accounted for the main group.

In the crowded and high-speed cycling, it is often a big fall.

I had two relatively serious accidents on the bike.

One time, the downhill speed was out of control and hit a tree; Another time, he was knocked down by another rider and fell heavily on the ground.

In these two accidents, my head was obviously hit.

If I didn’t wear a helmet, the consequences would be unimaginable.

In the cycling circle, the novice and the ignorant are always fearless, and the more experienced the novice is, the more he is in awe of life.

Now when I see riders racing without helmets, I will catch up with them and tell them the importance of helmets.

Here, I also want to remind you that you must wear a helmet when riding a bicycle.

Adhere to the certification standards to select qualified life-saving helmets.

The simplest way is to see the certification.

You can find these marks on the instructions and certificates of the helmet.

See GB24429 certification for domestic helmets; European helmets see CE and EN1078 certification; North American helmets see CPSC certification; There are also more stringent TUV and SGS certification in Germany and Switzerland.

In addition, bicycle helmets also have a service life, not a lifetime helmet.

Even if the helmet is not damaged by collision, it will also have cracks that are hard to distinguish by the naked eye, and will also be damaged by wind, sun and sweat.

It is recommended to replace the bicycle helmet every 3 years.

In general, bicycle helmets can be divided into road bike helmets, mountain bike helmets, commuting and leisure helmets, and children’s helmets.

There are two kinds of road helmets.

One is portable, with many holes and good air permeability.

If there are many climbs on the cycling route, or you are prone to sweating, it is recommended to use a light road vehicle helmet.

The other is pneumatic, which is more aerodynamic, with almost no vents, and has little resistance when riding.

Therefore, this kind of helmet is mainly used in competitions to make riders ride faster.

There are three kinds of mountain bike helmets, namely, downhill helmet, cross-country helmet and endurance helmet.

Because mountain riding is more dangerous, these helmets can provide more protection and look more similar to motorcycle helmets.

Commuter leisure helmets usually have a brim to protect the eyes from the sun.

For most people who commute by bike in urban areas, this helmet is enough.

Children’s helmets are naturally for children, with small size and better protection for the back of the head.

One point that needs special attention: The Regulations for the Implementation of the Road Traffic Safety Law stipulates that only when you are 12 years old can you ride a bicycle on the road.

Children can ride bicycles in the community and park.

How to calculate that if you wear a helmet properly and have a suitable helmet, you must wear it correctly to play a protective role.

First of all, the front of the helmet should not be tilted up or down, but should be kept two fingers away from the eyes and flush with the eyebrows.

Many girls wear helmets to avoid bangs, so it is inappropriate to wear them on the side.

Secondly, be sure to fasten the chin strap to make room for two fingers under the strap and chin.

Finally, tighten the knob on the back of the helmet, and check it from time to time when riding to make the helmet fit the head comfortably and firmly.

The knob on the back of the bicycle helmet can fine tune the tightness of the helmet.

In Taobao screenshot, motorcycle helmets need more attention.

Author: Kedou is more dangerous than other common vehicles.

In all motorcycle traffic accidents, the death rate is as high as 59.6% [1].

In motorcycle accidents, head injury is the most common part, and almost all casualties have head injuries; Among the unfortunate dead, about 80% died of craniocerebral injury.

If the motorcycle collides with the obstacles in front at a speed of 40 kilometers per hour, it will produce an impact force of 2000 to 6000 kilograms – the human body can bear about 100 kilograms, and the rest needs a helmet to bear and cushion [2]; When the rider has head trauma, the helmet can even be used as a tool for pressure hemostasis.

Precautions for purchasing a life saving motorcycle helmet are as follows.

The same goes for identifying safety standards.

First, look at the safety certification standards.

Motorcycle helmets produced domestically shall conform to the national standard Motorcycle Crew Helmets; European helmets shall have ECE certification; American helmets shall have SNE certification; Japanese helmets need TIS certification..
