Many new cyclists do not wear helmets and do not know how to choose a helmet. Even more extreme people think that those who wear helmets on their heads are fake. Today we are going to talk about why you should wear a helmet when you ride a bike. We are going to popularize the importance of wearing a helmet when you ride a bike. At the same time, we are going to help you choose a helmet that is suitable for you.

One, why wear a helmet?
Wearing a helmet during cycling will not only make you look professional and handsome, but more importantly, it can effectively protect our heads. Helmet’s head protection principle is similar to the bumper and anti-collision steel beam on a car. When the head is hit by an external impact, the helmet first helps you to block most of the impact energy, by sacrificing ourselves to preserve our head, as far as possible to reduce the degree of brain damage.

Second, what should we pay attention to when purchasing helmets?
We wear helmets when we ride, mainly for safety, secondly for comfort, but also for appearance level.
Then, the selection of cycling helmet focus, naturally is the three: safety, comfort, appearance.
When choosing, you should first choose the type according to your own use.

1. Structure forming process
Bicycle helmets are mainly composed of outer shell and foaming inner liner, which can be divided into integrated forming and non-integrated forming according to the production and forming process.
To put it simply, the integrated molding helmet is to put the PC shell with the blister and EPS into the mold for one-time stamping forming. The shell and foam are a whole without a gap, and the non-integrated helmet is to combine the molded EPS foam with the PVC shell by hand, and the gap between the shell and foam can be seen. A helmet with an integrated body will have a better fit between the shell and the liner, which will provide better head protection and a higher price.
2. Whether there is a skeleton inside
The top helmets use a skeleton in the inner helmet to increase the overall strength of the helmet, so that the inner helmet will not break and lose the leg and head protection during a strong impact. This technology used to be used for top helmets, but in recent years it has spread to other classes as the technology matures, so keep this parameter in mind when choosing a helmet.
3. Strengthen the structural design
It mainly refers to Mips, a multi-directional impact protection system. A yellow diaphragm placed inside the helmet can cushion the impact force from different directions and angles when the head is hit, reducing the impact intensity shock suffered by the brain and preventing more serious injury caused by spinal torsion.

Comfort level
The comfort of riding helmet is mainly reflected in the shape, weight, ventilation, lining and webbing.
1. Internal shape:
It is mainly divided into the Asian head type, which is slightly rounded, and the European head type, which is oval.
Many cyclists do not pay attention to the difference between 0 type and O type inside the bicycle helmet, which causes uncomfortable wearing of the helmet and mistakenly thinks that the helmet design is a problem. In fact, they do not choose the right one. The head shape of most people in European and American countries is type 0, while the head shape of Asian people is generally round. If you prefer the helmet of European and American brands or exported to Europe and the United States, you must pay attention to it. If the helmet is not suitable for a long time, there will be a strong sense of bondage.
2. Weight:
The weight of helmet will directly affect the feeling of wearing. A heavy helmet will increase neck pressure and cause neck pain when worn for a long time. Therefore, the lighter the weight of helmet, the better. But in order to pass the standard safety certification, the helmet design must not be too thin so most bike helmets weigh between 200 and 300 grams. There are few helmets on the market that can achieve less than 200g and guarantee safety, because this type of helmet has a great challenge to the design of the structure. If you see a particular helmet is very light, 200g or less, and it is not a well-known brand, then you should be alert to whether it is cutting corners!

3. Size
Different helmet brands, the specific size is not the same, basically are divided into S, M, L three sizes, we should pay attention to the adjustment range given by the manufacturer before buying, according to their own head circumference to choose.
4. Ventilation:
The more ventilation holes in the helmet, the better the ventilation, the cooler and more comfortable in the riding process. Of course, the more ventilation holes, the greater the wind resistance, so in order to reduce the wind resistance, there are not many ventilation holes in the helmet of road vehicles.
