1. What is the material of the Bicycle helmet?

Bicycle helmets are usually made in the following materials:

1. Plastic:Plastic materials are light and durable, sobikeOne of the main materials for helmet production.Polycarbonate (PC) is one of the commonly used plastic materials. It has excellent impact resistance and can protect the rider's head from collision damage.

2. Bubble:bikeThe foam material in the helmet is mainly used to buffer and absorb collisions, reducing damage to the head of the cyclist.There are many types of foam, including polystyrene (EPS), polyurethane and polypropylene.

3. Cellulose:CellulosebikeThe helmet uses carbon fiber, glass fiber and other materials, which can provide higher strength and stiffness, which is lighter and high -grade than plastic helmet.

4, metal:somebikeThe helmet is made of metal, such as aluminum alloy and titanium alloy to provide higher strength and rigidity, but it is generally heavy.

bikeThe material of the helmet needs to have the characteristics of lightness, solidity, durability, and can effectively absorb and dissipate the collision power to protect the safety of the rider's head.

2. What is the role of a Bicycle helmet

1. Protect head safety

Wearing a helmet is the most basic means to ensure the safety of cycling, because the head is the most vulnerable part.The general Bicycle helmet is made of high -intensity materials, which can effectively disperse the impact of fragments such as rocks, earth and stones, and snowflakes to avoid severe damage to the head.

2,Reduce wind and noise

In some occasions, riding requires a higher speed, and its own breathing or wind sound will cause greater interference.Wearing a helmet can isolate a certain wind and other noise to create a more comfortable environment for your cycling.

3. Keep body temperature

In winter, wearing a helmet will play a warm role, promote the maintenance of body temperature, and make the experience during cycling more comfortable.

In short, wearing a helmet is the basis for ensuring the safety and health of cycling.Whether it is ride or occasionally ride, we should develop a good habit of wearing helmets, so that safety has become the bottom line of our cycling.
