1. What is the difference between the Bicycle helmet and the electric car helmet

1. Different safety standards

In many areas, the helmets of battery cars and bicycles need to meet specific safety standards.Due to the faster driving speed of the battery car, the battery car helmet needs to meet more stringent safety standards to provide higher protection performance. Bicycle helmets only need to meet basic safety standards.

2. Different structures and materials

The battery car helmet is relatively strong and impactful, the Bicycle helmet is lighter, the structure is thin, and it is more suitable for low -speed cycling.

2. Can the Bicycle helmet be used as an electric vehicle helmet?

Bicycle helmets can be used as electric vehicle helmets, but from the perspective of safety, electric vehicles are still equipped with specialized electric vehicle helmets.The electric car helmet uses the hard helmet and plastic mask of the foam in the ABS shell, which has stronger collision resistance and safer.The Bicycle helmet is a all -in -one helmet made of foaming materials. The streamlined design has a lot of breathable design and lightweight. It mainly considers comfort and heat dissipation and breathable performance.Therefore, for the sake of safety, it is recommended to wear an electric car helmet.

Bicycle helmet is a common head safety protection equipment. The main function is to reduce the damage to the head of accidental collisions and minimize the damage to the minimum.It avoids fragile and most important heads by scattered and buffer impact.But don't think that you can bump wildly when wearing a helmet. It can only reduce the damage and not completely avoid damage.The reason for wearing a helmet is simple and important, to protect the head and reduce damage.

1. Is the Bicycle helmet in one -time?

Bicycle helmets can be used multiple times under normal use and proper maintenance, and provide long -term head protection for cyclists.

Although the Bicycle helmet is not disposable, after being severely impacted or damaged, it should be stopped and replaced with a new helmet.After the helmet is impacted, its internal structure and material may have been invisible, and it will no longer provide sufficient protection.

2. How long is the shelf life of Bicycle helmets generally

For the use time of the Bicycle helmet, many riders think that the life of the helmet depends on when it is broken or broken, and then discard it.So will there be hidden safety hazards after a certain period of use of the Bicycle helmet?How many years can the helmet do not collide?

Generally speaking, the Bicycle helmet is valid, because the helmet is exposed to sunlight, calories and other elements for a long time.In addition, the helmet will inevitably fall when used, which will damage the internal structure of the helmet.

The general recommendation of some brand helmet manufacturers is to replace the Bicycle helmet once in three to five years, mainly because the Bicycle helmet needs to face various complex conditions for outdoor products, such as high temperature, ultraviolet rays, deep cold, drought climate, and humid climate.Seasons, temperature, sweat, etc. The materials that constitute our helmets will be degraded over time, which cannot meet its test standards. Therefore, it is difficult to protect the safety of the head after three to five years.

The materials used in the Bicycle helmet are all shattered materials when they are hit. When the head hit hard objects, the helmet will absorb a certain impact and cause rupture to achieve the role of protecting the head.After any collision, replace the old helmet in time to ensure its best performance.

It is worth noting that whether or not you fall or collide, it is recommended to change the Bicycle helmet once as possible in three to five years.Although the helmet has not collided, the sun exposure and sweat erosion can make the helmet and accessories aging, thereby weakening the protection performance of the helmet. No matter how expensive the helmet is, it is not as expensive than the head of the head.

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.

1. Is the wind mirror of the helmet?

When buying a cycling helmet, the helmet with a wind mirror is a good choice.Wind resistance and windproofness are important indicators to evaluate the safety performance of the helmet, and the helmet with wind resistance design can better resist the airflow when the bicycle is driving and reduce wind resistance and wind noise.This can increase your cycling experience while providing better security protection.

The cycling helmet in the wind mirror not only has better windproof performance, but also has more convenience and practicality.For example, some wind -resistant helmets are often equipped with detachable wind resistance baffle or wind resistance mirror, which can better protect the vision during cycling.However, when buying a Bicycle helmet with a wind mirror, you need to pay attention to the following points:

1. Wind resistance performance:When buying, you need to pay attention to the helmet's good wind resistance performance, which can effectively resist the airflow of bicycles when driving.You can view the certification logo and test report of the helmet to understand the evaluation results of its wind resistance.

2. Adaptability:Bicycle helmet with a wind mirror needs to be paired with your Bicycle helmet to ensure that the helmet can closely fit the head to prevent wind and sand from invading.When buying, you can try to wear a helmet to check its fit and comfort.

3. clean and maintenance of the lens:The helmet with good wind resistance is generally equipped with a detachable windshield or a wind barrier mirror. It is necessary to pay attention to its cleaning and maintenance.If the surface of the baffle or goggles is dirty or scratched, it will affect the windproof performance, so it needs to be cleaned or replaced in time.

In short, when buying a cycling helmet, you can choose a helmet with wind resistance design to better protect yourself.It is necessary to pay attention to its certification signs, adaptability, lens cleaning and maintenance to ensure that it can effectively provide security protection.

2. Is the wind mirror riding helmet suitable for wearing glasses?

Wind mirror cycling helmet can be suitable for people wearing glasses, but you need to choose the appropriate model and size. It is recommended to choose built -in glasses racks and open -designed wind mirror cyclists.

As we all know, riding helmets is usually relatively close, and people with glasses are easy to feel uncomfortable.The design of the wind mirror cycling helmet is usually relatively loose, and the person wearing glasses will be more comfortable to bring the helmet.Therefore, for people wearing glasses, wind mirror riding helmets are a good choice.Of course, it is also important to choose the appropriate wind mirror riding helmet model and size.How to choose a wind mirror riding helmet suitable for wearing glasses?

First of all, you need to pay attention to the wind mirror riding helmet of the built -in glasses rack.This kind of helmet usually sets a glasses rack internally to fix the glasses to avoid shaking during cycling.Secondly, you need to choose an open -designed wind lens helmet.The lower jaw part of the open helmet is relatively loose, which can adapt to different facial shape and glasses size, and it is more suitable for people with glasses.In addition, you need to choose the appropriate wind lens helmet size according to the size of the head circumference to ensure that the helmet pastes the head, so that it will not blur the sight or cause excessive eye pressure.

In short, if you are a rider wearing glasses, choose the appropriate wind lens helmet to ensure safety and comfort.Finally, don't forget to choose a standard helmet and wear it in a prescribed manner to ensure cycling safety!
