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. Can the mobile phone riding software be used as a yard watch?

If the riding frequency is not high and the accuracy of the speed is not high, you can use your mobile phone to replace the bicycle codes, because now the mobile phone is also multi -star positioning, the accuracy should not be different from the low -end code table of the low -end code watch, and it will not be different.How many.If you are a friend who is often riding, it is recommended to buy a good -performing cycling code watch, because after all, the surgery industry has special attacks, the mobile phone speed is accurate, there is no coding, and the mileage and speed are biased.Moreover, the mobile phone weighs a lot. Under the condition of some ride conditions such as mountain roads and soil roads, it is easy to throw the mobile phone out and cause unnecessary losses.

2. Comparison of cycling code table and mobile phone code watch app

1. price comparison

The price of GPS code watch is a hundred yuan for many people, and the price of the flagship of the brand is sufficient to buy the Android flagship smartphone. When you have a powerful smartphone, you must not want to GPS codeSpend more money on the table.

However, with the emergence of more and more entry -level GPS giads, not only has strong functionality, but prices are no longer a problem.

2. battery life

Whether you use a gauge or a smartphone alternative code watch, the most unwilling to see is to remind you that "insufficient power".Generally speaking, the battery life of the code watch is longer than the mobile phone code app app.The official time is related to the function and screen brightness and other factors.

If you use a GPS code watch, it will greatly improve the battery life of your phone, because your phone does not need to drive a certain cycling app to consume your power. For the current peopleThe problem is not very big, the problem is very large.

If your cycling time is only 2-3 hours, then the smartphone is enough to cope with it, but if the longer riding time, it is recommended to equip a GPS code watch.

3. Screen and waterproof

Imagine whether your mobile phone's waterproof performance is passing on heavy rainy days, and the cycling watch takes into account the ride of heavy rainy days at the beginning of the design.There is also ride in strong sunlight. If you use smartphones, you need to mention high brightness to see the screen clearly, which reduces the battery life of your mobile phone. This GPS code watch is better.

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 are the benefits of bicycle codes?

The bicycle codes are electronic products used to calculate mileage and speed.There are two main functions of the code watch, monitoring and records.The former helps to understand itself during cycling, and the latter helps to analyze itself after exercise.bicycle gauge is generally used for the measurement of bicycle driving speed. The induction magnets installed on the steel bars installed on the front of the front car, the sensor on the front, along the connection line, the code watch seat on the grip and the code on the seatTable composition.The benefits of bicycle codes are: show several cycling data, such as current speed, cycling mileage, cycling time, etc., high -end code tables also have altitude, air pressure, slope display, and so on.

Second, the practical purpose of Bicycle code watch

1. record the total mileage of cycling

The most practical function of a bicycle gauge is the mileage of driving. This is how many kilometers have been ride on the day of your bicycle from the day of the bicycle.For example, you can know how long it has not been oil on the chain, how long hasn't it been maintained for Hua Gu and so on.We can also use the total mileage to set the mileage of bicycle maintenance. The normal bicycle has to be maintained once for 3,000 kilometers. We see that the total driving mileage is 3,000 kilometers to maintain it once.No need to remember time.

2. Display riding data

bicycle mileage is also very useful. It can clearly record the number of kilometers of your cycling, so that the bicycle riders can master the strength of the cycling.After you got back today, you found that you are tired, prove that you are riding too far.You see how many kilometers of the cycling cycling, appropriately reduced a few kilometers of cycling the next day.How far the ride is in your heart every day, and the cycle is getting tired.After exercise, it should be a relaxation of the whole body, a happy mood, and the excessive exercise will cause harm to itself.

3. The code watch shows the riding speed

The current speed display is also very important. It shows how many kilometers per hour you ride now. This can facilitate you to understand your riding speed. You can know your limit speed and maintenance speed.You can understand how long the distance you are going to ride today, and arrange other things.

4. Display time of bicycle code gauge

Time display is also very convenient, although there are many timing tools, such as mobile phones, watches, etc.However, it has its limitations. Now the large -screen mobile phones are put in the pocket of clothes when riding. When you take it out, you should not just support it. It is not convenient or safe.The watch worn on the wrist is okay in summer, and it is not convenient to ride in the long -sleeved season. A small code watch looks down and looks at the current time, saving trouble.

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.
