As an aspiring, responsible, passionate and knowledgeable sports bike enthusiast, you should understand the importance of wearing helmets when riding a bike (I won't say that I will wear helmets when riding a bike to dinner for some time). You should also wear a helmet when riding a road bike or mountain bike.

But when it comes to wearing helmets when riding an electric vehicle, as a cyclist with ideals, responsibilities, passion and knowledge, you and your family may have the demand for electric vehicle travel. I think you must popularize the knowledge of wearing helmets correctly to them with a sense of responsibility. Then you may want to buy helmets of appropriate size for all families and teach them how to wear them hand in hand.

In this process, I think you and more riders will be at a loss: you will find that the use scenarios of sports bikes and electric bikes are similar, but there are also huge differences.

1. Bicycle helmets can be used as Electric vehicle helmet Use?

The level of impact required for sports bicycle helmets is not low. The most famous case is an accident in 2007: a guy named Ryan Lipscomb was run over from head by a big truck. The helmet was cracked but not broken, and his head was intact. This is not only an excellent promotion for GIRO, you should also believe that most qualified sports bike helmets can do this.

In contrast, the current national standard speed limit for electric vehicles is only 25km/h, and most of the previous speed limits are also within 40km/h. It is very common to exceed this speed when riding on roads, and mountain bikes need to deal with sharp objects that may exist in the forest environment. Therefore, in terms of safety requirements, sports bicycle helmets need to deal with greater potential dangers than the current electric bicycle riding environment. It seems that there is no problem to ride an electric bicycle directly with sports bicycle helmets.

But there is a problem.

For a long time last year, I went to work by electric bike. I didn't buy a special helmet at that time, but I just picked up the Bontramer Ballista for riding a road bike. It's very comfortable, breathable, and safe. In fact, it's very good. The only problem is

This helmet costs more than 1000 yuan, which is worth a cheaper electric car. You can't hang it on the handle of an electric car parked at the roadside, in case someone goes along and makes you feel distressed for a long time. Besides, this helmet doesn't have its own goggles. You also need to wear riding glasses - well, you can buy two electric cars with helmet and glasses. Whether you ride a bike to work, buy vegetables, pick up children from school or board a giant robot to save the earth, you have to take these two things in hand.

Of course, this is a special case, but most sports bicycle helmets will face the same problem: most of these helmets do not have goggles, which is not convenient for shielding against wind and rain; Colorful and with a large number of vents - too innovative in the eyes of older people; Both have two tying systems: the back of the head and the lower jaw. The back of the head is especially important, but many people can't adjust it at all - you will carefully adjust the tying behind the head before every ride, but your family may not, but if you don't adjust it properly, the helmet will be useless; The price is high, which will form an additional psychological burden when parking and staying

The core reason for the two wrong demonstrations is that the posterior cerebral fasciculus system is not adjusted correctly. The core reason for the two wrong demonstrations is that the posterior cerebral fasciculus system is not adjusted correctly

Well, considering that there are really two or three hundred yuan in the market (in most people's eyes, it is expensive to juice), the color is relatively plain, the air vents are relatively few, and the products with goggles are also available. If your family is willing to learn to use the dual beam system and can really learn it, these helmets may have certain advantages in use compared with the so-called electric vehicle helmets at the same price: lighter weight, more ventilation, and better vision.

Why do you say that? Let's try to discuss

2. Is the current electric vehicle helmet suitable for electric vehicles?

First of all, I don't know the national standard of electric vehicle helmets, but from my personal point of view based on practical functions, most of the current electric vehicle helmets may not be suitable for the current national standard electric vehicles. They are more like moped helmets.

This is really... typical. This is really... typical

If you look at these helmets, they usually have less air vents, cover that extends to the back of the neck (so quite a few products do not have a back of the head bunching system), and they have their own goggles that can rotate upward, and they are very heavy: generally, the products are 700g up, and a recently purchased product of a well-known brand even marked a full weight of 940g.

Very heavy, brother... many road helmets are 180g... very heavy, brother... many road helmets are 180g

The self wearing goggles and the simplified back of the head binding system reduce the learning cost and reduce the probability of wearing these helmets inappropriately; Due to the relatively upright riding posture of ordinary electric vehicles, the heavier helmets are barely acceptable - although the extra weight may increase the chance of whiplash injury in the cervical spine when an accident occurs, after all, it is not the neck burden of road vehicles, which is one gram for five grams; However, the ventilation capacity may be a problem for the current new national standard models.

The ventilation capacity is insufficient, and most bicycle helmets will not have this problem, because bicycle helmets have many vents; Motorcycle helmets, even full helmets, do not have this problem, because motorcycles are fast. But electric vehicles are not as fast as motorcycles, and the number of helmet vents is not as large as bicycle helmets, which is very embarrassing.

If you have worn some large aerodynamic helmets, such as Ballista, Evade and Attack, you will find that these helmets need a relatively fixed depression angle to enter the wind, and they need to reach a certain speed to have sufficient ventilation. When I used the Evade generation before, my experience was that the speed needed at least 30-35km/h, and Ballista was still cool when it was slower. Now, my question is: how much ventilation can these "electric vehicle helmets" with fewer air vents have at the maximum speed of 25km/h - OK, I'll give you an extension to 35km/h -? Don't forget that bicycle pneumatic helmets have rear air outlets, while electric vehicle helmets have closed back heads.

I'm not very optimistic, especially when summer is coming

In addition, the new national standard models do not have such a large storage space in the car, and your helmet also faces the dilemma of having nowhere to put when parking. In a word, I think these "electric vehicle helmets" on the market may not be so suitable for the actual use needs of the new national standard electric vehicle products.
