1. The lighter the helmet, the better.

Relatively speaking, the helmet should be as light as possible. But the lighter it is,Bicycle helmetThe fewer opportunities it has to pass the national security certification tests, the higher the relative price will be. Therefore, the prerequisite for choosing a helmet is passing the national security certification tests. Most helmets priced above 200 yuan achieve a weight of around 260G, which won’t make you feel tired even during long trips. So there’s no need to worry too much about the helmet’s weight metrics. Unless you are doingbicycleCompetition. Try to reduce your weight, otherwise it’s not worth spending extra money on ultra-lightweight helmets.

2. The larger or more numerous the holes in the helmet, the more air permeability it has

Air permeability is crucial for a helmet, ensuring your head stays dry during long rides. The more or larger the ventilation holes on the helmet, the stronger the airflow around your head, and you will feel cooler. However, remember that the more or larger the ventilation holes, the more exposed your head is, and thus the level of protection decreases accordingly.Road cyclinghelmet andMountain bikeCompared to helmets, they have more or larger ventilation holes. Similarly,Mountain bikeHands, but road cyclists must also consider the weight of helmets. Generally speaking, the lighter the helmet, the more expensive it is. Therefore, unless you are doing so...Bicycle RaceTry to reduce your weight as much as possible; otherwise, it’s not worth spending extra money on a ultra-lightweight bicycle helmet.

3. The small clasp and strap are crucial for functionality; if they cannot withstand a certain force, they will break.

People may only know that cycling helmets need to pass impact tests, but the buckles and straps also require corresponding tensile tests. If they fail these tests, they cannot be used on helmets. Therefore, a qualified cycling helmet—including its small buckles and straps—must pass the relevant tests in order to truly meet national safety certification standards.

4. Helmets cracked or used beyond the expiration date

If there is a crack, do not use it. Wearing it provides only emotional comfort and has little practical benefit. Minor bumps and scratches are not a problem, but once there is a serious fall due to strong force, it may not offer any protective effect. Don’t underestimate a crack—it alreadyPhysical StructureThe force and component forces on the helmet have been changed. Do you know why a bridge in Seoul in the 90s collapsed? It is later inferred that it might be due to a weak weld at one side of the bridge deck, which caused cracks. If we replace this with a simple principle: if you pull a brand-new A4 paper from both ends, it may take some effort to tear it apart, but once a small hole is made in the middle, it becomes very easy to break the paper.

Whether or not the rider has fallen or been hit, they should replace their cycling helmet every three years. This is because, even if the helmet has not been hit, exposure to sunlight and sweat erosion can also damage it and some parts of it.Accessoriesaging, thereby weakeningSafety factor, damages the helmet’s protective performance.

5. Wearing a helmet without a strap

The jaw strap for removing the helmet may provide greater comfort, but if your head is hit, it will easily fly off, and thus cannot offer any protection. Therefore, to maximize the protective effect of the helmet, please fasten the jaw strap at all times.

6. Wearing helmets that are too wide or too narrow

If the helmet size is incorrect, it will not protect your head from impacts. Do not make the mistake of buying a helmet that does not fit properly. To determine the correct size, measure around the largest part of your head (usually 1 cm above the eyebrows) and purchase the helmet based on this measurement. Since helmets often come in small, medium, and large sizes, you may only be able to get a size that is relatively suitable. Then, use the adjustment knob to rotate the button until the most comfortable size is achieved. After wearing the helmet, turn it from one side to the other and from the front to the back to check if it fits comfortably. If it is too loose or too tight, further adjustment or replacement may be necessary.

7. Using inferior helmets: In China, helmets do not require certification

The production of helmets follows strict technical standards. Inferior helmets often fail to meet safety collision protection requirements, which can be dangerous. Many car owners may not know how to determine whether the helmet they purchase is safe. In fact, simply checking whether the helmet has a CE certification label is not sufficient to determine its safety; additional verification is required.Test Reportand certification documents. The CE mark certification is a certification specific to individual products, focusing on the safety characteristics of the product. It is a compliance certification that indicates whether the product meets the requirements for public safety, hygiene, environment, and personal safety.

So in China, do cycling helmets not need any certification? The answer is no. Before 2009, there was no complete standard for the safety of cycling helmets in our country. It was drafted jointly by CrossSpeed Helmets Co., Ltd. and some other companies under the title “Safety Requirements and Testing Methods for Sports Helmets, Bicycles, Skates, and Roller Sports Helmets”. This standard was officially implemented in 2010, and since then, different versions of national standards have emerged.

However, in China, most helmets are still produced according to the CE EN1078 standard. Since many Chinese helmet manufacturers focus on exports, the helmets available in the Chinese market are basically certified under CE EN1078. Some helmets may display the CE mark, but they have not actually undergone certification by TUV or SGS. For each product and different size, there should be corresponding test reports and certification documents—consumers must pay close attention to this. Helmets without safety certification are dangerous.

Therefore, helmets circulating in the Chinese market must have a CE label, along with corresponding testing reports and certification documents to be considered truly qualified helmets.

8. Incorrect wearing position

The most effective position for wearing a helmet requires keeping the helmet and head level, with the edge of the helmet approximately 1 cm above the eyebrows. If this position is not correct, check whether the helmet size is appropriate, then adjust the adjustment knob and chin strap to ensure the helmet is worn in the right place.

9. Laces are loose

The loose straps allow the helmet to move and bounce at any time, especially when there is a collision against the headSecond collisionAs a result, the protection effectiveness decreases. Therefore, it is necessary to adjust the length of the strap so that the distance between the strap and the chin is set to a gap of one finger, which can maximize the effective safety protection performance of the helmet.

10. Place the cycling helmet back in place after use

After each use, store the cycling helmet in a cool and well-ventilated place to prevent it from being exposed to high temperatures or prolonged sunlight.^[3]
