The life-saving function of bicycle helmets is beyond doubt. According to a report by the U.S. Highway Safety Insurance Research: in 1999, 98% of bicycle fatalities in the U.S. were not wearing helmets, and those who wore helmets during collisions had an 85% reduced risk of severe head injuries. With the increase of hard asphalt roads and stone roads, head injuries from cycling accidents have also risen. Cycling helmets provide essential protection for the vulnerable head, making them a must-have for riders.
Generally, those who haven’t been in an accident won’t understand the importance of good gear. Many people feel insecure and think those who wear high-end gear are just showing off, but that’s not true. When falling at the same speed, we obviously want the strongest protection possible—life is only once. Saving money on gear means spending more in the hospital. Even the most minor fracture surgery now costs nearly ten thousand yuan. Cutting costs here is truly not worth it. Let’s take a look at the seven key features for evaluating helmet quality.
[Material]— High Density
Helmets are typically made from foam materials (standard or high-density, the difference lying in their impact resistance) and have a smooth outer shell.
[Weight]— Lightweight
Whatever rests on your head shouldn’t be too heavy, which is why cycling helmets aren’t made from alloy materials. Most helmets weigh between 9–16 ounces, even lighter in pounds. Note: Cheap helmets are usually heavier.
[Inner Lining]— Washable
Features like washable corduroy fabric or antimicrobial padding help keep your helmet clean and comfortable to wear. Well-made helmets have larger, higher-quality linings that adhere more firmly to the inside of the helmet. The Velcro on the back of the lining allows for easy cleaning—just soak it in water with detergent or dish soap for a few minutes, gently rub it, rinse it clean, and let it dry.
[Comfort]— Adjustable Fit
Cheap helmets are generally uncomfortable. A snug fit is essential. Bike shop helmets come in small, medium, large, and extended sizes, while cheaper ones might only be one-size-fits-all. Remember, a comfortable helmet greatly reduces pressure on the rider’s head and neck and maximizes protection upon impact.
[Ventilation]— Keeps You Dry
Ensures your head stays dry during long rides. The more vents a helmet has, the better airflow around your head, and the cooler you’ll feel. Cheap helmets have very few vents, so they get hot. But keep in mind, more vents mean more exposed head area, reducing protection. In hot weather, wear a “sweatband” on your head to prevent sweat from dripping into your eyes. In cold seasons, use “ear covers” or elastic thin scarves (called balaklavas) inside for warmth.
[Type]— Meets Cycling Needs
Half-shell cycling helmets come in road-specific (no visor), or dual-use road/mountain (with removable visors). Some riders use baseball or rollerblading-style helmets. Full-face helmets resemble motorcycle helmets, often used by downhill or dirt jump cyclists. So, the type you choose also determines the helmet’s price to some extent.
[Design]— User-Friendly
Helmets come in different types. Some have plastic visors to protect glasses from sun glare or rain. Visored helmets offer sun protection, and reflective stickers can prevent nighttime collisions. The brighter the color at night, the easier it is for cars or other cyclists to see you. (PS: Don’t think bright colors are just showing off.)
Besides the above factors affecting helmet price, there are also research and development intellectual property costs, marketing expenses, brand premiums, and more. Value for money isn’t one-size-fits-all—at least in the helmet industry, the technical requirements are very high, making it much more honest than luxury brands like LV.
In summary, when choosing a bicycle helmet, prioritize one that fits your needs and is reasonably priced, but follow this selection priority: comfort > ventilation > appearance > weight.
How often should you replace a helmet?
The purpose of a helmet is to break—it’s meant to do so. The materials used in helmets are designed to shatter or crack upon sudden impact, such as when your head hits something. That’s how a helmet protects your head. It’s built to withstand at least one impact. After any collision, replace the old helmet promptly to ensure optimal performance.
Note: Regardless of whether you’ve fallen or collided, cyclists should replace their helmets every three years. Even without impact, prolonged sun exposure and sweat can degrade the helmet and its components, reducing safety and protective performance.
No matter the price, your cycling helmet must fit tightly.
Some Tips:
1. If your helmet comes with instructions, read them carefully before use.
2. Avoid using chemical agents to clean your helmet. The manufacturer recommends using a soft cloth or sponge with some soapy water.
3. Do not store in attics, garages, trunks, or other high-temperature environments. Excessive heat can cause the foam lining to bubble excessively. Do not wear a helmet that has been damaged by heat.
4. Do not lend your helmet to others. You must be aware of how your helmet is used and ensure it remains in good condition after each use.
