How to choose a bicycle helmet?

Comment choisir son casque de vélo?

Wearing a bicycle helmet is essential for the safety of every cyclist, whether they are a casual rider or a seasoned competitor. A well-fitted and quality helmet can protect your head from injuries in case of an accident. However, choosing the right bicycle helmet can be challenging due to the variety of options available in the market. In this article, we will provide you with key elements to consider when choosing the bicycle helmet that suits your needs.

Size and Fit

The first criterion to consider when purchasing a bicycle helmet is size. Helmets are available in different sizes to fit the morphology of each cyclist. It is important to measure your head to know which helmet size fits you best. The measurement should be taken about 2.5 cm above the eyebrows, around the widest part of your head.

Once you have determined your helmet size, it is essential to adjust the helmet properly to ensure maximum protection in case of a fall. The helmet should be adjusted to sit flat on the head, with a slight pressure on the forehead and the top of the head. It should not move back and forth or from side to side.


Ventilation is also an important element to consider when choosing a bicycle helmet. Well-ventilated helmets allow air to circulate and keep your head cool during hot summer days. However, it is important to find a balance between ventilation and safety. Additional vents mean less material to protect your head, which can reduce safety.

Helmet Style

Bicycle helmets are available in a variety of styles, including aerodynamic helmets, mountain helmets, and road helmets. Each is designed to meet specific cycling needs. Aerodynamic helmets are designed for cyclists looking to improve their time in triathlon or time trial competitions. Mountain helmets are designed to provide extra protection for rugged terrain, while road helmets are designed for speed and lightness.


Weight is also a factor to consider when purchasing a bicycle helmet. Lightweight helmets are more comfortable and can be more aerodynamic. However, heavier helmets can offer extra protection in case of a fall.


Bicycle helmets must be certified by a recognized safety organization to ensure their effectiveness. The two main certifications are CE certification and CPSC certification. CE certified helmets meet European standards, while CPSC certified helmets meet American standards.


Finally, price is an important factor to consider when choosing a bicycle helmet. Helmet prices can vary considerably depending on quality, brand, and features. It is important to set a budget before starting your search to avoid spending more than you can afford.

However, it is important not to sacrifice quality to save money. A quality helmet can make the difference between a minor jolt and a serious injury in case of an accident. Therefore, it is better to invest in a quality helmet rather than choosing the cheapest one.

In conclusion, choosing the right bicycle helmet is crucial for the safety of the cyclist. It is important to consider size and fit, ventilation, helmet style, weight, certification, and price when purchasing a helmet. It is also important to find a helmet that you aesthetically like to encourage regular wear. Remember that wearing a bicycle helmet is the best way to protect your head in case of a fall and to stay safe on the road.
