A bicycle helmet is essential equipment to ensure your safety while cycling. Given the wide variety of models available, it's crucial to select a helmet suited to your riding style, your head shape, and your personal preferences. This buyer's guide will help you make the best choice by taking into account the fundamental criteria.
The different types of bicycle helmets
Road helmets
Designed for road cyclists, these helmets are lightweight and well-ventilated, offering optimal comfort on long rides. Their aerodynamic design reduces air resistance, thus improving performance.
MTB helmets
Designed for mountain bikers, these helmets offer increased protection, particularly at the back of the head. They are often equipped with a visor to protect against the sun and mud spray.
Urban helmets
Ideal for getting around town, these helmets prioritize comfort and style. They often feature a simple design and may incorporate reflective elements for better visibility.
Full-face helmets
Primarily used in downhill (DH) or BMX, these helmets cover the entire head and face, offering maximum protection during risky activities.
The essential criteria for choosing a bicycle helmet
Size and fit
A properly fitted cycling helmet is essential for effective protection. Measure your head circumference and refer to the manufacturer's size guide. The helmet should be comfortable without being too tight, and remain stable without shifting during sudden movements.
Ventilation
Good ventilation helps regulate temperature and prevent the buildup of perspiration. Road helmets generally have numerous vents, while urban helmets have fewer, but with optimized ventilation channels.
The weight
A lightweight helmet reduces fatigue on long rides. Road helmets are often lighter than MTB or urban models, but it's essential to find a balance between lightness and protection.
Safety standards
Make sure the helmet meets current safety standards, such as the European standard EN 1078. This certification guarantees that the helmet has passed rigorous impact and resistance tests.

Advanced protection technologies
Some technologies offer additional protection:
- MIPS (Multi-directional Impact Protection System): reduces rotational forces in the event of an oblique impact.
- WaveCel: honeycomb structure absorbing impact energy.
- SPIN (Shearing Pad INside): silicone pads reducing rotational forces.
Additional features to consider
The visor
Useful for protecting the eyes from the sun, rain or debris, the visor is often found on MTB helmets and some urban helmets.
adjustment systems
A good adjustment system allows you to precisely fit the helmet to your head. The adjustment dials at the back offer quick and easy fitting.
Reflective elements
To improve your visibility, especially in urban areas or during night rides, choose helmets with reflective strips or integrated LEDs.
Compatibility with accessories
Some helmets are compatible with accessories such as glasses, action cameras or rain helmet covers.
Comparison of helmet types according to the activity
| helmet type | Practical | Main features |
|---|---|---|
| Road Helmet | Road cycling | Lightweight, ventilated, aerodynamic |
| MTB Helmet | Mountain bike | Enhanced protection, visor, extended back cover |
| Urban Helmet | Getting around town | Comfortable, understated design, reflective elements |
| Full-face Helmet | Downhill, BMX | Full head and face protection |
Tips for helmet maintenance and replacement
Cleaning
Clean your helmet regularly with lukewarm water and mild soap. Avoid solvents or harsh chemicals that could damage the materials.
Storage
Store the helmet in a dry place, away from direct sunlight and extreme temperatures, to preserve its protective properties.
Replacement
It is recommended to replace your helmet every 3 to 5 years, even if it hasn't sustained an impact, due to material wear. After a significant impact, replace it immediately, even if no visible damage is apparent.
FAQ
How can I tell if my helmet is the right size?
Measure your head circumference and compare it with the manufacturer's size guide. The helmet should fit snugly, without pressure points, and stay in place when you move your head.
What is the lifespan of a bicycle helmet ?
A helmet should be replaced every 3 to 5 years, even without impact, to ensure optimal protection. After an impact, replace it immediately.
What is the difference between a MIPS helmet and a classic helmet ?
MIPS helmets incorporate technology that reduces rotational forces during an oblique impact, providing additional protection against head injuries.
Can I use a road cycling helmet for MTB ?
Although possible, it is preferable to use a helmet specifically designed for MTB , offering better coverage and a visor to protect against debris.
How do I clean the inner foam of my helmet ?
Remove the foam if it is removable and wash it by hand with warm water and mild soap. Let it air dry before replacing it.
