Bicycle Helmets: Complete Guide to the Ideal Choice
The helmet is the most important accessory for anyone riding a bike. It’s not just a legal matter but personal safety: a good helmet can save your life in case of a fall or accident.
In this guide we will explain everything you need to know to choose the perfect helmet: from regulations to types, from technical features to practical advice.
Why the Helmet is Essential
Safety Numbers
According to international studies, wearing a helmet reduces the risk of serious head injuries by 70% in case of an accident. Despite this, many cyclists still do not use it regularly.
Even if not mandatory for adults during recreational use, wearing a helmet is always the right choice.
Regulations and Certifications: How to Recognize a Safe Helmet
CE EN 1078 Certification
All helmets sold in Europe must comply with the EN 1078 standard, which guarantees:
- Impact resistance
- Effectiveness of the retention system (strap)
- Adequate field of vision
- No dangerous edges
How to check: Look for the CE label inside the helmet referencing the EN 1078 standard.
Other Important Certifications
CPSC (USA): Very strict American standard
ASTM F1952 (USA): For BMX and downhill helmets
Snell B-95: Even stricter voluntary certification
Expert advice: A helmet with multiple certifications offers greater safety guarantees.

- Pass the tape over the ears
- Close the tape measure at the back of the head
- Read the measurement in centimeters
Standard Size Chart

- M 55-59 cm Adults (most common size)
- L 59-63 cm Adults large head
- XL 63-65 cm Adults very large head
Note: Sizes may vary between manufacturers. Always check the specific model’s size chart.
Technical Features to Consider
1. Adjustment System
Rear ring: Allows tightening or loosening the helmet for a perfect fit. The best systems are:
Dial fit system: micrometric adjustment with dial
Ratchet system: click adjustment
Boa system: precise adjustment with steel cable
2. Ventilation
More holes = better ventilation = more comfort in summer
Number of air vents:
- Urban helmets: 8-15 holes
- MTB helmets: 15-25 holes
- Road helmets: 20-30+ holes
Internal channels: Guide airflow to cool the head.
3. Weight
A lightweight helmet reduces neck fatigue:
- Urban: 250-350g
- MTB: 280-400g
- Road: 200-280g
- Children: 180-250g
4. Visor
Advantages:
- Protects from sun, rain, and branches
- Improves aerodynamics (MTB)
- Can be adjustable or removable
Disadvantages:
- May limit the field of vision
- Not always compatible with glasses
5. MIPS System
What it is: An inner layer that moves independently from the outer shell, reducing rotational forces in case of an oblique impact.
Is it worth it? Yes, if the budget allows. Increases safety by 10-15% according to independent studies.
Additional cost: +€20-40 compared to the standard version
How to Wear the Helmet Correctly
Positioning
- Height: The helmet should sit 2 fingers above the eyebrows
- Tilt: It should be horizontal, not tilted forward or backward
- Side straps: Form a "V" under the ear
- Chin strap: It should be tight but comfortable (allow 1-2 fingers)
Verification Test
- Shock test: Move your head forward/backward and right/left. The helmet should move with the head, not slip.
- Mouth test: Open your mouth. The helmet should press slightly on the head.
- Strap test: It must be tight enough not to slip over the chin.
Helmet Maintenance and Lifespan
- When to Replace the Helmet
Replace immediately if:
✅ You have had an impact or fall (even if no visible damage)
✅ There are cracks or breaks in the shell
✅ Retention system is damaged
✅ Padding is deteriorated
Replace after:
⏰ 3-5 years from purchase (even without falls)
⏰ Prolonged exposure to sun, heat, or chemicals
Why: Materials degrade over time, reducing effectiveness
Cleaning and Care
Every week:
- Clean the padding with a damp cloth
- Remove insects and dirt from the shell
Every month:
- Wash removable padding (if present) by hand with mild soap
- Check straps and buckles
Never:
❌ Using solvents or harsh cleaners
❌ Leaving the helmet in the car under the sun
❌ Hanging the helmet on the handlebar (it can fall)
Storage
- Store in a cool, dry place
- Avoid extreme temperatures
- Do not leave under direct sun for hours
- Use a protective bag for transport
Useful Helmet Accessories
1. Integrated or Clip-on LED Lights
Increase visibility in the evening and at night. Many modern helmets have mounts for rear lights.
2. Rainproof Helmet Cover
Protects from rain and keeps the head dry. Useful for commuters.
3. Technical Under-Helmet
- For winter: retains heat
- For summer: absorbs sweat
4. Sun Visor
- Clip-on or magnetic, protects from the sun without glasses.
5. Action Cam Mount
- GoPro Mount
