Wearing a helmet is essential for safeguarding cyclists from head injuries that can lead to severe consequences. Head Protection: Helmets serve as a vital barrier, reducing the impact of collisions and falls. Studies have shown that wearing a helmet reduces the risk of head injuries by 48% and serious head injuries by 60%. Traumatic Brain Injury Prevention: Traumatic brain injuries (TBIs) can have long-term consequences, and helmets help minimize these risks. A properly selected bicycle helmet is your primary defense against head injuries, which account for 75% of annual cycling-related fatalities. With the right helmet, not only can you safeguard your skull, but you can also enjoy the ride with comfort, style, and compliance with local laws.
Key Factors to Consider When Choosing a Bicycle Helmet
When it comes to choosing the right road bike helmet, prioritizing your safety and comfort on the road is crucial. Consider factors like fit, comfort, ventilation, weight, aerodynamics, additional safety features, and price to make an informed decision. The following sections break down these factors in detail to guide you through the selection process.
1. Fit and Comfort
The most crucial aspect of a road bike helmet is how well it fits your head. Look for helmets that offer a secure and comfortable fit. Consider the shape of your head and choose a helmet that matches it. Look for adjustable retention systems and sizing mechanisms that allow you to customize the fit. The helmet should sit level on your head, with the front edge just above your eyebrows. A properly fitting bicycle helmet should sit level and snug on your head without tilting forward or backward. The side straps should form a “V” shape just below your ears, and the chin strap should be tight enough that only one or two fingers can fit between the strap and your chin.
- Ensure the helmet fits snugly without being too tight.
- Adjust the straps to form a “V” shape under the ears.
- Check that the chin strap allows for slight movement but keeps the helmet secure.
2. Ventilation
The best road bike helmets offer safety, comfort, ventilation, and aerodynamic performance. Helmets feature a streamlined design with ample ventilation to keep the rider cool and comfortable during long rides. Generous vents on the outside and cut-in airflow channels on the inside keep your head cool. The Aries Spherical is another great all-rounder but with a primary focus on ventilation. It has best-in-class performance in independent safety tests, great airflow, and a comfortable fit.
- Look for helmets with multiple vents to enhance airflow.
- Consider models with internal channels Cyclingnews tested for ventilation performance.
- Ensure vents are strategically placed to avoid compromising safety.
3. Weight
Lightweight helmets tend to feel more comfortable, especially on long or challenging rides. Both material choices and design aspects contribute to weight savings. High-tech helmets will usually spare you a few grams by incorporating intricate internal bridges and supports that allow gaping vents but keep the helmet together in an impact. The best road bike helmets will be lightest in their given category, making them the most comfortable option because they place less strain on your neck. If you’re a competing cyclist, the other advantage of a lighter helmet is increasing your power-to-weight ratio; 50g might not make much difference to most of us mortals, but to a top professional looking for any marginal gain, it becomes significant.
- Opt for helmets with advanced materials like carbon fiber for reduced weight.
- Check the weight specifications provided by manufacturers.
- Balance weight with safety features to ensure protection isn’t compromised.
4. Aerodynamics
When you find road bike helmets, they are typically lightweight and aerodynamically shaped to minimize wind resistance and enhance the cyclist’s performance. The POC Procen Air was the fastest helmet in our Wind Tunnel tests. It’s a divisive-looking helmet for road racing, but if you care about speed above all else, this is the one to choose. With its short tail, the MET Codatronca has an advantage which makes it a more versatile time trial helmet for most riders. Riders will still get significant aero gains but without having to worry that they are always in a perfect optimum “turtle” position.
- Choose helmets designed for aerodynamic efficiency for racing or high-speed rides.
- Look for wind-tunnel-tested models for verified performance.
- Ensure aerodynamic designs don’t sacrifice ventilation or comfort.
5. Additional Safety Features
Most modern helmets come equipped with added safety technology like MIPS (Multi-directional Impact Protection System), WaveCel, SHIN (Shearing Pads Inside), Koroyd, and KinetiCore. Each of these technologies should help further reduce the forces transmitted to your brain from impacts and collisions in different ways, even if they cannot guarantee a better outcome in a specific situation. MIPS (Multi-Directional Impact Protection System) is a special liner that better protects your brain. It allows for the outer shell of the helmet to move independently of the inner shell in an impact. This action causes the twisting forces on the neck and skull to be minimized, lessening the impact to the brain.
- Prioritize helmets with MIPS or similar rotational impact protection systems.
- Check for certifications like CPSC, EN 1078, or NTA 8776 for e-bikes.
- Consider helmets with reflective elements for enhanced visibility.
6. Price and Value
We found no correlation between price and protection, with the highest-performing helmet being one of the less expensive, retailing at around ¡ê50. Despite the low price, the RCR helmet looks much more premium. It’s comfortable too, despite minimal padding. Helmets that meet safety requirements can be purchased for under $20. When considering the costs of providing helmets, agencies should consider the benefits. A NHTSA summary of helmet laws reported that “every dollar spent on bicycle helmets saves society $30 in indirect medical and other costs”.
- Compare helmets within your budget for the best safety-to-cost ratio.
- Look for discounts or crash-replacement policies from manufacturers.
- Avoid counterfeit helmets by purchasing from trusted retailers like REI.
Safety Standards and Certifications
All helmets sold must be certified to meet minimum safety requirements set by standards organizations. These standards are evaluated with testing on a pass/fail basis. However, not all helmets are created equal, and two helmets that meet the standard may offer different levels of impact protection. The U.S. Consumer Product Safety Commission (CPSC) mandates a series of tests covering peripheral vision, positional stability, dynamic strength of the retention system, and impact attenuation. In the Netherlands, an e-bike-specific helmet standard (NTA 8776) was adopted in 2017, designed around protecting against higher impact speeds and covering a slightly larger part of the head.
- Ensure the helmet meets CPSC, EN 1078, or NTA 8776 standards.
- Look for additional testing from independent labs like Virginia Tech.
- Verify certifications through the manufacturer’s documentation or packaging.

How to Properly Fit and Maintain Your Helmet
Regardless of the target audience, bicycle helmet promotions must include instruction on how to properly fit the helmet and the importance of wearing helmets on every trip. Every bicycle helmet must have instructions telling riders how to make sure the helmet fits properly and how to wear it properly. The instructions must include a picture showing the proper way to wear the helmet. If you crash and hit your head (or can’t remember for sure that you didn’t hit it), replace your helmet. That’s a must. A well-used bike helmet should be replaced about every five years and sooner if it’s damaged.
- Follow the manufacturer’s fitting instructions for a secure fit.
- Replace helmets after a crash or every five years, whichever comes first.
- Clean the helmet with mild soap and water to maintain its condition.
Frequently Asked Questions
How do I know if a helmet fits properly?
A properly fitting helmet should sit level on your head, covering your forehead about an inch above your eyebrows. The side straps should form a “V” under your ears, and the chin strap should be snug, allowing only one or two fingers to fit between it and your chin. Adjust the retention system for a secure, comfortable fit.
Do more expensive helmets offer better protection?
Not necessarily. Studies, such as those from Imperial College London, show no correlation between price and protection. Some affordable helmets, like those retailing around $50, perform as well as or better than pricier models in safety tests.
Can I use a helmet for multiple activities?
Helmets are designed for specific activities. A bicycle helmet may not provide adequate protection for skateboarding or skiing. Check the manufacturer’s labeling to ensure it’s suitable for your intended use.
