Brands engage in fierce competition to develop the finest bicycle helmets. The intense rivalry drives continuous innovation in the quest for the best road helmet, commuter helmet, or aerodynamic racing helmet. 

When deciding on a purchase, factors like comfort, aerodynamics, and breathability all play a significant role in your considerations.

Bike Helmet

Safety, without a doubt, is of utmost importance. I have personally tested numerous helmets that offer additional protection, notably the Multi-directional Impact Protection System (MIPS). Presently, over 120 brands worldwide utilize this system. 

It is worth mentioning that certain brands, such as Lazer, employ their own technology to address rotational impacts. Virginia Tech, an independent testing organization, consistently ranks helmets with MIPS highly in terms of safety, making it a feature worth considering.

To assist you in making an informed decision, my guide will cover all the essential aspects of how to choose a bike helmet. So, without further ado, let us commence the process. 

What is a Bicycle Helmet

Bike Helmet

A bicycle helmet is a protective headgear designed specifically for cyclists. It is worn on the head and serves to minimize the risk of head injuries during bicycle rides or accidents. 

Bike helmets typically consist of a hard outer shell made of polycarbonate or similar materials and a foam inner lining, often made of expanded polystyrene (EPS), which provides impact absorption. 

The shell helps to distribute the force of an impact, while the foam lining cushions and absorbs the energy to protect the head.

The primary purpose of a bicycle helmet is to reduce the risk of head injuries, such as concussions, skull fractures, or traumatic brain injuries, in the event of a fall, collision, or other accidents while cycling. 

Wearing a properly fitted helmet is highly recommended for cyclists of all ages and skill levels, as it significantly improves safety and can potentially save lives.

Safety And Security Tips

Bike helmets are an essential piece of safety equipment for anyone who rides a bicycle. They are proven to reduce the risk of head injury by up to 85%, and can even save lives.

Studies have shown that wearing a helmet is the single most effective way to prevent head injuries while cycling. In fact, a study by the National Highway Traffic Safety Administration found that cyclists who wore helmets were 45% less likely to be injured in a crash than those who did not wear helmets.

Helmets work by absorbing the impact of a fall or collision, which can help prevent skull fractures, brain damage, and even death. They are also relatively inexpensive and easy to find, so there is no excuse for not wearing one.

Here are some additional reasons to wear a bike helmet:

  • It sets a good example for children and other cyclists.
  • It can help you to feel more confident and comfortable while riding.
  • It is required by law in many states and municipalities.

So next time you go for a bike ride, make sure to wear a helmet. It is the smart thing to do, and it could save your life.

Factors to Consider when Choosing a Bicycle Helmet

When choosing a bicycle helmet, there are several important factors to consider to ensure you select the right one for your needs. Here are some key factors to consider:

1. Helmet Fit and Retention System

Above all else, for a helmet to be effective in the unfortunate event of a crash, it must remain securely on your head. Similar to footwear, helmets vary in fit across different brands, making it crucial to try them on before making a purchase.

Most helmets employ a dial-based retention system (such as Giro’s Roc Loc 5 or Kask’s Octo Fit) to fine-tune the fit. However, it’s important to note that the vertical adjustment range—the positioning of the rear adjustment supports on your head—differs among helmets, so this is an aspect worth considering.

Equally significant are adjustable and comfortable straps. They should be able to be fastened snugly under your chin, ensuring maximum effectiveness.

2. Comfort

Comfort is also a crucial aspect to consider when selecting a bicycle helmet, especially if you spend extended periods cycling. I agree head sizes and shapes vary among riders, but certain design elements contribute to the overall comfort of a helmet, regardless of the user.

The design of the padding, adjustability of the full circumference headband, and the chinstrap design all contribute significantly to the comfort of a helmet. Adequate padding in the forehead and temple areas is particularly important since most headband adjustment systems on helmets tighten in the back and push the head against the front of the helmet. 

During testing, I found that the location, coverage, and shape of the padding and foam liner were more important than the thickness of the padding itself.

The most comfortable internal headband systems form a complete loop around the head, ensuring a secure and comfortable fit. Some helmets only have a partial circle around the head and anchor into the helmet liner near the temples, which tends to be less comfortable.

The design of the chinstrap also plays a significant role in bicycle helmet comfort. Helmets incorporating thinner webbing straps and a Y-buckle are preferred by me since they allow the straps to lie flat against the face, enhancing overall comfort.

By considering these comfort factors, you can select a bicycle helmet that provides a comfortable fit for your head shape and ensures a pleasant riding experience, even during long days in the saddle.

3. Material

The majority of bicycle helmets are primarily constructed using expanded polystyrene (EPS) foam as their core material. This foam structure serves as the foundation and is then covered, to varying extents, with a rigid polycarbonate shell (and occasionally a touch of carbon fiber) to enhance durability and safeguard the EPS foam from accidental impacts and scratches.

This fundamental design has remained unchanged for many years. However, emerging manufacturing techniques and materials, such as 3D-printed Polyamide 11 or other proprietary polymers, are now starting to make their way into the market.

Manufacturers naturally assert that these alternative designs offer advantages over traditional bicycle helmets. Nonetheless, whether these purported benefits truly manifest during real-world use is yet to be determined.

4. Aerodynamics

In today’s cycling landscape, the aerodynamic trend seems to be influencing every aspect, resulting in higher costs and rendering your current gear seem outdated. However, when it comes to helmets, embracing aerodynamics may indeed be sensible. 

The potential energy savings achieved with aerodynamic helmets should not be underestimated, particularly if your focus is on achieving high speeds.

Of course, there are trade-offs to consider. Enhancing aerodynamic efficiency often entails sacrificing ventilation holes or accepting unconventional bicycle helmet shapes that, to be honest, can sometimes appear rather eccentric. Nevertheless, if your primary objective is to ride faster, the importance of aesthetics might take a back seat.

5. Safety Certifications

Look for helmets that meet recognized safety certifications. In the United States, the Consumer Product Safety Commission (CPSC) certification is the most common and ensures that the bicycle helmet meets minimum safety standards. 

Additionally, certifications like EN1078 (European standard) or AS/NZS 2063 (Australian and New Zealand standard) indicate that the helmet has passed specific safety tests.

6. Ventilation

Optimal airflow within a bicycle helmet is crucial for maintaining a cool head, consequently regulating your body temperature as a whole. Ventilation plays a vital role in enhancing both the comfort and performance of a helmet. 

Interestingly, the number of vents alone does not determine the quality of ventilation. Certain helmets strategically position vents and incorporate internal channeling to ensure optimal airflow. It is worth noting that in some helmets, the presence of an inner MIPS liner may obstruct certain air vents. 

However, the finest MIPS helmets are designed with MIPS liners that align with the helmet’s vents, allowing for uninterrupted airflow.

7. Adjustability

Superior helmets employ a chinstrap system that fastens under the chin and splits into two straps in front and behind the ear, where they connect to the helmet. Typically, a plastic Y-buckle joins these straps just below the ear. In many helmets, the Y-buckle allows for adjustments of the straps both in front and behind the ear. 

Helmets equipped with an adjustable Y-buckle generally receive better ratings in terms of adjustability. Nevertheless, certain helmets lacking an adjustable Y-buckle still manage to accommodate a wide range of head shapes and sizes.

Most helmets also feature an adjustable dial located near the back, allowing you to tighten or loosen the headband of the helmet. While these tension dials usually function as intended, some may be more challenging to manipulate, especially when wearing gloves or dealing with cold hands.

By paying attention to these adjustability-related factors, you can select a bicycle helmet that ensures both comfort and security, enabling it to stay securely in place during your rides while providing the protection you need.

8. Visor

A visor is a small brim or shield attached to the front of the helmet. It helps to shade your eyes from sunlight, rain, or debris, providing better visibility and comfort. Visors are particularly useful for mountain biking or commuting in various weather conditions. Some helmets come with removable visors, allowing you to customize your bicycle helmet based on your preference or riding style.

9. Weight

The weight of a bicycle helmet can have an impact on its comfort, especially considering the strain it places on your neck. In certain cycling disciplines, weight becomes a more significant consideration. 

Opting for a lightweight helmet means reducing the burden on your neck muscles. Additionally, a lighter helmet can provide an advantage during climbs by minimizing the extra grams that could potentially slow you down. 

However, it is important to note that as a bicycle helmet becomes lighter, there is a trade-off in terms of reduced material available to protect your head in the event of a crash. More material generally translates to increased protection. 

Road bike helmets, known for their lightweight nature, tend to offer less overall protection compared to mountain bike helmets, which prioritize better coverage and therefore tend to be heavier. Full-face helmets, which provide the most comprehensive coverage, offer the highest level of protection but are also the heaviest due to their extensive coverage area.

10. Shock Absorption Technology

Opinions regarding the optimal bicycle helmet technology for head protection still vary to some extent. However, the consensus among most researchers is that rotational forces, which often result in concussions and other significant injuries, pose the greatest risk. 

In response to this concern, the prevailing technology utilized today is the multi-directional impact protection system (MIPS). This innovative system aims to mitigate rotational forces during accidents by allowing the helmet’s outer shell to slide slightly upon impact. 

MIPS technology has gained significant popularity and is incorporated into bicycle helmet models offered by numerous manufacturers. Additionally, there are alternative designs on the market, such as POC’s SPIN pads and Bontrager’s Wavecel liner, both of which aim to reduce rotational forces through different mechanisms, such as compression. 

Note: A detailed discussion of these technologies is done down below in the article. 

11. Use Case

Bicycles serve diverse purposes, ranging from commuting to downhill mountain biking, and helmet manufacturers produce helmets specifically designed for these different scenarios. 

While it is perfectly fine to wear a mountain bike helmet during your commute, it might include additional features like a visor or a chin guard that may not be necessary or worth the extra cost. It is advisable to seek a bicycle helmet that aligns with your intended use of the bike, ensuring that you choose one that best suits your needs.

12. Durability

The EPS foam commonly used in bicycle helmet liners is a relatively soft material that is susceptible to dents and abrasions. Helmets with the highest durability feature a shell that extends around the base of the foam liner, providing comprehensive coverage and minimizing the exposure of the liner to potential dents and impacts. 

Such helmets tend to sustain less damage during regular daily use. However, the inclusion of this full-wrap shell for added durability also contributes to the overall weight of the helmet.

Regardless of their construction quality, most bike helmets are designed to effectively function for a single impact only. Therefore, if you experience a crash where your helmet makes contact with an object, it is crucial to replace it to ensure continued safety. 

Some bicycle helmet manufacturers even offer crash replacement programs to encourage users not to continue wearing a compromised bicycle helmet that may not provide sufficient protection in subsequent incidents.

13. Types of Bicycle Helmets

Bike helmets come in various types, each designed for specific types of cycling and rider preferences. Here are some common types of bike helmets:

Road Bike Helmets

Road Bike Helmet

Helmets specifically designed for road cycling are typically characterized by their lightweight construction and superior ventilation. These helmets are tailored to meet the specific requirements of road cyclists, often prioritizing weight reduction and breathability over enhanced protection. 

As road accidents typically involve a lower likelihood of colliding with objects after falling off the bike, these helmets may provide less coverage at the back of the head compared to some other bicycle helmet types. 

Additionally, road bike helmets typically do not feature an integrated visor. This distinction is largely based on tradition, serving as a visual indicator to differentiate between road helmets and those intended for mountain biking. Consequently, road cyclists often opt to wear a cycling cap underneath their helmets to shield their eyes from the sun, compensating for the absence of a visor.

Mountain Bike Helmets

Mountain Bike Helmet

In comparison to road bike helmets, mountain bike helmets generally offer enhanced protection. They feature extended coverage at the back of the head, acknowledging the higher likelihood of falls and accidents in mountain biking. 

As a result, mountain bike helmets provide more substantial overall protection compared to their road counterparts. However, this increased protection comes at the cost of added weight. Additionally, due to the additional material required for enhanced protection, mountain bike helmets have the potential to offer slightly less ventilation than road helmets.

Full Face Helmets

Full Face Bike Helmet

Full-face bike helmets, also known as downhill helmets, bear a resemblance to motorcycle helmets and are specifically engineered for high-speed riding comparable to motorcycle speeds. These helmets prioritize protection as their foremost objective. 

Offering complete coverage, they encompass the entire head, including the chin region, ensuring comprehensive safeguarding in the event of a face-first impact. Due to the extensive coverage and added material required, full-face helmets tend to be the heaviest among bicycle helmet styles. 

Additionally, as they are primarily designed for activities that involve less pedaling, they have the potential to generate more heat, making them potentially warmer to wear during use.

Skate Helmets

Bike Helmet- Skate helmet

Skate helmets are designed to provide coverage to the top and back of your head, resembling the helmets commonly worn for activities like roller skating or skateboarding. Compared to other bicycle helmet types, skate helmets typically exhibit a heavier weight and offer less ventilation. 

However, their appearance is less sport-oriented, making them an excellent choice for bike commuters who prefer a more casual and non-competitive cyclist aesthetic.

Kids’ Helmet

Bike Helmet for Kids

Helmets designed for children are tailored to meet the needs of younger riders. These helmets place emphasis on comfort, proper fit, and age-appropriate safety features. Typically, kids’ helmets incorporate additional padding and adjustable sizing systems to ensure a secure and comfortable fit. 

Moreover, they often showcase vibrant colors or engaging designs, aiming to make the helmets visually appealing and captivating for children.

14. Style and Aesthetics

Although not directly linked to safety, the style and aesthetics of a bicycle helmet can hold significance for many riders. Opting for a visually pleasing bicycle helmet can contribute to an enhanced biking experience. 

Helmets are available in a variety of designs, colors, and finishes, catering to diverse preferences. It is important to prioritize safety features and fit the above style alone. However, discovering a bicycle helmet that aligns with your personal style can bring an additional element of enjoyment to your rides.

A Detailed Explanation of Trending Bicycle Helmet Safety Technologies


MIPS is a widely used bicycle helmet safety technology designed to reduce rotational forces on the brain during angled impacts. It consists of a low-friction liner inside the helmet that allows for a small amount of movement between the outer shell and the head. 

In the event of an impact, this movement helps to redirect and absorb rotational energy, reducing the risk of brain injuries. MIPS technology is commonly found in helmets for cycling, skiing, and other high-impact sports.

2. Specialized ANGi

Specialized ANGi is an innovative helmet technology that combines impact detection and emergency notification capabilities. ANGi includes a small sensor and accelerometer integrated into the helmet, which measures both linear and rotational forces during impacts. 

If a significant impact is detected, ANGi can automatically send an alert to your emergency contacts, providing them with your GPS location. This feature adds an extra layer of safety, especially for solo riders who may encounter accidents during their activities.

3. Smith Koroyd

Smith Koroyd is a helmet safety technology that utilizes a unique honeycomb-like structure to provide improved impact protection. It consists of numerous co-polymer tubes bonded together to form a lightweight and breathable core inside the helmet. 

During an impact, these tubes compress, crumple, and deform, effectively absorbing and dissipating energy from different angles. This technology helps to reduce the risk of injuries caused by linear and rotational forces, providing enhanced protection for the head.

4. Bontrager Wavecel

Bontrager Wavecel is a helmet safety technology that focuses on reducing the occurrence and severity of concussions. It involves the use of a proprietary cellular structure called Wavecel, which is integrated into the helmet’s construction. 

The Wavecel material is designed to flex, crumple, and glide during impacts, effectively absorbing and redirecting the forces away from the head. This technology claims to be up to 48 times more effective at preventing concussions compared to standard EPS foam helmets, providing a higher level of safety for cyclists.

It’s important to note that these technologies are constantly evolving and improving, with new advancements being made in bicycle helmet safety. When choosing a helmet, it’s recommended to consider the specific requirements of your activity and ensure that the helmet meets relevant safety standards.

How to Adjust a Bicycle Helmet Properly

To begin, start by adjusting the tightness of the helmet. Many helmets sold feature an adjustment wheel that can be fully opened to place the bicycle helmet on your head and then twisted to achieve a snug fit. (Keep in mind that fit systems may vary, as some helmets utilize interchangeable interior foam pads for adjusting fit snugness.)

Next, buckle the chin strap and ensure it is tightened properly. The straps should form a comfortable V shape as they rest beneath each ear. (If the straps don’t form a comfortable V, adjust the buckle beneath each ear until they do.)

Finally, with the chin strap securely buckled, open your mouth wide. As you do so, the helmet should exert gentle pressure on the top of your head. If it doesn’t, tighten the strap slightly and repeat the process. (Avoid overtightening the strap to the point of discomfort.)

Additional Bicycle Helmet Fit Tips From Experts

Sizing can vary among different bicycle helmet brands, so it is important to verify the head circumference indicated for the specific size you are considering. Just like shoes, helmet molds can also have brand-specific shapes. Therefore, it is advisable to try on helmets at a store to determine which brand fits your head shape best.

If you find yourself between sizes, it is generally recommended to choose the smaller size. Alternatively, you can explore other bicycle helmet models or enhance the fit of a larger helmet by wearing a cycling cap or beanie. In some cases, adults with smaller heads may find that a kid’s size fits them comfortably.

A properly fitting bicycle helmet should feel snug without being excessively tight. It should sit level on your head without tilting back, and the front edge should be positioned one inch or less above your eyebrows to ensure proper forehead protection. 

Test the fit by gently pushing the helmet from side to side and front to back. If it shifts noticeably by one inch or more, adjustments are needed to achieve an optimal fit.

Effective Bicycle Helmet Care Suggestions

When it comes to cleaning a helmet, it is advisable to refrain from using chemical solvents. Manufacturers typically recommend using a soft cloth or sponge, along with mild soap and water. In the case of removable pads, they can be washed separately.

It is crucial to avoid storing a bicycle helmet in areas such as attics, garages, or car trunks where heat can build up. Excessive heat exposure may result in the formation of bubbles on the helmet parts. It is essential not to wear a helmet that has been damaged by heat.

Loaners should be wary of lending their bicycle helmet to others. It is important to have knowledge of the specific usage and history of your own helmet throughout its lifespan.

What size bike helmet do I need?

To determine the right size of a bike helmet, begin by measuring your head circumference, as helmet sizing is based on this factor.

To measure your head circumference, use a flexible tape measure and wrap it around the widest part of your head—approximately one inch above your eyebrows. Alternatively, you can use a string to encircle your head and then measure its length with a yardstick.

Here are the general bike helmet size chart parameters for bike helmet sizing:

  • Extra small: below 20″ (51cm)
  • Small: 20″–21.75″ (51cm–55cm)
  • Medium: 21.75″–23.25″ (55cm–59cm)
  • Large: 23.25″–24.75″ (59cm–63cm)
  • Extra large: above 24.75″ (63cm)
  • One size fits all: features a highly adjustable fit system

When to Replace a Bicycle Helmet

It is vital to understand that bike helmets for adults are intended to absorb a single impact. Therefore, it is crucial to consider any helmet involved in an accident as damaged, even if its appearance seems unaffected. In such cases, it is recommended to replace the helmet with a new one.

Furthermore, regardless of whether you have experienced any crashes or not, it is advisable to replace your bicycle helmet after five years. Factors such as pollution, exposure to UV light, and general weathering can gradually weaken essential components of the helmet over time. By replacing the bicycle helmet every five years, you ensure that it remains in optimal condition and provides reliable protection.

How to Choose a Bike Helmet — Frequently Asked Questions

Is there an e-bike-specific bicycle helmet?

The Netherlands stands as the sole country with a dedicated bicycle helmet standard for e-bikes, which was implemented in 2017. Known as NTA 8776, this standard focuses on safeguarding against higher impact speeds and offers coverage over a slightly larger area of the head.

In the United States, there are presently no helmet regulations specifically tailored to e-bike usage. However, certain manufacturers like Specialized and Smith offer commuter helmets that adhere to the NTA 8776 standard, despite the absence of mandatory requirements.

Should a road bike helmet feature padding?

Certainly. Padding serves the dual purpose of enhancing comfort and effectively absorbing sweat from your head. An optimal design for a road bike helmet will include padding that can be easily detached for washing and replacement. 

Different helmets for bicycles may feature varying styles and thicknesses of padding, so it is advisable to try on several models to determine which ones suit you best.

Is a lighter road bike helmet better?

Like most cycling gear, the price of road bike helmets often increases as their weight decreases. The top-performing road bike helmets tend to be the lightest in their respective categories, providing enhanced comfort by reducing strain on your neck.

For competitive cyclists, a lighter bicycle helmet offers the additional benefit of improving the power-to-weight ratio. While a difference of 50g may not matter much to most cyclists, it can be significant for elite professionals who are constantly seeking marginal gains to enhance their performance.  



I am a passionate, adventurous cyclist and my biking philosophy is to have fun, I felt the need to share my knowledge and learn more about bikes. I always ensure I adhere to all road rules. I hope that you will give biking a try. It’s a great way to get fit and have fun.
