If you’re looking for a mountain bike helmet that looks as good as it performs, consider looking for various style standpoint options and high-performance models in your favourite colour. While performance should always be your priority, many options available today let you choose a helmet that matches your style and personality.


The lighter a helmet is, the less fatigue you will feel when wearing it, which can make the biggest difference in comfort and performance on the trail. For example, while some mountain bike helmets can weigh more than a pound, you can find lightweight and comfortable models to wear all day long if your weight consciousness makes it difficult for you to wear some heavy helmets.


Another factor to consider when choosing a mountain bike helmet is whether you prefer a convertible helmet model that it can wear with or without goggles. It can be a great option for riders who like to wear sunglasses or goggles when biking and those who want the convenience of switching back and forth between gears.

Best Features of Mountain Bike (MTB) Helmets

Eyewear fit and goggle storage

One of the major features to be noticed is the integration of your eyewear and goggle strap adjustment into the helmet. It is important if you wear glasses or goggles while riding, as it helps to protect your eyewear from getting knocked loose or broken in the event of a crash while managing goggle pressure above your head.

Chin straps and buckles

Quality chin straps and buckles can help improve the performance and comfort of your mountain bike. Look for sturdy and durable ones that are easy to adjust and won’t loosen or come loose while you’re riding. The best mountain bike helmets also incorporate secure and adjustable quick-release cheek pads as added protective layer and chin guards to keep your helmet in place while riding.

Removable chin bar

If you’re looking for more protection, some models feature a removable chin bar that can be quickly and easily fastened or removed when needed. It is a great feature for riders who prefer to ride with or without the chin bar, depending on terrain and weather conditions. Other easy-to-remove features include pads, straps, and vents that can be removed for washing or to improve comfort.

Crash sensor

Some Mountain Bike Racing Helmets also incorporate a crash sensor that automatically alerts emergency contacts in the event of an accident. Many sensors are now integrated with GPS technology to pinpoint your exact location and notify emergency services if needed as the volume of crashes in MTB racing is increasing. 

Colours and graphics

Another consideration is the design and style of a mountain bike helmet. While many riders prefer to wear helmets in solid colours, like those of Troy Lee Designs, you can also find models with fun graphics and designs to help match your style.

MIPS, SPIN, and More

If you want the most protection possible, helmet For Impact Absorption technology for helmets helps reduce injury in the event of a crash. MIPS, or Multi-directional basic Impact Protection System, is a leading safety feature in many high-performance mountain bike helmets. This protection technology utilises an inner liner with low friction to reduce rotational impacts and brain protection against forces that may occur in certain accidents.


Another innovative safety feature in some mountain bike helmets is an in-moulded shell, which adds strength and stability to help reduce injury during a crash. Some models also include venting systems and breathable materials, which help keep your head cool and comfortable when riding in hot, along with various types of impact protection.

Light compatibility

Not only do many mountain bike helmets look great, but they are also compatible with lights to increase your safety on the trails. These lights can be securely attached to the helmet and often offer a bright, dependable beam of light to help you stay visible in dim or dark conditions.

Aftermarket mounts

If you frequently ride your mountain bike at night or want to camera-record your rides, look for helmets with built-in mounts to hold lights or action cameras. These mounts can be attached to any part of your helmet and adjusted for optimal positioning.

How much should I spend on a mountain bike helmet?

The price of a mountain bike helmet can vary widely, depending on the features you want and need. Basic models start at around $50, while high-end premium helmets can cost up to $300 or more. When choosing a helmet, look for something that offers great protection and comfort while also fitting within your budget.

If you are purchasing a helmet for regular use, it may be worth investing in a higher-quality model that will provide more protection and comfort over time. However, if you only use the helmet occasionally or your budget is tight, it is still possible to find models at lower price points that offer adequate protection and value.

When shopping, it is important to consider your individual needs and compare features, costs, and reviews to find the best helmet.

How are mountain bike helmets designed and tested?

Mountain bike helmets are typically designed and tested using a combination of advanced computer modelling, physical crash testing, and analysis of real-world accident data. Many helmet manufacturers have in-house testing facilities that test prototypes using computer simulations, followed by rigorous impact testing on actual human subjects.

In addition to the materials used and the helmet’s design, how a helmet is tested can vary greatly by manufacturer and country. For example, in Europe, helmets are often subjected to drop testing from various heights and on different impact surfaces. For example, the United States has no standardised test for mountain bike helmets. In Australia, helmets must undergo extensive impact testing, including dropping from up to 5 meters onto various surfaces.

Overall, a mountain bike helmet aims to provide maximum protection while being comfortable and lightweight enough for long rides. Considering the above factors, you can find the right helmet that offers safety and style on your next ride.
