A Complete Guide to The Best Mountain Bike Helmets [STARTER GUIDE]

Mountain biking is a dangerous yet exciting sport that comes with a lot of risks. The pinnacle of these risks is brain injury. This is the major reason why riders – both novice and experts – should invest in a high-quality mountain bike helmet. Regular bike helmets are not ideal as they cannot provide the necessary protection in case of a gnarly fall.

There is a wide range of trail helmet models that come with lots of safety features and the latest advancements in design. Mountain bike helmets also vary in weight, coverage, ventilation, and comfort. They are designed with the mountain bike rider in mind.

The price tags of these mountain bike helmets may be intimidating, but then the damage to your brain and head – in case you are in a gnarly crash – far outweighs the financial costs. Personal safety is worth any investment, so you shouldn’t be too frugal.

Mountain Bike Helmet Features

Not all mountain bicycle helmets are the same. They come with the following specific features:

Detachable Visor

What differentiates mountain bike helmets from other road-biking models is the addition of visors and their greater head protection or coverage. Visors help to keep the sun out of your eyes and also provide additional protection from low-hanging branches and rain.

Visors are also shaped differently; some visors are long and narrow while others could be short and wide. However, moto-inspired bills that are nearly as long as baseball cap visors are becoming the standard these days.

Adjustability is another feature of a visor that must be considered as well. Adjustable visors make it easy for you to push them out of the way if you want a good view of the terrain while you are trail riding. It also makes it easier for you to store up your goggles on your mountain road bike helmet when not in use. Although this feature is more common on most mountain bike helmets, it is less common on Cross Country-focused designs.

You should also bear in mind that mountain bike helmets with adjustable visors do not provide equal amounts of adjustability. Some visors may slide up and down, but do not leave sufficient space for your eyewear protection. However, this may or may not be relevant to you, but it is worth considering when shopping for your next mountain bike helmet.

Camera Mounts

The rise of the action camera market these days has led to the development of mountain bike helmets with camera mounts that offer exciting, first-person perspective. Some mountain bike helmets come with sticky mounts that can be attached to their smooth surface or space at the front.

Some ventilated helmets may not be so easy to mount with cameras; however, with a little tweak here and there, it can be done. Other brands that make heavily ventilated mountain bike helmets also offer strap systems which you can insert in the vent openings or slots to hold everything in place.

Moreover, some sophisticated mountain bike helmets are equipped with built-in action camera mounts. This means you don’t have to worry about guessing the right angle and will also save you a lot of time, especially when it comes to fixing adhesive mounts.
However, you can also use a chest mount or attach an action camera to the handlebars of your mountain bike. But helmets with action camera mounts offer smart solutions and are mostly unobtrusive if you are willing to spend more money.

Compatibility with Eyewear

Standard safety glasses are commonly used by mountain bikers; however, downhill and enduro racers use goggles for increased protection and coverage. Riding with goggles doesn’t require a lot of features. As long as they fit snugly under the bill of your headgear and the shell does an excellent job of keeping the flexible straps in place, you can wear them easily and efficiently.

But then, some features are essential for a mountain bike to have. Accommodating goggles will be easier with these features. For starters, a good mountain bike helmet should come with an adjustable visor. This will make it easier for you to position your goggles at forehead height, especially when not in use. In addition to this, some downhill and enduro helmets come with retainer systems or straps at the rear of the helmet to secure the eyewear. Take note that not all mountain bike helmets come with these features.

When Should You Replace Your Mountain Bike Helmet?

Replacing your MTB road helmet is your personal decision since there are no clear-cut rules out there. Helmets have a shelf life, so if you have been using a mountain bike helmet for more than three to four years, you should start to consider getting a new one. It all depends on how often you use your helmet while riding your mountain bike.

But then, this is not a hard rule. Before you discard the old helmet, take a good look at it. Do you notice any cracks in the foam? Is the inner lining or outer shell of the helmet deteriorating? If you begin to see these signs of degradation on your old mountain bike helmet, it is best to steer on the side of caution and replace it with a new one.

In addition to this, you need to know that as technology advances every day, helmets that were once the rave have gone out of style and have been replaced with newer and more sophisticated models. These changes – especially in safety, technology and fit – could be significant. So, upgrading to a new mountain helmet could be the answer for you if your old helmet is deficient.

You can replace your mountain bike helmet if you get into a crash that compromises the foam inside. This could have a considerable impact on its performance in case you crash again in the future. So, if your helmet has taken a lot of knocking around in the past or is old, you should buy a new one as soon as possible.

It doesn’t matter whether you are an amateur or a pro mountain biker; the helmets highlighted in this style guide will meet your needs.

Here they are in no particular order:

Bell Super 3R Mountain Bike Helmet

If you are looking for a mountain bike helmet that strikes a perfect balance between comfort and protection, the Bell Super 3R fits the bill. This full face helmet comes with a detachable chin strap and gives riders the opportunity to use the full-face coverage option without the bulk and weight that is common with downhill helmets.

For riders who need more room to breathe while riding up the mountainside and extra protection on the way down, the Bell Super 3R helmet is the perfect option for them. According to users who have been involved in violent mountain bike crashes, the Bell Super 3R offered great face protection and reduced the impact of falls significantly.

Adjusting the float fit system of the Bell Super 3R is a piece of cake; you can customize it to fit your head without any fear of pain or discomfort. If you wear the helmet without using the chin bar, the helmet may move about uncomfortably.

This breathable and lightweight helmet is comfortable and is not as conspicuous as its downhill counterparts. The exterior straps, according to some users, may offer some discomfort. But all in all, the Bell Super 3R is a great, multipurpose mountain bike helmet designed to make you as comfortable as you can on as you ride along the trails.

The Bell Super 3R showcases about 23 vents. Six new vents at the brow increase breathability. It also weighs much less – up to 10 grams – than its predecessor. It is also available in a variety of multi- and single-color designs, despite the full coverage. Some are designed for female mountain bikers.

Riders that desire an excellent full-coverage from a mountain bike helmet have applauded the ingenuity that was brought into play when creating the Smith Optics Forefront mountain bike helmet. This helmet is durable, comfortable and integrates excellently with other tools or gadgets you may use or need on your rides.

The Smith Optics Forefront mountain bike helmet can be used with goggles or sunglasses along with any action-mounted camera that you want to use as you ride along the trails. The helmet is also ventilated, though not as much as expected.

The Smith Optics Forefront mountain bike helmet is furnished with Aerocore, an innovative foam technology which incorporates the EPS foam with Koroyd. This new patented material is built to absorb low-speed collision or impact, up to 30% more than regular EPS liners.

The Smith Optics Forefront mountain bike helmet is fitted with MIPS technology to minimize rotational force during a crash or fall, and the VaporFit retention system is user-friendly.

What are the Criteria You Should Use to Choose Mountain Bike Helmets?

Before you purchase a mountain bike helmet, there are factors you must consider. Disregarding these factors could have undesirable consequences on your personal safety and riding experience.

#1: Protection

It should not come as a surprise that this is the number one factor that you should consider when it comes to choosing the best mountain bike helmet for you. You should make the best of any situation, but be prepared for the worst. The best mountain bike helmets out there come with advanced safety features and comfort.

Regular mountain bike helmets come with an in-mold structure comprising a durable outer shell to protect your head as well as a thick layer of EPS foam. The latter absorbs impact which in turn reduces any force on your brain when you get it a wreck.

Technological advancements have improved a lot, and these days, lots of mountain bike helmets come with enhanced protection features such as Multi-directional Impact Protection Systems (MIPS). This additional low-friction layer of protection is included between the hard outer shell and the liner and helps to minimize rotational force.

Mountain bike riders seldom fall on their heads when involved in an accident. In most cases, when they fall off their bikes, the head crashes into the ground at a particular angle which creates an extra rotational force. Rotational forces were not accounted for in most mountain bike helmets until the Multi-directional Impact Protection Systems were developed.

As a result of this, when the rider’s head hits the ground, the MIPS feature makes the helmet to slide in relation to the head. Mountain bike helmets with the MIPS feature cost a bit more, but this is justified if you value the additional protection of your head.

Besides varying technology, mountain bike helmets differ from one model to another. From compact half shell helmet models to full-face styles of physical coverage, there is a broad range of protection a helmet can provide. So, you should consider your riding style and whether or not you need extra face protection. If you do, you may need to choose a mountain bike helmet that comes with a chin guard.

#2: Fit

Your mountain bike helmet must fit your head snugly while providing sufficient protection for your safety. If you choose an ill-fitting helmet, it may not provide the protection that you need when you have a fall. Your mountain bike helmet must not be too tight as this can give you unnecessary headaches. It must also be adjustable to accommodate different head shapes and sizes.

#3: Compatibility

Some mountain bike helmets are designed to be used with cameras or goggles. So, if you love filming while you ride, you need to double-check the helmet you want to buy. If the helmet has no features that support headlamps or cameras, then you may have to go for another option.

#4: Helmet Weight

It’s all about safety, so weight is not all that important. However, your helmet will sit on your head most of the time as you ride along on the trail. So, you need to ensure that the helmet you choose is lightweight.

Thanks to the continuous development of materials and design, mountain bike helmets are lighter, yet offer ample and adequate protection. For long rides, therefore, weight is also a factor that you should consider when choosing any of the best mountain bike helmets out there.

#5: Breathability

You need a breathable helmet with proper ventilation or air flow. You will not only enjoy your ride but also stay safe. Breathable helmets keep you cool while enhancing your focus on the mountain trails as you ride. Moreover, using a helmet that does not offer much air flow will make you have a sweaty head. The helmet may slip around as you ride and may not protect you adequately if you are involved in an accident.

If you frequently ride during in summer or live in a hot area, ventilation and breathability are key factors you should consider when choosing a mountain helmet.

#6: Comfort and Padding

You don’t play with comfort when it comes to selecting the best mountain bike helmet. When a helmet has excellent weight distribution, it enhances comfort. Some helmets come with additional pads to make users feel more comfortable when they wear them. You don’t want to get distracted when riding as a result of wearing an ill-fitting helmet. This could also impair the enjoyment of your ride.

#7: Use

Before you shell out your hard-earned money to buy a helmet, you should consider how you are going to use it. Helmets are available in three categories, and your riding style will depend on the type of headgear you should invest in.

Here are the categories of helmets that are available in the market today:

  • All-mountain riding or Enduro – This type of bike riding is rife with big drops and steep inclines. If you are an All-mountain rider, you need a helmet that covers more of your head with full-face coverage options.
  • Downhill riding (DH) – This is the most technical style of bike riding, with bigger drops and long descents. The chances for big falls are high, and this is why you need a full-coverage helmet that has a downhill rating. It must be part of your gear, and you must never leave home on your bike without it.
  • Cross Country (XC) – Cross Country style of riding is not as intensive as the other two. If this is your style, then you should know that the risk for a high-speed crash is low along with less technical descent. XC helmets have better ventilation features and are lightweight and also provide enough protection for users.

#8: Style

Although it does not contribute significantly to your safety, investing in an attractive mountain bike helmet is vital. If you want to personalize your look, go for a good-looking mountain bike helmet that shows you off as a professional rider.

#9: Value

Mountain bike helmets can cost a lot of money, but then, it is not as expensive as getting a new brain. Okay, that may not be medically possible, but you get the drift. Your head is invaluable and worth every investment you can make to protect it.

If you consider the convenience, safety, and comfort that these mountain bike helmets provide for you, you will appreciate these features and worry less about how much they cost.

#10: In-Mold Construction

Nearly all mountain biking helmets come with in-mold technology. This technology combines a polycarbonate shell with an EPS liner which is then molded together.

The result is a cohesive piece that gives room for cutouts – for ventilation purposes – and reduced weight. Some helmet manufacturers may reinforce the in-mold mountain bike helmet by introducing a framework of Aramid fibers into the central part of the helmet.

The inclusion of this synthetic material enhances protection and durability in an accident. Although other types of construction techniques exist – such as the honeycomb-like Koroyd layer, etc. – none of these other construction systems can beat the in-mold construction technique, both in ventilation and absorption capabilities.

FAQs About Bike Helmets

Should I wear a full face helmet for mountain biking?

Full face helmets are intended for bike riders who are riding difficult terrains and for extra protection when going downhill.

Can you use a road helmet for mountain biking?

Yes, you can use a road helmet for mountain biking, however, since these do not come with visors, it’s best to invest in one that comes with it, so you can be protected against dirt and flies while riding on the mountain.

Why are MTB helmets different?

MTB helmets are created with memory foam, visors, and durable materials that can withstand heavy crashes, which can happen on terrains with roots and pointy rocks. They are different than regular bike helmets as they offer protection to the skull ad neck area.
