Best Mountain Bike Helmet Under $100



Introduction

If you do a lot of mountain biking, you know that it is only a matter of time before you will crash and hit your head. So, it’s important to have a good quality bike helmet that will not only protect your head in a crash, but is also lightweight and comfortable to wear. You want to look for a bike helmet that is easy to adjust, well ventilated, and durable. Here are a few tips and reviews to help you find the best mountain bike helmet under 100.


Considerations When Choosing in the Best Mountain Bike Helmet Under 100



Finding the Best Fit


When you choose a mountain bike helmet, you want to make sure you have a secure fit. It should be snug, but not super tight, and it should sit just an inch over your eyebrow. If you wear glasses or use sunglasses, you also want to make sure there is enough room on the side of the helmet for the glasses to fit correctly and comfortably.

Most importantly, you don’t want any area of the helmet to be super tight. Any area of the helmet that is not making secure contact with your head should have added liners or pads for extra comfort.

When sizing your helmet, you will notice that they come in fairly general sizes including large, medium, and small choices. Measure around your head just over your eyebrows to determine which of these sizes is the best choice for you, and then look for the size range where your measurement falls.


Type of Helmets


There are a few types of helmets to choose from when you go mountain biking. While some experts claim that you need a full-face mask, others find that they aren’t necessary if you aren’t going on rough terrains with steep declines or ramps.

In any risky situation, you need to protect your head. However, if you are just riding along dirt paths or through hills, then a typical mountain bike helmet should be fine. Look for helmets with a visor that will help keep the sun out of your eyes. You also want something adjustable since there isn’t really a one size fits all option when it comes to a mountain bike helmet.


Where and When Do You Go Mountain Biking?


Where and when you plan to use your mountain bike will tell you if you need a visor. If it's not a sunny area, then you can get away without one, although having one that you can easily attach is good just in case.

If you plan to ride at night, you will need a helmet that has an integrated taillight. It’s always important to be illuminated when you ride in the dark, which can protect you, car, and animals that might be roaming in the hills.


Features to Look for in the Best Mountain Bike Helmet


Comfort


Above all else you want your mountain bike helmet to be comfortable. This is important because if it isn’t, you may not want to wear it. Skipping your helmet should not be an option. You want it to be snug, but not uncomfortably tight, and it should move just a little when you attempt to rotate it. 



Safety


It is standard for any mountain bike helmet to meet the U.S. Consumer Product Safety Commission standards as well as the American Society of Testing and Materials requirements. These standards are required for any helmet regardless of its cost, features, or design.


Knowing this allows you to purchase your helmet based on your own needs instead of trying to tell whether each helmet is safe to wear. And, when considering your needs, think about where you plan to wear it so you know if you need a full-face helmet for dangerous riding or an open face helmet for a ride along a simple trail.


Straps


For safety reasons, you will want the helmet straps to fit nice and snug under your chin and also around your ears. It’s worth spending just a little more money on a helmet that gives you straps that are made with good quality and more comfortable material.


Inside Padding


You will find that some helmets have a more comfortable inside padding than others do. This cushier padding is often found in a higher quality helmet that will also offer moisture-wicking that you will appreciate on long, hot days.


Ventilation


You will need to spend a little more money on your helmet to get decent ventilation. This is an important feature if your mountain biking on hot days and you want your head to stay cool when you are working hard. If you plan to bike in the wintertime, you can easily add a warm hat or cap under the helmet to keep you warm.


Retention System


You will find that most helmets on the market come with a retention system in the back. This allows you to have a comfortable but snug fit.

With a retention system, you will usually find a dial in the center that you can tighten to fit the helmet to your head. This can really be useful if you ride both with and without a cap so your head size can change depending on the situation.


Weight


The more you invest in a mountain bike helmet, the more lightweight it will be. This can be important if you will be wearing it for hours at a time.

The helmet will also be more durable and aerodynamic, which can be important if you are racing. Typically, bike helmets are made with expanded polystyrene and are covered with an outer shell. Better quality helmets will have the two layers fused together.

Cheap helmets will have tape or glue holding the outer plastic shell to the inside foam liner. Keep in mind that these helmets tend to fall apart after a short amount of time, especially if it is used in hot weather.
