Review of Top 9 Best Mountain Bike Helmets under $100 for You
1. Giro Fixture MIPS Adult Mountain Cycling Helmet
The Giro Fixture MIPS has good safety features at a very appealing price range. It is also a stylish lid that is available in a variety of fashionable colors. Purchase it if you want a helmet that prioritizes quality over flashy features.
The reasonably priced Fixture MIPS was made by Giro using a lot of its expertise in helmet design. The Fixture MIPS helmet features a fit mechanism that maintains its adjustment and an internal MIPS liner for added safety.
The non-adjustable visor, limited inside padding, and lack of accessory mounts may stand out to the pickiest cyclists, but for most mountain cyclists, I’d suggest the Fixture MIPS as a great-value alternative.
During the research, I discovered that the venting effectively keeps your head cool, and the Roc Loc fit system makes it incredibly simple to adjust comfort while maintaining a secure fit. Overall, this is a feature-rich helmet at a fantastic price.
Pros
- It is lightweight.
- The price is affordable.
- It comes with a lot of color options.
- The worth of money.
Cons
- It might be difficult for some to adjust its fit.
2. SMITH Engage MIPS Mountain Cycling Helmet
One of the few trail helmets on the market that costs less than £100 and has MIPS and EPS foam to help protect your head from angular hits is the Smith Engage MIPS helmet, and that number appears to be increasing rather quickly.
The Engage’s in-mold design includes the exterior polycarbonate shell wrapping around the EPS foam liner, covering the outer rim of the helmet completely, which is not a characteristic all similarly priced helmets can claim of.
The two-piece cushioning does a great job of absorbing sweat while yet being comfortable. Even though the cushioning isn’t the thickest or plushest available, it still feels very soft and comfortable against the skull.
Even though it costs low, I believe it is an excellent headgear given its performance and features. Its high-quality construction ultimately won me over how it fits and how comfortable it is to wear for extended periods.
Pros
- It is well-ventilated.
- It looks great.
- Feels very comfortable.
- It fits perfectly.
Cons
- It might be difficult for some to adjust its fit.
3. Troy Lee Designs Adult A1 Classic Helmet
One of the best $100 mountain bike helmets available is the Troy Lee Designs A1 Helmet. Tree Lee Designs is one of the best protective gear manufacturers for motocross and mountain riding. Their helmets provide excellent protection and modern design.
To keep your head cool on long, arduous climbs, the helmet incorporates 16 vents. It gives you adequate side and rear head coverage. It is not a modified road helmet; it is made for trail riding.
A1 is ideal for experienced riders on a tight budget who are just getting into mountain biking or eMTB. With optimum coverage and size, this all-mountain, lightweight helmet keeps you safe during all riding activities.
This helmet can fit a range of head sizes thanks to the three positions of the retention strap. The A1 helmet gives the superior fit, coverage, and style you desire, whether tearing through a single track, launching off of dirt jumps, or covering miles on an XC bike.
Pros
- It is certified by DOT FMVSS 218.
- MIPS protection system is present.
- For the price, it’s a very great helmet.
- It provides superior head protection, styling, and coverage.
Cons
- The price is a little bit high.

4. Giro Radix MIPS Men’s Mountain Cycling Helmet
The recently released Radix MIPS from Giro carries on its outstanding legacy of premium mid-range products. It is a durable trail helmet that won’t break the bank and can withstand all-day adventures.
Although it doesn’t feature Giro’s newest and greatest technological advancements, this sturdy helmet offers a very comfortable, secure fit, is lightweight, and has all the essential features you would expect from an updated mountain bike helmet.
The trail-lid style shell doesn’t offer quite as much coverage as the burlier all-mountain shell designs, and the ventilation falls short of the most breathable models now available.
However, the Radix MIPS was one of the coziest helmets you’ll test, and I believe it to be one of the best options available. Any trail rider who values ease of use, weight, style, and features is strongly encouraged to purchase this lid.
Pros
- It feels comfortable.
- It is lightweight.
- The price is affordable.
- Worth the price.
Cons
- It offers average ventilation.
5. Smith Optics Convoy MIPS Mountain Cycling Helmet
This cost-effective Smith Convoy is a comfy, light-weight helmet but lacks the high-end performance and features I discovered in higher-end models. This helmet is a cost-effective choice that will keep you safe on the road.
The Convoy keeps things simple with a set visor position and an easy internal strap mount. It boasts a highly adjustable strap system, MIPS rotational impact protection, and an adaptable, pleasant shape for the EPS shell. However, I discovered that when things get hot, the ventilation is lacking.
This is a decent entry-level model for cyclists new to the sport because it is one of the less expensive mountain bike helmets with rotational impact protection accessible. However, veteran riders will probably want a little more from their helmet.
Pros
- It is a comfortable helmet.
- It is inexpensive.
- It is lightweight.
- It offers a MIPS safety system.
Cons
- Be sure about your sizing.

6. Fox Racing Speedframe Pro Mountain Bike Helmet
The Fox Racing Speedframe Pro was launched into a crowded market of pricey trail helmets, yet it did better than most competitors in its test. You could immediately see that Fox spent much time developing this model once you took it out on the trails.
The MIPS, adjustable visor, eyeglass storage, magnetic Fidlock buckle, enough ventilation, and incredibly adjustable harness system are just a few of the basic features of this top-tier trail helmet. While on the trail, it feels comfortable against your head and offers a cozy, secure fit that gives you confidence.
In its Bicycle Helmet Ratings performance, Virginia Tech has given the Speedframe Pro Helmet it’s highest rating, 5 STARS. The new Speedframe Pro would be a good choice for anyone looking for a new all-purpose trail helmet.
Pros

Cons
- It might feel a bit heavier.

The Bell Spark 2 MIPS Helmet, an all-rounder, satisfies your desire to ride two wheels. It includes MIPS to maintain your confidence and is made to safeguard you while you ride on the trails. The Ergo Fit system is comfortable, while an inside Sweat Guide keeps you dry.
This helmet provides plenty of flexibility for smaller and larger skulls and fits nicely. The helmet has MIPS technology, which provides additional crash protection. This somewhat increases the helmet’s weight, but you won’t notice it once you put it on. This helmet comes highly recommended.

Because of its confidence-inspiring expanded coverage, unmatched comfort, and thoughtful design, Troy Lee Designs’ A1 Classic MIPS helmet has become a favorite helmet.
Its modern MIPS version provides better defense against brain injury brought on by rotational forces, which is unquestionably a good thing.
Due to its overall fit and extensive inside padding, the A1 MIPS is one of the safest helmets on the marketplace. It had an exact shape and, as far as I noticed, no odd bumps or irregularities in the molding’s contours.
It fits snuggly in all the correct areas, and the soft, thick padding is deformed enough to smooth out any unusual lumps or bumps on your head. In short, bikers felt that the A1 is far more comfortable and is lighter, more ventilated, and more durable for everyday use.

This helmet will keep you safe when the trails get challenging. Its in-mold polycarbonate outer shell is thin and light, protecting you without adding weight.

What to Look for While Choosing the Best Mountain Bike Helmet for $100?
There are several mountain bike helmets available for less than $100. Cost, fit, MIPS, and ventilation are some significant factors. Finding an MTB helmet that fits, feels cozy, and is appropriate for the type of riding you undertake is crucial.
Be careful to think about the following factors when you buy a new mountain bike helmet:
Fit and Comfort
Different helmet manufacturers make various helmet shapes. It’s crucial to have a good, snug, comfortable fit. If you fall, a helmet that feels floppy might not stay in position. Your helmet won’t protect your head if it comes off. Don’t hesitate to try on various helmets until you discover one that feels comfortable.
Straps
The straps on some helmets can be adjusted more easily than others. The angle at which the helmet rests on your head can be adjusted more easily thanks to adjustable ear straps.
You can adjust the angle to make it more up- or down-angled. A helmet with more adjustment options will fit you better and be able to stay in place if you fall.
Ventilation
Your head will stay cooler with larger and more vents. Larger vents can be used in helmets made of more durable and energy-absorbing materials. Many vents are good if you want to ride in the summer heat. If you intend to ride in the winter, you might prefer something with fewer vents.
Style
There is a wide variety of helmets, each with its unique design. The back of the head is typically protected in mountain biking helmets. The designs of road helmets are typically simple.
A helmet is useless if you do not wear it when you fall. Choose a helmet that matches your head shape so you’ll actually wear it. A full-face helmet is recommended for cycling downhill or on trails with many huge drops.

MIPS
On collision, the MIPS brain protection system lets your head to spin inside the bike helmet. If you land a glancing blow on something, such as a tree, your helmet will rotate around your head. The rotational strain on your head and brain is reduced for this reason.
If MIPS are not used, your head will be torqued as it rotates with the helmet. It gives another layer of defense against various impact directions. As a mountain biker, I wouldn’t put on a mountain bike helmet that did not have MIPS.
Padding
Padding on helmets might vary. Road bike helmets may have limited cushioning. The most crucial consideration is weight. A comfier recreational helmet can offer more padding.
Look for cushioning that has been designated for quick drying. You won’t want your helmet to make you feel like a wet sponge after your ride.
Weight
Some bike helmets are significantly heavier than others. A full-face mountain bike helmet designed for downhill riding will be significantly heavier than a road racing helmet. MIPS, for example, add weight to a helmet.

Frequently Asked Questions (FAQS)
What safety characteristics should I search for in a mountain bike helmet?
When it comes to the level of protection provided by a helmet, adequate head coverage is critical. Most mountain bikers ride tricky portions of the route, and it is ideal to have an extended helmet structure cushioning your fall if you crash.
A better-fitting helmet that improves protection to the base of your skull is a great option, and many of the top low-cost helmets these days offer this extra level of protection.
Many well-protected MIPS mountain bike helmets are available for under $100. MIPS, formerly reserved for expensive products, is now available on more budget helmets and is an excellent choice for keeping your head safe.
Is a low-cost mountain bike helmet as good as a high-priced one?
Mountain bike helmets that are less expensive can be as safe as more expensive ones. All helmets sold in the United States must comply with the CPSC standard.
Virginia Tech’s helmet safety ratings provide unbiased results of their research.
I recommend purchasing a helmet with MIPS, WaveCel, or comparable safety technologies for better safety.
Why are quality helmets so pricey?
Manufacturers invest considerably in testing, weight reduction, ventilation, aerodynamics, etc. They also sponsor many athletes and teams. Therefore, all of these activities raise the final cost.
Is MIPS preferable over WaveCel?
No impartial or unbiased testing has determined which safety method is superior. However, the distinction between the two is that WaveCel lowers rotational and linear forces. But only the rotational ones are MIPS.
Do mountain bike helmets need to have several vents?
Your risk of experiencing discomfort while riding on a warm day increases with the coverage a helmet offers. Regarding thermal comfort and reducing perspiration, airflow is crucial.
Making a helmet with enough ventilation is difficult. Designers are reducing material for every vent port they create. Through advanced computer modeling and software, they can predict where material can be reduced to improve airflow without putting the wearer at an elevated risk of accident injuries.
Although there isn’t a set number for vents, helmets with more than 20 ports and internal channeling across the head typically allow for better airflow. When you are climbing slowly on a hot day, this is a most obvious factor.
My Final Thoughts
Since mountain biking can be a high-impact sport, wearing a helmet while racing over difficult terrain is crucial.
It can be difficult to pick an ideal helmet that can shield you from the inevitable collision and is also strong enough to last, lightweight so you don’t feel it, and well-ventilated so you can ride for hours.
Keeping yourself secure doesn’t have to break the bank always. These best mountain bike helmets under $100 offer protection and style at a fantastic value. I genuinely hope that our thorough research was able to guide you on the right path.
