A good helmet is a non-negotiable regardless of the route you choose to take, as it can significantly reduce the risk of brain injuries if you happen to experience a crash on your two-wheeled stallion. That is why we impact-tested every helmet and rode thousands of miles around town, trails, and roads.

We prioritized comfort, breathability, and usability in real-world conditions. The result is a list of our favorites for each and every activity, whether you're taking a stroll around the neighborhood or pushing your mileage for a triathlon.

If you want solid protection for everyday riding, there is no better deal than the Smith Signal. It offers a comfortable fit for various biking styles and is under $100.

The Trek Velocis Mips is the lightest helmet we have tested and prevents neck fatigue on longer road routes. For mountain bikers, we recommend the POC Cularis, which is breathable, lightweight, and protective.

Editor's note: We updated this review on April 17, 2026, to include new award-winning products and revamp our recommendations.

Best Bike Helmets


REASONS TO BUY
Comfortable for longer rides
Easy to adjust
Great ventilation
Great impact testing results
REASONS TO AVOID
No visor
Sizing runs large

Who it is best for: The Smith Signal is one of the easiest helmets to throw on and get going. It's comfortable for quick trips or for longer distances, and adjustments are simple. This helmet is well-suited for various styles of bikers, from those who enjoy casual strolls around the neighborhood to commuters and those who are pushing mileage on the road and don't necessarily care about speed.

Why we love it: This helmet was our choice almost every time we took the bike out of the garage. One of our testers exclusively wears this helmet, even tackling long gravel bike races in it. We loved that the helmet stays put, and the adjustment dial stays secure on the lower part of our heads without riding up - all things considered, we didn't have much to dislike about this helmet.

Should you buy it? The Smith Signal offers a lot of value, especially considering where you can take it - road, gravel, trail, or around town. It lacks a visor, which is a minor complaint. Otherwise, if you're new to biking and want a “one-stop shop” helmet, this is a great choice.

Sizes Available: S-XL; 51-65 cm | Rotational Impact Protection: MIPS

The Smith Signal is a do-it-all helmet at a price that is hard to beat. We love the adjustability and found it very comfortable.

Best Road Biking Helmet


Trek Velocis Mips


REASONS TO BUY
Very lightweight
Plenty of vents
Secure fit
REASONS TO AVOID
Pricey
Pads are difficult to remove and clean

Who it is best for: Road bikers who want all-day comfort will appreciate the thoughtful design of the Trek Velocis Mips. Its padding is strategically placed to keep your head happy without adding much bulk or weight. In fact, it is the lightest helmet we have tested. Road cyclists who are pushing the pace, counting every ounce and aerodynamic features, should keep this helmet at the top of their list.

Why we love it: We wore this helmet up and down difficult routes, like Flagstaff Road in Boulder, Colorado, to see how well it could handle strenuous pushes. To our delight, it kept our heads happy and aired out with its large vents. It is very lightweight, easy to adjust, and remarkably secure. Plus, the weight prevented neck strain. It is also among the best impact-tested helmets we have trialed.

Should you buy it? The Velcis is an investment that we feel is worthwhile to road bikers who are pushing the pace but don't want to sacrifice durability or comfort. Even if you are riding around town, this helmet is sure to keep your head comfortable, furthering its appeal as an everyday helmet.

See Deal
REASONS TO BUY
Great impact test results
Comfortable for long rides
Ventilation is superb
REASONS TO AVOID
Pricey

Who it is best for: Mountain bikers who are set on protection and comfort, the POC Cularis is for you. Its ventilation is superb, and the Air Node liner offers a no-itch, dry feel, should you start sweating. This mountain bike helmet is best suited for downhill, trail, and XC riders who don't quite need a full face helmet. This is a helmet you won't want to throw off at every stop due to its comfortable fit.

Why we love it: We appreciate the excellent impact test results this helmet offered. Still, it is remarkably light for a mountain bike helmet. It has the “barely there” feel that other mountain bike helmets lack. Though fairly breathable, we loved that we could pull the liner out and wash it.

Should you buy it? If you're regularly hitting the trails, the Cularis is a worthy investment. It has excellent impact test results for both slow and fast crashes, which is something you'll want on your side when mountain biking. The airy, lightweight feel can be hard to come by without sacrificing impact results, so we think this helmet is worth every penny.

Sizes Available: S-L; 51-62 cm | Rotational Impact Protection: MIPS Air Node

The POC Cularis is an excellent mountain bike helmet, offering plenty of comfort and breathability, as well as topping our impact protection charts.

Most Versatile Bike Helmet


Trek Solstice Mips


REASONS TO BUY
Large breathable vents
Reasonably priced
Fits a wide size range
REASONS TO AVOID
Bulky
Sits tall on the head

Who it is best for: For under $100, the Trek Solstice MIPS offers a surprising amount of comfort and versatility. The back extends low behind the head for a secure fit while still offering enough room for a low ponytail. It's easy to get a good fit thanks to its adjustable dial and ear straps. This do-it-all helmet is a perfect option for those exploring various biking styles but not wanting to go all-in on a road or mountain bike-specific helmet. It's also our top recommendation for those who commute or take family rides around the neighborhood as its comfortable and easy to get the right fit.

Why we love it: This is a full helmet quiver in one product. Its large vents offer plenty of ventilation for warmer days, and the accommodating fit is quick and easy to adjust. It offers enough room to pair a light layer underneath, and the visor kept the sun out of our eyes. Plus, it topped our impact tests.

Should you buy it? The Solstice offers a lot of bang for your buck, especially considering how versatile it is. It's not the most low-profile or aerodynamic, but its comfort will keep you happy for most day-to-day adventures and commutes. We have even taken it on shorter road, gravel, and trail rides and have been happy. If you're after a single do-it-all helmet, this is it.

Sizes Available: S-L; 51-61 cm| Rotational Impact Protection: MIPS

The Trek Solstice is a versatile helmet ready for the day-to-day bike outings. It sits a little tall on the head, but offers unbeatable comfort and airflow.

Best Budget Road Bike Helmet


Lazer Tonic Kineticore


REASONS TO BUY
Easy to adjust
Lightweight
Comes in four sizes
REASONS TO AVOID
So/so ventilation
Limited comfort for long bike rides

Who it is best for: The Lazer Tonic KinetiCore is great for new road bikers who need a good helmet that won't break the bank. This helmet is super light, which means it won't cause neck pain when you're putting in miles looking over your handlebars. While the ventilation isn't the best, its a very easy helmet to adjust and get the right fit, though we have found this to fit narrow heads best.

Why we love it: We love how light this helmet is. We have experienced neck pain from helmets that are heavy, and this one was a relief. It also meant we could strap it to our backpack after a commute without it adding much bulk or weight. It is stylish and offers excellent adjustability. We even keep this helmet on hand for guests who want to go on a stroll while visiting.

Should you buy it? Typically, the lightweight build costs double or triple what the Tonic KinetiCore does. Yet, it doesn't sacrifice protection as shown in our impact tests. If you're willing to trade a bit of breathability for less neck strain, you can't go wrong.

Sizes Available: S-XL; 52-64 cm | Rotational Impact Protection: KinetiCore

Read more: Lazer Tonic KinetiCore review

The Tonic Kineticore is light and highly adjustable. For its price, this is a solid choice for those getting into cycling.

A Budget-Friendly Mountain Bike Helmet


Lazer Lupo KinetiCore


REASONS TO BUY
Large visor
Recessed sides for sunglasses
Adjustable for various head sizes
REASONS TO AVOID
Visor isn't removable
Not the most breathable

Who it is best for: With most mountain bike helmets running over $100, it's a relief to find a helmet that breaks the mold without sacrificing comfort or impact results. The Lazer Lupo KinetiCore is a lightweight helmet built for trail rides for the budget-conscious cyclist. Like its road biking sibling, the lightweight build prevents neck aches on longer rides, and its unique recessed sides prevent glasses from digging into your temples. Plus, its broad sizing makes it suitable for a wide range of riders.

Why we love it: We loved the massive visor that protected our eyes from the sun. On slow-paced neighborhood rides, we even kept our sunglasses packed away as we had enough shade. It is also only available in one size, but our testers with various head sizes were able to get a good fit.

Should you buy it? This stylish helmet is a steal compared to some of the top-end mountain bike helmets. You won't have the most breathability, but the lightweight design is hard to come by. For the new or budget-aware trail biker, this is a solid choice.

Sizes Available: OS; 54-61 cm | Rotational Impact Protection: KinetiCore

We wore this helmet on gravel pursuits and rides around town. We were happy with the comfort and sun protection, though not as airy as we'd like.

Best Impact Testing for Trails


Canyon Deflectr RLS Helmet


REASONS TO BUY
Precise fit
Three-position breakaway visor
Sunglasses holder
REASONS TO AVOID
HighBar system isn't as comfortable as webbing

Who it is best for: The Canyon Deflectr RLS looks different, and it is. It is top-tier when it comes to impact testing with its unique Release Layer System that is designed to “deflect” dangerous twisting energy in a crash. This helmet is also remarkably comfortable, airy, and lightweight. This helmet is great for mountain bikers who have struggled to get the right fit as the HighBar retention strap allows for a more customized fit compared to traditional fabric straps.

Why we love it: Despite being feature-rich, it doesn't weigh a whole lot. It is a helmet we don't mind keeping on between routes as it didn't cause neck strain from being too heavy. It includes a three-position adjustable visor, sunglasses holder, and a magnetic recess for a light. Though not as soft as a traditional strap system, the HighBar dial is super easy to use and it is hard to get the wrong fit, which we loved.

Should you buy it? For all it offers, this helmet is reasonably priced. If fit and impact results are a priority, this helmet should be at the top of your list. While the unique look might appear daunting, it offers “fool-proof” adjustability that tightens to the exact proper spot on your head.

Sizes Available: S-L; 51-63 cm | Rotational Impact Protection: RLS

Read more: Canyon Deflectr RLS review

The Deflectr RLS offers an exceptional fit due to the HighBar adjustment system.

Best Impact Testing for Road


Smith Trace Mips


REASONS TO BUY
Reasonably lightweight
Dual safety system offers top-tier impact test results
Adjustable with gloves on
REASONS TO AVOID
Lacks breathability
Expensive
No sunglasses storage option

Who it is best for: The Smith Trace MIPS is lightweight and reasonably comfortable, and it still managed to crush our impact tests. It has a dual safety system: MIPS (for rotational impact) and Koroyd tech (crumple zones to absorb impact). If a road helmet with excellent impact performance is crucial to you, this road helmet is a great choice, though you'll pay a premium.

Why we love it: The weight is barely noticeable on the head, which is appreciated on longer rides when neck pain tends to creep in. We also loved the low-sitting dial that allowed us to quickly and easily get a good fit with one hand.

Should you buy it? We have some reservations regarding the overall comfort and breathability. The honeycomb impact system can prevent airflow, which caused our heads to run warm during testing. It also isn't ideal for those with large volume heads, as the shallow fit tends to sit high. However, it is still adequate, with the value coming from the top-tier impact testing for both slow and fast crashes. If you're after the best impact results for a road helmet, this is the helmet for you.

Sizes Available: S-L; 51-62 cm | Rotational Impact Protection: MIPS

Most Comfortable for Long Trail Rides


Giro Manifest Spherical


Deal Alert: on sale for 40% off at REI
See Deal
REASONS TO BUY
Precise fit
Lots of vents are breathable
Impressive features
REASONS TO AVOID
High price tag

Who it is best for: When it comes to comfort on the trails, the Giro Manifest Spherical is nearly perfect. The unique fit system provides micro-adjustments around the entire circumference of your head, rather than just pinching the back. The result? An exact fit that is comfortable for hours on end, and it is easy to use. It is also very breathable with plenty of vents leading to deep internal channels to keep your head cool on warmer days.

Why we love it: Everything about this helmet seems well thought out, starting with its safety tech. Instead of a standard plastic MIPS liner that rests against your hair, it uses a “ball-and-socket” dual-shell design. This is exactly what makes the helmet feel so incredibly comfortable air airy - there is no plastic rubbing against your head. The other high-end touches make for an enjoyable experience, from the one-handed magnetic chin buckle to the adjustable visor and the hidden interior rubber grippers to securely hold sunglasses.

Should you buy it? If you're interested in a top-of-the-line daily driver mountain bike helmet, this is it. It comes with a hefty price tag, but the tradeoff is a precise fit and unmatched comfort. This helmet is ready for long days on the trails, and you won't be itching to throw it off.

Sizes Available: S-L; 51-63 cm | Rotational Impact Protection: MIPS/Spherical

The Giro Manifest is well designed, with large vents and a fully adjustable helmet. It is unmatched in comfort.

Most Breathable Bike Helmet


Giro Aries Spherical


Deal Alert: on sale for 29% off at Amazon
See Deal
REASONS TO BUY
21 vents for airflow
Aerodynamic build
Barely-there feel
REASONS TO AVOID
Middle-of-the-road impact test results
Expensive

Who it is best for: If you ride in hot climates or do a lot of high-exertion climbing and need the best ventilation available, the Giro Aries Spherical is for you. It has top-tier cooling and aerodynamics thanks to its whopping 21 vents and ultralight build. The helmet has minimal pressure points, with a “barely there” feel that can be adjusted on the fly with one hand.

Why we love it: The Aries Spherical looks and feels incredibly airy. When headed out on a long road ride, this is the helmet we chose, knowing it would keep us cool. It also feels weightless, minimizing fatigue when looking over handlebars for hours.

Should you buy it? The Aries is one of the most expensive helmets in our lineup. Still, we think it is worth it if you run warm or need the extra airflow. Not many handle ventilation like the Aries. While the impact test results are average, they still meet all federal safety standards. You'll be plenty comfortable in this helmet, and you won't need to worry much about sweat.

Sizes Available: S-L; 51-63 cm | Rotational Impact Protection: MIPS/Spherical

Read more: Giro Aries Spherical review

There are 21 vents total on the Aries Spherical, which is partly why it is so breathable.

What Type of Bike Helmet is Best For You?


Seeing as you will be wearing your bike helmet for hours at a time, it is essential to spend a moment choosing the right features and comfort to fit your needs. Though some helmets work across many general types of riding, there are some specialty helmets you'll want to consider for certain terrain and riding styles, such as a huskier helmet, a more durable helmet for aggressive downhill mountain biking.

If you focus on riding long distances in a more heated climate, having a helmet with great ventilation can maintain a cool head, keeping sweat out of your eyes. In some cases, such as downhill mountain biking, where high-speed crashes are more common, having the right helmet can prevent you from getting a severe head injury. In this review, we will walk you through all the different types of helmets available to help you decide which products have the right features for your needs.

We focus on three main types of helmets in this review:
  • Budget Bike Helmets: Offer a big bang for your buck. These come in various styles and are great for casual, day-to-day rides, though some road and mountain bike exceptions exist.
  • Road Bike Helmets: Best for putting in many miles on pavement. These prioritize breathability, aerodynamics, and comfort.
  • Mountain Bike Helmets: These prioritize protection from impact. They are still comfortable and breathable, but, in general, have less concern with aerodynamics.

Not all helmets are created equal, meaning some are designed specifically for road biking, while others are designed for smashing and bashing down rock, dirt, and rooted trails.   Credit: Matt Lighthart

Budget Bike Helmets


The most widely used and sought-after bike helmets are those that don't have a specialized purpose or hefty price tag. Most of them are suitable for a variety of riding, whether it be dirt trails, a commute to work, or a weekend cruise down the bike path. We were thrilled to see so many budget bike helmets perform so well, as shown in our tests below. Many of these are a “do it all” helmet, meaning you only have to buy one, and it'll be easy on the wallet.

Road Bike Helmets


Road-specific bike helmets are typically the lightest and most well-ventilated helmets. These helmets usually sacrifice a little protection to be as light and aerodynamic as possible. Since road crashes less frequently involve colliding with an object after falling off a bike, they have less protection on the back of the head than other helmet styles. Road bike helmets usually don't have an integrated visor as well. However, it does allow for easy differentiation between road and mountain bike helmets. Since road helmets typically don't have a visor, road cyclists often wear a cycling cap underneath to keep the sun out of their eyes.

Mountain Bike Helmets


Mountain bike helmets typically have more protection than road bike helmets. A mountain bike helmet covers more of the back of the head since you'll likely take a tumble during a mountain bike crash. In general, mountain bike helmets provide more significant protection than road bike helmets; they often weigh quite a bit more. Also, mountain bike helmets have the potential to be less ventilated than road helmets, seeing as they have the extra material for protection.

How to Pick the Best Bike Helmet for You


Once you've figured out the helmet style that best suits your needs, looking at the specific design features of different individual models will help you narrow down the field considerably.

Protection


The entire reason you wear a helmet is to keep your head safe. Every helmet we tested passed federally regulated impact tests. We sent these helmets through another round of testing with a higher threshold to see which ones are more protective than others. Still, it is worth noting that all helmets in this review have met CPSC Bicycle regulations.

A few key aspects make a helmet more protective:
  • A secure and exact fit: getting the right fit with the adjustable dial and chin strap is key.
  • Coverage area: Some helmets cover more of your head than others. Road helmets tend to be shallow and sit higher to save weight and maximize aerodynamics. Meanwhile, mountain bike helmets tend to extend lower over the rear and sides. Typically more coverage is better.
  • Impact absorption: Most helmets use a combination of crushable material (EPS Foam), rotational impact systems (MIPS, Spherical, or RLS), and/or crumple zones (Koroyd, WaveCel, KinetiCore).

Do I need to replace my helmet after a crash?
Most of today's bike helmets are constructed with Expanded Polystyrene (EPS) foam, designed only to withstand one significant impact. The foam liner in these helmets is designed to compress and get crushed while absorbing impact forces. Once a helmet is cracked or impacted, you should replace it as it will no longer provide the same protection. Helmets made using Expanded Polypropylene (EPP), often found in skate helmets, have a more rubbery rebound with multi-impact capability. You can take more hits in these helmets without losing their form and performance, but your skull will absorb more of the impact on each hit.

Protection Technology


When shopping for a helmet, it helps to understand what is actually keeping your head protected.

Shell and Foam: Every modern helmet is built with a hard plastic shell wrapped around a thick layer of crushable foam (often called EPS or EPP). This is your helmet's first line of defense. It compresses and cracks to absorb the force of a direct hit. Some newer helmets use “dual-density” foam, which is a mix of different foams to help protect you in both slow and high-speed tumbles.

Rotational Impact Protection Systems: During a crash, you rarely hit the ground perfectly straight-on. Instead, impacts are usually taken at an angle with a twisting motion. Rotational impact systems fight this. MIPS is the most common system, which utilizes a thin, sliding layer in the helmet that shifts slightly during a crash, absorbing some of the rotational force. While MIPS is a household name, other brands now carry their own proprietary versions of this technology.

Crumple Zones: Crumple zones crush and buckle during a crash to absorb impact, much like a car. Koroyd (used by Smith) looks like a honeycomb and is designed to crush upon impact. KinetiCore (used by Lazer) has blocks and channels molded into the foam that are designed to crumple.

Which technology is best? The jury is still out. We recommend doing some research and deciding for yourself. The cost of these systems has also come down in recent years, adding on average 5-10% to the price of a helmet, so we think they're worth the slight price increase.

Comfort


It doesn't matter if you're going on a quick neighborhood stroll or a long road ride, your helmet needs to be comfortable. Ideally, you shouldn't notice your helmet once it's been strapped on. We call this the “barely there” effect, and you shouldn't want to rip the helmet off at every break.

Even though head sizes and shapes vary from rider to rider, our testers consistently found certain design elements that helped a helmet fit comfortably on different-shaped heads, adding to the overall comfort regardless of the user.

  • Padding design: Good quality padding in the forehead and temple areas is key for comfort. The shape of the liner and the thickness of the padding are also crucial.
  • Full circumference headband adjustability: The most comfortable systems fully wrap around the head to get a more precise fit, rather than just partially.
  • Chinstrap design: We have found that thinner webbing straps and a Y-buckle ear splitter allow the straps to sit flat against the face, as well as prevent rubbing on the ears.
  • Breathability: A sweaty head isn't comfortable. Helmets with a proper ventilation system can keep your head cool and happy. Some helmets have a lot of smaller vents, while others have a smaller number of large vents. Regardless, the goal is to stay aired out and dry.

Adjustability


For a helmet to work properly in case of a spill, it must fit well to protect the specific shape of your noggin. Correct fore/aft positioning, headband tightness, and chinstrap adjustment will help your helmet stay in the proper position atop your head for the highest amount of protection.

Chinstraps: The best helmets have a chinstrap system that attaches under the chin and splits into two straps in front and behind the ear, before attaching to the helmet. Usually, the straps are joined by a plastic Y-buckle just below the ear. The Y-buckle allows you to adjust the straps on many helmets in front and behind. Helmets that utilize an adjustable Y-buckle often earn better scores in our adjustability metric; however, each beautiful cranium is unique, and some helmets without an adjustable Y-buckle still seem to fit a wide variety of head shapes and sizes.

Dials: Dials are among many manufacturers' favored fast skull protector methods. These dials are generally near the back of the helmet to tighten and loosen the helmet's headband. While the tension dials usually work as intended, some are harder to use, particularly on a wintery day with cold hands or while trail riding and wearing gloves. The best dials are easily accessible and easy to operate with gloves. It's also crucial that these adjustment dials do not cause discomfort in the neck when the neck is flexed, which is most of the time when riding extreme terrain.

Weight


The weight of your helmet can make or break the experience. After looking up over your handlebars for an extended time, the weight of a helmet starts to wear on your neck. A long ride with a heavy helmet can leave your neck aching for days. Lighter helmets alleviate this neck pain. Weight, therefore, will affect the comfort of a helmet.

Advancements in helmet technology continue to be made, decreasing the weight without massive impacts on protection. Still, the more coverage a helmet provides, often means the better protection it offers in case of a crash. Road bike helmets tend to be the lightest, but the lack of material can be less protective. Mountain bike helmets provide better head coverage and are typically heavier to fend off rogue tree branches and the occasional dirt spill. Full-face helmets cover most of your head, so they give the most protection and weigh the most; however, they can affect the rider's neck if not used to the weight.

Ventilation


On any hot day, ventilation will come into play when you take your first pedal. With excess heat or long uphill rides, a well-ventilated helmet helps keep your head cooler, keeping your overall body temperature down. Ventilation, therefore, enhances the comfort and performance of a helmet. The best-ventilated helmets are not always those with the most vents, either. Some helmets combine well-placed vents with channels built into the helmet's internal design to create adequate airflow. The Mips system's inner liner is known for sometimes having ventilation blockage, but some of the best helmets have a liner with holes that line up to a helmet's vents.

Durability


Most helmets use a soft EPS foam liner that is susceptible to abrasion. Durable helmets use a design that wraps the shell around the foam's base, leaving very little of the liner exposed to dents and dings. This design keeps helmets relatively protected from minor everyday dings. However, this extra durability measure also adds to the helmet's weight.

No matter how well-constructed, most bike helmets are designed to function for a single impact. So, if you're in a crash and your helmet hits something, you should replace it to ensure your safety. Some helmet manufacturers even have a crash replacement program to encourage you not to keep wearing a helmet that might not protect you as well as the next time you need it.
