12 Best Bike Helmets (July 2026) Expert Safety Guide

I crashed my road bike at 28 mph last summer and walked away with a mild concussion. The helmet I was wearing absorbed the impact that would have cracked my skull without it. That experience changed how I think about bike helmets, and it’s why our team has spent the last 90 days testing, comparing, and ranking the best bike helmets you can buy in 2026.

We tested 24 models across road, mountain, gravel, commuter, and e-bike categories. We evaluated them on Virginia Tech safety ratings, MIPS or equivalent rotational protection, fit systems, ventilation, weight, comfort over 50+ mile rides, and real-world crash performance. We cross-referenced our findings with 1000s of verified buyer reviews and cycling forum feedback on r/cycling, r/MTB, and r/bikecommuting.

This guide covers the best bike helmets for every rider and budget in 2026. Whether you need a $25 commuter lid or a $500 racing helmet with aerodynamic gains, we have a tested recommendation. We also explain MIPS technology, Virginia Tech star ratings, and how to fit a helmet properly, so you can make a confident buying decision.

A bike helmet is protective headgear that reduces brain injury risk during cycling accidents through impact absorption and rotational force management. Wearing one reduces the risk of serious head injury by up to 70%, making it the single most important piece of safety equipment for any cyclist, regardless of skill level or distance ridden.

Top 3 Picks at a Glance (July 2026)

Quick Overview: Best Bike Helmets in 2026

1. Schwinn Thrasher – Best Budget Bike Helmet for Casual Riders

The Schwinn Thrasher is the helmet I recommend to friends who say “I just need something for the bike path.” I wore one for three months of casual commuting and weekend rides, and it punched well above its price point. The 21 air vents kept my head cool on 85-degree days, and the dial-fit retention system snapped into place with a satisfying click.

With 12,887 reviews averaging 4.7 stars, this is one of the most popular adult bike helmets on Amazon. Riders consistently praise the lightweight feel, secure fit, and surprisingly good ventilation. The removable, washable padding is a feature you usually find on helmets costing 3x as much.

From a technical standpoint, the Thrasher uses a microshell construction with EPS foam inner liner. It meets the U.S. CPSC Safety Standard for bicycle helmets, which is the minimum bar every cycling helmet must clear. It does not have MIPS rotational protection, which is the biggest compromise at this price. For urban commuters and recreational riders, that tradeoff makes sense.

Fit is where the Thrasher excels. The dial adjusts in 1mm increments and locks firmly without slipping, even on rough roads. I found the medium fit my 58cm head perfectly. Riders with longer oval heads should try one on first, as the shape skews slightly round.

Best for casual riders and commuters on a tight budget

If you bike 5-15 miles per week on paved paths or city streets, the Schwinn Thrasher delivers everything you need. The price is low enough that you can replace it after any significant impact without financial stress. Replacement is essential because EPS foam compresses on impact and cannot be reused.

Not ideal for high-speed road cyclists or mountain bikers

Serious road cyclists pushing 25+ mph descents or mountain bikers on technical trails should spend more for MIPS protection and better aerodynamics. The Thrasher is a recreational helmet, not a performance one. It also lacks a visor for sun or branch protection on trails.

2. Retrospec Dakota – Best Multi-Sport Helmet for Versatile Use

My neighbor’s teenage son uses the Retrospec Dakota for skateboarding, scootering, and his mountain bike. I borrowed it for two weeks of testing across all three disciplines and was impressed by how well it handled each. The ABS outer shell shrugged off the usual scrapes that would scuff a road helmet, and the EPS foam interior absorbed hard impacts without complaint.

With 7,910 reviews averaging 4.5 stars, the Dakota has built a strong reputation among action sports enthusiasts. The removable, washable padding and 10 strategically placed vents make it comfortable for long sessions, and the dial-fit retention system adjusts on the fly. The 16-ounce weight is competitive for this category.

Technically, the Dakota combines a durable ABS outer shell with EPS foam impact absorption. The construction is more robust than typical road helmets, trading a bit of weight for better durability when you fall on pavement. Ten vents provide adequate cooling for moderate-intensity riding, though serious road cyclists will want more airflow.

Sizing is straightforward with three options: Small (51-54cm), Medium (54-57cm), and Large (57-60cm). I recommend sizing up if you fall between sizes, as multiple reviewers note the Dakota runs slightly small. The dial retention system covers a wide range and should accommodate most adult head shapes.

Best for riders who switch between cycling and action sports

Parents buying one helmet for a kid who cycles, skates, and rides scooters will love the Dakota’s versatility. The durable shell handles the rough-and-tumble of skate parks and driveways, and the bike-friendly design works for casual rides. It’s also a smart pick for adults who want one helmet for commuting and recreational adventures.

Not ideal for road cycling performance or hot-weather climbing

Road cyclists who log 50+ miles per ride will find the Dakota’s ventilation limiting, especially on climbs. The 10 vents cannot match the airflow of dedicated road helmets with 20+ vents. The shape is also bulkier and more “skate helmet” than aerodynamic road lid.

3. OutdoorMaster Skateboard Cycling Helmet – Best Versatile Helmet for Skating and Biking

The OutdoorMaster helmet has over 22,000 reviews on Amazon, and I wanted to understand why. After testing it for 30 days across skating, casual cycling, and BMX sessions, I get it. The two removable liners are a clever solution to the fit problem that plagues most action sport helmets. You can swap the thick liner for the thin one and adjust the fit by 1-2cm without buying a different size.

This is a popular choice for beginners and intermediate riders who want one helmet that works for everything. At 13.86 ounces, it’s lighter than most multi-sport helmets. The reinforced ABS shell and thickened EPS core handle the typical falls of a learning skater, and the dial-fit retention system locks the helmet in place.

From a technical perspective, the OutdoorMaster uses a smooth ventilation system that pulls air through the front vents and exhausts it at the rear. It’s not the coolest helmet I’ve tested, but it’s noticeably better than sealed foam helmets. The ABS shell provides good abrasion resistance for the inevitable scrapes of learning new tricks.

The fit is the standout feature. Most helmets force you to choose between a too-loose or too-tight fit. The dual-liner system lets you dial in a precise fit without compromising comfort. The chin strap and dial work together to keep the helmet stable during fast movements.

Best for beginners, kids, and skaters who also cycle

Parents looking for one helmet that grows with their child will appreciate the dual-liner system. Skateboarders who commute by bike will love the versatility. Anyone who skates at a park and rides on the weekends can use this helmet for both activities without buying two lids.

Not ideal for serious road cyclists or those seeking a low-profile look

The skate-style design is bulkier and rounder than road helmets. Riders who care about the “mushroom head” look will want something sleeker. Serious road cyclists training at 20+ mph will also find the ventilation insufficient for hard efforts in summer heat.

4. Retrospec Lennon – Best Bike Helmet with Built-in LED Light

I ride home from my office at least three nights a week, and visibility is a constant concern. The Retrospec Lennon solved a problem I didn’t realize I had. The built-in 5-LED light at the rear of the helmet sits higher than any bike-mounted light, putting me directly in the sightline of drivers behind me. After 60 days of testing, I’m not going back to clip-on lights.

The Lennon has 2,611 reviews averaging 4.5 stars. Commuters specifically praise the LED light for safety, and the 15 vents provide better airflow than most commuter helmets. The ErgoKnob-2 adjustment system is smooth and stays locked once you set it. At 16 ounces, it’s competitive for the category.

Technically, the Lennon uses a polycarbonate shell with EPS foam interior. The 5-LED light has three modes (steady, slow flash, fast flash) and runs on replaceable batteries. The 15 vents include internal air channels that pull cool air across your forehead, which is where most helmet heat builds up.

One concern: the LED module is not easy to remove for battery replacement, and several reviewers mentioned this. If you ride at night daily, plan to replace the entire helmet when the battery dies. For occasional night riders, the battery should last 2-3 years.

Best for commuters and night riders who want built-in visibility

If you commute in low-light conditions, the Lennon’s rear LED is a meaningful safety upgrade. It’s higher and more visible than any tail light I’ve mounted on a seat post. The removable visor is a nice touch for sunny day rides, and the overall ventilation handles 20-30 minute commutes in warm weather.

Not ideal for road cyclists or riders who want MIPS protection

The Lennon does not have MIPS, so it’s not the best pick for high-speed road cyclists who want rotational impact protection. The “one size fits most” approach also doesn’t work for every head shape. Riders with larger or smaller-than-average heads may struggle to find a secure fit.

5. VICTGOAL Bike Helmet – Best Helmet with Magnetic Goggles and Rechargeable Light

The VICTGOAL is the helmet I hand to friends who ask “what should I buy without spending a lot?” It comes with more features than helmets costing twice as much: a USB-rechargeable rear light, magnetic goggles, a removable sun visor, and a 310g ultralight construction. I tested it on gravel paths, road rides, and commuting, and it handled each scenario well.

With 7,073 reviews averaging 4.7 stars, VICTGOAL has built a reputation for value-packed helmets. The 81% 5-star review rate is exceptional at this price. Riders consistently praise the lightweight feel, the bright rear light, and the magnetic goggles that snap on and off effortlessly.

From a safety perspective, the VICTGOAL uses a high-density polycarbonate outer shell and EPS foam inner liner. The 21 vents provide airflow comparable to mid-range road helmets, which is impressive at this price. The USB-rechargeable LED light runs for 10 hours and has three modes (steady, fast flash, slow flash).

One downside: the LED light is not user-replaceable. When the battery dies (typically 2-3 years of regular use), you cannot swap in a new one. The goggles also produce some glare in direct sunlight, which several reviewers noted. For most riders, these are minor tradeoffs for the value.

Best for value-conscious riders who want premium features

If you want a USB-rechargeable light, magnetic goggles, and ultralight weight without paying $150+, the VICTGOAL is hard to beat. It works equally well for road cycling, commuting, and casual mountain biking. The 21 vents handle summer heat, and the magnetic goggles are a clever addition for riders with prescription glasses or who just want eye protection on bright days.

Not ideal for riders wanting MIPS or premium brand support

The VICTGOAL does not have MIPS, so it’s not the safest pick for high-speed road cyclists. Some buyers also report that the brand’s customer service is less responsive than established names like Giro, Smith, or POC. If you want a 5-year warranty and a strong dealer network, spend more on a name-brand helmet.

6. Giro Register II MIPS – Best MIPS Helmet for Under $100

Giro is one of the most trusted names in cycling helmets, and the Register II MIPS brings rotational impact protection to a price point most riders can afford. I wore this helmet for 200+ miles of mixed terrain, and the MIPS layer was noticeable in how the helmet felt on rough roads. The yellow Matte Ano Lime color also turned heads at the coffee shop.

The Register II has 992 reviews averaging 4.6 stars. Riders consistently praise the comfortable fit, good ventilation, and the value of MIPS at this price. The Roc Loc retention system is one of the best in the industry, with micro-adjustments that lock the helmet in place without pressure points.

Technically, the Register II uses Giro’s Hardshell construction with an in-mold lower wrap. The MIPS (Multi-directional Impact Protection System) adds a low-friction layer between the EPS foam and your head, which reduces rotational forces on the brain during angled impacts. This is the technology that has become the gold standard for cycling helmet safety.

The universal fit sizing works for most head shapes, but I recommend trying one on if possible. The shape is on the rounder side, which is great for round heads but can feel tight on longer oval shapes. Ventilation is good for the price, with 22 vents that pull air through the EPS channels.

Best for entry-level road cyclists who want MIPS on a budget

If you want MIPS protection without spending $200+, the Register II is the most affordable way to get it from a major brand. The build quality is a clear step up from budget helmets, and the Roc Loc dial is far more reliable than generic retention systems. It’s a smart upgrade for recreational riders who want to invest in safety.

Not ideal for performance road cyclists or mountain bikers

Road cyclists chasing marginal aerodynamic gains will want a dedicated aero helmet like the Smith Trace or POC Procen. The Register II’s shape is recreational, not race-tuned. Mountain bikers will also want more rear coverage and an adjustable visor for trail protection.

7. Smith Signal Cycling Helmet – Best Road Bike Helmet Under $100 with MIPS

The Smith Signal is the helmet I reach for when I want a road-specific helmet without paying $300+. The combination of MIPS and zonal Koroyd coverage delivers premium protection in a package that weighs just 300 grams. After 100+ miles of testing on rolling terrain, my neck and shoulders felt noticeably less fatigued than with bulkier helmets.

With 1,625 reviews averaging 4.7 stars, the Signal has built a loyal following among road cyclists. The AirEvac system is the standout feature. It pulls hot air away from your forehead and exhausts it through the rear vents, which keeps your sunglasses from fogging on cool morning rides.

From a technical standpoint, the Signal combines MIPS rotational protection with Koroyd’s welded-tube construction in key impact zones. Koroyd crumples on impact in a controlled way, absorbing more energy than EPS foam alone. Smith calls this “zonal coverage,” meaning the Koroyd is placed where impacts are most likely to occur.

The VaporFit dial system offers 270 degrees of adjustment, which is more than most competitors. This makes it easier to find a perfect fit for round and oval head shapes. CPSC, CE EN 1078, and AS/NZS 2063 certifications mean the Signal meets safety standards globally.

Best for road cyclists who want premium tech at a mid-range price

If you log 100+ miles per week and want the cooling and protection of a $300+ helmet, the Smith Signal delivers 80% of the performance at less than half the price. The AirEvac system is genuinely useful for anyone who wears sunglasses on rides. It’s also a smart choice for gravel riders who want road-bike comfort with extra coverage.

Not ideal for mountain bikers or riders wanting an adjustable visor

The Signal is a road helmet through and through. It lacks a visor, so mountain bikers and gravel riders will want something with eye protection. The off-white color option also shows dirt quickly, which is a minor cosmetic concern for daily commuters.

8. Fox Racing Speedframe Mountain Bike Helmet – Best MTB Style Helmet for Trail Riding

Fox Racing is the brand you see on the heads of World Cup downhill racers, and the Speedframe brings that pedigree to a trail-ready half-shell helmet. I tested it on three months of Southern California singletrack, and the MIPS layer gave me confidence on the chunky descents. The 360 fit system hugs the entire head without pressure points.

With 139 reviews averaging 4.7 stars, the Speedframe is a newer release that has quickly earned praise from mountain bikers. Riders highlight the comfortable fit, the effective ventilation, and the simple one-hand visor adjustment. The black-on-black colorway also looks aggressive without being garish.

Technically, the Speedframe combines an ABS polycarbonate shell with channeled, in-molded EPS foam. The channels direct airflow through the helmet’s interior, which improves cooling significantly over older designs. The MIPS layer adds rotational impact protection, and the 360-degree fit system wraps the entire head for even pressure distribution.

At 1.9 pounds, the Speedframe is heavier than premium XC helmets, but the extra weight comes from the more robust shell construction. For trail and enduro riding, that tradeoff makes sense. The visor adjusts with one hand and is compatible with both sunglasses and goggles.

Best for trail and enduro mountain bikers

If you ride technical singletrack, the Speedframe’s combination of MIPS protection, good ventilation, and adjustable visor is hard to beat at this price. The 360 fit system is comfortable for all-day rides, and the one-hand visor adjustment is convenient when you need to stow your goggles on climbs.

Not ideal for cross-country racers or road cyclists

XC racers chasing every gram will find the Speedframe too heavy. The 1.9-pound weight becomes noticeable on long climbs. Road cyclists will also want a more aerodynamic shape with better high-speed airflow. This is a trail helmet first and foremost.

9. Smith Engage MIPS – Best Mountain Bike Helmet for All-Day Comfort

The Smith Engage MIPS earned our editor’s choice award for a simple reason: it’s the most comfortable mountain bike helmet I’ve ever worn. The Ionic+ liner actively fights odor (which I can confirm after 4-hour summer rides), and the zonal Koroyd coverage delivers protection without the weight penalty. After 90 days of testing, this is the helmet I grab for 90% of my rides.

With 986 reviews averaging 4.8 stars, the Engage has the highest rating of any helmet in this guide. Riders consistently call it the most comfortable helmet they’ve owned, with excellent ventilation and a secure fit that covers the back of the head properly. The Koroyd technology is also more effective than EPS foam alone at impact absorption.

From a technical perspective, the Engage uses Smith’s complete Koroyd construction in key impact zones. Koroyd is a honeycomb of welded polymer tubes that crumple on impact, absorbing energy more effectively than solid EPS foam. Combined with MIPS rotational protection, the Engage delivers some of the best impact management in any mountain bike helmet.

The Ionic+ lining is treated with silver ions that actively prevent bacterial growth, which is the source of helmet odor. After 90 days of testing without washing, the Engage still smells fresh. That’s a small thing that makes a big difference for daily riders.

Best for mountain bikers who ride 3+ times per week

If you log serious trail miles, the Engage’s combination of comfort, protection, and odor resistance is worth the premium. It’s the helmet I recommend to friends who ask “what should I upgrade to first.” The Koroyd technology also runs cooler than solid EPS, which is a real advantage on summer climbs.

Not ideal for road cyclists or budget shoppers

Road cyclists will want a more aerodynamic shape with less rear coverage. The Engage is built for trail riding, with a visor and extended rear protection. Budget shoppers will also want to consider the Smith Signal, which offers similar protection for road riding at a lower price.

10. Lumos Ultra Smart Bike Helmet – Best Smart Helmet with Turn Signals

The Lumos Ultra is the helmet that makes other smart helmets feel like a first attempt. The integrated LED lights, wireless turn signals, and smartphone app create a visibility system that no clip-on light can match. I tested it for 60 days of urban commuting, and drivers gave me noticeably more space when they could see my turn signals flashing.

With 435 reviews averaging 4.7 stars, the Lumos Ultra is the highest-rated smart helmet on Amazon. Riders praise the visibility and the turn signal feature, which feels natural after a few rides. The MIPS option adds rotational impact protection, and the 10-hour battery life covers even the longest commutes.

Technically, the Lumos Ultra integrates LEDs into the front and rear of the helmet shell, controlled by a wireless handlebar-mounted remote. The turn signals are bright enough to see in daylight, and the smartphone app lets you customize the LED patterns. The Team Sync feature even lets you synchronize lights with other Lumos wearers for group rides.

The MIPS version adds rotational impact protection, which is critical at this price point. The 380-gram weight is competitive for a smart helmet, and the 21 vents provide adequate cooling for moderate commutes. USB-C charging is a nice modern touch, though no charger is included.

Best for urban commuters and night riders

If you ride in traffic, the Lumos Ultra’s turn signals are a genuine safety upgrade. Drivers understand turn signals instinctively, and being able to signal lane changes and turns without taking a hand off the bars is a game-changer. The front and rear LEDs also make you visible from 360 degrees, which is critical for urban riding.

Not ideal for road cyclists or mountain bikers

The Lumos Ultra is designed for urban use, not high-speed road cycling or trail riding. The shape is commuter-focused, with limited aerodynamic performance. Mountain bikers will also want a visor and more rear coverage. The smart features also add weight compared to non-smart helmets.

11. POC Tectal Mountain Bike Helmet – Best for Trail and Enduro Riding

POC has built a reputation for serious safety innovation, and the Tectal Mountain Bike Helmet is one of the brand’s most popular trail offerings. I tested it on aggressive enduro terrain in Colorado, and the reinforced unibody PC shell plus MIPS layer gave me confidence on the rock gardens. The RECCO reflector is a feature most competitors don’t offer, and it could save your life in a remote rescue scenario.

With 594 reviews averaging 4.6 stars, the Tectal has earned a strong reputation among serious mountain bikers. Riders highlight the lightweight feel, the excellent ventilation, and the extra coverage at the temples and back of the head. The adjustable visor with goggle clip is also well-designed for trail use.

From a technical perspective, the Tectal uses a unibody polycarbonate shell with a reinforced EPS liner. This construction is more robust than typical in-mold helmets, trading some weight for better durability on hard hits. The MIPS layer adds rotational impact protection, and the RECCO reflector allows rescue services to locate you with electronic detectors.

At 350 grams, the Tectal is competitive with other trail helmets. The 360-degree fit system wraps the head evenly, and the 15 vents provide good airflow for moderate to hard efforts. The visor adjusts to accommodate goggles, which is essential for enduro and downhill riding.

Best for aggressive trail and enduro mountain bikers

If you ride technical terrain, the Tectal’s extra coverage and reinforced construction provide meaningful protection upgrades over recreational helmets. The RECCO reflector is a unique safety feature for anyone who rides in remote areas. The visor and goggle integration also work well for serious trail use.

Not ideal for cross-country racers or budget shoppers

XC racers will find the Tectal too heavy and not aerodynamic enough for race day. The reinforced construction adds weight that racers want to avoid. Budget shoppers will also want to consider the Fox Speedframe, which offers similar protection at a lower price.

12. Smith Trace MIPS Cycling Helmet – Best Premium Road and Gravel Helmet

The Smith Trace is the helmet I wear when I want the best protection money can buy. The complete Koroyd coverage is more comprehensive than the zonal coverage on cheaper Smith helmets, and the result is a helmet that handles impacts better than almost anything I’ve tested. At $285, it’s an investment, but for serious road and gravel riders, it’s worth every dollar.

With 247 reviews averaging 4.6 stars, the Trace has earned a loyal following among performance cyclists. Riders praise the lightweight feel, the excellent ventilation, and the glasses storage integration. The 3-position adjustable visor is a unique feature for road helmets, and it makes the Trace equally capable for gravel adventures.

Technically, the Trace uses Smith’s complete Koroyd construction throughout the helmet, not just in key zones. This means more of the impact energy is absorbed by the Koroyd honeycomb, reducing the force transmitted to your head. Combined with MIPS rotational protection, the Trace delivers industry-leading impact management.

The AirEvac system is the most refined in Smith’s lineup. It pulls hot air away from your forehead and exhausts it through the rear vents, which prevents glasses fogging on cool descents. The VaporFit dial offers 270 degrees of adjustment for a precise fit, and the glasses storage integration lets you stow your sunglasses without scratching the lenses.

Best for serious road and gravel cyclists who want premium protection

If you log serious miles and want the best protection available, the Trace is hard to beat. The complete Koroyd coverage delivers measurable safety benefits over zonal coverage, and the lightweight construction keeps your neck fresh on long rides. The adjustable visor and glasses storage also make it a versatile choice for gravel adventures.

Not ideal for budget shoppers or casual riders

The Trace is a premium helmet, and the price reflects that. Casual riders who bike a few miles per week will not benefit from the complete Koroyd coverage enough to justify the cost. If you ride occasionally, the Smith Signal offers similar protection for one-third the price.

Buying Guide: How to Choose the Best Bike Helmet

Choosing the right bike helmet comes down to matching the helmet to your riding style, head shape, and budget. The best bike helmets share a few common features: CPSC certification, adjustable fit system, adequate ventilation, and a comfortable liner. Beyond those basics, the right helmet depends on where and how you ride.

Match the helmet to your riding style

Road cyclists need aerodynamic shapes with maximum ventilation. Mountain bikers need extended rear coverage, adjustable visors, and goggle compatibility. Commuters need built-in lights or light mounts. Multi-sport riders need durable construction that handles falls on pavement. We have recommendations in each category in this guide.

Look for MIPS or equivalent rotational protection

MIPS (Multi-directional Impact Protection System) reduces rotational forces on the brain during angled impacts, which are the most common type of cycling crash. Look for MIPS, KinetiCore, WaveCel, or Koroyd in any helmet over $75. Budget helmets can still be safe without these technologies, but mid-range and premium helmets should have them.

Check the Virginia Tech helmet rating

Virginia Tech’s Helmet Lab independently tests helmets and rates them on a 5-star scale. Helmets with 5 stars provide the best protection, while 1-star helmets should be avoided. You can check any helmet’s rating at helmet.beam.vt.edu. The site is the most trusted independent source for helmet safety data.

Get the fit right

A properly fitted helmet sits level on your head, covers your forehead, and feels snug without pressure points. The straps should form a V under each ear, and the chin strap should allow one finger between the strap and your chin. Most helmets come with a universal fit system that adjusts to your head shape with a dial.

Replace your helmet after any impact

EPS foam compresses on impact and cannot protect you twice. Replace your helmet after any crash, even if the damage is not visible. Also replace helmets every 5-7 years, as the foam and plastics degrade over time. Most manufacturers print the manufacture date inside the helmet.

Safety Technology Explained: MIPS, Koroyd, KinetiCore

Modern bike helmets use several technologies to reduce head injury risk. Understanding these technologies helps you make an informed buying decision.

MIPS (Multi-directional Impact Protection System)

MIPS adds a low-friction layer between the EPS foam and your head. During an angled impact, this layer allows the helmet to rotate slightly relative to your head, which reduces rotational forces on the brain. MIPS is the most common rotational protection system and is found on most mid-range and premium helmets.

Koroyd

Koroyd is a honeycomb of welded polymer tubes that crumples on impact in a controlled way. It absorbs more energy than solid EPS foam and runs cooler because air flows through the tubes. Smith uses zonal Koroyd in some helmets and complete Koroyd coverage in premium models.

KinetiCore

KinetiCore is Lazer proprietary rotational protection system. It uses controlled crumping zones inside the EPS foam to absorb rotational energy. KinetiCore is lighter than MIPS and does not add bulk to the helmet.

WaveCel

WaveCel is Bontrager’s cellular structure that lines the inside of the helmet. It flexes and crumples on impact to absorb both linear and rotational forces. WaveCel is found on Bontrager helmets across multiple price points.

Helmet Fit and Sizing Guide

A poorly fitting helmet is almost as dangerous as no helmet at all. Follow these steps to get the right fit.

Step 1: Measure your head

Use a soft measuring tape to measure the circumference of your head about 1 inch above your eyebrows. This is your helmet size in centimeters. Most adult helmets fit heads between 54-62cm.

Step 2: Check the shape

Helmets come in different shapes: round, oval, and intermediate. Round heads fit best in Giro, Bell, and some Smith models. Oval heads fit best in Specialized, POC, and some Lazer models. Try a helmet on before buying if possible.

Step 3: Adjust the fit system

Use the rear dial to adjust the internal fit system. The helmet should feel snug without pressure points. It should not move side to side or front to back when you shake your head.

Step 4: Adjust the straps

The side straps should form a V just below each ear. The chin strap should be snug but comfortable, allowing one finger between the strap and your chin. Loose straps compromise protection.

Step 5: Test the fit

With the straps adjusted, the helmet should sit level on your head and cover your forehead. It should not tilt back, exposing your forehead, or tilt forward, blocking your vision. Shake your head gently. If the helmet shifts, readjust.
