Prices range widely under $350

Prices for bike helmets on Amazon.com run from $15.99 to $349.95. The median price is $34.99, so half of listings cost between $27.48 and $65.99. Most helmets cluster below $80, with only 13 listings at $80 or higher. This wide spread means you’ll find options for most budgets, but higher prices do not always mean better ratings.

What price tiers mean for buyers

The price histogram shows 14 listings under $25 and 26 at $40 or more. If you want a budget helmet, you’ll find several choices below $25. Around $30 to $40, you’ll see the most options. The data cannot show why some helmets cost more, but you may see different features or materials.

Nearly all helmets rate 4.5 stars or more

83% of listings are rated 4.5 stars or higher, and the lowest listing rating is 3.8 stars. The median for all listings is 4.6 stars. This flat spread means you’ll see little difference in star ratings, so it may help to look at features instead.

Review counts and top helmet brands

The median helmet listing has 407 ratings, but some have far more. Giro leads with 9 listings, followed by Retrospec, Schwinn, and BELL. Amazon pools ratings across sizes and colors, so counts reflect the whole product family, not just one size or color.

How We Picked the Best Bike Helmet

  • We searched Amazon.com for 'bike helmet' and removed repeated sizes, off-topic results, and multipacks as described in the Fact Library.
  • Shortlisted products needed at least 4.0 stars and 100 ratings, using Amazon's pooled rating counts for product families.
  • Best Overall goes to the highest score (star rating times log of ratings); other labels match specific needs.
  • Automated scrapers collected listing and product-page data; we did not lab-test or use the helmets.
  • There is no audience split for this keyword, so picks are not labeled by audience.

What to Look for in Bike Helmets

CPSC Certification

Bicycle helmets must meet federal safety standards to help protect riders from head injuries caused by falls or crashes. The certification means helmets pass tests for impact attenuation, retention strength, and positional stability before sale.

Good for: Anyone seeking basic head protection

Watch for: Check the product listing or label for CPSC certification before buying.

MIPS Technology

MIPS (Multi-directional Impact Protection System) adds a low-friction layer inside the helmet that may help reduce rotational forces during angled impacts. This feature is present in premium models and can offer extra impact protection.[1]

Good for: Riders wanting added head protection

Watch for: Not every helmet includes MIPS; look for it in the product name or description.

Fit and Adjustability

A proper helmet fit helps keep the helmet in place during a fall. Features like adjustable straps, dials, and sizing pads let you fine-tune fit for comfort and safety. Fit is mentioned as a key aspect in several picks.

Good for: All users, especially kids and adults with unique head shapes

Watch for: Check sizing guides and adjusters; poor fit may reduce protection.

Integrated Lights

Some helmets include built-in LED lights for better visibility in low light. This can help drivers and other cyclists see you at night or in poor weather. Picks with this feature are suited for commuting or night rides.

Good for: Commuters or those riding at night

Watch for: Check the listing for battery life and light modes if night visibility is important.

Lightweight Shell and Ventilation

A lightweight helmet with good ventilation can make rides more comfortable, especially on long trips or in hot weather. Several picks mention being lightweight or well-ventilated in reviews.

Good for: Road cyclists, commuters, and anyone riding in warm weather

Watch for: Heavier helmets may feel bulky over time; ventilation can affect comfort.

How to Use Bike Helmets

  1. Check for CPSC Certification

    Make sure the helmet meets CPSC bicycle helmet safety standards to help protect from head injuries during falls or crashes.

  2. Choose the Right Size

    Measure your head circumference about one inch above your eyebrows and use the helmet's sizing chart. A helmet that fits snugly tends to offer better protection.[2]

  3. Adjust for a Secure Fit

    Adjust the straps and retention system so the helmet stays in place and does not roll off or move during use.

  4. Try the Helmet On

    Put the helmet on and shake your head gently. It should stay in place and not block your peripheral vision.[3]

  5. Inspect Before Riding

    Check the helmet for cracks, loose parts, or missing padding before each ride.

  6. Use Only for Intended Activity

    Pick a helmet designed for bicycling. Helmets made only for skateboarding or roller hockey may not meet bicycle helmet safety requirements.[4]

6 Mistakes to Avoid

MistakeWhy it mattersDo this instead
Choosing style over safety featuresHelmets must pass specific safety tests for impact protection, retention strength, and stability to help reduce injury risk.Check for CPSC certification and safety features first.
Wearing the wrong helmet sizeA poor fit can compromise protection and make you less likely to wear the helmet. Sizing is based on head circumference.[2]Measure your head and use the sizing chart.
Not replacing helmets after a crashEPS foam liners used in most bike helmets do not recover after a hard impact and must be replaced to maintain protection.[1]Replace your helmet after any hard impact.
Assuming all helmets meet safety standardsOnly helmets certified for bicycling must meet CPSC requirements. Helmets for other sports may not provide the same protection.[4]Check that the helmet is CPSC certified for bicycling.
Thinking price always equals better protectionThe CPSC standard sets the minimum for safety.Focus on certification and fit, not just price.
Ignoring helmet instructionsHelmets come with instructions for fitting and use.Read and follow the included instructions.

Myths versus facts

Myth

All helmets sold for sports protect equally in every activity.

Fact

Helmets marketed only for skateboarding or roller hockey are not required to meet bicycle helmet safety standards.

Myth

You can keep using a helmet after a crash if it looks fine.

Fact

EPS foam liners do not recover after a hard impact, even if the shell looks undamaged. Replace your helmet after any significant impact.[1]

Myth

A more expensive helmet always means better safety.

Fact

All CPSC-certified bike helmets must meet the same safety requirements. Higher prices may reflect extra features, not more protection.[5]

Myth

A loose helmet still offers good protection.

Fact

Helmets are tested for positional stability and retention strength. A loose helmet can move or come off, reducing protection.[3]

How do you measure your head for a bike helmet?

To find your bike helmet size, measure your head's circumference about one inch above your eyebrows. Use a flexible tape measure or a piece of string, then check the length against a ruler. Helmet sizing is based on this measurement, and you can compare your number to the sizing chart shown in the listing or on the brand's website.[2]

If you fall between two sizes, you can pick a larger helmet with an adjustable dial. You can also choose the smaller size for a snug fit, or look for a different brand that fits better.[6] Fit matters because a poor fit can compromise protection or may make you less likely to wear the helmet.[2]

  • Measure just above your eyebrows for best accuracy.
  • Check each brand’s sizing chart before you buy.
  • Try the helmet on if possible to check comfort and fit.

What safety standards do bike helmets have to meet?

All bicycle helmets made after March 10, 1999, must meet the federal safety standard 16 CFR Part 1203. This standard requires helmets to pass tests for impact protection, peripheral vision, positional stability, and the strength of the retention system. These tests help protect riders from head injuries in falls or crashes.[4] Helmets must be tested both with and without any attachments the manufacturer includes. They are conditioned by exposing them to cold, heat, water, and normal room conditions before testing.[3]

Helmets marketed only for skateboarding or roller hockey are not held to bicycle helmet requirements.[4] The main goal is to reduce the chance of serious injury or death from head impacts while bicycling.[5]

  • Look for a label showing CPSC certification inside the helmet.
  • Helmets with extra features must still meet the same safety tests.
  • Helmets for other sports may not meet bike helmet standards.

Bike Helmet: Frequently Asked Questions

What is the safest bike helmet?

The safest bike helmet is one that meets the U.S. Consumer Product Safety Commission (CPSC) standard, known as 16 CFR Part 1203. All helmets marketed for bicycling in the U.S. must meet this standard. The standard includes tests for impact protection, strap strength, and stability to help protect against head injuries from falls or crashes.[4]

How do I choose the right size bike helmet?

To choose the right size bike helmet, measure your head circumference about one inch above your eyebrows. Then compare it to the sizing chart on the listing or packaging. A proper fit is important because a poor fit may reduce protection and make you less likely to wear the helmet.[2]

What is MIPS in a bike helmet?

MIPS stands for Multi-directional Impact Protection System. It is a low-friction plastic layer inside some helmets that may reduce rotational forces during angled impacts, according to one guide. The listing for the Giro Agilis MIPS includes this feature.

Are expensive bike helmets worth it?

The data cannot show why prices differ, but all bike helmets marketed for bicycling in the U.S. must meet the same CPSC safety standard for impact protection. Higher-priced helmets, like the Giro Agilis MIPS ($119.95), may offer extra features such as lighter weight or more ventilation. Some may include MIPS technology, but basic safety must meet the same federal requirements.[2]

How often should I replace my bike helmet?

One guide says you should replace a bike helmet after any significant impact, even if the outer shell looks fine. The EPS foam liner does not recover its ability to absorb energy after a crash.[1]

What certifications should a bike helmet have?

All bike helmets marketed for bicycling in the U.S. must be CPSC certified. This means they meet the federal safety standard 16 CFR Part 1203 for impact protection and other requirements.

Can I use a bike helmet for other sports?

Helmets marketed exclusively for other activities like skateboarding or roller hockey do not have to meet bicycle helmet safety requirements.

How do I clean a bike helmet?

The data does not include verified claims about cleaning bike helmets, so this cannot be answered with the supplied sources.

What features should I look for in a bike helmet?

A bike helmet should have a strong retention system, a comfortable fit, and meet CPSC certification. Some helmets offer extra features like ventilation, adjustable fit systems, visors, integrated lights, or MIPS technology according to listings and one guide.

Do bike helmets expire?

The data does not include verified claims about expiration dates for bike helmets, so this cannot be answered with the supplied sources.

Is there a difference between men's and women's bike helmets?

The data does not include verified claims about differences between men's and women's bike helmets, so this cannot be answered with the supplied sources.

What is the best bike helmet for kids?
