What to Look for While Purchasing the Best Mountain Bike Helmet for Kids?

Here is a quick list of the critical factors to look for when choosing the best MTB helmet for children between the ages of 5 and 12 girls and boys:


MTB helmets are made to fit various head sizes, and they often list their measurements in centimetres. While riding with an MTB helmet that is too big or too small may be manageable, the real problem comes in the event of an accident.

The MTB helmet on your youngster should fit snugly but not too tightly. Additionally, a properly fitting MTB helmet should allow the front to rest no higher than an inch above your eyebrows and sit snugly on your head. As a result, your forehead and the back of your head are both protected by the helmet.

Later on, as your youngster gets older, fit can become important. If your child has grown connected to their bike helmet, investing in one they can use for many years could be wise.


Furthermore, kids MTB helmets are available in various sizes, with circumferences ranging from 45 to 58 cm. Try to take measurements of your child’s head before choosing an MTB helmet.

When you have the circumference, compare it to the range the MTB helmet will accommodate. The ideal position is in the middle with plenty of room to move the helmet as necessary.


Weight can be considered when choosing your child’s first MTB Helmet based on age and size.

Since most bike helmets come in various sizes, they frequently look big or small on the wearer’s head. Your child may feel much weighed down and uncomfortable if their helmet is too big for their head.

Ensure you know the MTB helmet’s weight before purchasing it online or in person.

Fortunately, the United States requires that all bike helmets meet a safety standard set by the CPSC. Always check the CPSC certification of any MTB helmet you purchase. Consider purchasing a bike helmet with MIPS certification to take things a step further.

MIPS is a system that can significantly lessen injury in slower impacts and provides greater brain injury protection for your child. An MTB helmet must snugly fit your youngster and be CPSC certified as safe.

Even the safest MTB helmet in the world won’t help if it doesn’t fit your child’s head properly. Additionally, you shouldn’t get a lightweight XC helmet that covers a small amount of your child’s head if they are riding challenging Downhill courses.

On the other hand, if your child mainly uses cross-country trails, a full-face helmet may be overkill because it can obstruct their vision more than a better-suited helmet.


Sadly, riding all day might cause a lot of heat buildup in your child’s head. Look for a helmet that features a ventilation system. Fortunately, most children’s mountain bike helmets have numerous vents to allow air to circulate.


It’s likely that when your youngster receives their first MTB helmet, they may need to make many changes until they discover the ideal fit.

The rider may also tighten the inner shell or brace of most modern bike helmets for a secure fit using a system at the back of the helmet. This mechanism keeps the helmet on your child’s head and gives them a feeling of more security.

Kid’s Choice

Kids MTB helmets, like most of the equipment your child will need, are available in various sizes and designs. Always consider your child’s preferences when looking for a new helmet because you are the one who knows them best.

It’s a fantastic idea to let them choose their new MTB helmet so they’ll be happier using it for a longer time.

Frequently Asked Questions (FAQs)

Does helmet size matter?

Your children face a higher risk of serious brain injuries if they wear a helmet that fits too loosely. On the other side, a helmet that is too tiny or too tightly fitted would be uncomfortable as well as potentially dangerous.

Is a full-face helmet really necessary for your child?

Too many overprotective parents insist their children wear full-face helmets when cycling around their neighbourhood. Give your kid a classic bike helmet so they can feel safe when riding about town or even on easy trails in the mountains.

Helmets with full faces are hot and bulky. It is uncomfortable to wear them for extended periods. Obviously, your youngster needs a full-face helmet if they are riding downhill mountain bikes, racing BMX, or jumping off jumps. Just don’t put a child through unnecessary suffering.

Should young riders wear helmets?

Bicycle helmets have been proven to minimize the risk of brain injury by as much as 85%, according to safe kids. Therefore, kids and adults must always wear helmets while riding bicycles. Since 1999, there has been a 54% decrease in accidents using helmets.

What occurs if children don’t wear helmets?

Children and teenagers participating in horseback riding and other equestrian sports most frequently experience concussions. Additionally, research indicates that youngsters not wearing helmets were more likely to get serious brain injuries with internal bleeding.

My Final Thoughts

In the end, many kids’ mountain bike helmet options are available. You will surely have a positive experience if you follow the safety guidelines and do thorough research before making a purchase.

Try on a few helmets at your local sports store or bike shop if you can. Find a trustworthy seller or marketplace allowing you to return the item without cost if you purchase it online.
