Ensuring the Fit Is Right

  • Let your child wear the helmet: Start by placing the helmet square on your child’s head. It has to sit on the top, not too far back or forward.
  • Check the space: Use two of your fingers, and place them between the helmet and your child’s eyebrows. There should be no more or less than the width of two fingers in this space.
  • Ensure it’s snug: Grab it gently and try to move it from side to side — if it doesn’t budge, the size is right. If it moves and feels loose, it’s too big, and you should either insert padding or replace it.
  • Check the sides: Look at both sides, and check that the straps surrounding the ear create a “Y” shape. If the form is off, use the strap adjuster to tighten or loosen the fit.
  • Test the strap: Buckle the strap and tighten it until you can fit no more than one finger. You can also ask your child to open their mouth as wide as possible — if the helmet pulls down, it’s okay. If not, it’s too loose, and you should tighten the strap.

How to Choose a Kids’ Bike Helmet

Here are some tips to finding a safe helmet your child won’t fight you about wearing while they are out popping wheelies.

The Size

If a bike helmet is either too small or big, it can’t protect the head as it’s supposed to.

Most manufacturers list sizes according to age but this isn’t always accurate since head sizes vary between children. It’s necessary to measure the head to find the correct size.

You also have to take into consideration the shape of your child’s head. Some are narrow, while others are wide. Helmets are the same — there are different styles to cater to variously sized heads.

If you buy online, we recommend looking at user reviews before making a decision — many parents write detailed reports, giving you an idea of the fit.

Adjustability

When you manage to find the right size, the helmet may still sit a little wobbly on your child’s head. A useful feature is a dial-adjust system to tweak those last millimeters. These sit at the back of the helmet and tighten the inner cage up.

Most kids’ bike helmets add these to cater to growing heads. If the helmet doesn’t have a dial-adjust, it’s likely to include thicker, removable padding. These aren’t as desirable as the dial, but it’s doable.

A Good Buckle

As a child grows, their helmet may pinch under the chin. Your child should know how to adjust the buckle. This will reduce the chance of them placing it on their head and leaving the straps loose because it’s uncomfortable fastened.

There are two types of buckles — the old-school buckle and the newer magnetic type. Magnetic fasteners are still a feature only included in luxury helmets. They do eliminate the chance of pinching, though, so they could be worth the investment.

Lightweight

A light helmet is best as a heavy one can weigh your child down and tire them. When you get into the bigger sizes though, the helmets generally weigh more, so if your child has a large head, it’s something to be aware of. Extra stuff such as novelty ears or other accessories can also add to the weight.

Your Child’s Activities

Not all bike helmets are suitable for other activities, such as skateboarding or scootering. If your child takes part in other pursuits requiring a helmet, look for one that is dual certified. These are designed to keep your child’s head safe in various situations.


The Best Kids Bike Helmets of 2021

Here are 10 great bike helmets for kids to consider.

1. Raskullz Mohawk Child Bike Helmet

Best LED Kids’ Bike Helmet

Raskullz has created an ideal helmet for boys — it has a cool look that will encourage your kid to wear it.

The main feature on the helmet is the fin mohawk at the top. It illuminates via five LED lights. Your child can choose between steady or flashing.

The mohawk helmet is available in multiple colors and designs. It comes in one adjustable size suitable for children aged 5 to 8, measuring 19.68 to 21.25 inches. You can fit it snug around their head using the included sliders.

For the construction, Raskullz used EPS for the inner shell to absorb impact shocks. The soft pads inside ensure a comfortable fit. Your child will love wearing it.

The chin strap also allows for adjustments to prevent the helmet from slipping off while riding fast. At the top, there is a row of ventilation holes, keeping the noggin cool on warm days.

The mohawk requires batteries to light up, but these are included. The LED lights will shut off automatically after a while.

  • Fun and unique colors and designs.

To further enhance well-being, there are 20 ventilation holes at the top — they will bring a breeze through to prevent the head from overheating.

The Thrasher is incredibly lightweight, which is mostly due to its three-piece micro-shell. It weighs a mere 10 ounces, so it won’t slow your child down.

The shell is also durable and can withstand high impacts in the case of a crash. You can ensure it is secured correctly by using the adjustable side straps.

When to Replace a Kids’ Bike Helmet

  • Outgrown the size: This one is obvious — once the helmet sits too snugly on your child’s head, it’s time for a replacement.
  • Dropped helmet: Experts recommend you replace the helmet after it has fallen on concrete or other hard surfaces (2). Even a drop can cause significant damage to the materials, reducing their effectiveness during an actual crash.
  • Following a crash: If your child wore the helmet in an accident where it took the impact, it’s best to replace it. Even if there are no visible damages to the exterior, small fractures could have occurred on the inside.

Mind Hand-Me-Downs

If you’re offered a used helmet, be cautious. If the previous owner used it often or crashed while wearing it, it won’t protect your child. Also if it’s old, the material is brittle and can easily break.

Mind the Head

A helmet can significantly reduce the chances of severe head injuries during a crash. It should be safety certified to fit the activity it is used for.

Finding the best kids’ bike helmet to protect your child is essential. Ensure that the fit is right, and that it’s lightweight and adjustable.

Once your child is wearing the helmet, have them shake their head. If the helmet moves excessively from side to side, it’s too big.

Remember to require they use it every time they take their bike for a spin.
