Kids' heads need proper protection – and our helmet is the perfect fit.

A child's bike helmet needs to fit properly and feel comfortable. And that means it needs to be carefully designed to match the exact shape of kids' heads as they grow. We studied thousands of scans of children's heads when we were designing our READY Kids' Helmet. That's how we ended up with a helmet that fits and protects perfectly at every stage of a child's development. Without slipping, wobbling, pinching or digging in. But with plenty of smart details to keep your child safe and make it easy for them to put their own helmet on and take it off again.

How do I know which helmet size my child needs?

You need to measure the circumference of your child's head to figure out which helmet size to buy. Holding a tape measure against your child's forehead, about 1 cm above their eyebrows and ears, measure all the way around their head. Check the positioning of the tape measure at the back of their head to ensure you're measuring the widest part.

Check your measurement against our sizes. If the circumference of your child's head is 48 cm, you'll need to go for XS (46–50 cm) and so on.

How do I make sure the helmet is sitting correctly?

If the helmet is too tight when your child puts it on, start by turning the size-adjustment dial to loosen off the adjustment system on the inside. Make sure the helmet is sitting level and covering your child's head properly. The front edge of the helmet should sit around 1 cm above your child's eyebrows. Turn the size-adjustment dial to tighten the ring on the inside until you're happy that the helmet is sitting nice and snugly. It shouldn't wobble when your child gently shakes their head. Finish off by fastening the chin strap clasp. Speaking of which... When first putting on the helmet, ensure the chin strap sits comfortably against the throat, checking that it's not too loose.
