Best bike helmets for babies and toddlers

If you're taking your baby or toddler with you when you go cycling, either on a bike seat, in a trailer, or on a cargo bike you may want to invest in bike helmet for them.

Or maybe they’re zooming next to you on a balance bike and you want them to wear a helmet.

In this article we look at the best bike helmets for babies and toddlers - the smallest fits a head of just 44cm.

Sizing for bike helmets is measured as the circumference of their head, so that gives you a good starting point but there really is no substitute for trying before you buy. Find out how to measure your child's head for a bike helmet.

How to find the best helmet for your baby or toddler

For all the helmets we’re recommending, we looked at cycle helmet safety standards, how easy it is to adjust the helmet, how comfortable the helmet is, and how well they work in a seat or trailer.

It is particularly important that the clasp for the chin strap is easy to use and that the chin strap is comfortable. This will help you to tighten the straps without any tears (fingers crossed!).

If you’ve got a bike helmet for your baby or toddler already, find out if it’s fitted correctly.

If your child has got afro hair, read our article on afro hair and kids' bike helmets.

In the UK there is no legal obligation for anyone to wear a helmet, but many parents choose to use them. If you’re not sure whether you want your child to wear a helmet, read our article on things to consider when making this decision.

Can a baby or toddler wear a helmet while sitting in a bike seat or trailer?

If your little one is using a rear bike seat or a trailer then look for a helmet with a flatter back.  This will allow them to sit comfortably and not have their head pushed forward by the bulky helmet.  Some trailers do have a cut away to allow the helmet to sit a bit further back.
