Quick picks: for parents in a hurry

Not got time to browse? Here are our top three picks of baby and toddler helmets, to help you make a quick decision and get on with your day.

  • Best budget option: B'Twin Baby Cycle Helmet 500 (£14.99) - good quality, small enough for babies, and affordable.
  • Best designs: Hornit Helmet (£29.99) - huge array of colours and patterns to keep them happy.
  • Best overall protection: Specialized Mio MIPS (£40.00) - includes MIPS rotational impact protection.

Top tips: to help you decide

We’ve provided a lot more in-depth buying advice at the bottom of this article, but if you don’t have much time, these are the absolute essentials you should know before choosing the best bike helmet for your baby or toddler.

  • Size: An ill-fitting helmet won’t provide any protection, so it is crucial that you measure your child’s head and buy them the right size. Here’s our guide to how to measure your child’s head for a bike helmet.
  • Weight: Depending on which brand and model you go for, your child’s helmet could weigh anything between 170g and 340g. Between a one year-old and three year-old, there’s a huge difference in the strength of their necks, so while size is important, so is weight.
  • Shape: While of course, all helmets are round, there are slight differences in designs. It’s not always important, but if your child sits in a bike seat or trailer, they’d benefit from a design that’s flatter at the back, so they can lean their head back comfortably.
  • Protection: All the helmets listed here meet the required safety standards, but some have more protection than others, whether that’s more coverage around the neck and temples, or the inclusion of MIPS technology. Extra protection adds to the price, so think about much they realistically need.
  • Design: From a practical standpoint, the colour or pattern of a helmet doesn’t matter, but when it comes to getting your little one to wear it, taking into account how it looks can be very useful. Many brands offer lots of colour options and fun patterns, so find something they’ll love wearing.

How to choose from the best bike helmets for babies and toddlers

If you’re still in need of a bit of guidance before making a purchase, then here are some answers to frequently asked questions.

Is it safe for a baby to wear a helmet while sitting in a bike seat or trailer?

Yes, it is safe for a baby to wear a helmet while sitting in a bike seat or trailer. It’s crucial that the helmet fits well, is lightweight, and doesn’t strain your baby's neck. Helmets designed for use with bike seats — rear and front mounted — and trailers, often have a flatter back to provide better comfort when they lean their head back against the headrest.

At what age should a baby get a bike helmet?

Babies tend to be ready to start riding in a bike seat or trailer from around 9 to 12 months old. This age range can vary depending on their physical development, particularly their neck strength and ability to sit up independently. There are two helmets in this guide that are suitable for babies: the B’Twin Baby Cycle Helmet 500 and the Giro Scamp II. As we’ve said above, proper size and fit is crucial, not only for your baby’s safety, but also for their comfort and — by extension — their willingness to wear it. So the biggest question to answer is: is your child’s bike helmet fitted correctly?

What size helmet does a 1 year-old need?

Even as young as one, babies’ heads will vary in size. A one year-old generally needs a helmet that fits a head circumference of 44-49 cm, which is a pretty wide bracket, especially at this age. That’s why it’s still important to measure their head to determine the right size helmet for them. Follow our guidance on how to measure your child’s head for a bike helmet, and use your measurement to choose a helmet with an appropriate adjustable fit range. Many helmets come with adjustable straps and dials to fine-tune the fit, so you can make sure it’s secure and comfortable as your child grows.

How do I choose a bike helmet for my toddler?

There are many factors to consider when choosing the best bike helmet for your baby or toddler. As a minimum, be sure that the helmet has been rigorously tested and meets UK safety standards (more on these below). All the helmets recommended here, and sold by bike shops and major retailers, will meet these standards.

Measure your toddler’s head to find the correct size, and look for a helmet with adjustable straps and a fit system (like a dial or cradle) to customise the fit. Prioritise helmets that offer good ventilation to keep their head cool, and a light weight. 

You also might want to find a fun and colourful design that appeals to them, to encourage them to wear it regularly.

How much should I spend on a bike helmet for a baby or toddler?

How much you spend on your child’s helmet will depend on several factors, like materials and technology used, adjustability, different design options, and overall weight. The options we’ve listed here range from £14.99 to £44.99, and all the helmets we recommend are of good quality and meet the minimum safety requirements.

If you can spend more, then for the higher price you’ll get more advanced protection technology like MIPS (Multi-directional Impact Protection System), along with other details that make the helmet more comfortable to wear, like magnetic buckles.

What is MIPS technology and does my child need it?

MIPS stands for Multi-directional Impact Protection System. It’s an advanced safety technology designed to reduce rotational forces on the brain during angled impacts. In other words, it helps protect the brain from twisting injuries during a crash by allowing the helmet to move slightly on impact, absorbing some of the force.

It does this by adding an extra layer inside the helmet that allows the outer shell to move slightly during a crash, providing additional protection. While MIPS isn’t essential, it does offer enhanced safety, so some parents prefer to have it included in their children’s helmets. MIPS does add more to the price tag, though. If there’s room in your budget, opting for a helmet with MIPS can provide extra peace of mind around your child’s safety, but a cheaper helmet without MIPS will still provide adequate protection and will have passed numerous safety tests. For more on this topic, take a look at our article, does my child need MIPS in their helmet?

What are all the different bike helmet safety standards?

In the UK, bike helmets must comply with the EN 1078 safety standard as a minimum. There are other standards and testing that can be carried out by some brands, and we’ve written a full guide to the safety standards to look out for when buying a kids’ bike helmet.

Should my baby or toddler wear a full face helmet?

No, we don’t recommend putting a full face helmet on a baby or toddler. They are far too heavy for their little necks to support, and not designed for such young children. It’s better to opt for a helmet that’s purpose built for a baby or toddler, and designed to be comfortable for them to wear, than to give them something very large and heavy, no matter how protective it may seem.

We’ve got an article on this that explains the risk, so read this if you want some more detail: does my child need a full face helmet when cycling?
