Best kids' bike helmets: A buyer's guide
The best kid's bike helmets will help keep them safe as they ride. We've put together a buyer's guide on what to look for when choosing

Kids' bike helmets need to keep them safe, be comfortable and fit well. Choosing one of the best bike helmet for road cycling for yourself can be a simple affair; with so much choice you never have to worry about finding something that suits your needs.
When it comes to choosing a kids' helmet, there's a little less choice, and even less information available. However, if your child is already a confident rider or you're setting about teaching your child to ride a bike — be it an early start on a balance bike, or a later introduction on a kids' pedal bike — it's a good idea to invest in a quality children's helmet.
Kids' bike helmets adhere to the same safety guidelines that your high-end racing lid does — and to do so they'll have been tested in some pretty extreme scenarios — so you know they'll provide plenty of coverage and safety, even from an entry-level price point.
Spending more will get your mini-shredder a lighter lid with better ventilation. This will become more important as your little one becomes more interested in cycling, riding further or longer, where they are more likely to get hot and bothered.
Some more expensive kids' cycle helmets gain their extra value simply from looking a little bit cooler. Although you probably don't want to shell out too much purely for swanky patterns, it's worth remembering that as children get older, the helmet can become a barrier to riding, and thus it may well be worth spending a little bit more on one they like.

Hornit Mini LIDS kids bike helmet
Specifications
Reasons to buy
Reasons to avoid
Designed to be a bit more universal (and cooler) than the majority of bike-specific helmets, the Hornit Mini range is inspired by skateboarding and is perfect if your kids ride scooters, skateboards, or other wheeled devices in addition to their bikes.
The Hornit helmets are tested to the CSCP (US) and EN1078 (Europe) safety standards and feature super comfortable padding to ensure children will enjoy wearing the Hornit Mini.
Two sizes are available to fit everyone from toddlers to teenagers (and beyond) and all are fully adjustable and well-ventilated thanks to eleven vents. A neat LED rear light is fitted as standard for a little extra peace of mind in low light conditions.
The Hornit Mini range is huge and there are colours and designs to suit absolutely anything your children might be in to from the Llama design above to an understated Stealth Black version.
Giro Hale kids bike helmet
Specifications
Reasons to buy
Reasons to avoid
Coming in a variety of colours, this helmet will not only look the part for any young intrepid cyclist, but thanks to its In-Mould construction, and EPS liner, it will protect them too. In the US, the helmet comes with MIPS.
Its visor is removable and the high quality padding dries quickly so it's a good option for kids that are looking to go a bit faster and push themselves.
The biggest problem with children is that they grow so fast and the idea of buying a new helmet every couple of months is tiresome. But thankfully this comes with Giro's Roc Loc Sport dial-based retention system allowing head sizes from 50cm up to 57cm to fit with ease.
Lazer J1 kids bike helmet
Specifications
Reasons to buy
Reasons to avoid
With 19 vents, an integrated visor, and Lazer's Advance Turn Fit retention system, the J1 Helmet has almost the same level of features we'd expect from an adult lid.
It's made with an In-Mould manufacturing process, so the outer shell won't separate from the foam over time, and will keep your little one's noggin intact after a spill.
It comes in a range of colours, including a flames graphic, and is compatible with Lazer's TS+ rear LED light, so if they are out late battling Demogorgons, they will still be visible once the sun goes down.
Bell Sidetrack II MIPS kids bike helmet
Specifications
Reasons to buy
If your child is a bit older and is looking to take on some serious riding, whether that be off or on road, then the Bell Sidetracked II MIPS is a good transition before they start wearing adult helmets, although there's a smaller size option available for younger kids too.
The helmet has 14 vents and comes complete with MIPS technology which uses a movable inner liner designed to more efficiently dissipate impact in a crash. You'll find this same technology in the top of the range helmets from just about every brand for its claimed ability to absorb rotational forces before they reach the brain.
Kiddimoto's helmets take a skate style, with a more enclosed design for good head protection. The two sizes cover ages from 2 up to 10 and there's lots of padding for comfort, while Kiddimoto offers a 2 year guarantee.
Don't fancy dots? There are loads of different designs and Kiddimoto sells a full-face helmet too if off-road antics are getting too hairy.
Specialized Mio MIPS kids bike helmet
Specifications
Reasons to buy
Reasons to avoid
For the kids who haven't quite graduated from their balance bikes, the Specialized Mio MIPS helmet is designed for smaller heads and perfect for toddlers.
Made with an In-Mould construction, there is plenty of rear coverage, and a magnetic buckle to prevent nasty under the chin pinches. Inside is a MIPS liner and Specialized's SC fit system which allows for head sizes from 46-51cm. It comes in a range of funky styles so there's bound to be one your child loves.
Bern Bandito kids bike helmet
Specifications
Reasons to buy
Reasons to avoid
Extreme sports company Bern gives a slightly different offering with their kids' lids. For a slightly older child, this Bandito helmet is a good fit for ages 8 up to 15.
Designed to be used on the bike and on ski slopes, the vents can be plugged with an interior liner — great if the temperature drops or you want to do some alpine skiing. There's no obvious difference between the Bandito and Bandita apart from colour offerings.
The MET Elfo helmet has been specially designed with extra protection of the fontanelle - the most sensitive part of a child's developing head. The helmet is built to be comfortable in a child seat and there's an integrated LED at the rear. There's even a built-in bug net to keep insects away.
For larger kids, the Genio helmet has the same design and colour options and goes from 52cm up to 57cm.
