There are so many great things about going on a family bike ride. As well as getting some all-important exercise, it promotes family bonding, is environmentally-friendly and a great stress-reliever for all involved.


But a quality cycle helmet is an absolute must in order to keep your child safe whether riding on the road, through the woods or in the skate park.

We’ve trawled expert review sites and the Mumsnet forums to find out which kids’ bike helmets our users recommend and reveal our top picks below.

Here are the best kids’ bike helmets to buy in 2021.

1. Best overall kids’ bike helmet: Bontrager Jet WaveCel Youth Helmet

Bontrager Jet WaveCel Youth Helmet

Price: £58 | Buy now from Evans Cycles

“Bontrager has a great slogan for their WaveCel technology: ‘You Only Have One Brain.’ My DD also had a very minor fall on her bike coming out of school at age seven, and her helmet cracked from the force. We use free or secondhand bikes but buy gold-standard helmets, and now I don't regret it at all.” Confrontayshunme

Bontrager’s youth bike helmet tops our list for the best kids’ bike helmet, mainly for its unique and relatively new safety feature.

WaveCel, a collapsible cellular structure that lines the inside of the helmet, keeps young riders safe from injury and helps to assure parents that their little ones are in expert hands. It’s designed to look like a skater helmet and this, coupled with the bright lime green colourway, makes it popular among kids too.

How do you choose a bike helmet for a child?

There are a number of things you should consider when purchasing a child’s bike helmet.

  • Size and fit: It’s crucial that you buy a helmet that’s the right size and a good fit for your child. If the bike helmet doesn’t fit properly, then this means your child won’t be fully protected. You can use a tape measure to measure around your child’s head to help you order the correct size if shopping online. If you’re unsure, go to Halfords or your local bike shop for help and advice.
  • Safety features: Do you want a helmet which boasts extra safety features, such as an LED light if riding at night? Or a bluetooth helmet which can send a safety alert to emergency contacts?
  • Design and pattern: Does your child like vibrant colours or something a bit more muted? Spider-man? Dinosaurs? Frozen? Make sure you pick a helmet that your child will like and will put on and wear with minimal fuss.
  • Price: Always set a budget! The cost of kids’ cycling helmets vary wildly. Think about how often your child goes out on their bike and consider whether it is worth paying out for a top-of-the-range branded helmet.

What size helmet should my child wear?

When buying a kids’ bike helmet, you need to know your child’s head circumference. 

Measure around your child’s forehead, just above the eyebrows, using a tape measure and compare this measurement to the helmet manufacturer’s sizing table and pick an appropriately sized helmet for your child.

As a general guide: 46cm fits a 12-month-old, 48cm fits a two-year-old, 51cm is suitable for three- to five-year-olds, 53cm for six to 10 years, and 56cm for 11+ years.

Don’t be tempted to size up and pick a helmet for your child to grow into. A bike helmet needs to fit correctly in order to provide adequate protection.

The helmet should fit snugly and shouldn’t move from side to side. A well-fitting helmet sits low on the forehead, sitting just one or two finger-widths above the eyebrows. The side straps should form a Y shape and meet below the ear.  When you fasten the chin strap, you should not be able to fit any more than one finger under the strap.

Which kids’ bike helmet is best?

Mumsnet users rate the Bontrager Jet WaveCel Youth Helmet as the best overall kids’ bike helmet, with a gold star for its unique safety feature, a collapsible cellular structure that lines the inside of the helmet, which offers peace of mind to parents. With its bright green colour and skater helmet design, it appeals to kids too.
