Kids’ Bikes Buyer’s Guide

With so many brands, models and varieties out there, choosing a kid’s bike that meets your child’s needs and has the wow factor can be tough. This buyer’s guide is designed to help you make that decision, covering all the key considerations from design and size to price and features.

Why should I buy my child a bike?

Bikes are one of the best gifts that money can buy. Giving kids a whole new level of independence, bikes are a great way to get them away from the TV or games console and out exploring the world. They’ll even stay fit and healthy while they're at it! Cycling is also a great way for families to bond, whether it's on a Sunday afternoon bike ride or a car-free commute to school.

What size kids' bike do I need?

Getting the right size bike is important for both the comfort and safety of your child. Some kids grow faster than others and some just want to be comfortable as they ride, with recommended high saddles or low handlebars the opposite of what they prefer.

The best way to get the right size bike for your child is to get them to ride it. Just pop into your local Halfords store and ask for some help from one of our bike experts – we'll happily set your kid up with a short test ride to make sure they're happy.

If the bike’s going to be a present that you want to keep secret, then you'll need to measure your child’s height and match it up to the correct wheel size (unlike with adult bikes, where the frame dictates the size, the sizing for kids’ bikes is done by wheel diameter).

The easiest way to get the right wheel size if you're buying online is to check out our guide to finding the right size bike for your kids. It has all the information you'll need, plus you can simply match up your child's height to the right bike wheel size. (Just bear in mind that every child is different and so this is only intended as a guide.)

We’ve included our size chart below for your convenience.

Kids’ bike types: which one should I choose?

Balance bike (First bike)

First-time riders may struggle to ride a 'traditional' bike with pedals and gears, so a balance bike may be a better option. With nothing getting in the way, kids can push themselves along using their feet and practice taking their feet off the ground when they're going fast enough, teaching them all about balance and maintaining speed.

Shop balance bikes

Kids’ stabiliser bikes

Kids’ stabiliser bikes are a more traditional option when teaching kids how to ride a bike. Your child can merrily pedal away without the risk of losing balance and taking a tumble. As your child grows in confidence, the stabilisers can be removed, and they can practice balancing all by themselves.

Junior bikes

Junior bikes are designed for younger cyclists who have mastered the art of balance, spanning between the ages of 6 – 12 years old. We have a range of junior mountain bikes to get them set off on their cycling adventures. If you are unsure of the right size bike for your child, take a look at our kids bike size guide.

Safe cycling for kids

Cycling is generally a safe activity, but there are a few hazards to be aware of. Investing in a few safety accessories as soon as you decide which bike to buy will mean your kids are protected from day one.


Without a doubt, a helmet is the most important piece of safety equipment that you can buy. Helmets can prevent serious head injuries, and they'll go a long way to preventing nasty cuts and bruises too. Make sure your helmet fits your child's head correctly and isn't too large or small – and consider buying an adjustable helmet so it can be adjusted as they grow.

Check out our Kids’ Bike Helmet Buyer’s Guide for more information about how to find and fit the perfect helmet.

Protective pads and gloves

Knee and elbow pads are particularly helpful when your little one is learning to ride, as they’ll protect against any bumps and scrapes.

Gloves provide cushioning against the handlebars, help to reduce vibrations for a more comfortable ride and also provide added protection for little fingers.

Shop knee and elbow pads

Lights and reflectors

Bike lights are a legal requirement if your child will be riding after dark, but they're also great for making sure everyone on the road or pavement can see exactly where they are. Reflectors are installed on all Halfords bikes as standard, but there's no harm at all in attaching as many as possible to give other road users the best chance of seeing your child.

Shop bike lights and reflectors

Hi vis clothing and accessories

Help your kids to stay safe and seen in all light conditions by investing in some hi vis clothing and accessories. A reflective wrist band or hi vis kid’s vest will provide plenty of reflective surfaces and fluorescent material to make them visible on even the darkest of nights.

As well as teaching kids how to be polite with a gentle ring of their bell, bells can also be a way to avoid any embarrassing collisions if a learner is stru ggling to keep their bike under control! They could even end up being the thing that allows drivers or other cyclists to stop in time.

Just select the ‘bike build’ option at the online checkout or ask a Halfords team member at the till.

Choosing the best kids’ bike

So, how do you know whether you’ve found the best kids’ bike for your little one? Well, start with how the bike feels. If they’re comfortable and moving around on it easily, you’re onto a winner. If, however, they feel that the bike doesn’t fit at all, you might want to look to it swapped out for a better fitting bike.

There’s a huge middle ground between those two extremes that can be covered by simple adjustments to the bike. Check out our guide on finding the right size for more information.

Ultimately, you’ll know you’ve chosen the right bike if your kid falls in love with it. For most kids, a bike is symbol of independence; it’s the first large item they own, and it can give them a sense of freedom and joy. Not to mention that cycling is a fun skill to learn and master!

You should now be up to speed on the best bikes for kids! Just remember, if you're still struggling to pick the right kids’ bike or you have questions about sizing or bike features, then just ask – we've got bike experts in every Halfords store who'll be happy to help.
