Buying your child a new bike? Finding it hard to pick the best one? Relax, we've put together a simple guide to help you choose wisely…
The most important factors to consider are your child's age, height and ability. The weight of the bike will also affect its handling, and bikes at the very low end of the price spectrum are often the heaviest.
A simple guide to kids' bike sizes
The first question is ‘what size bike should I get for my child?’
For younger children of preschool age, balance bikes are perfect. These are simple bikes without pedals or gears that the child pushes along with their feet while sat in the saddle.
The simple set-up means that children get the feel of pushing off and balancing on the bike while it’s moving, which also means the transition to a pedal bike is much quicker — and they probably won’t need stabilizers when the time comes either!
As children grow, they will of course need bigger bikes. Children’s bikes grow in wheel size as well as frame size: having smaller wheels for smaller riders makes the bikes easier to handle.
Aged 4 to 6
For children aged four to six, or roughly 105cm–115cm / 3’5”–3’9”, go for a bike with 14- to 16-inch wheels. Most of these are simple bikes with pedals and brakes, and many come with a small range of gears.
Aged 7 to 10
For 7- to 10-year-olds (height 115cm–135cm / 3’9”–4’5”) choose a bike with 18- or 20-inch wheels. You’ll also start to see a wider range of gears appearing at this price point, and you may find bikes with front suspension, which are more suitable for rough terrain.
Aged 10 to 13
Children aged between 10- and 13-years-old (height 135cm–150cm / 4’5”–5’) will usually move on to a 24-inch wheel bike and at this point you’re looking at a bike that’s essentially a smaller version of an adult bike.
You’ll also start to see different types of bike, from junior-sized road bikes and mountain bikes to hybrid/leisure bikes. Choose a bike type that’s going to suit the majority of the riding your child will be doing: if it’s mostly going to be off-road, wide tyres with a grippy tread is a good choice, for example.
For teenagers upwards, you’re going to be looking at adult bikes in smaller sizes. There are smaller wheel-size options for junior road bikes, such as 650b, though most bikes will have 26-inch, 27.5-inch or 700c wheels.
Bear in mind that these sizes are a guideline only. If your child is taller or smaller than average, or more or less confident, they may be better off on a different size. If in doubt, talk to your local bike shop.
Also, although it can be tempting to go for a bigger bike that your child can ‘grow into’, this is best avoided. A bike that’s too big will be hard to handle and steer.
Of course, you’ll need to teach them to ride too, so check out our simple guide that should get them pedalling away independently in around 30 minutes.
Best bikes and balance bikes for children aged 1 to 4
Once your child is up, toddling around and stable on two feet, they’re ready for their first set of wheels.
There are two options at this point: a balance bike or a trike.
Trikes might seem like an attractive option, because they are stable and allow kids to start peddling along themselves, but in our opinion balance bikes are a much better choice.
This is because a balance bike will help your child develop key skills such as balance and steering first, so they are more likely to make the transition to a pedal-powered bike quickly and without needing stabilisers.
For younger kids, you’re usually looking at a wheel size of 12 inches. There are also some pedal-powered options for two- to four-year-olds, and many will come with brakes: either lever-operated ones or coaster brakes that work by back-pedalling, and sometimes both.
Strider 12 Sport Balance Bike
The Strider Sport Balance bike is suitable for children aged 18 months up to four or five years. It features a long seatpost that can be lowered fully or raised high to fit your child.
A durable steel frame should withstand some rough treatment, and the tyres are designed to be puncture proof.
We like the built-in footrests, so when your child gets the hang of gliding along on the bike they’ve got somewhere to rest their feet. Perfect preparation for moving on to pedals.
The bike is also designed to allow you to adjust the saddle and handlebar height without needing tools.

Best bikes for kids aged 4 to 6
When your child is a bit older and taller they can move to a bike with 14- or 16-inch wheels.
If the bike was already supplied with stabilisers, and your child is confident riding without them, then remove them ASAP.
The key things to look at here are a low weight, so the child is able to handle the bike, and brakes that have an easy action and small size to suit smaller hands.
Most kids' bikes at this price bracket should allow you to adjust the reach to the brakes. Many also have coaster brakes rather than lever-operated brakes, which are operated by back-pedalling.
Trek Precaliber 16
The Precaliber is a rugged bike with an aluminium frame designed for smaller riders. It comes fitted with a chainguard and stabiliser, the latter of which you may want to remove if your child has been confidently gliding along on a balance bike.
It’s also fitted with both handlebar brakes and a coaster brake, which operates by back-pedalling, and 16-inch wheels suitable for kids aged about five to six years old.

Best bikes for kids aged 7 to 10
Look for bikes with 18- to 20-inch wheels. At this point you’ll start to see more gearing options, and lever-operated brakes only.
You’ll also start to see suspension beginning to make an appearance, usually front suspension forks only.
Bear in mind that cheaper suspension bikes can be heavier than their non-suspension alternatives, and that if the bike is to be ridden off-road, some good-quality, wide, puncture-resistant tyres should be a higher priority.

Best bikes for kids aged 13+
For teenagers, you’ll be able to pick from a wide range of bikes including small sizes of adult bikes. You can also get junior versions of bikes that have a slightly smaller wheel size, such as road bikes with 650b wheels rather than the adult 700c wheels, and mountain bikes with 26-inch wheels rather than the now more common 27.5-inch wheels or even 29ers.
You may want to consult (stealthily if it’s supposed to be a surprise purchase) with your child about the type, brand and colour of bike they’re after.
If your teenager is getting really into their sport, there are now plenty of high-quality race-ready road and mountain bikes that will cultivate their competitive edge produced by brands such as Commencal and Isla Bikes, and we’ve included a few of these below.
