Looking at kids’ bikes and don’t know where to start?
We’ve put together a helpful guide to bike sizes, along with some top tips that won’t blow the budget.
Cycling is a great way to spend quality time with your kids, but first you need to get them the right bike! There’s such a big selection it can be daunting trying to find the right model.
We’ve put together a helpful guide to bike sizes, along with top tips for getting the best value, so you don’t make expensive mistakes.
General bike buying tips
- Bike weight: Many people choose bikes that are too heavy for their kids when buying models with 20” wheels or more. They’ll get more miles and more fun from a lighter bike. It’s best to opt for 13kg or less for 20” wheel bikes.
- Bike size: Buying your child a slightly oversized sweatshirt isn’t a big deal as they’ll grow into it, but buying a bike that’s too big for them to ‘grow into’ will be awkward for them and could be dangerous to ride. Remember you can always sell or pass on bikes.
- Bike helmets: Make sure you get an EN 1078 European Standard approved cycling helmet that’s the correct size. Look for the ‘CE’ logo.
- When to get their first bike: There’s no perfect age for getting on the saddle. Kids vary in their abilities and desire to get cycling. Some might start as early as three, perhaps beginning with a balance bike, while others may not be ready until they’re eight. Generally speaking, five is a good age to get on your bike.
- Bike height: Your child should be able to touch their toes on the ground comfortably when they’re sitting and their elbows shouldn’t be straight or stretched to reach the handlebars.
- Number of gears: One gear is fine for a starter bike, a three-speed gear system for second bikes and 7+ gear systems should suit pre-teens.
Kids’ BMXs vs kids’ mountain bikes
There’s no actual ‘right’ choice, it just depends on what type of bike your child wants.
BMXs are light, solid and good ‘street’ bikes They’re great for doing tricks and riding short distances on roads and in housing estates, but they’re not suitable for country tracks or cycling long distances.
Mountain bikes are more versatile. You can ride them anywhere – on roads, dirt tracks or country lanes. They’re stronger than BMX bikes but usually heavier.
12” wheel bike
Suitable for 2 to 5 year-olds or kids 85cm to 110cm tall
These bikes will have at least one brake, should have metal wheels with full ball bearings, adjustable spokes and pneumatic tyres.
They usually come in two main styles – BMX or mountain bike.
Tip: Avoid kids’ bikes that have plastic wheels with solid tyres. They’re classed as toys and may well fall apart soon after you get them!

When your kids reach the 26” wheel size remember these rules:
- For racer models, when they sit on the bike with one foot on the pedal at the bottom, they should have a slight bend in their knee. If their leg’s straight, the bike’s too big.
- For mountain bikes, when they stand with their feet on the ground they should have at least 5-10cm between them and the top tube of the frame. Again, when sitting with one foot on the pedal at the bottom, they should have a slight bend in their knee. It shouldn’t be straight.
- As bikes get taller, they also get longer. Make sure that your child can sit comfortably and reach the handlebars and gears. They should be able to reach the handlebars while still having a slight bend at the elbow. Saddles are adjustable so bikes can be tailored to fit perfectly.
- Always remember a bike which is too big can be dangerous!
