Best Kids Mountain Bikes Buying Guide & FAQ
With so many great bikes to choose from, we’re confident that there’s something on our list for almost any young rider. To help you work out which option is right for you, we’ve put together this handy buying guide. Below, we run through what to look out for in a good kids’ mountain bike, how to choose the right size, and more.
What to Look for in a Mountain Bike for Kids
When it’s time to choose a mountain bike for the young rider in your life, look out for the following features:
- Correct Sizing
First and foremost, it’s vital that you choose a bike that’s properly sized for the young rider you have in mind. Riding a bike that’s too big or too small can be dangerous, not to mention needlessly difficult. We’ll run through how to choose the correct size for your child later on.
- Good Suspension
Just like their adult counterparts, kids’ mountain bikes require some impressive suspension to keep their ride as smooth as possible on rough ground. Look out for fork suspension, which is capable of handling rough and uneven surfaces. Ideally, this suspension should be paired with a relatively thick pair of tires, improving traction on loose surfaces such as dirt and gravel.
- Sturdy Brakes
It probably goes without saying, but brakes are a vital component on any bike. If your new bike is in for some rough treatment regularly, it could be worth investing in disc brakes. Otherwise, look out for linear pull brakes.
- Appropriate Gears
Trekking up steep hills can be hard work - even harder without appropriate gears to help you out. Using the proper gear can also help riders remain stable on shifting surfaces, so having a few gearing options at your fingertips is vital for any keen mountain biker. That being said, if this will be your child’s first geared bike, choosing an option with too many speeds could prove a little overwhelming. In this case, it’s usually best to look out for a bike with six to eight gears to be getting on with.
- Alloy Rims
Alloy rims aren’t just for cars - they can also support your bike tires from the taxing conditions of tracks and trails. These rims are also lightweight, keeping wheels stable without compromising on handling.
Select the Correct Kids Mountain Bike Size
Kids invariably have the annoying habit of growing, so choosing a correctly sized bike can be something of a challenge.
Since children grow at different rates, using their height, rather than their age, is the best way to pick the correct size.
Hopefully, this brief guide will help you work out which size you need:
- Children measuring 3’7” - 3’8” require a wheel size of 16”
- Children measuring 3’8” - 4’0” require a wheel size of 18”
- Children measuring 4’0” - 4’5” require a wheel size of 20”
- Children measuring 4’4” - 4’9” require a wheel size od 24”
- Children measuring 5’0” + require a wheel size of 26”
If your child is at the top end of one bracket, and the bottom of another, opt for the larger size to accommodate future growth.
Best Kids Mountain Bikes FAQ:
Q: Does a kids mountain bike need gears?
A: Generally speaking, yes.
If your child is ready to go off-road, they’re probably ready for gears. Different surfaces and inclines can be tackled using different gear settings, so they’re pretty important in an off-road bike.
Be sure that your young cyclist has mastered the basics before trying them out with gears, though - they should be able to properly balance without the help of training wheels, steer effectively, and be comfortable using hand brakes. All children are different, and will master these skills at different ages. As a rule of thumb, most children are ready to ride a bike with gears between the ages of eight and 10.
Teaching your child to ride a bike with gears is a great way to promote their coordination. If this is your child’s first encounter with a geared bike, it’s a good idea to go for an option with a maximum of 10 speeds.
Q: Are boys and girls bikes different?
A: This depends on the manufacturer. Today, many kids bikes are unisex, but those designed specifically for girls tend to have a step-through frame - traditionally used to accommodate skirts. Today, it just makes the bike a little easier to mount, which could be a boon for many children regardless of gender.
For kids, purchasing a gender specific bike isn’t necessary - they haven’t yet developed to the point where their bodies are different enough to warrant special modifications. A few companies will still insist on selling pretty pink bikes for girls, and rugged blue bikes for boys, but there’s no physical reason to choose one over the other - it all boils down to your child’s personal preference.
In adulthood, things are a little more complicated. Because women tend to be shorter and lighter than men, bikes designed specifically for women often feature a shorter stack and reach length, for a more comfortable riding position. Many women find a better fit with unisex or men’s bikes, though - it all depends on an individual’s build.
Q: Is a suspension or rigid fork better for children?
A: As a rule, suspension forks are the better option.
Unlike rigid forks, they’re built to travel up and down a few inches as the bike rolls along, better absorbing shocks from the terrain, hence protecting your child’s body. Suspension forks also increase control over rough terrain.
That being said, rigid forks do have their advantages - without moving parts, they’re more reliable, lighter, and easier to replace.
Q: Should I put training wheels on a kids mountain bike?
A: No - it’s not a good idea to fit a mountain bike with training wheels.
A young cyclist should be able to balance and steer without training wheels before they move on to a mountain bike. This is because the new bike comes with its own challenges - such as gear changes - and is a little too advanced for children who haven’t yet got the knack of riding with only two wheels.
Our Top Pick
For us, the best kids MTB has to be this sturdy, versatile, and great value option by Mongoose. The well-known manufacturer have channeled all their usual care into this bike, fitting it with tough and lightweight alloy wheels, a powerful braking system, and 21 gears.

With its steel fork suspension, the bike is just as at home on the trails as it is on the road. All this adds up to a smooth ride, supporting your kid on those trickier hikes. With its distinctive design, excellent quality, and budget-friendly price point, this bike is the perfect starter option for any kid who wants to hit the trails.
