Best kids 24″ wheel mountain bikes ages 7 to 10 years

Mountain biking is a brilliant thing to do with your child - it's fun, it gets them outside, keeps them fit, gives them a new skill and is a chance to spend time together.  If your child is aged between about 7 and 10 years of age (depending on their height) and loves riding off-road bumpy stuff, then they will be in need of one of the best kids 24 inch mountain bikes.

In this article we'll be looking at the best 24" wheel mountain bikes in different price brackets, so there's something for all budgets and types of riding.

If you need any advice on the terminology I've used in this post we've also written an article called Buying a kids mountain bike – things you need to know.

Whilst a mountain bike helps ride over the more gnarly terrains, (and of course looks really cool) it's not always needed.  Unless you're going to be doing red trails, a decent, lightweight 24 inch hybrid bike might be a better option for your child.

A quality kids bike is always a better bet than spending on a cheap children's mountain bike that is incredibly heavy and has suspension forks that don't work.

Don't forget you'll also be needing a protective pair of kids cycling gloves and a decent kids bike helmet too so check out our guides on them.

What age child is a 24 inch mountain bike for?

Obviously, all children are different, but on average a 24" bike is suitable for children aged between about 7 and 10 years of age.

In general 24" bikes tend to be suitable for children with a minimum inside leg of approx 57cm.

Every 24 inch bike has different geometry (sizing) so we've provided the measurements provided by the manufacturer, to allow you to choose the one that fits your child. Please measure your child carefully and if possible test ride the bike if you're worried it won't fit.

How much does a 24 inch kids mountain bike cost?

If your budget is under £300, then you can get your child a decent mountain bike that will provide miles of off roading fun, but beware - there's lots of poor quality MTB's out there, which are a false economy.

You want to be buying something that will last and can be enjoyed for years to come.

Don't be fooled by full suspension bikes and loads of gears - they will make things harder rather than easier.

Once you start paying over £300 for a 24" wheel mountain bike for your child you will start to see higher lighter frames, quality components and easier to use gearing.

Top of the range specifications start about £600 and if you want you can spend thousands!

What to look out for on a kids mountain bike

  • Frame: Many frames on cheaper kids mountain bikes will be steel, which are heavier than a more expensive aluminium framed kids MTB. It’s worth remembering this if you’re going to need to lift/carry/push the bike, or plan riding somewhere very hilly.
  • Gears: The gearing on a cheap kids mountain bike tends to be 18 speed or over, meaning your child has to master using gears with both their right and left hands. This can be a bit confusing and is avoided by having a single chainring and less gears to give the same amount of assistance on the hills. It will possibly take your child longer to master more gears and there’s a bigger chance of them “crossing the chain” so they’re not using gear efficiently when climbing. If you’re aware of this, you can help them get the gears correct before you set off up a hill.
  • Braking: V-brakes should be plenty good enough to bring a bike to a halt on more gentle hills in dry conditions. More expensive mountain bikes tend to have disc brakes for better stopping in the wet/mud.
  • Suspension: Decent MTB's at the cheaper end of the range will have front coil suspension or no suspension (called a rigid fork mountain bike) – this is a much better option than some cheap mountain bikes bikes which claim to be full suspension but don't work and just add lots of weight, making it tiring to ride.
  • Tyres: The more expensive the mountain bike, the better the tyres will be for tackling wet, muddy and rocky terrain. Generally, the wider the tyre the better the grip off road, but the harder it becomes to pedal on the road. This is why we recommend a more general 24" wheel kids bike if your child will be cycling on a mix of surfaces.

Best kids 24 inch mountain bikes

The brands featured all have several 24" wheel mountain bikes in their range at different price points.

This means you should find a MTB suitable for kids aged between 7 and 10 years old, what ever your budget or the type of riding they're doing.

Price range: £199.99 - £349.99

BTwin are the in-house brand of kids bikes at Decathlon, and they come in a range of prices and specifications.

The original Rockrider ST500 24 inch is their best selling kids bike.  It's a steel framed entry level mountain bikes, suited for gentle riding on or off road.

It weighs in at 14.5kg so it rather heavy compared to the other bikes on this page - something to remember if you're lifting it onto the roof of your car.

The v-brakes should be plenty good enough for gentle off roading in fair weather, and the bike has front coil suspension to smooth out some of the bumps on the trail.

One thing to note with this model of the bike is that the gearing is 18 speed (which can be more confusing than 6 or 7 gears due to needing to use both hands to change gear).

The BTwin Rockrider offers a really good value entry level mountain bike, that should provide plenty of scope for fun during summer riding.

*** DEAL OF THE WEEK:  The original Rockrider ST500 24 inch is currently reduced down to £199.99 at the time of writing, as it is being replaced by a newer model ***

The newer version of this bike is called the BTwin Expl 500, and has the added benefit of having a single chain ring, making it much easier to ride.  With only 7 gears your child can enjoy their ride, rather than worrying about what gear they should be in.

This bike only landed with Decathlon in spring 2024 and they've told us it's "for intermediate riders and specifically designed for trails".   If you can afford the additional £50 over the reduced bike we'd recommend the Expl 500 for the better riding experience.

Finally, if you've got a bit more cash to splash then we'd highly recommend their premium model.

The BTwin Rockrider ST900 24" wheel MTB is a more generously equipped kids mountain bike with a lightweight aluminium frame design paired with a Suntour XCT suspension fork with 50mm of travel to help cushion the lumps and bumps of forays through woods and forests.

At 12.25kg the lower weight will not only make it more fun to ride, it's also easier for you to lift onto a car rack - your back will thank you!

At the other end of the market from the B'Twin bikes sit woom - an company dedicated solely to making the best kids bikes.

Here at Cycle Spog we've reviewed many of their bikes over the years and have never been disappointed.  We currently have a woom OFF out with a reviewer who is raving about it!

The woom OFF 5 is the rigid fork offering and weighs in at just 8.6kg due to its specification comprising an aluminium frame matched with a quality carbon fork.

The nine speed gearing is provided by SRAM X5 shifters and rear derailleur, with an 11-34T cassette matched to a 28t chainset designed for kids so the crank arms are of an appropriate length.

The woom OFF 5 is fitted with Promax hydraulic discs that feature 140mm diameter disc rotors front and rear.

The woom OFF AIR 5 is essentially the same bike with an air suspension fork providing 80mm of travel plus adjustable compression and rebound damping with lockout.  This increases the weight to 10.1kg.

Orbea have two kids MTB models - the cheaper MX range and the premium Laufey.

However, there's lots of different specifications within Orbea's 24 inch mountain bike range. So how do you know which to buy?  We'll try and explain!

The Orbea MX Dirt 24 is their entry level 24" wheel mountain bike. It has an aluminium frame with a high tensile fork, v-brakes, 7 gears (14-34T) and Kenda 2.2" wide tyres.

This is a good option if your child is doing leisure riding at the weekend on a mix of roads and paths with some mountain bike trails thrown in.

The Park 24 is the same bike with a kickstand, mudguards, more road friendly reflective tyres and lights making it a better option if your child commutes to school but also leisure rides at the weekend.

The Orbea MX 24 XC is the same bike as the Dirt but with a 50mm front coil suspension fork making it more suited for kids who's primary focus is mountain biking (or who just desperately want a "proper" mountain bike with suspension).

The Orbea MX Team 24 has a lighter weight aluminium rigid fork, and different gearing (11-36T 9-speed) which will be of interest to you if you're planning on taking your child up some steep hills or they need a lighter weight bike for racing.

If your child is seriously getting into mountain biking the Orbea Laufey range takes things up a notch or two with Shimano MT410 disc brakes and Sun Race 11-42T 10-speed cassette.

The Orbea Laufey H30 is the entry model which is specified with a rigid aluminium fork.

The H20 adds a 80mm air fork, dropper seat post and Schwalbe Rocket Ron Foldable tyres.

For ultimate off roading fun, the top model in Orbea's extensive 24" wheel kids mountain bike range is the Laufey H10, which comes with 100mm air fork and an upgraded headset.

Price range: £369 - £1,049

You should consider the Norco Storm 4.1 – brilliant value and very vibrant!

David purchasing 24inch bike as a frame only is probably going to be a challenge .

Momsen South Africa does have an Australian dealer network so it might be viable purchasing a complete bike (JSL 40) as its decent and cheap enough.


Can you recommend where I can buy a good quality hard tail MTB frame for 24″ wheels? I would want it shipped to Australia.


David – I recommend you contact bike retailers directly to see their current shipping policies – I know many are no longer shipping internationally at the current time. Kind regards, Karen

Was the Early Rider Trail 24 no good? We’re on the Belter Trail 16 which has been great.


Hi Ruth – thanks for getting in touch. Sadly, we’ve not been able to review any Early Rider bikes. The Trail 24 is not available at the moment, so we’ve not included it. Karen


Momsen JSL40 might be worth a look.

Thoughts on the Ghost Kato 24″?

Bob Ridgway

Shame that the manufacturer’s don’t sell the frames as I usually build up my son and daughters bikes and have been using second hand Giant XTC 20 and 24’s which I have stripped and powder coated to their colour choice Daughters pink and then lime green, with sons bright orange. Next 24 for son will be nearly shortly so in the market for another 24 MTB


It’s a pity isn’t it. Sounds like your Cycle Sprogs have some great unique bespoke bikes (and no doubt keeping you busy each time they grow!) Karen


Surprised no mention of the Canyon range. Their bikes are normally very good and well priced. Are they no good?


Not sure if you can get them in the UK, but the Diamondback Sync’r 24 beats – arguably – all bikes you mentioned in this article. It’s a better bike – just not sure the UK price, and thus the “value.” SRAM NX 11-speed, hydraulic brakes, air fork, sub 27 pounds. Yes, Diamondback was making yucky bikes for a long time, but it looks like they are getting back to their roots. Sweet ride. I suspect many other mfgrs will have to try to catch up. No one else is close. (Drawbacks: 720mm bars might be a bit wide; 165mm NX cranks a bit long when 155mm are available.)


Hi Frank – sadly the Sync’r isn’t available in the UK at the moment. Good to hear Diamondback getting back to their origins – will definately keep an eye out for this bike. Karen
