If you're looking for something a bit cheaper, then choosing a decent, lightweight 24" wheel hybrid bike is a better bet than spending on a cheap mountain bike that is incredibly heavy and has suspension forks that don't work.

The best kids 24" wheel mountain bikes

As you will probably be aware, there is a shortage of kids bikes at the moment so this article contains some bikes that we have found in stock that might not be 'full blown' mountain bikes but are certainly capable of riding off-road trails and tracks. Please note, retailers stock levels are changing constantly - a handful of bikes may come into stock but demand is extremely high so they won't be around for long.

The Orbea MX24 XC is an entry-level kids mountain bike that is a good choice if your Cycle Sprog is just taking to the trails and wants suspension and easy to use gearing, without the cost of some of the more expensively specified models in their MX junior range.

This does mean coil suspension and V-brakes, but for most kids starting out gently this should be more than adequate. If they really take to MTBing, then you can save your pennies for upgraded features on the next size up!

What they will appreciate is the lightweight frame and single chainring (which makes changing gear so much easier than a bike with about 21 speeds).   It's these important features that separate this type of bike from some of the cheaper options you'll find being touted as "mountain bikes" elsewhere.

Forme Kinder MX24

Forme Kinder MX24

The Forme Kinder MX24 is a versatile all-rounder of a bike that will be just as happy riding some trails at the weekends as it will be doing the daily school run. 

It’s light weight is really important as your child is likely to get more adventurous with their cycling at this age, and as they ride further they’re going to have to deal with more steps, kerbs and other obstacles.

The Forme Kinder MX24 can be leased from the Bike Club - you pay a monthly subscription and when your Cycle Sprog grows out of the bike just send it back and upgrade to a bigger bike.

BTwin Rockrider 920 24 inch wheel

B'Twin Rockrider ST920

Key data:

Height range: 135-150cm
Brakes: Tektro Hydraulic Disc with 160mm rotors front and rear
Suspension:  Front:  SR Suntour XCR air suspension fork with lockout
Gears: 36T x 11-36T, 9 Speed with Shimano Altus rear derailleur and trigger shifter
Frame: Aluminium
Tyres: skinwall
Available colours: KHAKI / Fluo lime yellow

The B'Twin brand is a bicycle range from Decathlon who, incidentally, happen to be the largest sporting goods retailer in the world with a presence in 57 countries. On the cycling front, the adult range of equipment and bikes has really stepped up with some excellent products and this has started to trickle down to the junior sizes.

The Rockrider ST920 is a great entry into the world of mountain biking for junior riders. Its specification includes a Shimano Altus rear derailleur and thumb shifter for changing through the 9 speeds. It comes fitted with an 11-36 cassette paired with a 36 tooth chainset, which if I'm honest could be a few teeth smaller to make things a little easier when tackling really steep climbs. We should also point out that the Rockrider ST920 features equipment such as an air suspension front fork and hydraulic disc brakes normally seen on much more expensive bikes.

What age child is a 24" wheel mountain bike for?

Obviously, all children are different, but on average a 24" bike is suitable for children aged between about 8 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" 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.

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
