The best full suspension kids mountain bikes

With full suspension becoming more popular on adult mountain bikes, it’s not surprising that there is a growing demand for kids sized full suspension MTB’s.  In this article, we’re taking a look at some of the best full suspension kids mountain bikes with 26″ wheels or bigger that are currently available for older kids and teens (about aged 10 plus) at the moment. As you’ll quickly see, they don’t come cheap – but in each case, you’re getting a lot of bike for your money.

Does my child need a full-suspension mountain bike?  

Now, some will argue that your Cycle Sprog should be learning their skills on a fully rigid or hardtail mountain bike before moving onto the comparative luxury of full suspension later in life (when the bones start creaking and muscles need warming up before a ride!).  Others will retort that if it means their Cycle Sprog can get up and down whatever the trail throws at them, then it’s a great thing, and means your family mountain biking can reach exciting new levels (assuming you can keep up!).

The best full suspension kids mountain bikes 

Before we start – let’s just ask why a pre-teen or teenager shouldn’t just jump on an adult mountain bike.  Yes, it’s possible to get an XS or S adult MTB, but often they’re not designed with kids in mind. Those aged between about 10 and 14 tend to have smaller hands, narrower shoulders, and aren’t as strong as adults, so need a bike designed specifically for them.  Here’s our pick of those full suspension kids mountain bikes designed with the junior rider firmly in mind.

COVID-19 / CHRISTMAS UPDATE - November 2020

There was a huge rush on the sale of kids bikes when the spring lockdown started and as a result there is now a shortage of new kids bikes across the UK. We predict that is going to get even worse as Christmas gets nearer, so it's wise to get sorted early this year. 

If you need a new bike urgently (e.g. for a birthday present) then check out this post Help! Where can I buy a kids bike with quick delivery?

We've kept all our links to new bikes in place in this article, so you can check retailers availability of stock, but we've also added in links for you to look for bikes secondhand (in green).   All the bikes we list are quality bikes built to high standards and make great secondhand buys. 

It's also worth checking out The Bike Club to see if they have any bikes left to lease in the size / brand you want. You pay a monthly subscription and then upgrade to the next size when your child outgrows it. You can cancel at any time. Plus you get a warm glow from helping the environment, as well as avoiding the upfront cost of buying outright.

Mondraker Factor 24 (rrp £2099)

Mondraker Factor 24 mountain bike

Mondraker Factor 24 key data:

Price: £2099
Typical age range
: 8-11 years;
Height range:
135-155cm;
Brakes
: Shimano MT-501 160mm;
Frame
: Factor 26” Stealth 2.0 Zero Suspension System 90mm;
Tyres
: Kenda Small Block Eight 24×2.1;
Warranty: Please check with supplier

Mondraker is based in Alicante, Spain and has been making full on mountain ‘bicicletas’ since 2001. They produce the Factor 24 and 26 and take everything they’ve learned and boiled it down to a size suitable for pre-teens and teenagers.

The Factor 24 is not a downhill monster of a bike but is set up with a more XC bias having a RockShox Monarch R shock at the rear and a RockShox Gold RL Solo Air fork giving 80mm of travel.

The specification for the Factor 24 shows that Mondraker have fitted Shimano’s MT501 4 piston brakeset to the bike, which should give supreme braking power.

There’s also a tasty drivetrain too for this updated 2020 model, with a SRAM Eagle 12 speed groupset being used for the crank, shift lever, and rear mech, with a massive 11-50T cassette out back. We’ve had good experiences with SRAM groupsets, so it’s reassuring to see the Eagle being used here.

It’s also interesting to note that Mondraker has made use of branded high-quality components throughout, such as the OneOff bars and stem and saddle from SDG, rather than using in-house products. But then again, when you’re paying a significant sum of money you do, quite rightly, expect more than a smattering of top kit for your investment.

Hailing from British Columbia in Canada, the guys at Norco certainly have the right environment in which to build bikes for jumping on and exploring the great outdoors. Based around the 2020 adult Sight, the Youth version is scaled down to ensure it fits correctly with a fantastic specification to boot.

Fitted with a Rock Shox Pike fork giving 150mm of travel at the front and a Rock Shox Deluxe R shock providing 140mm of travel at the rear, Norco has tuned both to take account of lighter riders.

This is a bike designed for all-mountain riding and everything such tough trails can throw at you. There’s a dropper post already fitted and the drivetrain is SRAM’s 12 speed Eagle setup, complete with massive 11-50 tooth cassette. There can be no excuses!

Hotfooting it out of British Columbia is the Norco Fluid 24 FS that is a full suspension kids bike for ages 8 and up. It’s fitted with a Manitou J-Unit air fork to give 145mm of travel at the front and complemented by an X-Fusion shock supplying 120mm at the rear.

There’s a decent 11-speed drivetrain using SRAM’s excellent NX range for the shifter and rear derailleur, while a SRAM SX 30 tooth 1X chainset has been specified to match up with the SRAM 11-42 cassette.

Braking comes courtesy of a Shimano hydraulic system. Short reach levers are the order of the day, with 180mm rotor at the front and 160mm at the rear. Stopping shouldn’t be an issue!

Whyte T-120 26″ wheel (RRP £1599)

Whyte T-120 youth full suspension mountain bike

Whyte T-120 key data:

Price: £1599
Height range:
135-150cm;
Brakes
: Tektro Orion, 4 Pot, 180mm Rotor;
Frame
: 6061 T6 SCR Aluminium Front Triangle with Tapered Head Tube and Intergrip Seat Clamp System, Alloy Symmetrical SCR Rear Triangle, 148mm Boost Dropouts;
Tyres
: WTB Trail Boss, Light/Fast TCS System 26” X 2.25”, 60TPI;
Available colours
: Matt petrol/mist;
Warranty
: Frame: 2 years - can be extended to 4 years if registered within 28 days of purchase. Doesn't cover racing, jumping or tricks

Whyte has invested heavily in the kids and youth market, giving parents credible alternatives at existing wheel sizes but also looking for gaps in the market where models for kids don’t really exist. From past experience, they certainly create top quality bikes that fulfill the needs of riders, and the T-120 looks to be no exception. They also build their bikes for use in UK conditions too, which is no bad thing.

Based on the T-130 frame, an award-winning full suspension enduro machine, the T-120 comes as a 13″ frame fitted with 26″ wheels as Whyte believe that provides a better balance than fitting 650b (27.5″) wheels. Size-wise, the Whyte website gives a recommended rider height for the T-120 of between 135 – 150cm.

As you would imagine, the spec is pretty high with a 10-speed gear set up using Shimano’s very well respected Deore range for both the shifter and rear mech. The chainset is a Whyte own brand with 28 teeth and suitably sized crank arms of 165mm. The rear cassette comes from SunRace and has a broad spread of 11-46 teeth over its ten sprockets. Braking should also be on the button with Tektro Orion 4 pot calipers clamping down on 180mm rotors.

Whyte has set a recommended retail price of £1599 for the T-120.

Price: £1699
Bike weight: 13.9kg;

Frame: HPA Ultralight, Advanced Hydroform, Triple Butted, ETC 4-Link, ISCG Mount;
Tyres: Schwalbe Hans Dampf, APerfL, 2.35;

Cube are no strangers to the world of full-suspension, producing a broad selection of top quality mountain bikes for the adult market. Of course, they didn’t stop at that because kids should get to enjoy the delights of a full-susser too, so a couple of years ago Cube brought out the Stereo 140 Youth – an awesome bike that we were lucky enough to test.

For 2020 Cube has once again created a 27.5″ wheel full suspension bike for kids based upon the cutting edge technologies they employ in the adult range. This is based around a custom-sized triple-butted lightweight alloy frameset that comes in two sizes – 13.5″ and 16″.

With 120mm of travel provided by the SR Suntour XCR34 air fork and SR Suntour Edge R shock, there’s plenty of fun to be had.

Cube has specified SRAM for the transmission with an Eagle 12 speed setup throughout, featuring 30 tooth chainset and seriously wide range 11-50t cassette to give amazing gear options to cover all eventualities. Braking comes courtesy of Magura MT Thirty with 180mm rotors front and rear, so retardation of speed should not pose a problem.

The Cube Stereo 120 Youth certainly looks amazing and with such a quality specification we’re expecting junior riders will be enthused to get out, ride and grin from ear to ear.

Marin Hawk Hill Jr MTB (rrp £1445)

 

Marin Hawk Hill Jr kids full suspension bike in blue and black

Marin Hawk Hill Jr Key data:

Price: £1,145
Typical age range: 7-10 years;
Height range: 125-165 cm;
Brakes: Shimano MT-201 Hydraulic Disc;
Frame: Series 3 6061 Aluminum Frame;
Tyres: Vee Tire Co;
Available colours: Cyan/black;
Warranty: Check with retailer if outside USA (in USA it’s 5 yrs on frame)

Before you baulk at the thought of paying over 1,300 notes for a kids mountain bike, take a look at the large clearances on this bike, and the fact that it’s got rear suspension. Yes, the Marin Hawk Hill JR is a top of the range kids 24″ wheel full sus MTB, that is also able to take 26″ wheels. So you’re effectively getting two full suspension mountain bikes for the price of one (albeit you do need to get your hands on a set of 26″ wheels – reasonably cheap these days!)

The Marin Hawk Hill is a 120mm travel rig, using X-Fusions excellent Velvet fork with thru-axle and their O2 Pro shock at the rear which, being air, allows for precise tuning to take account of varying weights at the age range the bike is intended for. The frame on the Hawk Hill Jr is lightweight T6061 aluminium with internal routing for the rear mech and also for a dropper post should you wish to fit one.

The Marin Hawk Hill JR is based around the best selling adult bike of the same name, just with scaled down components for a younger rider.  With an 11-Speed SunRace 11-46T cassette this bike will get up most hills without a problem, and the air-sprung front X-Fusion Velvet RLC 26″ front suspension gives 120mm of cushioning travel when making your way back down.

All in all a great looking bike with the added functionality of being able to grow with your child.

In terms of the upgrade to 26″ wheels we have confirmed with Marin that they need to have the following axle spec:
Front Wheel – 100 x 15 thru-axle
Rear Wheel – 135mm open dropout that can be upgraded to 142 x 12 thru-axle if required

Cube bikes have a broad range of bikes, such that pretty much there’s something for everybody, regardless of age or type of riding.

    We bought my son a commencal supreme 24” which has now moved on to a new owner.
    I couldn’t recommend this bike enough – we rode at quite a few bike parks and it coped with all grades of runs.
    A great kids full suspension bike worthy of a 9/10 and delivery from the factory to your door.😊
