The best full suspension kids mountain bikes - 2019

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 avaialble 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 hard tail 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 adults 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.

Cycle Sprog reviewed and recommended

Cube bikes have a broad range of bikes, such that pretty much there's something for everybody, regardless of age or type of riding. They've recently added to their collection the Cube Stereo 140 Youth - a full suspension 27.5" wheel bike that comes in three different frame sizes to cater for most pre-teens and teenagers.

Cube Stereo Youth 140

The Cube Stereo 140 Youth is a proper off road tool with SR Suntour Aion forks that give 150mm of travel at the front, while suspension duties at the rear are provided by an SR Suntour DUAir shock giving 140mm of travel. There's a RaceFace 1x chainset with an 11 speed SRAM NX drivetrain with great gearing options. Magura provide the braking with 180mm rotors giving plenty of bite!

We've been lucky enough to have been testing one of these bikes out this year, and have been very impressed. You can read our review to see what 12 year old Tester N thought of the Cube Stereo 140 Youth here.

Braking comes courtesy of a Tektro hydraulic system with short reach levers and 160mm rotors.

The Norco Fluid FS 26 also comes ready fitted with a dropper post with remote lever.

Marin Hawk Hill Jr (RRP £1,350)


Out of stock as of 26 April 2019

Now the Hawk Hill Jr from Marin is an interesting concept as it starts out as a 24" bike that, when the time is right, can grow with your child as it accommodates 26" wheels (it's worth pointing out that Mondraker also do similar with their smaller Mondraker Factor 24).

The Marin Hawk Hill is another 120mm travel rig, but this time using X-Fusions excellent Velvet fork with thru-axle and their O2 Pro shock at the rear which, being air, allow 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.

Braking comes form the budget but very well respected Shimano M315 hydraulic system which in this guise uses a 180mm rotor at the front and a 160mm at the rear to give great stopping power for lighter riders. The 10 speed drivetrain comprises an 11-42T cassette and makes use of the Shimano Deore range for the rear mech and the shift lever, while Marin use their great in-house range for the 30 tooth crankset and finishing kit on the bike.

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       -              15x100 axle
Rear Wheel        -              12x142 axle


Mondraker Factor (RRP £1,995)

Mondraker are based in Alicante, Spain and have been making full on mountain 'bicicletas' since 2001. The Factor 24 and 26 take everything they've learnt and boiled it down to a size suitable for pre-teens and teenagers.

Mondraker Factor 26 is one of the best 26" wheel full suspension kids mountain bikes

The Factor 26 is not a downhill monster of a bike but is set up with a more XC bias having a 90mm RockShox Monarch R shock and a RockShox Gold TK Solo Air 30 air fork giving 100mm of travel.

The specification for the Factor 26 suggests 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 2019 model, with a SRAM NX 11 speed groupset being used for the crank, shift lever and rear mech. We've had good experiences with the SRAM NX groupset, so it's reassuring to see it being used here.

It's also interesting to note that Mondraker have made use of branded high quality items 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.
