Adventure made easier.

Meet the Hellion X24

The Hellion X24 features a triple-butted aluminium full-suspension frame with a CNC’d chainstay yoke, 100mm DNM rear shock with adjustability taking it up to 125mm, and 120mm front suspension for smooth, controlled trail feedback. Its long, low, and slack geometry ensures stability, confidence, and playful handling. Narrow-wide chainring, forged cranks, and SDG junior touchpoints enhance performance and control. With RST F1rst forks offering adjustable air, compression, and rebound, it's built for progression and tough trails.

Closer look

The full story

A race optimised full suspension aluminium frame

Built for performance, the Hellion X24 features a triple-butted dual suspension mono link frameset frameset with a CNC'd chainstay yoke that’s precision engineered to take big hits like a pro.

The 100mm DNM rear shock pairs brilliantly with the 120mm up front to deliver exceptional trail feedback, smoothing out roots, rocks and big drops. The frame tubing has been deliberately crafted to balance strength (at the pressure points) with lightness, ensuring we don’t waste valuable grams where we don’t need it.

Threaded thru axles ramp up frame stiffness while sliding dropouts give them handling and size adjustments as they progress. To top it off, we added internal routing for a stealth dropper because progression is everything.

Long, low and slack

That’s the assignment and we understood it.

The Hellion X24 is built for performance with a geometry optimised for speed, technical acumen and confidence on the gnarly bits.

The low centre of gravity keeps them balanced in the berms while the slack head tube angle takes (some of the drama) out of descending. The short seat stays give the bike a playful responsive feel (while also making manuals just a little easier to master).

A no fuss, full gas chainset

Built for performance, the Hellion X24 features a triple-butted dual suspension mono link frameset frameset with a CNC'd chainstay yoke that’s precision engineered to take big hits like a pro.

The frame tubing has been deliberately crafted to balance strength (at the pressure points) with lightness, ensuring we don’t waste valuable grams where we don’t need it.

Threaded thru axles ramp up frame stiffness while sliding dropouts give them handling and size adjustments as they progress. To top it off, we added internal routing for a stealth dropper because progression is everything.

Anatomically designed cockpit

The Ritchey Jr cockpit is anatomically designed for progression and control. When everything fits right, steering becomes more precise, more controlled. The lock on grips prevent hand slip in the inevitable wet muddy conditions.

The X24 also comes spec’d SDG fly junior saddle and SDG Slater pedals which not only offer stability and performance on tougher trails, but also look seriously cool.

Big kid forks for big hitters

The 120mm RST F1rst forks with 15mm thru axle come with the same levels of adjustability you’d expect from a far bigger bike without losing any of the responsiveness lightweight riders need.

Make fine adjustments to air suspension, compression and rebound to dial in their ride, and accommodate growing bodies.

Lightweight, adjustable brakes

Featuring a lightweight, smooth modulation, plenty of adjustability and ultra reliable braking, it’s no wonder we’re such big fans of Shimano’s Deore MT600s.

Braking feedback is predictable with a smooth modulation that prevents unnecessary emergency stops while the 160mm 6 bolt rotors give bold riders the confidence they need to go hard, and stop harder.

A Shimano Deore drivetrain

The Shimano Shimano Deore 1x11 is a robust, efficient, and versatile drivetrain that balances simplicity with performance. The low-maintenance setup which saves valuable weight without sacrificing performance. With its smooth, accurate shifting, superior weight and robust build, there’s a reason why Shimano Deore is the drivetrain of choice for so many pros.

MTB wheels that go hard

Fully sealed bearing hubs, tubeless compatible, double wall rims and optimised spoke count means these wheels rip.

Because there’s no point speccing a great bike with weak wheels.

Sealed bearings keep mud, water and corrosion at bay while double wall rims give you twice the confidence on rocks and roots.

The optimised spoke count means you won’t have to worry about buckled wheels while thru axles makes the rare times you do need to swap tyres a breeze.

Everything we’ve come to expect and then some.

This is our third Early Rider going all the way back to our daughter’s 1st pedal bike at 3 years old. Her progression, confidence and love for biking all came from having gear that was high quality and lightweight that she could grow into.

Fast forward to today and she’s 7 years old (tall for her age) and sending it on a bike and on terrain that I didn’t progress to until I was an adult. I can’t overstate the quality of the Hellion X line- these are absolutely the kid sized versions of the coolest $8k downhill bike a parent can ride. Excellent quality on the frame and great choices made on all components- each customizable and ready to tune as she grows and changes her riding style. Ready for anything she’ ll be able to throw at it.

The price point is more than fair for what you get and it’s really an investment in the rider you’re trying to develop. There’s a difference between price and value- and the value here is unquestionable.

I can’t say enough about these bikes- they have been fundamental in creating my shredder and I’m very grateful to Early Rider for making something like this available in the market. These bikes fuel the stoke of our entire family to get out and ride!

Perfect Bike

This bike was bought for my daughter, she had another brand 24" full sus bike but just couldn't get on with it. She had come off a 24" hellion hardtail and a 20" hellion before that. I should have stuck with what we already knew. Early Rider make amazing children's bikes that are fit for the purpose and can handle anything a full size bike can. We have been so impressed with the bikes we've had. And their customer service has been second to none. I cross threaded a bolt being heavy handed, they sent out a replacement the same day for free. I had an issue with the forks, again it was me, they just needed more air in them, the mechanic team talked me through it without making me feel the plonker I am!

The only negative is that you don't make a bigger size!

Thanks Everyone at Early Rider

Excellent

Everything was excellent and my son is super happy! The only issue I had was after setting up the wheels and tires tubeless the Vee tan wall tires would not hold air and leaked out of the sidewall badly. I swapped On some Maxxis rubber and they sealed perfectly.
