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 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.

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.

Good.

The good: awesome suspension design, excellent components, good value. Fast shipping. Never heard of the DNM shock but it seems to work ok. Great deal for the “factory second” that had absolutely nothing wrong with it.

The not so good:

1. No way this is 25.5 lbs as claimed. 28.0 on my scale. That extra 2.5 lbs is a big deal for a little kid if they plan to pedal at all.

2. No bottle cage

3. Vee tires feel pretty cheap - they feel like plastic and are difficult to setup tubeless.

4. Raw aluminum looks cool, but feels kind of like a cut corner. The painted version wasn’t available.

What would I change/upgrade? Stan’s wheels and better tires (Schwalbe or Maxxis).

Would I buy it again? Honestly at 28lbs, probably not given what else is available in the price range. But, it’s still an awesome bike and my son loves it so we’ll call it a win.

Awesome

What a brilliant bike. I bought through early rider site as a factory second at a reduced price, still trying to find anything wrong with it!

The bike arrived within 3 days by courier, great service. Here's some stats for prospective buyers. Bought for my 10 year old son who is 130cm tall. The only bit of extra setting up I did is cut 3 inches off the seat tube now it is perfect height without hitting the rubber grommet on the seat stay, which I presume is for an aftermarket dropper post?

We will be hitting the pump track and woods this weekend but I can only expect it to be great.

Die Referenz für junge Trailbiker

Unser Sohn liebt dieses Rad - und ich auch. Leicht, in der Enduro-Einstellung absolut trailgeeignet mit ausreichend Federweg war auch Finale kein Problem. Mit dem 10- jährigen Buben den Roller Coaster fahren ist schon was besonderes für mich.

Die Geometrie ist für Kids perfekt, die Komponenten hochwertig und zuverlässig. Lediglich die Federgabel hat Verbesserungspotential.

Trotzdem: absolute Empfehlung für Kids, die auf Trails und im Bikepark richtig Spaß haben wollen.

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.

Not as Marketed!

I bought the Early Rider Hellion X24 thinking it would be a lightweight and great bike for Downhill, Trail, and XC (like marketed). This bike is not that. First off, they market this as a "gravity bike" (downhill bike), but the suspension fork (which is a major component) specifically says “Do not use for downhill, freeride, or jumping” ON THE FORK. A bike marketed for these things should not have a warning sticker on the fork that says not to do those things with the bike. The fork also feels terrible, it's sticky and harsh going over anything. The rear shock also does not have enough travel for any "real" bike park riding (like marketed). It will get you through the greens and blues just fine, but for anything more I would look elsewhere. (I have done an 8 foot drop on it and it held fine, but it was not safe.) The user manual claims the bike is not intended for anything above a blue, and not to do drops over 2 feet. The website says nothing of this. I would strongly advise you to look at other brands with much better advanced kids bikes like Norco, Commencal, Vpace, Cube, Transition, even Rocky Mountain. We also contacted Early Rider for different reasons multiple times and got no response.
