Early Rider Hellion X20
A 20” full suspension trail bike that’s happy on dirt jumps, single track and the junior circuit. Built for 6-8 year olds with a spec coveted by much, much bigger kids. The Hellion X20 doesn’t need to go this hard.
Meet the Hellion X20
The Hellion X20 is a full-suspension MTB with a triple-butted mono-link aluminium frame and CNC'd chainstay yoke optimised for strength without unnecessary weight. The 95mm DNM rear shock pairs nicely with 100mm up front thanks to the fully adjustable RST Spex forks to smooth out the worst of the trail. Its long, low, and slack geometry ensures confidence, speed, and agility, while a narrow-wide chainring, forged cranks, and SRAM GX 1x10 drivetrain boost pedalling efficiency and chain safety. Shimano Deore MT500 brakes and tubeless-ready wheels with 2.25" Crown Rubber Vee Gem tyres deliver reliable stopping and rugged performance.
A race optimised full suspension aluminium frame
The 95mm DNM rear shock pairs brilliantly with the 100mm up front to deliver exceptional trail feedback, smoothing out roots, rocks and drops. The frame tubing has been deliberately crafted to balance strength (at the pressure points) with lightness, ensuring we don’t waste valuable grams and they don’t lose valuable seconds.
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 a cable guide for an external dropper because progression is everything.

Long, low and slack
The Hellion X20 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
The narrow wide chain ring stops the chain from flapping while working in harmony with the forged aluminium direct mount cranks for maximum power transfer when it matters.

Anatomically designed cockpit
The X20 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, little kid bike
Fine tune the float with adjustable air suspension, compression and rebound to dial in their ride according to the demands of their skill set, terrain or current weight.

Lightweight, adjustable brakes
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 SRAM GX drivetrain

MTB wheels that go hard
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.
