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. 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.
FEATURES:
Race Optimized Full Suspension Aluminum Frame: Built for performance, the Hellion X20 features a triple-butted dual suspension mono link frameset with a CNC'd chainstay yoke precision engineered to take big hits like a pro. 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 & Slack: The Hellion 20 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).
Full Gas Chainset: The crankset and single ring set-up give the Hellion X20 a powerful mix of performance, safety and pedalling efficiency that you just won’t see on other bikes this size. 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 Richey 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. Ritchey Logic have been at the forefront of component design for the past 50 years. We’ve collaborated with them for over a decade, producing some of best age specific components to ever grace a kids’ bike.
Big Kid Fork, Little Kid Bike: The Hellion X20 comes equipped with 100mm of smash proof front suspension courtesy of RST Spex. Featuring the same levels of adjustability typically found on much bigger kids’ bikes, the Hellion X20 can withstand pretty much anything little rippers decide to throw at it. 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: 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 MT500s. 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.
SRAM GX Drivetrain: The SRAM GX 1x10 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 SRAM GX 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 make the rare times you do need to swap tyres a breeze.
