Meet the Hellion X20

A full-suspension 20" MTB built for young riders who want to send it. Its long, low, slack triple-butted aluminium frame, 95 mm rear shock and 100 mm adjustable RST Spex fork soak up rough trails while keeping things fast, stable and agile. A narrow-wide chainring with forged cranks and SRAM GX 1x10 drivetrain maximise pedalling efficiency, and Shimano Deore brakes plus tubeless-ready wheels with 2.25" Vee Crown Gem tyres deliver confident grip and stopping power when the trail gets serious.

A race-optimised full-suspension aluminium frame

The Hellion X20’s triple-butted mono-link frame with CNC’d chainstay yoke is built to take big hits while staying light and fast. With 95 mm DNM rear travel perfectly matched to 100 mm up front, it smooths out roots, rocks and drops, while thru-axles and sliding dropouts add stiffness and let you tweak fit and handling as they progress. It’s even dropper-ready, because progression is everything.

Make it stand outLong, low and slack

The Hellion X20’s geometry is tuned for speed, confidence and control when trails get gnarly. A low centre of gravity keeps them planted in berms, a slack head angle calms steep descents, and short seat stays give a playful, responsive feel that makes flicking the bike around and learning manuals that bit easier.

A no-fuss, full-gas chainset

The Hellion X20’s single-ring setup and forged direct-mount cranks deliver serious power, safety and efficiency for its size. A narrow-wide chainring keeps the chain locked in place, so every pedal stroke drives them forward with maximum confidence.

Anatomically designed cockpit

the Hellion X20’s Ritchey Jr bar and stem are sized for young riders, making steering precise and controlled, with lock-on grips that won’t slip in wet, muddy conditions. An SDG Fly Jr saddle and SDG Slater pedals add stability and performance on tougher trails – and look seriously cool doing it.

Big kid forks, little kid bike

The Hellion X20 runs 100 mm of tough RST Spex front suspension with the kind of adjustability you’d expect on a much bigger bike. With tunable air, compression and rebound, you can dial in the fork to their weight, terrain and skill level so it’s always ready for whatever they throw at it.

Lightweight, adjustable brakes

Shimano Deore MT500s deliver smooth, predictable modulation and plenty of tuning for growing hands, so stopping feels controlled, not jerky. With 160 mm rotors, bold young riders get the confidence to go hard, knowing they can stop even harder when it counts.

A SRAM GX drivetrain

the GX 1x10 setup is robust, efficient and low-maintenance, saving weight without sacrificing performance. With smooth, accurate shifting and a tough, lightweight build, it’s the kind of drivetrain pros trust and kids can rely on ride after ride

MTB wheels that go hard

Fully sealed hubs, tubeless-ready double-wall rims and an optimised spoke count mean these wheels are built to rip, not buckle. Sealed bearings shrug off mud and water, while thru-axles add stiffness and make the rare tyre change quick and easy.
