Cut to the chase.

Forget everything you think you know about what a 20" can do. Every aspect of this Hellion is designed in the pursuit of performance. From there, anything is possible.

At its core, is a chassis intent on handling the hardest and the biggest, by being robust but lightweight, stable but nimble. It's long, low and slack but short stayed. It has triple butted tubes and a CNC'd chainstay yoke. It's internally routed and dropper ready. It has lightweight long travel forks, air sprung naturally, and through axles front and rear.

And it rolls on the best wheel set you could hope to find on a kids bike, driven by the best drive train, controlled by the best finishing kit and held in check by the very best brakes.

It reads like a Christmas wish list: straight pull CNC'd hubs, tubeless ready double walled rims, folding tyres (upto 2.6"), four bearing cassette, low Q factor direct mount cranks, narrow wide chainring, 11-36T cassette, external cup bottom bracket, custom 35mm stem, butted riser 560mm riser bar, lock-on grips and the sweetest hydraulic brakes to bring everything nicely to a conclusion.

ASSEMBLY INSTRUCTIONS:

Your bike will arrive carefully packaged and boxed with the rear wheel attached. The front wheel will need attaching using the skewer supplied. The handlebar will be ziptied to the top tube, simply remove the bars and all packaging and attach to the stem. Add the saddle and adjust to the required height. Then simply add the pedals. Please retain your manual.
