Adventure made easier.

Meet the Hellion 16

Featuring a 6.8kg triple-butted aluminium frame, 140mm disc brakes and a tough rear end, the Hellion 16 is the perfect combo of tough and light, perfect for fearless 4-6 year olds. Threaded thru axles boost stiffness, while sliding dropouts and internal cable routing ensure versatility and sleekness. Low, slack geometry provides stability and confidence, while narrow-wide chainring and 110mm cranks enhance pedalling efficiency without the chain slap. Tubeless-compatible wheels with sealed hubs tackle tough trails, and hydraulic brakes with eco-friendly mineral oil ensure safe, reliable stopping for little shredders.

Closer look

The full story

A performance optimised aluminium frame

Built for performance, the Hellion 16 features a triple-butted aluminium frameset with a CNC'd chainstay yoke that’s precision engineered to take big hits like a champ.
The frame tubing has been deliberately crafted to balance strength (at the pressure points) with lightness (everywhere else), to ensure we don’t add unnecessary weight or hinder progress.
Threaded thru axles ramp up frame stiffness while sliding dropouts enable handing and size adjustments as little riders progress.
To top it off, we added internal cable routing because a bike this slick demands it.

A low, slack and short geometry

That’s the assignment and we understood it.

The Hellion 16 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

Touchpoints that elevate control

Every one of The Helion 16’s competition level touchpoints are built to save weight without compromising on performance.

We’ve collaborated with the brilliant Ritchey Logic to deliver a perfect rail adjusted ergonomic saddle, combined with robust seat post and quick release clamp. The double butted aluminium bars are strong, light and small enough for mini rippers to keep control.

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 the best age specific components to ever grace a kids’ bike.

Gear ready and engineered for fast progression

The Helion 16 is designed for rider and bike progression. As they improve, you’ll find their need for a few gears increases.

We supply the Helion 16 gear-ready, with a separate mech hanger, gear routing and rear hub which allows the addition of a small ratio cassette.

This allows them to learn the fundamentals of gear shifting in a bike they’re comfortable with. And it allows you to eek out way more value from a bike that’s already designed to last a lifetime.

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.

The 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.

Tan walls for the win

Big adventure requires big tyres and we’re not playing around when it comes to speccing the Helion.

Whether you’re navigating mud, berms, ruts or roots, our 2.25" knobbly tyres deliver traction, control and protection.

And everyone knows that tan wall tyres just look better.

Light, powerful hydraulic disc brakes

At 65g, the 140mm hydraulic powered disc rotors mean business. Because sending it relies on stopping it. With partially rounded edges and 6 bolts you’re also guaranteed extra safety even when you’ve stopped.

The brake levers features a lightweight, and most importantly, adjustable action to accommodate small hands.

We also made the decision to replace the brake fluid with mineral oil. It’s less corrosive and a bit kinder on the environment.

Best 16 inch bike

Excellent. Only kids bike I've seen that is built like a proper bike. Brakes are awesome but might need a new rear tyre soon!

Great Early Rider Experience

We were really happy and proud to see our 3.5 y-o child to roll off right away on his new bike. His Hellion 16 is of great quality and is already adding unforgettable memories to the whole family. The team based in Oxon RG9 4LG was very friendly and helpful. We definitely recommend.

Amazing Bike!

Could not ask for better quality in a kids bike, it’s anxiously amazing. The geometry fits my 4yr old perfectly and it’s super light. Very impressed!

Amazed by the Hellion 16!

The bike is brilliant!

James is a touch too small based on the dimensions given but he rides this bike so much better than his seeker 14. The bike geometry is perfect for children’s body shape and size, allowing him to pedal comfortably, reach the brakes and control the bike.

The brakes have great stopping power, a big upgrade from the v brakes on the seeker 14.

We have had the bike 2 weeks and James’ riding has come on so much in that time frame!
