Meet Hellion 24

The Helion 24 is built for performance, featuring a triple-butted aluminium frame with a CNC'd chainstay yoke, threaded thru axles for stiffness, and sliding dropouts for adaptability. Its long, low, slack geometry ensures confidence, balance, and playful handling on technical trails. Shimano Deore 1x11 delivers precise, durable shifting with a clutch derailleur to prevent chain slap, while tubeless-compatible wheels and 2.25" tyres provide grip and durability. Dropper-ready for ultimate progression and control.

Closer look

The full story

A performance optimised aluminium frame

Built for performance, the Helion 24 features a triple-butted aluminium frameset with a CNC'd chainstay yoke that’s precision engineered to take big hits and accommodate an impressive 2.6” tyre if required. The Hellion 24 comes ready spec'd with a 2.25”/
The frame tubing has been deliberately crafted to balance strength (at the pressure points) with lightness, ensuring we don’t waste valuable grams where we don’t need it.
Threaded thru axles ramp up frame stiffness while sliding dropouts give them handling and size adjustments as they progress.

Rapid fire shifters

Simple, versatile and durable, Shimano’s Deore 5100 1x11 gives progressing riders the gear ratio they need with none of the fuss.

The simple 1x set-up is fully optimised for technical trail and jump lines without adding any unnecessary weight.

Shimano’s HyperGlide+ shifting gives quick, precise feedback and seamless shifting even under load while the Shadow+ Rear derailleur uses clutch technology to prevent chain slap and slip on the big hits.

A long, low and slack geometry.

That’s the assignment and we understood it.

The Helion 24 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 a breeze).

A no fuss, full gas chainset

The crankset and single ring set-up give the Helion 24 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 stop the chain from flapping and slipping and work in harmony with the forged aluminium 150mm cranks allowing for improved power transfer and efficiency thanks to their anatomically optimised size.

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 quick release axles makes the rare times you do need to swap tyres a breeze.

Tyres that keep you on track.

Big rips require big tyres and we’re not playing around when it comes to speccing the Hellion.
Whether you’re navigating mud, berms, ruts or roots, Vee’s tubeless compatible 2.25" Rubber Crown Gem tyres deliver traction, control and protection while still remaining surprisingly light.

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 M6000s.

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.

Drop it like it’s hot

The Hellion 24 comes engineered with the pre-installed ports and guides to accommodate the dropper post of your choice. Internal cabling keeps wires, and fail points to a minimum leaving them to focus on better descents, improved handling and even more confidence.

Happy first time buyer!

I stumbled upon Early Rider in my search for a mountain bike for one of my kids birthdays. Trying to find a performance tuned 24" bike is really hard these days! To get a lightweight frame, solid entry level drive train, good compenents and gear range for young riders, and an airfork on a 24" bike, WOW! They did it. The crazy part is I received it in the mail within two days of purchase. I was able to gift a rad bike to my kiddo, and one they are excited to ride. I am very satisfied with the product and the buying experience. It was hard to beleive that Early Rider had such a good web page that all my questions, concerns, and requirements for a bike were met, all without having to interact with a single person. The details checked all my boxes and the buying experience was world class. Some of my other kids are now asking for an Early Rider bike, and I have my eyes on the Early Rider Velio for the addition of our 7th child. Can't wait to order it when the time is right and get them riding early!

Highly recommended…

Near enough perfect condition.,2 slight marks on the brakes where I assume it was upside at one time.

My 9year old son loves it, & as it goes he’s now able to ride the bike with no help. Previous bike that he out grew he failed to ride unaided.

Very happy with the purchase. Thank you.

Good bike, poor customer support

The bike is well built, but it's a bit heavier compared to competitors. Unfortunately, we were faced with the constant problem of self-opening of the front quick release. I am used to building bikes by myself, so I know how these things work, but nothing helped and this thing was still from time to time opening. Customer service even after several urgencies never responded.

I would not buy a bike from them anymore

Great bike

My son loves the bike. Much more confident on the trails right away.

Pros:

- Good component choice. Brakes can be operated with 1 finger by a kid.

- Low weight

- Looks sick

Cons:

- Cranks seem way too long for a 8 y.o.

- Comes without tubeless tape and valves

Nice bike

Overall nicely equipped bike. Our 9 year old was jumping and riding trails right away. Of course he had some bmx skills before new bike. Nice is that all low gearing helps climbing very steep hills.
