Why the Arktos 150?

Like to get ROWDY when you ride? Is it all about high-speed thrills? Is bigger always better? If you answered “yes” to any of these, the Arktos 150 is definitely the bike for you. This bike takes its punishment and keeps coming back for more. With a 170mm FOX Factory 38 front suspension and 150mm rear, complemented by our patented Sine Suspension, it devours even the most brutal trails with speed, confidence and dependability. Like you, the 150 is happiest when you’re absolutely sending it! But don’t let those numbers fool you – despite its descending pedigree, the 150 will also get you to the top with surprising swiftness and agility.

Bonus: Arktos 135 and 150 models are also available in a ‘mullet’ setup, with a 29” front wheel and 27.5” rear which is gaining traction quickly in MTB, and has been used for years in motocross. The larger front hoop flows over big hits, while the smaller rear wheel provides quicker acceleration.


One Arktos to RIDE Them All:
Conversion Kits: Quickly transform your 150 into a 135 or even a 120 (and back again) with Alchemy’s conversion kits: Get two (or three) bikes in one – for a fraction of the cost of buying a second bike – and always have the ideal rig for your immediate riding plans. Kits include corresponding shock and fork.

BIKE DETAILS

ARKTOS | 150

Exclusive SINE Suspension System

The ARKTOS features the Sine Suspension System Alchemy’s patented dual-linkage platform and latest evolution of an anti-squat full suspension system.

Designed with David Earle after the Sine wave, the Sine Suspension provides next-level performance, and allows the bike to tear up climbs yet descend the roughest terrain with ease. We truly believe it is the best suspension system out there. 

THE ALCHEMY FLIP CHIP

The ARKTOS features a flip chip modification that now offers the ability to transform the ARKTOS from a capable, playful down-country bike with a steeper, more maneuverable geometry to a wickedly fast enduro machine.

‘Flipping the Chip’ changes the head tube and seat tube angle by +/- ¾ of a degree, which in turn changes the ride characteristics of your bike.

Flip to a more slack position to fit a 27.5 rear wheel for a mullet setup.

ALCHEMY PREMIUM CARBON

We have spent over a decade and countless hours perfecting our carbon layups. We engineer our frames to be stronger, lighter, and reliable. Our team of fabricators ensures our carbon bike frames are designed to be integrated with our suspension systems providing better kinematics compared to other mountain bikes. Whether it is our 5+ of NAHBs award winning carbon layups or our lifetime warranty on frames, you can rest assured your Alchemy carbon frame is built to stand the test of time. The Arktos is one of the most laterally stiff bikes ever produced. With a fully-triangulated rear swingarm, oversized suspension pivots, and compact linkage, the ARKTOS by design is made to handle anything you can throw at it. Designed and prototyped in Colorado, this bike was built to handle the rugged terrain of the Rockies.
