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.

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.
