Why the Arktos 125?

The New Arktos 125 is the perfect blend of fast and fun. Shorter travel means more efficiency, with a super-responsive and nimble frame. Is it a XC bike? Nah... This thing is made to be ridden hard, and built up so it can take a beating. Beat your buddies uphill, then impress the group with some full-send-ability.

The Arktos has unlocked the power of modern geo, now with improved linkage for more travel and advanced kinematics. Our signature Sine Suspension virtually eliminates ‘pedal bob’, providing instant, efficient, forward power to attack climbs, rollers and sprints.

When it’s time to get sendy, the 130mm/125mm of FOX Factory, Kashima-coated front/rear suspension punches well above its weight. 

If you like to pedal, the Arktos 125 will surely be your new favorite ride.

One Model to RIDE Them All
Conversion Kits:Quickly transform your 125 into a 140 or even a 150 (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, and any necessary links for changes.

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 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.

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.
