It’s been quite some time since I’ve tested a bike with somewhat unconventional suspension kinematics. Enter the Alchemy Arktos 150 – in this case, the Arktos 150 MX. It has a mullet wheel setup and 170mm front travel paired with 150mm of rear travel. Utilizing “Sine” suspension – aptly named after a sine wave, the bike has a rate that runs regressive to progressive, then regressive again. That right there is the unconventional part, but more on the topic of kinematics later. Something that’s interesting about the Arktos lineup is just how neatly spread across the travel/duty spectrum it is.

After decades of wild experimentation and steady evolution, mountain bike frame geometry and suspension designs are approaching near perfection. It’s a truly great time to ride mountain bikes. But that doesn’t mean there’s no more room for progression; high-pivot suspension designs and gearbox drivetrains are just two examples of where things might be headed.

How does the machine from Colorado fare on the Shore?
Dec 2019 · Mick Kirkman
Well-rounded, fast trail ripper with a deeper suspension feel than its 120mm promises
Highly efficient, smooth pedaller with great climbing manners
Calm and solid feel downhill that defies the short-travel rear end
Frame feels stiff and solid
Feels so planted that the ride leans towards safe and assured, rather than pure shred-factor
Suspension jolts a tad on big hits

The Alchemy Arktos 29 isn't just a pretty face—it's got a heart of pure gold, or rather carbon fiber, and moves on the trail to kick it with the best of them.
