Surly

Karate Monkey Front Suspension Bike 27.5in

What Our Gearhead® Experts Are Saying:

"Few bikes inspire this kind of confidence and creativity on the trail. The Karate Monkey with a front suspension fork soaks up rough sections without compromising its nimble feel. I love how versatile the geometry is—it’s responsive, and the steel frame just smooths out the chatter. This is the kind of bike that gets better every time you ride it."

The Surly Karate Monkey Front Suspension Bike blends the rugged dependability of steel with trail-capable modern updates to deliver a ride that’s both rowdy and refined. From long backcountry loops to tight techy sections at your local spot, this bike encourages us to ride with playful intention—and maybe a little less caution. With a 140mm RockShox fork and grippy 27.5+ tires, it’s more than ready for the unexpected.

Surly’s thoughtful frame design features Gnot-Boost spacing and a suspension-corrected fork, making this an easy pick for those looking to customize or upgrade components over time. Clearance for up to 3-inch tires, a wide-range 12-speed drivetrain, and dropper post compatibility make this a reliable, adaptable rig for riders who value progression over perfection.
