Ahead of this year’s Sea Otter Classic in California, we teamed up with Wheels Manufacturing and Surly Bikes to give away a stunning singlespeed Surly Karate Monkey decked out with Wheels MFG parts. Enter for a chance to win here…
Wheels Manufacturing is supporting our 2026 Sea Otter Classic coverage this year, and we’re thrilled to bring our readers the latest from the industry later this week. Ahead of the event, the Wheels MFG team thought it would be fun to give away a bike to one lucky reader, and, with Surly’s help, they put together a stunning Karate Monkey as a giveaway. The bike is set up singlespeed and kitted out with an assortment of US-made Wheels MFG parts, including the SOLO-HG Single Speed Conversion Kit, a direct-mount chainring, a BSA bottom bracket, and more. The total value of the bike is over $2,000 USD!
The Surly Karate Monkey is a highly versatile trail bike that plays nicely with rigid forks, like this build, or 140mm travel suspension forks. It features a 100% Surly Chromoly Steel frame and fork, external cable routing, dropper post routing, Surly’s Gnot-Boost 145mm hub spacing, and a threaded bottom bracket. The Karate Monkey has big tire clearance, with room for 29 x 2.5″ or 27.5 x 3.0″ tires, and loads of mounting points for cages, racks, and bags.
The build Wheels MFG put together is an upgraded version of the stock, rigid build. It has Tektro HD-M275 disc brakes, 27.5 x 3.0″ Surly Dirt Wizard tires, a Shimano Deore crankset, and nearly everything else has been upgraded with Wheels MFG’s machined Satin Orange components. It’s a size large, which is suited to ~5’9″ to 6’2″ tall riders.
