The Karate Monkey is Surly’s do-everything, go-anywhere, dirt-hungry steel hardtail. Whether you're chasing singletrack, strapping on frame bags for a bikepacking mission, or mixing both on one ride, the Karate Monkey keeps it rowdy, comfortable, and endlessly adaptable.
Built around Surly’s legendary steel frame with Gnot-Boost spacing, it plays nice with 142mm or 148mm rear hubs, supports dropper posts, and fits a suspension fork if you want to get wild up front. Designed for 29” or 27.5+ wheels, this frame has clearance for 29 x 2.5" or 27.5 x 3" tyres, meaning you can tailor it for trail riding, touring, or just smashing over everything in your way.
It’s the bike for riders who want a trail bike, a pack mule, and a singletrack weapon—all in one steel chassis.

Though we’re a bike shop that sells, builds and fixes bicycles, they’re really just the means to an end; albeit a beautifully designed means to an idyllic end. Our job most importantly is to encourage as many people as we can to get out and ride for transport and enjoyment. We'd love to make riding a bike as commonplace as your morning cup of coffee, which by the way is our other obsession.
Bicycle Junction is situated at 1 Marion St, Te Aro, Wellington.
