Surly Karate Monkey 27.5+

Karate Monkey delivers a resilient, lively ride on all sorts of gnarly terrain. Its frame is a highly-versatile canvas for whatever dirty masterpiece your brain cooks up. 

Originally designed as a 29er (and the frame that helped spark the 29” wheel movement), the latest Karate Monkey is designed to perform just as admirably as a 27.5+ rig as well. This allows you to pick your poison — provided your poison is having a really great time, of course.

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.
