Karate Monkey
Hardtail Mountain Bike for All Trails
$1775–2549 USD / $2449–3499 CAD
Karate Monkey is a highly-versatile trail bike that plays the part of 29er and 27.5+ equally well.
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. According to our computing machine (Thor) it can be set up in approximately 487 different configurations.
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 while permanently donning a shit-eating grin, of course.
NOTE: You can ride your bike wherever the hell you want, but this is what we think this bike is best at.
