Surly Karate Monkey MTB Bike, 27.5+, Organic Eggplant
The Surly Karate Monkey is a trail-taming steel hardtail that’s built to get rowdy. With modern trail geometry, big 27.5+ tire clearance, and classic Surly toughness, it’s a playful and capable rig for everything from technical singletrack to loaded bikepacking. The Karate Monkey strikes a balance between agility and stability, making it equally at home on fast descents, tight switchbacks, and long backcountry routes.
Finished in a bold Organic Eggplant, it looks as wild as it rides.
