The Karate Monkey features updated, progressive trail geometry, our custom trumpet tubeset, and Surly's Gnot-Boost rear dropout system. Available in a variety of colors, with multiple drivetrain and wheel size configurations.

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 huge grin, of course. - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension corrected fork - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Clearance for 29" x 2.5" or 27.5" x 3" tires

As the first "plus" bike to hit the market, Krampus changed the way many people approach trail riding. It's shown people the light of how high-volume, large-diameter tires can vastly improve the ride experience. It's also done a bang-up job dispelling the myth that big tires make you slow. Krampus is kind of like the opposite of a mullet: long in the front and short in the rear. With a long toptube and compact chainstays, it takes trail-shredding abilities to the next level. A mullet may be business in the front, party in the back but Krampus makes partying its business. - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension-corrected fork - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Clearance for 29 x 3" tires

Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. Your BMX Bike All Grown Up Lowside is like the grownup version of the bike you rode when you were a kid and still had hopes and dreams and some semblance of ambition. It's just as happy riding singletrack as it is parked outside your favorite drinking establishment. Lowside is a single speed mountain bike. Singlespeeding has been a part of Surly's DNA since day one when we launched the 1x1 Rat Ride. After a lot of Homie Fall Fests and more feats of strength than we can recall, we decided to discontinue it a couple years back. Lowside picks up right where the 1x1 left off. "Some have dubbed the Lowside the ultimate pub cruiser." - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Spec'd in alternating years with 26 x 3" or 27.5 x 2.8" tires, the Lowside remains capable of running either option

The All-Around Fat Bike Wednesday sits in the middle of our Trail category, but don't let that fool you into thinking that's its only use. With Wednesday, we borrowed elements from some of our Trail and Touring models to create a versatile fat tire trail bike that can truly handle anything you want to attempt. If you do an equal amount of off-road touring as you do hitting trails, Wednesday's ability to play both parts equally will suit you well. Or, if you're looking for a fat bike and don't need the fattest tires on the market, Wednesday's 26 x 4.6" tire clearance is just the ticket.
