Overview
About this bike
Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. It's 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 3.0 or 27.5 x 2.8 tires, the Lowside remains capable of running either option
