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
