Lowside Frameset – Blue MondaySinglespeed. Singletrack. Pumptrack.Your BMX, all grown up. The Lowside frameset captures that raw, fun-first riding style and brings it into a modern trail-ready package. It’s built for ripping dirt, cruising the city, and everything in between. Just as comfortable on singletrack as it is parked outside your local spot. Rooted in Surly’s singlespeed heritage, the Lowside carries forward the spirit of the original 1x1 Rat Ride. Simple, tough, and built to be ridden hard. Modern updates like dropper post compatibility, thru-axles, and Gnot-Boost spacing give you the flexibility to build it your way, whether you’re pulling from the parts bin or starting fresh. Run it plus, run it chunky, build it however you want. This is a platform that invites creativity. Some call it a trail bike. Some call it the ultimate pub cruiser.
