Surly Bikes is a designer and importer of bicycles, frames, parts, and accessories based in Bloomington, Minnesota, established c. 1998. Surly is owned by and shares facilities with Quality Bicycle Products (QBP).
The company is well known in bicycle messenger and single-speed culture and helped establish the Single Speed World Championship (SSWC). Surly specializes in steel bicycle frames. Frames are made in Taiwan from 4130 chromoly steel.
Distinctive components made by Surly include the Dingle cog, cranksets with separately detachable spiders, a reversible chain tensioner, and the "Large Marge," one of the first production fatbike rims. Surly also sells lifestyle items such as wool jerseys and flasks bearing the Surly logo.
In 2005, Surly began selling the Pugsley, the first mass-produced fatbike, a mountain bike with extremely large volume tires—up to 4 inches wide—for deep snow and sand riding. The front and rear wheels share a common hub size and can be interchanged, allowing for redundancy and additional gearing combinations. Noted bicycle technical authority Sheldon Brown said, "Pugsley is, in its way, as revolutionary as the original mountain bikes were in the early 1980s."Bicycling Magazine wrote, "It's not ideal for everyday use, but it can handle a wide variety of demands and conditions well."
In 2006 Surly introduced the Big Dummy, a longtail bike frame designed for the Xtracycle Free Radical extension that can carry 200 lbs of gear in addition to a 200 lb rider. In 2016, Surly announced an updated version of this cargo bike, which they called "The Big Fat Dummy." This model is similar to the original Big Dummy, but with thicker tires, a longer top tube and a slacker head tube.
