Frame models
In 2005, Surly began selling the Pugsley, a mountain bike with 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.

Components
- Dingle cog: A two-speed track cog for fixed gear bicycles. It was released in early 2007. It is a multi-speed fixed-gear cog that is compatible with standard track hubs and lockrings. Three gear combinations are available, 17t and 19t, 17t and 20t, as well as 17t and 21t. When used with two appropriately sized chainrings, the rear axle's position in the dropouts can remain almost the same and still allow a relatively large difference in gear ratio between the two combinations. Bicycle Fixation's Harold Ikerd wrote, "The ability to change gear ratios while on the trail, road, or lost is heavenly!"
