By now you know that Pugsley was created to go where standard all terrain bikes flounder. The floatation and traction afforded by large-volume, low-pressure tires can get you over and through otherwise unrideable terrain, such as sand, mud, wet rocks and roots, ice, and many kinds of snow. Wide, low-pressure tires are easier than standard tires on whatever terrain you pass over because they don't dig in as easily.

The Big Dummy is designed for carrying cargo. Like all our frames, it's made of steel and it's got lots of little touches that you've come to love in a Surly, like clearance for bigger tires and common component sizing.
