In the recent years, fat tire bikes are getting quite popular. Before 2006, They were made only by custom frame-builders who liked to pedal in snow (or sand, like beaches). Then, in 2006, a Minnesota based bike manufacturer, Surly Bikes, which mass-produced the first notable bike in the “fat” genre with its Pugsley frame. They still build a lot of fat-tire bicycle models.
