Fat-tire biking (aka fat biking) is basically winter mountain biking. The biggest difference, of course, is the tires: Unlike traditional mountain bike tires, fat tires have an extra broad footprint and can be filled to a lower pressure. That gives them better stability, grip, and flotation in all kinds of terrain—including ice and snow.
By some accounts, fat bikes were first invented for the inaugural Iditabike race across Alaska back in 1987. After all, ultra-thick tires (or, in some cases, wheels welded together three rims wide) were the only way to avoid sinking in the deep snow or slipping out on ice. But it’s not until the last decade that fat biking has really started to take off as a sport. Today, you’ll find fat-biking races and festivals, as well as specialty bikes designed to handle all kinds of terrain.
Fortunately for Bostoners, local land managers and clubs have caught wind of the sport’s rising popularity. Today, you’ll find a number of Boston-area trails designed and maintained with fat bikers in mind. Here are three recommended favorites.
