A New Set of Wheels: Fat Tire Biking in Wisconsin

By Sam Kislia

From improved traction on dirt, to flotation when riding through snow, the over-sized tires of a fat bike let you roll where you have not rolled before.

What is Winter Fat Biking?

Some of Wisconsin’s most beautiful natural areas become inaccessible once the snow hits each winter. But a trend called fat biking is changing that! Once you see the oversized, balloon-like tires on these fat bikes, you’ll immediately understand where the name comes from. Fat bikes have extra-wide rims with low-pressure tires making it possible to cruise on soft terrain like snow.

Where Can I Ride?

In winter, whether riding groomed single-track trails, frozen lakes or fresh powder, fat bikes have extended the biking season and added a whole new twist for winter adventurers. Be aware that it is NOT legal to ride fat bikes on most snowmobile and cross-country ski trails, but there are some exceptions, so always check with the land manager before heading out. Trails often have restrictions on a minimum tire width and a max tire pressure, so normal mountain bikes don’t always qualify for fat bike trails.

The Department of Natural Resources offers guidelines about where fat bikes are allowed and the International Mountain Bicycling Association gives riders tips on fat biking best practices.
