Snow angels look a little different in Marquette, Mich. One of the snowiest cities in the country, Marquette is also “fat bike” central these days, and it’s not uncommon to find evidence in a snowdrift.

“It’s what we call a snow-bike angel here, when someone falls over on a fat bike,” said Candy Fletcher, recreation marketing director at the Marquette County Convention and Visitors Bureau. “It’s an indentation of a bike and a person.”

If that makes you smile, just try riding a fat bike. Sometimes called a cousin of the mountain bike, the fat bike features wide rims and tires with low air pressure, which provide more surface area and traction. That enables riders to take on snow, sand, loose gravel and climbs that traditional mountain bikes can’t tackle. Generally, tires are 3.7 to 4.8 inches wide, and tire pressure is 10 psi or less — about one-third that of a mountain bike. The ride is steady and slow, like, say, driving a monster truck. And, enthusiasts say, beginners and experts alike can’t help but wear a big grin.

“It’s the type of bike that makes you feel like you’re a kid again,” said Philip Keyes, New England Mountain Bike Association’s executive director. “They’re so silly looking, but they’re so comfortable, and you can run over anything.”

Fat biking originated in Alaska, and nearly a decade ago, Surly Bikes rolled out its Pugsley model, which is considered the granddaddy of the category. Since then, the bikes have gotten lighter, less expensive and more adored. The Midwest, in particular, where locals are perpetually looking for new ways to play during the long winters, is going gaga over these cartoonlike bicycles. At the Interbike trade show, in September, nearly every manufacturer had a line of them.

What to wear: Gearing up for your subfreezing ride

“The fat-bike users are the new kids on the block,” said Travis Brown, a product developer and racer for Trek. “At this point, some Nordic [ski] centers are wholly embracing fat bikes as an extra revenue source, while some are resisting it quite a bit. It’s not that different from when snowboards arrived on the scene.”

So where do all the new fat-bikers ride? The key is having a packed, or groomed trail, because even with fat tires, a bike won’t go far in powder that’s more than a few inches deep. Fat-bikers often share a wide trail with cross-country skiers and snowshoers, or they get on the narrower, twistier mountain-bike-specific trail called a single-track.

Marquette, in Michigan’s Upper Peninsula, grooms trails especially for fat biking, and the SBR (snow bike route) of its Noquemanon Trail Network is considered one of the best in the country. This year, the city is designing its own groomer, which will be dragged behind a snowmobile.

Wyoming’s Curt Gowdy State Park is starting to groom 24-inch trails for fat bikes this winter, an example of what Gary Sjoquist, an organizer of the Annual Global Fat Bike Summit and Festival, is trying to promote at other state parks. He said that with the boom in fat-bike popularity, access to trails is an increasing challenge.

“We want to show land managers that these bikes can be ridden on the trail without degrading it, and that skiers and fat bikes can coexist peacefully,” Sjoquist said. Many resorts that allow fat bikes have minimum tire-width requirements to prevent trail damage.
