In first grade at St. Pius X School, Sister Thomas gave my class a free period each week to reflect upon our sins. Inspired by a library book about sea animals, I sometimes spent it daydreaming about riding a walrus, which I admired for its immensity and the fact it could swim faster than cars were allowed to drive in my neighborhood. It conjured a feeling that was equal parts ponderous and agile; atop a walrus, I would be nimble among obstacles, yet able to plow through anything unavoidable.
Almost 40 years later, I get exactly the same feeling riding a fat bike in the Bridger-Teton National Forest near my home in Jackson, Wyo. With tires five inches wide, a fat bike is tank-like rather than tottering and able to roll over almost anything in its path. The shape of its frame — similar to that of a mountain bike, but with a wider fork and hubs to accommodate the ginormous tires — makes it agile enough to negotiate flowy, single-track trails through the trees. In the snow.
The purpose of a fat bike’s fatness is to allow it to stay on top of compacted snow. (For the purpose of this story, at least. Fat bikes can also be ridden on sand.) Compacted snow means many things: trails groomed for Nordic skiing, trails groomed specifically for fat biking, snowmobiling trails, trails packed down by snowshoers, and even snowy roads. Depending on how heavily compacted the snow beneath is, a fat bike can handle about two to three inches of fresh snow without “wallowing” — when tires, which can be studded or not, wash out because they can’t get any purchase.
“Fat biking is a paradigm shift in your head. I spent my whole life thinking, ‘I can’t ride a bike in winter,’ but once I got on a fat bike, a lightbulb clicked,” said David Hunger.
He’s known in Jackson Hole as “the godfather of fat biking” for his early and aggressive advocacy of the sport in the form of free demo days, and as the founder of Teton Mountain Bike Tours. The service offers fat-bike rentals and guided trips in the area that is home to three ski resorts, including Jackson Hole Mountain Resort, a destination resort that draws skiers from around the world.
“Fat biking and skiing are perfect counterparts,” Hunger said. “We’re not trying to take people away from skiing. When it’s high-pressure and there is no powder, those are the perfect conditions for fat biking. Instead of a bad ski day, you can have a good day riding a bike.”
Last winter, there was a two-week period when Jackson Hole didn’t get any snow. Rather than be sad there wasn’t any powder, I happily fat-biked every day. Starting from my house, I rode a half-mile on snow-covered streets to a trailhead in the Bridger-Teton National Forest. There, I turned onto a snow-covered, groomed single-track trail. Depending on how much time and energy I had, I would either ride a switchbacking trail through a forest of lodgepole pines to a saddle near the backside of Snow King Mountain, the small ski area just south of downtown Jackson, and soak in the views of four mountain ranges; an undulating trail on the forested hillside above Cache Creek, where I’d sometimes see moose; or alongside Cache Creek, on an old mining road that I shared with Nordic skiers, snowshoers and snowmobilers.
Then it snowed every day for a week, and I didn’t fat-bike once, although, by my sixth powder-skiing day in a row, my legs were dreaming of the next dry spell and the ease and mellowness of fat biking.
Not only is fat biking (usually) less physically demanding than Alpine skiing, but it’s also less technically demanding. “It’s a pretty easy sport, even for first-timers,” Hunger said. “If you have ridden a bike somewhere in your life, you can ride a fat bike.” For the easiest fat-bike ride, look for a wide, flat trail. If you want more of a challenge, seek out a single-track.
Modern fat biking’s history starts in the mid-1980s with ardent cyclists in Alaska and New Mexico building fat bikes in their garages and workshops. They welded together two (or three) of the widest mountain bike rims available at the time and jury-rigged tires to create wheels that were three to four inches wide, with the goal of riding on snow (Alaska) and sand (New Mexico) without wiping out or wallowing.
Until the mid-aughts, fat biking remained the fringiest of fringe sports, appealing almost exclusively to die-hard cyclists. And because die-hard cyclists tend toward tinkering, during this time, the bikes got better: Rims and tires got wider, and they started to weigh less.
Surly, a company based in Minnesota, a state that has about 2,000 miles of trails groomed for Nordic skiers, in 2005 released the first mass-produced fat bike, the Pugsley. I bought my first fat bike in 2010. At the time, I was definitely a die-hard cyclist — competing in road-bike races for a team sponsored by a local bike shop, Fitzgerald’s.
In Wyoming, the road-biking season is short, and Fitzy’s team members often came together at the shop to ride on indoor bikes together. Although riding in the company of friends helped the time on a trainer pass a little more quickly, it was still never as exciting as, say, watching cheese melt in the microwave.
Then one week, as I stumbled into the shop, dragging my bike and trainer, I saw a fat bike for the first time. Thinking it some kind of Frankenbike the shop mechanics had cooked up because building a bike was more exciting than watching Fitzy team members ride their indoor trainers, I laughed so hard at it that I cried.
If my childhood Big Wheel had mated with a Mars rover and the resulting offspring went crazy for carbs — that’s what I saw.
“On this bike, you can ride outside all winter,” shop owner Scott Fitzgerald told me. “You’ll see. These are going to be huge.” I didn’t believe him, but, excited by the possibility of retiring my indoor bike trainer and the probability of laughing at it all winter long, I bought a fat bike the following week.
That was a decade ago. Fitzy’s prediction about fat biking becoming huge has come true. In 2012, Grand Targhee Resort, above Teton Valley, on the western slope of the Tetons, became the first ski area in the country to open its groomed Nordic trails to fat bikers. “I was able to convince the resort’s senior leadership that [fat biking] is another amenity for our guests when there is not a lot of powder,” said Andy Williams, Targhee’s events and trail manager. In 2014, fat biking was the fastest-growing segment within the cycling industry. You could buy a fat bike at Walmart.
In 2015, Teton Valley Trails and Pathways (TVTAP) and Friends of Pathways, nonprofits advocating and fundraising for pathways in Teton Valley and Jackson Hole, respectively, began grooming summer single-track mountain biking and hiking trails for winter use by fat bikers. At the same time, Grand Targhee began grooming some of its summertime single-track trails for fat bikers. For the first time, fat bikers had trails of their own.
Fat-bike-specific trails were hugely important to the growth of the sport, because, although fat bikes are capable of riding on Nordic ski trails, if the trail conditions are not right, fat bikes ruin these trails for cross-country skiers by leaving deep gouges in the groomed snow. Because of this, Nordic centers often only allow fat bikes when “conditions permit.” Trails specifically groomed for fat biking are more compacted than Nordic trails, allowing fat bikers to ride in a wider range of conditions.
Turpin Meadow Ranch opened near Moran, Wyo., in 2016 and was Jackson Hole’s first destination Nordic ski resort. Although focused on Nordic skiing, the ranch’s founders, former Olympians Hans and Nancy Johnstone (Hans competed in Nordic combined in Calgary, Alberta, in 1988; Nancy in biathlon in Albertville, France, in 1992) welcomed fat bikers, conditions permitting, on its 12 miles of groomed cross-country ski trails. Several years after opening, the ranch began grooming dedicated fat-biking trails.
Most recently in the area, when the Caribou-Targhee National Forest, which manages much of the public land on the western (Idaho) side of the Tetons, began working with groups to design a new system of single-track trails, TVTAP was at the table from the beginning. “It was the first time we developed a trail system for both summer and winter use. All of the trails were built to accommodate winter grooming,” says Nick Beatty, TVTAP’s program director.
Although initially envisioned as a resource for Nordic skiers, the website JHNordic.com now lists fat biking as an activity and includes descriptions and details for more than 200 miles of groomed trails suitable for fat biking in Jackson Hole and Teton Valley.
The growth in fat biking is not limited to Jackson Hole and Teton Valley. Take any city — ski town or not — with snow on the ground for a couple of months of the year, and you’ll probably find an opportunity to go fat biking.
In greater Minneapolis, there are groomed single-track fat-biking trails in Theodore Wirth Park and Elm Creek Park Reserve. In Williston, Vt., Catamount Outdoor Family Center rents fat bikes and grooms trails specifically for fat bikers; it also allows fat bikes on its network of snowshoe-packed trails. Methow Valley in Washington state, which has one of the country’s largest networks of Nordic trails, allows fat bikes on trails in four different areas. The Chequamegon Area Mountain Bike Association in northern Wisconsin maintains more than 50 miles of trails — single-track and wider paths — for winter biking.
“It’s definitely true for us in Teton Valley and seems to be the case everywhere, but if you build the trails, fat bikers will come,” Beatty said. Targhee’s Williams, a former TVTAP board member, said: “I knew fat biking was more than a fad, but never imagined it would have grown so much.”
Last winter, instead of buying a season ski pass, I bought a new fat bike. I named it the Winter Walrus.
