The Skinny on Fat-Biking

By Tom Richardson

It’s no secret that fat-tire biking has taken off in recent years, with more and more riders discovering the joys of rolling through the beautiful winter landscape. Fat-tire bikes (also known simply as “fat bikes”) are mountain bikes equipped with big, wide, deep-tread tires, which allow them to grip the snow and ice. The tires also provide better stability and built-in cushioning, often negating the need for heavy suspension systems.

“Fat-biking actually started some 15 years ago,” says Bill Boles, Outreach Coordinator for the New England Mountain Bike Association (NEMBA), which currently has 29 chapters in the region. “But the trend has really taken off in the last five years or so. We’re excited about it because it has made mountain-biking a four-season sport. Fat bikes also provide more cushion and control than regular trail bikes, making them more attractive to beginners. Plus, fat bikes are not just for riding in the snow; they can be used year-round in sand, mud, and normal trail conditions.”

Packed snowmobile trails provide a good surface for biking across frozen lakes.

Ben Pierce, the Northeast Market Shop Coordinator with REI Co-op, points to the great trail work that’s being done by local clubs and individuals. “I attribute the growing enthusiasm for fat-biking to the support of the folks who are grooming the trails and making the activity more accessible for everyone. For example, my local NEMBA chapter promotes rides and provides access to trails, which helps break down the barriers to entry.”

Advantages of fat bikes include entry-level comfort, control, and stability not found on many “racer-breeds” of mountain bikes. Also, the super-wide tires make the bike feel like it’s equipped with four-wheel-drive. The aforementioned versatility is also a benefit; some “hybrid” fat-bike frames are compatible with regular mountain bike tires, eliminating the need to purchase two separate bikes. “On Cape Cod, many fat-bikers ride along the beaches between the high and low tide marks,” notes Boles.

“Fat-biking gives me the opportunity to recreate outdoors in the winter more frequently,” adds REI’s Pierce. “I love to ski, but when the snow conditions aren’t great for skiing, they are great for studded fat-tire bikes. Crusty packed snow is fun to roll along, and the studded tires give me some extra confidence if it’s really icy. If the trails are groomed, it’s even better.”

In recent years, many NEMBA chapters and private trail systems, especially those in northern parts of New England, have started grooming their winter trails for fat-biking (see below). In some cases, they have purchased gas-powered “Snow Dog” groomers that flatten and pack the single-track trails; in others, they simply pack the trails with snowshoes or by dragging a heavy tire behind a snowmobile.

Boles points out that fat-bike events have also become popular. Prior to the pandemic, there were some 50 events in New England geared toward fat-biking, with another five to seven large-scale gatherings, such as Winterbike! at Kingdom Trails in northern Vermont.

It’s clear that fat-biking is here to stay.

Fat-Biking Tips

  • Tire pressure is critical to fat-biking: pressure should be anywhere from 5 to 8 pounds, depending on snow and terrain conditions. Go lower in deeper snow, and bring a pump to adjust to changing conditions.
  • Many riders recommend studded tires, especially in areas that see a lot of ice and hard-packed snow. Studded tires are more costly however, often running $100 more per tire than standard models.
  • Layering is key in winter biking, given rapid heating and cooling of the body. Be sure to wear wicking layers, and bring plenty of water for dry winter conditions.
