Fat Chat Group

Mark was an unlikely fat bike owner. Last year when his new road biking hobby was cut short by “the dang Wisconsin weather,” Mark brought out an old hybrid. A wider tire with more grip is good enough, right? Plus, a second new bike in nine months didn’t seem practical.

Everyone else brought out their fat bikes.

As snow flew and riding the hybrid became out of the question, Mark learned more about Fat Bikes from his fellow Tuesday Nigh Chat riders and Bike Doc staff. He started to weigh the uses for the bike beyond weekly snow rides.

Rides & Races

John Mueller, customer and part-time service tech at the Bicycle Doctor signed up for the Hugh Jass Fat Bike Series, a six part race put on by Wheel and Sprocket. "I'm looking forward to having some rowdy competitive fun at a unique event. It's a reason to unplug and get outdoors in the age of indoor training."

John says, "These races are my first experience with off-road racing, so the lighthearted nature of the event helps take off the apprehension off doing something new."
