Global Fat Bike Day

Global Fat Bike Day is celebrated worldwide on the first Saturday of December. It’s the perfect weekend holiday for anyone who loves riding a fat bike—thick tires, snow, sand, mud—nothing can stop you!

History

Fat bikes combine style and function. Their oversized tires let riders tackle snow, sand, and rough trails with ease. The first mention of a bike with wide tires appeared in a 1932 American newspaper illustration, though many assumed it was a joke. In the 1990s, Alaskan craftsman Mark Grunwald stretched standard rims to accept balloon tires so riders could traverse deep snow. The idea caught on, and today major brands offer purpose-built fat-bike models with advanced components.

Interesting facts

  • Without suspension, fat-bike wheels themselves absorb bumps and uneven terrain.
  • Maintaining 25–30 km/h on a fat bike requires more effort than on a regular mountain bike—it’s the SUV of bicycles.
  • Though they look bulky, fat bikes handle smoothly once you get rolling.

How to take part

  • Ride your own fat bike—or rent one if you don’t own one.
  • Organize a fun group ride, race, or informal gathering in your neighbourhood.
  • Share your fat-bike adventures on social media using #FatBikeDay.
