About Global Fat Bike Day
Global Fat Bike Day is a grassroots cycling celebration held on the first Saturday of December, built around riding fat bikes and sharing local rides with a wider international community.
It has no need for one central event: riders can participate alone, with friends or through organized group rides.
Why Global Fat Bike Day matters
The day reflects the community culture around fat bikes—wide-tire bicycles designed for conditions such as snow, sand and soft terrain—more than a formal institutional observance.
Its origin story is explicitly grassroots, with UK riders and online fat-bike communities helping the idea spread internationally.
History of Global Fat Bike Day
Fat-Bike.com’s history credits Si Matthews with reviving a global simultaneous-ride idea and Ritchie Salt plus other UKFatBikes community members with helping turn it into Global Fat Bike Day.
Ritchie Salt’s account places the first GFBD gathering in northeast Scotland in 2012.
Contemporary Fat-Bike.com coverage from December 2012 reported that Global Fat-bike Day had just taken place and collected reader photos from rides.

How to Observe Global Fat Bike Day
Ride a fat bike on a legal, suitable route and choose tire pressure and equipment for the actual surface conditions.
Join a local group ride if one is organized, or do a solo ride and share it with the wider community.
Check trail access and seasonal rules before riding; wide tires do not remove the need to avoid damaging closed or vulnerable trails.
