BMA is the positive voice for mountain biking in the Boulder Colorado area
The Boulder Mountainbike Alliance’s mission is to serve as a positive voice for mountain biking in the greater Boulder Colorado area by improving the trail experience for all users through social rides and events, advocacy, and trail building.
We Create Community
BMA connects you to other members of the mountain biking tribe and shares the trail love by offering social events, group rides, skills clinics, and more.
We Build More Fun Trails
BMA works on trail expansion and improvements. We partner with land managers to make the projects happen. Our goal is to have more great trails available for all types of riders.
We Advocate for Access
BMA has made great strides toward achieving better trails for Boulder County with numerous advocacy successes, but there’s always more to do. And we need your help to do it.
Our organization was founded in 1991 as a grassroots solution to preserving local trail networks from closing to mountain bikers.
BMA has become a force dedicated to the mountain bike community. We are leading initiatives to build, maintain, and ride more fun trails.
Contributing over 2,000 hours of volunteer labor in 2018, BMA is an important partner to public land managers across the state.
Our expansive network of dedicated volunteers stands ready to build, teach, lead rides, and advocate for trails throughout the year.
