About BMA

Our Mission:

The Boulder Mountainbike Alliance's mission is to serve as a positive voice for mountain biking in Boulder County, Colorado by improving the trail experience for all users through social rides and events, advocacy, and trail building."

Great communities build trails, and great trails build community.

To fullfill this mission, the Boulder Mountainbike Alliance works towards three major goals:

Create a Community of Mountain Bikers

Part of creating sustainable trails is ensuring that there will always be a community around to care for and advocate for those trails. BMA can't do its job without a community of bikers who understand and support our mission. And we build that community around a shared love of trails, then back it up with fun social events and group rides.

BMA benefits from strength in numbers. Trail agencies listen when BMA can show it represents the vast number of mountain bikers in Boulder County. No matter how many riders regularly use the trails, we are always asked one question, "How many paid members does BMA have?" Luckily, we have a large and active community, with membership numbers that continue to grow and impress. Each and every membership helps us achieve our goals. If you are not already a member, please consider signing up today. Your voice matters.

Advocate for Trail Access

Originally established in 1991 as the Boulder Offroad Alliance (BOA), Boulder Mountainbike Alliance was formed in response to the closure of nearly every trail in the Boulder area to mountain bikes. This group became the only representative organization for mountain bikers who wanted the right to ride legally in Boulder again.

BMA has made great strides toward achieving better trails for Boulder County, achieving numerous advocacy successes, but there's always more to do, we rely on your help to do it. Check out the issue advocacy section to learn more.

Build and Maintain Trails

Our goal isn't to create as many trails as possible. Instead, our aim is to create quality trails that are both fun and sustainable, trails that will pass on our love of singletrack to future generations. BMA has developed a small army of crew leaders trained in sustainable trail building design and maintenance, and every year enlists our members and fans to work on the trails we love to ride, donating thousands of volunteer hours to the trails in Boulder County.

BMA members are young and old, professionals and students, parents and neighbors. The only tie that binds BMA members is an absolute love of trails, and the belief that together we can make things better. We believe that to be the voice of the mountain bike community, we also need to be the muscle. That's why BMA donates thousands of volunteer trailwork hours every year. Since 1991, BMA has contributed 35,000 hours of labor on trail projects, with an estimated value exceeding $500,000. BMA's Mountain Bike Patrol assists and educates mountain bikers, and helps out any trail users in need, adding an additional 2,000 volunteer hours in 2010 alone. The BMA community raised over $500,000 in support of Valmont Bike Park, and BMA has received numerous accolades for our hard work, including the Boulder County Land Conservation Partnership Program Award.

The History of BMA

Boulder Mountainbike Alliance (BMA) is the voice for mountain bike trails in Boulder County. Originally established in 1991 as the Boulder Offroad Alliance (BOA), BMA was formed in response to the closure of nearly every trail in the Boulder area to mountain bikes as a representative organization of bikers who wanted the right to ride legally in Boulder again. In 2006, we changed our name to Boulder Mountainbike Alliance to more accurately describe our focus and mission.

Since then, we have worked nonstop to gain more trail access and have had some amazing victories. If you ride now, the landscape of trails that you use are largely a result of nearly two decades of attending public meetings, designing trails and, of course, volunteer trail building efforts. To learn about our last five year's successes visit Advocacy Success.

We design, build, and maintain trails for land management agencies in Boulder County. So far, we have completed more than 165 project days which contributed more than 27,500 hours of volunteer time. This is the equivalent of providing the land management agencies of Boulder County with a full time trail worker for more than fourteen years. The value of the contributed volunteer time alone exceeds $500,000. You can see the details at Trail Projects.

In 1996, BMA started the BMA Boulder Mountain Bike Patrol as a means of helping all users in the outdoor community to safely use our trails. Bike patrollers are not “the Man,” but are volunteers who are prepared to help with bike problems, minor first aid, emergency response and, of course, provide great information about trails in the County. In 2010, our team of 63 active patrollers spent about 18,000 hours and covered almost 11,000 miles while on patrol for Boulder City, County, and the U.S. Forest Service. You can learn more at Bike Patrol.

In 2009, BMA entered into a massive project with the City of Boulder to create one of the premier off-road urban bike parks in the country. Open since 2011, Valmont Bike Park now offers kids of all ages the chance to practice all forms of off-road biking from cross country mountain biking to jumping to cyclocross barriers right in town. In support of this effort we raised over $500,000 in public donations for the design and construction of the park. For more information go to Valmont Bike Park (VBP).

BMA is a non-profit organization registered in the State of Colorado, and can accept donations as a 501(c)3 nonprofit.
