Boulder Mountainbike Alliance


OUR MISSION:

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.

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.

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.
