About IMBA U.S.

The International Mountain Bicycling Association (IMBA) is the worldwide leader in mountain bike advocacy, and the only organization in the United States focused entirely on trails, access, education and experiences for all types of mountain bikers in all parts of the country. IMBA firmly believes that great places for mountain biking make people, communities and landscapes better, and wants to change the world by getting more people on mountain bikes more often in more places.

IMBA was founded in California in 1988 in response to large-scale bike bans and has become the largest, most influential organization championing mountain biking in all 50 states and multiple countries. As a result of IMBA’s three decades of advocacy, education, community organizing and relationship-building efforts, mountain bikers have more access and trail opportunities than ever before. 
 
In 2018, IMBA will celebrate its 30th anniversary and is hyper-focused on the future of mountain biking. The organization is evolving significantly to respond to new opportunities that expand mountain biking to broader audiences, and continuing to develop and accelerate ways to improve the experience for longtime, passionate riders. 

Who we are: We are mountain bikers from everywhere with knowledge, expertise and passion for riding mountain bikes on great trails.

What we do (our mission): We create, enhance and protect great places to ride mountain bikes.

Why this matters: We believe in the power of mountain biking to change lives and make communities better. IMBA wants to change as many lives as possible.
