The International Mountain Bicycling Association (IMBA) is a 501 (c) 3 non-profit educational association whose mission is to create, enhance and preserve great trail experiences for mountain bikers worldwide.

Since 1988, IMBA has been bringing out the best in mountain biking by encouraging low-impact riding, volunteer trailwork participation, cooperation among different trail user groups, grassroots advocacy and innovative trail management solutions.

IMBA's worldwide network includes 35,000 individual members, more than 750 bicycle clubs, more than 160 corporate partners and about 600 retailer shops. IMBA's members live in all 50 U.S. states, most Canadian provinces and in 30 other countries.
