Working on behalf of mountain bikers for 30+ years
IMBA was founded in 1988 by a group of California mountain bike clubs concerned about the closure of trails to bicyclists. Those pioneers believed that the development and promotion of mountain biker education programs and innovative trail management solutions were the key to gaining and maintaining access. The threats have evolved but IMBA’s focus on opportunities for riders has remained steadfast.
IMBA develops its Six Rules of the Trail and yield triangle to encourage responsible riding. Adopted by land managers nationwide, they help ease fears about allowing bike access to multi-use trails and are still in use, today.
The Subaru-IMBA Trail Care Crew is established. For 19 years, it educates thousands of mountain bikers and clubs on how to organize around, advocate for and sustainably build great trails across the U.S.
IMBA secures high-level cooperation agreements with the Bureau of Land Management and U.S. Forest Service, and meets with President Clinton to promote mountain biking on public lands.
IMBA launches its chapter program, establishing formal partnerships with hundreds of bike clubs nationwide. IMBA’s region directors spread out across the U.S. to directly serve the needs of local mountain bikers.
