About Appalachian Mountain Bike Club

The Appalachian Mountain Bike Club (AMBC) develops, builds, and maintains trails while providing programming to increase access to outdoor recreation.

AMBC is a chapter of the Southern Off-Road Bicycle Association (SORBA) and the International Mountain Bike Association (IMBA).


SORBA (Southern Off-Road Bicycle Association) is a member-based, 501(c)(3) nonprofit, officially chartered organization devoted to promoting land access, trail preservation and new trail development in order to enhance mountain bike touring, racing, fun, and fellowship for all mountain bicyclists in the southeastern United States. We publish the “Fat Tire Times,” to keep members informed of important issues, organized rides, work parties, races, socials, festivals and other events. We hold our mountain bike events to raise awareness of land access and trail maintenance, to ride, to race and to just have fun. Membership in SORBA entitles you to some great things— come join us!
