Sierra Eastside Mountain Bike Association
 is a 501(c)3 nonprofit organization created to enhance, preserve, and promote existing mountain biking trails – while creating new opportunities, access, and experiences for all mountain bikers in the Eastern Sierra.

Our region spans along the Highway 395 corridor from Lone Pine in the south, to Bridgeport in the north.  Our members are diverse and encompass every aspect of mountain biking and off-road cycling.  We share one common thread – passion for riding bikes, and sharing the stoke with friends old and new.
