Oklahoma Earthbike Fellowship (OEF) is a nonprofit organization dedicated to advancing mountain biking in Oklahoma through advocacy and trail work. OEF is the Oklahoma chapter of the International Mountain Bike Association.

Join OEF through IMBA today and contribute to the trails you use! Your membership dollars pay for the tools, materials, and insurance required to keep Oklahoma mountain bike trails open. Individuals can join for as little as $39, and family memberships are available starting at $50. 


As a 501(c)(3), all donations to OEF are tax-deductible. You can donate to OEF as a whole, or to a specific trail. Contact us for more information about making a donation.
