Redwood Coast Mountain Bike Association
Redwood Coast Mountain Bike Association (RCMBA) is a 501(c)(3) nonprofit organization and chapter club of the North West Regional Division of the International Mountain Biking Association (IMBA), and is dedicated to building, maintaining, and advocating for sustainable mountain bike trails and bike parks in the Northern California region. RCMBA works with local land managers, governments, and the community to maintain and increase access for mountain biking in the region. It is our goal to promote opportunities that contribute to an active and healthy community.
FREEHUB PRESENTS: A Mountain Biking Film Festival
On October 30th, 2025, Humboldt County will host FREEHUB PRESENTS, the national film festival by Freehub Magazine that celebrates mountain bike culture and supports trail building across North America. This special screening doubles as a fundraiser for RCMBA, with proceeds going directly toward building more trails in our region. Headlining the evening is our locally produced feature, “BUILDING TOGETHER: THE RCMBA STORY” a film that tells the true story of community, dirt, and determination behind the Redwood Coast’s growing trail movement. It’s more than a film night—it’s a rally point for riders, builders, and supporters to come together and invest in the future of Humboldt trails.
UPCOMING IN 2025!
