Mount Wilson Bicycling Association (MWBA) is a nonprofit 501(c)(3) organization dedicated to shared stewardship of multi-use trails in the Angeles National Forest. Bringing together mountain bikers and other trail stewards, MWBA advocates for access to high-quality local trails and educates the public about sustainable trail use, maintenance, and design. Its work supports the care and enjoyment of trails on public lands.

MWBA offers several ways for people to contribute. Volunteers can join monthly stewardship events, including trailwork activities, and help maintain local routes. Supporters can donate to fund trailwork tools and food for volunteers, or become members to support trail access and mountain biking advocacy through the International Mountain Bicycling Association (IMBA). The organization also hosts events, shares updates and trailwork reports, and provides a newsletter with information about upcoming activities and opportunities to get involved. Through these programs, MWBA connects community members with practical ways to support trails and responsible outdoor recreation in the Angeles National Forest.
