Mid Michigan Mountain Biking Association

EIN: 46-0912450


MMMBA builds and maintains trails for mountain biking, running and hiking. We share a common passion for fun and stewardship that brings us together. We work with land managers on local mountain bike trails and trail access issues. Active in outreach to engage youth and diversity of all riders and trail users. Membership revenue and donations go toward materials, maintenance, signage, and future projects that will benefit our community. In 2022 we completed a major initiative, Dirt School: A Bicycle Playground and Bicycle Skills Park located at Burchfield County Park. In 2024 we will again volunteer at community events and with youth-focused programs to help get more kids outside in nature and become confident, resilient youth via the power of the bicycle.
