Introducing SWMMBA — the Southwest Michigan Mountain Biking Association

The Southwest Michigan Mountain Biking Association is a nonprofit mountain bike group that has been working at Fort Custer Recreational Area for 20 years. SWMMBA was founded in the spring of 1993 as a chapter of the Michigan Mountain Bike Association (MMBA) to develop trails and encourage mountain biking in Southwest Lower Michigan. As an organization, SWMMBA focuses on promoting proper trail development and maintenance, stewardship, advocacy, racing, group rides, and general mountain biking.Our group has volunteered thousands of trail maintenance hours and worked very hard to make the Fort Custer trail system what it is today. The trail system is rated in the top 50 of destinations for mountain biking in the United States.





You are now able to join again as a member of the SWMMBA, we are now an IMBA Chapter. Many of you no longer have memberships through the MMBA, so if you were a previous member of ours please sign up again via the new membership. There are a number of different optoins available to chose from starting out at the basic which is $30 on up to $1,000 for Singletrack Society members.

Simply click the link and it will take you directly to our registration page were you are able to sign up.

Thanks again for your support!


SWMMBA acts as the primary trail developer for the Fort Custer State Recreation Area located in Augusta, MI. The Fort Custer Recreation Area currently has 18 miles of dedicated mountain bike trails, with 5 additional miles of multi-use trail. Future goals include increasing both membership and mountain bike trail mileage, working with land managers in partnership to achieve this goal, and building relationships with government and business organizations to inter-connect trail systems in the region.

TRAFx Counters

We have exciting news! The SWMMBA is now installing invisible counters that will assist us with keeping track of the number of mountain bike riders that visit our trail systems every day. This will assist us in gathering data about trail usage. It will assist us to better understand and manage our trails and can also be used when applying for grants and other funding as well as assist us with working with the DNR.
