The mission of the Birmingham Urban Mountain Pedalers (BUMP) is to BUILD, MAINTAIN, PRESERVE, and RIDE the awesome trails in the Birmingham area. Our members, riders like you, help keep the trails in great shape and open to mountain bikers from around the world to enjoy. BUMP is responsible for maintaining over 50 miles of single track trails between Oak Mountain State Park, Tannehill Historic Ironworks State Park, and Trussville Sports Complex.  We couldn't do it without the support of dedicated members like you. Being a 501c non-profit organization, BUMP depends on membership fees, donations, and volunteer hours to continue our mission.

Please note that if you donate additional money when joining or renewing through the IMBA site, that money is split between SORBA/ IMBA (60%) and BUMP (40%).

I work at IMBA because of the amazing people in and out of the office. I get to talk about mountain biking with mountain bikers all day long and help further the mission of having great places to ride mountain bikes.
