Hawkeye Bicycle Association (HBA) was organized in 1971 as a non-profit social club to offer an opportunity for bicycle enthusiasts of all ages and experience levels to participate in group rides and social events focused on cycling. HBA promotes bicycling safety and advocates bicycle friendly communities, roads and trails, as well as bicyclist rights.
HBA sponsors organized rides for members and guests. Club rides are scheduled on Saturday and Sunday mornings and Wednesday evenings from April through October. Shorter “leisure rides” are scheduled periodically. One "special" ride is scheduled each month (November through March).
