A personal tragedy inspired Reynolds to create a lasting legacy to help children. She founded the Mark Reynolds Memorial Bike Fund to honor her son, an avid bicyclist, who was killed by a mountain lion while mountain biking in California. Since 2004, she has raised more than $200,000 and donated more than 1,500 bikes and helmets to underprivileged children and given specially equipped custom bikes to children with disabilities. She also organizes many biking events that promote safety and enjoyment of the sport.
