Ertl was an elementary school counselor in Winston-Salem, North Carolina, and the experience got him thinking, "I bet a bunch of kids would find it fun to read while exercising ... we could get some exercise bikes and give it a shot."

The principal at his school, Ward Elementary, was on board, so he hatched a plan and put it in motion.
