Cassius Marcellus Clay, (Muhammad Ali), had his new red Schwinn bike stolen when he was 12. He found the nearest policeman and stated he wanted to whup the thief. The policeman was Joe Martin, who also trained boxers and had a gym in the basement of the building they were standing near. Martin told Ali that he better learn to fight before seeking retaliation. Ali showed up at the gym the next day and spent the next six years training under Martin.Louisville has a bike share program with 305 bikes. Five of those bikes are red in honor of Muhammad Ali.
