Tinker Juarez Interview: Mountain Bike Legend Still Racing At 65 Tinker Juarez has probably enjoyed one of the longest careers in bike-racing history, and he's still going strong. Born in 1961 in Downey, California, Tinker has been racing bikes since he was 13, starting in 1974, at a BMX track near his home. Tinker was such a good jumper in those days that he took up riding his bike at a local skatepark.
