He had several significant victories in his early years, including twice placing 4th in the American Sprint Championship, before he was drafted for six months of service in the United States Army. After his release in January 1919, Spencer continued racing, clocking victories around the world and, in 1920, setting a world record while racing in Australia for doing 0.25 miles (040 km) in 25 seconds.
Spencer became an American citizen in 1947.
He was inducted into the United States Bicycling Hall of Fame in 2005.
