Bobby Walthour started his career as a sprinter and developed into a formidable six-day rider, but achieved his greatest fame as a fearless motor-pacer. Walthour turned professional in 1896. He won America’s greatest race, the six-day race inside Madison Square Garden, with his partner, Canadian Archie McEachern, in 1901. Walthour again won at the Garden in 1903 with fellow American southerner Bennie Munroe. In 1902 and 1903 Walthour won American motor-paced championships. Walthour won the motor-pacing World Championships in 1904 in London and in 1905 in Brussels. Walthour’s cycling career continued until the early 1920s. (Wiki)
