[1] Born in Wontergem, Buysse began racing professionally in 1914, when he entered the Tour de France but did not finish.

He resumed his career after World War I, entering but abandoning the Tour again in 1919 but placing third in the Paris–Roubaix classic in 1920.

Buysse, racing with his two brothers Jules and Michel, took the yellow jersey from Gustave Van Slembrouck on stage 10 by attacking during a furious storm on the Col d'Aspin in the Pyrenees.

[3] In 1926, Buysse forced the Tour de France organiser Henri Desgrange to create a new rule when he eliminated the entire field by finishing so far ahead that everyone else was outside the limit.

Desgrange extended the day's limit to 40 per cent of the winner's time and ruled that nobody in the first 10 could be eliminated.
