Jules Pierre Suriray was a Parisian bicycle mechanic, who patented, in 1869, the use of ball bearings in bicycles. Suriray was awarded the patent on 2 August 1869.〔See: * Suriray, ("Perfectionnements dans les vélocipèdes" ) (Improvements in bicycles), French patent no. 86,680, issued: August 2, 1869 , ''Bulletin des lois de la République française'' (1873), series 12, vol. 6, page 647. * Louis Baudry de Saunier, ''Histoire générale de la vélocipédie'' (history of cycling ) (Paris, France: Paul Ollendorff, 1891), (pages 62-63 ). De Saunier points out that ball bearings had been patented both in France in 1857 by Mssrs. Courtois, Tihay and Defrance, and in the United States in 1861 (patent no. 32,604 ; issued: 18 June 1861).〕 The bearings were then fitted to the winning bicycle ridden by James Moore in the world's first bicycle road race, Paris–Rouen, in November 1869.〔 The bicycle is believed to have been built by Tribout. 〔Jules Pierre Suviray.
