Velocipede (Lat. Velox Swift And Pes, Foot), a light carriage so constructed that it may be swiftly propelled by the feet of a person mounted upon it. In its earliest form it was invented at Mannheim in 1817 by Karl von Drais, and called a draisine. As then constructed, it consisted of a bar about 5 ft. long and 6 in. wide, supported at each end upon a single wheel, the front one being so attached that it could be turned to the right or left like the front wheels of an ordinary carriage. The rider sat astride of the bar and propelled himself and the machine by the action of his feet upon the ground. The vehicle in that form did not come into use, but about 1867 it was improved and became a favorite with amateur gymnasts. A saddle was fixed upon the longitudinal bar, and a foot crank was placed upon each side of the forward wheel to serve for propulsion. The machine is kept in position by the action of the rider's body and limbs, and also by its own momentum in a certain plane. As recent examples of rapid riding the following may be cited: 1 mile in 3 minutes, by J. Keen in a match with Frederick Cooper for the championship at Queen's grounds, Sheffield, England, Sept. 18,1875; 50 miles in 3 h. 9 m. 21 s., by J. Keen at Molineux grounds, Wolverhampton, Nov. 30,1874, including stoppages; 100 miles in 7 h. 35 m. 43 s., by David Stanton, at Lillie Bridge grounds, Oct. 19, 1874; 132 miles in 17 h. 15 in., by J. T. Johnson, including all stoppages, from London to Worthington and back.
