"About 1816, Baron von Drais constructed a similar machine, the front wheel... mounted in a fork that could be swiveled... to be steered. His... "Draisienne" or the "Draisine," several years later was introduced into England by Denis Johnson, whose improved version had an adjustable saddle, a cushioned rest for the forearms, and... different... handle bars. Known in England as the Pedestrian Curricle, the Hobby Horse, or the , this... was in vogue in 1818 and... several years afterward. Contemporary lithographs show dandies practicing on the machine in riding academies, as well as riding it over the open road (pl. 1). It, too, was propelled by the riders striking his feet against the ground."
