draisine

Again begging the question why it took all of human history and endeavour up until this point to invent something so useful and practical and democratising as the bicycle—see previously—it was this fine day in 1817 that Karl von Drais took his Dandy Horse (Laufmaschine) out for a long and leisurely test-drive from his home in Mannheim to the Relaishaus (ironically a relief, relay station for coach-drivers to refresh their horses) in Schwetzingen, a half a day’s journey on foot reduced to one hour, speedily executed at the respectable pace of thirteen to fifteen km/h without exertion.
