Denis Johnson a coachmaker of Long Acre, London created an improved version of Karl Drais 's Dandy Horse in 1819 . Johnson's patented version featured an elegantly curved wooden frame, allowing the use of larger Wheels and was commonly called "hobby horse" or "pedestrian curricle" or "swiftwalker". [http://www.scienceandsocietyprints.com/barcode10438508.aspx In Johnson's model of dandy-horse, like Drais's, the Transmission was Human-powered Transport using the "natural" methods of Walking or Running , with the rider striking the feet on the ground alternately, left and right. But it led directly (albeit after a long delay) to the invention of the Bicycle in 1863 , when Pierre Lallement attached Rotary Cranks and Pedals to the front-wheel Hub of a machine modeled exactly after Johnson's.
