Prior to arrival of contemporary bicycle models, many inventors attempted to devise options to make human-driven transportation equipment that may be user friendly, light-weight, easily taken care of, and capable to competently covert energy of our muscles into more quickly motion. The main example of the precursor to the fashionable bicycle arrived in in early nineteenth century Germany, in which Baron Karl Drais and Otto Schillinger designed the human-run auto that utilized two wheels. Their wooden design and style was named Laufmaschine (translated from German as “jogging machine”), plus they secured German patent in January of 1818.
3-wheeled handcar built to be operated by only one human being, widely known in the United States as being a handcar or velocipede
, in its 25 Sept 1817 difficulty, presented a detailed description of the “new-invented travelling equipment”, detailing: "The top principle from the creation is taken with the art of skating, and consists of a straightforward thought, of impelling by the help of your ft a seat on wheels.

The dandy-horse was a two-wheeled motor vehicle, with equally wheels in line, propelled through the rider pushing along the ground with the toes as in common strolling or working.
French inventor Nicéphore Niépce created a top-adjustable seat for dandy horse in 1818, but his structure which he named “'velocipede” was never adopted by any enterprise that generated dandy horses in massive quantities.
Even this kind of an outrigger technique will not be without the need of its difficulties, as tracks which might be no longer correctly parallel — frequent on sections of abandoned track — may end up in derailment. Additional information rollers may help reduce this issue at the expense of larger bodyweight.
"Quite a few brands in France and England built their own individual dandy-horses all through its temporary level of popularity in the summertime of 1819 -- most notably, Denis Johnson of London, who utilised an elegantly curved wood frame which authorized using more substantial wheels. Riders preferred to operate their automobiles on the smooth pavements instead of the tough roadways, but their interactions with pedestrians prompted quite a few municipalities to enact rules prohibiting their use.
