Quote:So, the bicycle wasn't invented until the 19th century... why?! At first all it was was 2 wheels and a seat. No chain, no gears, no pedals.
Not only the bicycle as such, but even more generally the whole principle of putting two (or more) wheels one after another was totally unknown before Karl Drais' invention of the Laufrad in 1817! No kind of transport vehicle in the widest sense before - carts, wagons, carriages, wheelbarrows, etc. - had had its wheels arranged in such a way. That was really a revolutionary idea. :!:
