Video: The design of the modern bicycle seems rather obvious, right? Two symmetrical wheels attached to a simple frame. But it took a while for us to get to the streamline design of bikes today. Bicycles before were illustrious and ornate and frankly, ridiculous forms of transportation. Here is animator Thallis Vestergaard showing us the evolution of a bicycle for Visual Artworks.
The first few seconds (0:05 to 0:12) show, according to Visual Artworks:
1790, A Frenchman named Comte Mede de Sivrac says to be the first to attach two wheels in each end of a piece of wood. This creation is referred as "Velocifere" or "Celerifere"
1817, The German Karl Drais von Sauerbronn built the first steerable bicycle, the "Draisine". He's particular model is not shown in this animation though.
And it goes from there. You can read more here.
