Though fundamentally simple, the bicycle is a relatively new invention, and researchers from Germany's Saarland University have developed a dandy horse using modern methods to show just how far the bicycle has come in a short amount of time.
Bicycles were first invented in the early 19th century, but they weren't without predecessors. One of the first proto-bicycles was called a dandy horse. Though dandy horses look like bicycles at first glance, one key feature is missing: the pedals. Rather than pedaling the conveyance, dandy horse riders push their feet along the ground (think of how Fred Flintstone drove his rock car.) The method is less efficient than pedaling, which is why is the bicycles ridden today ultimately won out.
