That's a MOTHRFUCKING Dandy Horse You Got There

The eruption of Mount Tambora caused a change in world climate resulting in a volcanic winter and the "year without a summer" in 1816, during which time the price of oats rose dramatically, for example in the USA from 12 to 92 cents per bushel. This led to the starvation of many horses, which in turn led to transportation problems, which Baron Karl von Drais attempted to solve by inventing the dandy horse, the direct precursor to the bicycle.
