The Flintstones motorcycle?

We just came across this on the web and look at it as to a prehistoric motorcycle (yes, even though it is actually a bicycle from 1791), especially after reading that it’s form was inspired by animals such as horses, birds and snakes.

Invented by frenchmen, Comte Mede de Sivrac this early precursor of the bicycle => motorcycle had no steering and we can’t see any pedals, so we guess that Fred Barney would easily find its place on it and ride with style. thx to topspeed.com
