Once, we were happy to scoot along on a hobby horse. Then some bright spark required a more sophisticated form to propel themselves along. This saw in an upgrade to direct pedal power. The penny farthing. Lots of crashes (enjoyed by dentists). Then breakthrough with the invention of the chain. Wheels became smaller. Bikes more stable. Improvements in materials made lighter more aerodynamic so we now have finely tuned machines we see used by the current Tour De France champions.
So it begs the question, why would someone make this?
