The bicycle is as much a work of art as it is an engineered machine. It is pleasing to the eye in a beautifully symmetrical way. It could not have been fashioned as a tool by a rhinoceros or a giraffe or even a very intelligent ape. Only human minds working in tandem could bring it from its essence to the final piece; and we are not done yet. Putting on a futurist's hat I see the arrow of time producing a flying bicycle. Battery assist and drone technology will be married to lightweight tubing (meta materials) as well as artificial intelligence to get us off the ground. I hope I live to soar on one.
