This concept bicycle from Harald Cramer. (If you click on his name you can go to his personal site and see more of his industrial designs.)
These two sentences really grabbed me: "...Each bike is custom-made which guaranties the perfect fit for every rider and simplifies manufacturing; handle bars, stem and fork are made from one piece. The ergonomically shaped seat post and saddle are integrated into the frame with a hole to cool your bum even!
I found this at NotCot.org who attributed it to the Yanko Design site: [Link]
