Wanted a bike so built a bike.
Needed a dining table, so designed and made a dining table.
Last summer I thought it would be a great idea to build a wooden bike. Worked out all the aerodynamics, accounted for weight, size, down-force and stupidly assumed with the pedal force. If I forked out for higher grade wood I think it would have worked. That failed. I still wanted a bike so made the black fixie from scratch.
Might try the wood thing again this summer.
