Is it possible to make a bicycle out of cardboard?
This video shows how engineer Izhar Gafni did it, using cardboard for the frame and for the wheels and spokes.
The video glosses over how he dealt with the high stress points, such as bearings, brakes, drive system, and head tube. Surely there must be metal parts there.
