Watercycle (Dec, 1950)
Like a strange bug, a homemade watercycle crawls across the surface of a lake or river. The weird craft was built by William Dein, an employee of the Republic Aviation Corporation. Dein purchased some surplus wing floats used on amphibious airplanes, fastened them together with a framework
and mounted part of a bicycle atop the structure. The operator pedals, and prestoâ€”the craft moves across the water.
