Carrying four persons and a sewing machine, the world’s weirdest bicycle recently had a tryout in Chicago, Ill. The two-story vehicle, known as the ‘Goofybike,’ is the creation of Charles Steinlauf. It carries the whole Steinlauf family. The inventor rides at the top and guides the contraption by means of a huge automobile steering wheel. Mrs. Steinlauf sits below, operating a sewing machine, while her son pedals behind and her daughter rides on the handlebars in front. When the odd vehicle is at rest, the projecting legs of the sewing machine prevent the lofty cycle from tipping over.
