At the beginning of the Second World War, an unusual American bicycle took shape. To conserve metal, John T. Whalen and Webster E. Janssen of the Janssen Piano Company developed a laminated-wood-frame machine. The surviving 1942 bicycle shows how far a familiar design can change when the availability of materials becomes the defining constraint.
Its elliptical frame, fork, handlebars and even saddle were made of laminated wood; the wheels remained metal. The museum records its weight as roughly 31 pounds, or 14 kilograms. Wood was not merely a decorative covering on a conventional frame: it shaped the structure itself.
The idea never reached the market. Wood soon proved even more critical to the war effort than the metal the builders had set out to save. The bicycle remains a reminder that a sound engineering idea depends not only on form and function, but also on the resources available at its moment in history.
