Cable Drive Bicycles, by Steven Tidcomb
The original concept, the "Commuter" was the result of my senior thesis while at college. Its primary purpose was to provide a portable vehicle, to be used in combination with public transit and automobiles. It featured a flat-folding pedaling mechanism that used cable instead of the chain and sprocket system used on bicycles. The bicycle was powered by an upright riders stepping motion, which maximized visibility, comfort and safety. See details.

After college I began working on an improved design and a US Patent application. The invention gained notoriety in several trade industry publications, and resulted in founding Creative Motion Industries Inc. (CMI). I partnered with others, raised approximately 1 million dollars, formed a corporation and received U.S. and foreign patents. The companies plan was to initially introduce a compact commuting bicycle and to sub-license the Cable Drive patent to outside toy and wheelchair manufacturers. We developed the CM-1000 seen here and other products for license. See details.

The design was featured in over 60 magazine articles worldwide and TV interviews across the country including ABC's "Good Morning America". It attracted international interest including mail order magazines like Shaper Image, Hammacher Schlemmer and Abercrombie & Fitch. The CM-1000 was introduced locally through Jordan Marsh department stores. Shortly thereafter the company was unfortunately forced to cease production when the “Bank of Boston” unexpectedly called back a loan forcing CMI out of business.
