Some of you may recognize this chainless bicycle design. The bike received a lot of press coverage when it was new in the early 80s and was even featured on Good Morning America at one point. The bike’s designer, Steven Tidcomb, sent me a link to a page on his website, which provides some historical background on the design. I also want to share a bit of additional background about the bike from his message:
“It was in limited production in 1982-1983 and manufactured by Creative Motion Industries Inc, of Danvers MA. Only about 60 were sold commercially nationwide before the company closed in 1983. Beyond those 60, I was only able to rescue 8 from the assembly line before the remaining 1500 uncompleted samples were destroyed. I also rescued production quantities of most of it’s components and spare parts.
This is a very rare bike. I know of no other available samples of this bicycle beyond the few that I own and the 60 that were sold across the country. Our very first pre-production prototype was actually stolen from our exhibit booth just before our first trade show debut in Boston, in 1982. A $10,000 reward for its return for was posted in the Boston Globe but no one came forward with any information. As you can imagine, it was a significant setback for the company in terms of time, prototype expense, and lost opportunities. There are no other specimens that I can find on display in any bicycle collection or for sale. “
Steven’s website also mentions a few other possible applications for his cable drive transmission. Out of the ones he mentions, I think the wheelchair or handcycle application has the most potential. Of course, some of you may have other ideas. Steven points out that the US and foreign patents have all expired, so these ideas are now free for anyone to use.
“Perhaps they will inspire other inventors to explore how this technology may be improved and utilized for creations beyond my own.”
Great! Sharing ideas is what this blog is about, so I am happy to point you all to the information about his cable drive transmission. Thanks for sharing it Steven.
