OPB may never have sold a bike, but they had at least one store front, so were (slightly) more than "only a brochure". This was probably summer of 1972. I was working in a bike shop in Rocky Point, NY (on Long Island). OPB opened a store in a strip mall a few miles away (on 25A, maybe in Miller Place?) that was closed by the end of the summer. |

Did you ever go in? I ask because the brochure showed relatively pedestrian bike parts (some recognizable by brand/model) with glossy polyurethane paint in bold colors. Nothing about the presentation would have fooled an experienced mechanic, engineer or injection mold specialist. There was no serious attempt to disguise metal objects which, by their shape, could not possibly be executed successfully in polymers. Apparently the brochure was 'good enough' to swindle some number of investors. Go though the linked brochure images. It's amateurish IMHO. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Some day, plastic bicycles will take over the industry: https://www.google.com/search?q=plastic+bicycle&tbm=isch I'm not sure that includes CF (carbon fiber) because of the cost. How about an (almost) invisible plastic bicycle? http://www.instructables.com/id/The-ICycle%3A-clear-plastic-bike-with-LED-edge-light/ Never mind the garish LED's. It's the clear (invisible) frame that makes it interesting. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Maybe this is what you're thinking of: https://books.google.com/books?id=4bSABo8Akh4C&pg=PA105&lpg=PA105#v=onepage &q&f=false It sure doesn't look like it were made from any form of known plastic. Oh, now I see why: "Although this prototype had many steel parts, final model is scheduled to have plastic frame, forks, handlebars, gears, chain, hubs, and derailleur. Rim and cranks will be alloy." I wanna see the plastic gears in action. In other words, what you see in the "prototype" photo is nothing even close to what is described, planned, or expected. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
