The latest issue of Bicycling Quarterly has a piece on Rinko bicycles. In Japan you cannot take a full sized bike on the trains, so some Japanese cyclists developed a clever way of disassembling the bike so that it will fit into a bag. I guess with practice you can do it in ten minutes. That's more time than folding a folder, but with this system you still have a full sized bike.
The BQ issue is paper and I don't think it is available on line, however if you google rinko bicycles you can find more on it.
I think it is a clever idea that may interest people on this forum (as well as the Touring and Long Distance forums) who want to tarvel with their bikes on trains.
