Cross posting this in NE since this area has pretty good access to this channel.

There will be a television show on Japanese bicycles on the main Japanese television networks English language channel, NHK World.
The program is Begin Japanology, and it will air next Thursday, Sept 8, various times.
It's good program that I tape and watch every week. It is about the Japanese perspective on different aspects of culture, society, technology, etc. Our local cable network carries it, but I suspect that it may be unavailable or a premium in other places. There are instructions for satellite access on their website, but they don't have podcasts available.

I expect that this show will cover the history of the bicycle in Japan, attitudes towards cycling, role in transportation, the Japanese bike industry, technological innovation and future direction of bikes and cycling. Should be worth seeing if you can.
