Why is everything cool from Portland? And I've never been there. (and Portland Maine ain't bad either, but that's another story).
Here a great blog about city biking. http://thecitybicycle.blogspot.com/. And they talk about 650B wheels. The Jopo looks like a great bike!
But best of all is their link to Finish disco dancing lessons.
And here's a nice blog about transport bikes. It's in Dutch. I can understand some of it. But there are cool pictures no matter.
