Perhaps it's a bit of egotism since I'm Dutch-Canadian, but I must say that the Dutch know where it's at. They have the highest bicycle use in Europe with 27% of all trips made by bicycle. And it is much, much higher than the averages in North America which are in the 1-2% range.
Aside from China, The Netherlands has the most experience with creating a bike-centric culture. And it continues in The Netherlands, whereas, in China, leaders are sadly trying to "modernize" their cities (by making room for cars and shoving cyclists off certain main routes).
The powers that be in The Netherlands have produced a quite comprehensive 'brochure' called, Cycling in The Netherlands (pdf), after repeated calls from foreigners asking how the Dutch miracle came about. It's a very good read.
Consider it the bible of how to create a sustainable bike culture. (Except somehow they left out cargo bikes as a major new Dutch phenomenon.) Oh, unless you've got hills or mountains. In that case, you might want to consult some other bike friendly place like Portland or Vancouver.
