I found this video/webpage on Copenhagenize and thought it was interesting that it is more complete and more friendly than the only semiwebsite that shows any flying pigeons in the United States. If you go to the page theflyingpigeon.com you will see that they are located in British Columbia, Canada.

For being such an Icon, there are certainly not many shops in the entire North America and there are virtually no websites that display information about the Flying Pigeon. The only one in the U.S. is not dedicated to this iconic bicycle, but marely a bike shop that lists some bikes for sale.
