Hi All, it seems there is more than one model of Dahon Dove. I have one that was originally bought new in China, brought to New Zealand by an immigrant family, and then sold to me hardly used. It has a different frame to the ones in the pictures above and has an 8 speed derailleur. It came with the seat post pump. It is a China only model, and is painted in a purple shade with yerllow lining. Looks very smart and rides nicely. My wife and I took both our Dahons with us on a trip to America and Europe, with a two night stopover in Tokyo on the way home. In the US we hired campervans (RVs) for some of the time and found the bikes very useful in places like Yosemite and Grand Canyon natonal parks. In Europe of course the cities are very bicycle friendly, we used trains for long distance travel and the bikes for local exploring. We didn't do much biking in Tokyo, but it is more bicycle friendly than we thought it would be. We hope to do a longer trip there sometime and will take the bikes again.
My wifes bike is a 20 inch, dahon Eco C7. Being a bit bigger it does not pack wite so easily into an airline size bag, but we managed OK and did not get charged any excess baggage on any of the flights.
