Just wanted to point out that the Flying Pigeon's quality is improved enormously with the replacement of certain parts. This is what my shop does as a matter of course. We start by replacing the entire crankset with a Shimano UN54 bottom bracket, cotterless crank, smaller chainring, lighter pedals, larger rear cog, and better chain, and work our way up from there, replacing anything that's substandard. At $450 for a fully retrofitted 3-speed with a 2-year local warranty, I don't consider this high-priced. We're now adding 27" alloy rims with a Nexus 8-speed for something in the range of $650 (don't quote me yet on the price).
