Fortunately or unfortunately, many bikes are made in China (Mainland, Taiwan, Macau). The folding bike industry may have the last a few left with not-made in China bicycles.

Dahon has two major Chinese factories (one for exporting and one for Chinese domestic consumption) and another Eastern European factory.

You are in this business so May I ask where are yours made? In a different thread, you made a Japanese connection but I doubt they are made in Japan.

The full size bike (cheap or expensive) industry is well under the Chinese control and here is a read:

A company in ShenZhen, China can give a couple dozen of different folding bike designs and any non-Chinese company can pick which one and market under its brand.
