We had Oyama bikes in the UK for a while but I think they withdrew from the market.
Seemed to be fairly generic chinese folding bikes with slightly better components than entry level. I know they are a taiwanese company but not sure they are made in taiwan. They look very much like fuji-ta bikes but then with so many similar frames manufactured in China it can be confusing but many of the frame styles of Oyama seem to have a match in the fuji-ta range.
