OYAMA Folding Bike
Recently I found in China a company i never heard of for folding bikes.
Bought already 2 pairs of 16".
First model was SKYLINE S-500 with Shimano FT30 cont nearly $200
second was DAZZLE S-500 which is the same model with rear suspension, I had to pay an extra of $10.
The quality is great, aluminum frame, good handcraft and light weight, about 11 Kg each.
The only problem is that the web site is only in Chinese, I don't know if you can buy them out of China.
I think they offer great models as far as the 16" series.
