It's funny when you look on alibaba, you get 100s of different suppliers of folding bikes and many look identical yet the price per bike varies enormously. Some because they are reselling other factories production but others just a difference in pricing. It's pretty obvious different companies are manufacturing exactly the same geometry bikes though and from what is written they will put on any brand you want. As low as $25 for a basic steel folding bike that looks ok viewing on a web browser at least.
