I' am in contact with some of the main folding bike frame manufactories in China. Regarding the mentioned brands, FSIR, CRIUS, LITEPRO, FNHON...... if you guys have any question, I would like to help you to get more information.
Great to know that. I would like to buy in spring one or two fnhon bikes (Blast frame, 18 speed, vbrakes) but I live in EU so the question is if they could produce such bikes for me and ship to Europe with their own way to avoid 23% VAT and customs.
