There are a great many folding bikes following Andrew Ritchie's brilliant design which are built and sold in Asia. 3Sixty, B-Bike, Chedech, Cigna, Crosshead, Flamingo, Fova, Groo, Java, La Bici, MIT, Neo, Pico, Sanye, United and Viking are just some of the brand names. These range from slapdash copies of the Brompton Mk II up through ranges of quality to titanium and carbon fiber efforts.
