Joking aside, it really is a case of 'do we question that?' British Leyland had some great innovations, way ahead of others (see their concept cars), but nothing really made it to production (or at least not before other manufacturers). The Brompton has some great features, and the early ones had 'ironed out' most of the traps other folding bikes fell into. If year-on-year sales were growing as fast as Brompton could keep up with demand, there is a case for saying 'don't change', but it could also be said that other people (both commercial and amateur) have had good ideas which Brompton seem overly reluctant to dismiss. I know some owners have had 'paint' problems, but I'll give Brompton the benefit of the doubt on that - maintaining or improving all aspects of painting must be very difficult with ever-changing emission regulations.
