Of course the vast majority of bikes in the world don't fold or separate. In 27 years of Moulton ownership I think I've taken my apart maybe a half-dozen times, so it's very much a case of YMMV.

Moultons are probably the worst "folding" bikes ever, since they don't, in fact, fold, or come apart that quickly, or leave one with particularly small pieces. Remember here that Dr. Moulton didn't set out to make a folding bike, he didn't want his bike to be a folder and in fact has lamented the compromises necessary to create a good folding bike. Far more non-separable Moultons have been made than demountable ones over the last 50 years.

If I just wanted a separable bike, I'd probably go with a std. bike with S&S couplers or a Ritchey Breakaway. The Moulton is about something different.
