it's a lovely bike, i like the design a lot - simple, unique, versatile. but i would expect few changes if they were produced today - i.e. 20" wheels, no suspension, stiffer and lighter frame, decent quality parts. it should weigh less than 9kg and cost around £300 for single speed version.
i've tried couple of new moulton tsr bikes before and found them too bouncy. i'm sure there is a way to bodge something to eliminate suspension, but i'd rather have manufacturer to do that. i've asked moulton rep if they have any plans to produce non-suspended frameset, he said no.
maybe some competitor will come up with an idea?..
