The latter variant is always more messy than the first. As I said, they may be bought from the UK quite easily. In fact, I am considering doing it next year. Hugh Roberts has a garage full of old Moultons and, had I not already had a bike with me when I visited him in September, I'd have probably bought one of these for my conversion project. I've spoken to that project's leader.
Project has yet to reach prototype evaluation stage, whatever that means.
I carried away a suspicion that'll be a short-wheelbase LWB priced to compete with other UK SWBs, like the KingsCycle and the Ross recumbent. Still cheap in comparison with the European suspended LWBs like the German Peer Gynt, but not within what I'd call easily-affordable range. Sorry, I know no more about it for the moment. Terminate at once. Yea, the steering tube houses a specialized rubber-stick with a spring tightly wound around it, the patented Moulton suspension system.
