A friend of mine has a sixties vintage Moulton in her bike collection. A three speed, It's not geared well for the hills we have around here. For tooling around the city it's perfect. Derailleur geared versions give much better performance. In the older bike the front elastmomer suspension fork is not unlike a Cannondale "Head Shock" in appearance. The rear suspension is a simple elastomer (still springy after three plus decades). I've ridden it. The suspension is effective and doesn't pogo. It's an ingenious design that deserves the cult status it's achieved.
