That bike genius, as you mention, is a company in England called Brompton. The bikes, for the most part, are hand made and sold around the world. I would say that they are making a fortune. The bike is well worth the money. I've owned many bikes over the years and this one, as far as I'm concerned, is the best that I've had. Not to mention the most fun to ride.
