There's no one way people use bikes and even less commonality in what folks want in a folding bike. My priorities (1) ride/fit quality, 2) carry weight, 3) fold) are not the same as others. Folding bikes which "survive" are ones that can adequately meet most needs and that stand out in at least one area. Brompton stands out in fold, Bike Friday stands out in ride quality (and weight with the Pakit now as low as 12lbs but $$$), etc. If Helix excels in ride quality with all that lovely titanium, and the fold is decent enough, and the weight can be trimmed a bit, it should be around for the long haul. I don't know that the Helix would take customers away from Brompton, but stellar ride quality at a reasonable price could make inroads into Birdy/Dahon/Tern and even Bike Friday markets. Brompton people are like Apple customers, they'll stick with it no matter what.
