When I think back about the Dahon I used to have it make me appreciate the Birdy that much more, and paid less than $300 for a like new Speed P8. But like we used to say, different strokes...

The Helix looks interesting, or at least the marketing does. If they can launch it as presented at their price point it will be worth checking out. With the larger wheels and ti frame it should't require suspension to have a decent ride. Like CF, the more mainstream ti gets the better for everyone.
