I own an older Vision SWB USS that I got from my brother in law recently. Not being able to leave well enough alone, I tore the bike apart to have it repainted. I didn't pay close attention to how the seat was attached to the set frame.
The seat frame has a cross member that goes just ahead of your butt. Welded to this cross-member is a short (3" or so) piece of tubing that comes up vertically between your legs and would cause a very unpleasent injury if one were to be thrown forward on the bike. It's like a saddle horn.
On the front of the seat bottom sling is a piece of 1/2" wide webbing with a buckle on it.
How did Vision intend this piece of webbing to wrap around the seat frame in the front?
I just checked mine, and I have it wrapped around one of the horizontial bars just to the left or right of the vertical horn. I can add a photo if you want.
A photo would be great if you could.
