Hey JFleck, the seat came from a bike shop that closed down about ten years ago. It's attached with a welded front swivel mount on the bottom front of the seat, while the rear spings are attached to a custom extension that is welded to the rear of the bike frame... which also attaches the rear bobbed fender, the other half of the fender was used for the front.
No, jeffspeeder I've never raced in the death race. The bike handles really good, I've been clocked at 43-45 mph. The bike's in pieces right now. I'm gonna have the frame stregthened and re-welded. I'm working on a vintage schwinn frame right now, it has the motor from the black bike you see in the photos. If the boardtrack comes back it will better than it was before!
