Some dude put a pocketbike tank on his FD. This doesn't look too bad!
Maybe if you find a crapped out or wrecked pocketbike on CL or EB, you could get a tank, headlights, battery, blinker system, switches, levers, fairings, maybe even a running motor.
Most of the pocketbike engines can mount straight onto a Dax FD.
I saw someone put the fairing with headlights from a pocketbike onto a mountain bike. It was a little wierd but it worked!
I'm not sure how it is mounted though. I think most pocketbikes have 1 or 2 center tabs on the tank. Maybe he has an L shaped bracket.
