So I picked up this 50's Schwinn for 20 bucks. Rusty & greasy, but it's got a solid frame.

I decided that I would give it a sex change, rake the neck, mount a pocket bike motor and a 17" Honda (trail 90) rear wheel into it.

I'm going to try my hand at fillet brazing, but I want to practice a lot before I touch my bike. I want to preserve the patina wherever possible. I'm planning on using a thumb throttle, so I can retain the O.E grips.

Needs a new front rim & spokes. I'm hoping to keep the Schwinn model 200 hub.

Going to drill out a 44T bicycle drive sprocket to fit onto the Honda rear hub.

Just for the heck of it, I'm going to be making the exhaust pipe out of copper.

As for the crank set.. I don't know. Maybe use a forward mounted electric assist?

Just for fun, I'm gonna flip the lid. Run the exhaust out the top. As you can see, there's a Ton of porting and polishing work to be done.

After porting, I'll be able to run a 1 1/4 inch copper header pipe. Should sound pretty fun.

Got the motor mount roughed out. Still needs to be trimmed, drilled and brazed on. The engine will be on a separate (adjustable) aluminum plate that gets bolted to the beam. Here's the motor in mockup, sitting on a board.
