I recently wanted to create a motorized bicycle that you see people with from time to time. I wanted mine to have a board track inspired look though. My father had an old schwinn frame laying around his home and figured to use it as a base. I also took up welding recently and decided this would be a perfect learning opportunity (don't judge my welds). I used all salvaged parts from old bikes except for the forks. Took about a week to finish and I am fairly happy with it.
