So, with my trusty box end wrench set and advanced technical know-how (AKA the help of people here) I finally got my bike running!
I fabricated a seat that is more like a motorcycle seat. All I have to do to finish it is pad and cover it and add a bar on the back for mounting a tail light. I also need to put on the chain guards, zip tie all the cables, and loctite and tighten all the important bolts.
As soon as I get all that stuff done, I'll take some pics and post them. Thanks for all the help! I'm sure I'll need more. I'm considering replacing the rear gear with a bigger one for more takeoff power.
