I've been doing a lot of research into what kind of frame to use for my project, and have found myself gravitating towards choppers. While not very stealthy, (they attract attention) I like them for the following reasons:
1. Laid-back riding position for less wind resistance and comfort.
2. long wheel base for high-speed stability.
3. Wide, heavy-duty drop-outs for fat tires.
4. Lots of frame space for batteries.
5. They're cool.
Below are some websites I've come across for your perusal. I was amazed at what's out there. They run the gamut from high-end customs, to inexpensive build-your-own sites. I hope you enjoy them - lots of ideas
