Dude, just go buy a bike from a bike shop and get to ridin'

Here's what you are guaranteed:

1) It will fit
2) It will work
3) It will have a warranty
4) You won't have to buy tools to convert it
5) You won't have to pay someone to convert it
6) You will be riding *5 minutes* after you buy it. (not 5 weeks)
7) If you leave now, maybe you can make it to the shop before it closes tonight.

If you want it to be unique, just then customize that one.

I know this sounds harsh, but this is sort of like saying, "I saw this 65 mustang. It doesn't run. But, I need a car to drive to work and class an stuff. I don't know much about cars. Should I restore it?"

Restoring it would be great...if it were your second car/bike. If you need to get riding, buy a bike that already does what you want it to do.
