Electric motors?
Hello.
I want to build an electric motorcycle by modifying a road bike to use a pair of deep-cycle automotive batteries, or perhaps capacitors or something else entirely. This vehicle is to be built on the cheap, but I want it to have high (40-60 mph top speed) performance, fair acceleration, and good range. I intend to accomplish the latter by regenerative braking, which as I understand it, would be fairly easy to do by reversing the polarity (maybe not the right word) of a DC motor through switches.
Questions-
-Where can I find such a motor? Can I pull one out of junked appliances? If so, which ones?
-What’s the best way to store power? If I do use two batteries, should they be in series or parallel? What about capacitors?
-What’s the best way to regulate power draw?
-How can I be most efficient with the power I gain by regenerative braking?
If possible, please provide links, or, preferably, a circuit diagram. I’m not really happy with the diagram I made.

I’ll tell you what, I built an electric bike with a Rigid powerdrill, the motors are pretty strong, more torque than anything else on the market (powerdrill wise), and so long as you don’t lug them below 1/2 max RPM for too long (pick your gear ratios wisely) they hold up well.
