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.

Any idea about R Martin Electric Bikes?

I am planning to buy an electric vehicle; can you name any good suppliers in Austin, Texas area? I have heard much about R Martin Electric bikes, any idea how is it?

I'll look at the website. I've never heard of them. I have a Giant Lite electric bike that I like but like so many electric bikes, I think they stopped marketing them in the US. They are the most popular bike in Japan. Very dependable.
(Later) OK, I see that R Martin is the distributor, not the manufacturer. The bikes they have seem to be OK because their drive systems are connected through the bike's crankshaft rather than attached through a separate chain drive to the rear wheel. You need to decide if you want pedal assist which does not have a throttle and does not go unless you pedal, or whether you want one with a throttle, which you don't necessarily have to pedal.
