Im 74 and can't lift my leg high enough to get on my electric Mongoose any more, been working on a low seat chopper for about a year now, still got a long way to go. We run the electric bike with a on / off toggle switch. on, wide open for a few seconds then off and coast untill it slows down. It will do a little over 15 mph. tread mills have a dc electric motor ,the smallest one is over 1 and 1/2 horse power. 3 car batteries will run one, I was thinking about 4 riding lawn mower batteries. Don't give up Decon, we go slower but we still get there. And about the blood when I was younger I got blood on every bike that I had.
