Yeah, thanks all. There are quite a few things I would have done differently.
The 36v 1000W motor is just barely enough, I think that when it burns up (as I am sure it will) I will try to (at least) double the size and get a motor with liquid cooling.
As pointed out many times 48v would have been a better choice so the last controller I purchased will handle 48v and 200A surge/100A constant.
I don't want to go faster so the gearing is right on the money, I would like more torque. I need to change pedal gearing as I would like to be able to partially assist at top speed as right now I can't keep up at anything over about 15mph.
I am very happy with it overall, It just cost way too much, I wasted a bit of cash in the learning curve but I suppose that's to be expected.
If I were to do it over again I think I would do it as a hybrid with a gas chain or belt drive motor and hub electronics.
#1 item I learned, don't wimp out and buy SLA batteries, spend the extra 100% for LiFePo4 or at least Li-Ion.
