This is all really good information and very much appreciated.

So if I understand what everyone is saying here is what I have and what I can do:

1. I have a sensored motor hub because I have three larger wires and also the five smaller wires.

2. I can use a sensorless controller with my sensored motor? Doesn't the hub need the controller to send the signals to adjust the sensors? I don't quite understand this one.

3. I should get a controller that is 36v but is higher in wattage such as a 36v, 800w controller. What will getting a controller with more wattage get me, more speed or just more reliability?

It is all starting to make sense to me now and I can't tell you how much I appreciate this information.
