Rear Hub to mid drive motor questions

[Troy86]

Forgive my ignorance. This is new territory for me, I have a himiway 750w rear hub drive bike, after some testing, it will not pull the terrain as I need, the power cable gets hot fast!
Does any one make a mid drive motor, just a basic 3 wire? I literally could use all my factory controls to power and run everything. The controller, brake switches, battery ect. I really need just a mid drive motor. I looked into Bafang, and asked their support but they would tell me nothing. I’m not sure if the hub motor is BLDC or what?

I wired the battery up on my geared hub drive with 12 ga wire, and the wire runs dead cold with 170 lb me and up to 80 lb cargo, plus 94 lb bike bags tools water. I cross >80 hills on my 30 miles commute. I had to peel a few strands back & cut them since bullet connectors come only in blue (14 ga max) but I never use more than 30 amps. Light gage ****ese crimp connectors can overheat @ 30 amps, as can a bad crimp. I use 3M, T&B, TE connectivity, Panduit, or Dorman crimp terminals.

What do you mean by basic three wire?

Also, if you get a mid drive motor, typically controller is built in it... unlike hub motor where you get a square box controller.

Yes, the motor and controller are inside the sealed housing. The actual motor is the silver round thing with the yellow, blue and green wires. The controller is the U-shaped part below it with the UPC barcode tag. The three black wires are, to battery, to speed sensor, and to display. They each have multiple wires inside. The drive shaft runs at 4,000 RPM and has stepdown gears, so the chainring goes at a normal rate. This one has the cadence sensor built into the controller and the torque sensor on the bottom bracket shaft which attaches to the pedal crank arms.
The Himiway is very heavy. A dud. Start with a lighter weight bike. A 350W bike like the one I made electric yesterday will blow away a Himiway and the $9400 bikes at bike shops. Here is the one I made electric yesterday. Note the lack of ugly wires.
