      Somewhat. I have many opinions, but not an overwhelming level of knowledge.
      I can try to answer questions if you have them.

        Opinions? Hmmm, if you were to DIY (to wiring battery cells and everything), would you go for:

        • brushed
        • brushless DC (the triangle wave AC kind), 1 phase, sync
        • BLDC, 1 phase, async
        • BLDC, 3 phases, sync
        • BLDC, 3 phases, async
        • I don’t know the right way to call it but it’s a sine wave when you turn it as a generator, 3 phase sync

          If your main concern is simplicity, it doesn’t get much simpler than brushed DC. Just connect the battery directly to the motor (through an on/off switch) and it will run. Downsides are efficiency, fine control, and brush wear.

          Most cars use 3 phase synchronous AC motors for the best efficiency, so it seams reasonable that they would be the ideal choice if maximum range is your concern. The downsides here are cost and circuit complexity.
          You can buy something like a fardriver controller. It depends on how strict you want to be about DIY. Wiring cells is easy compared to designing and tuning a motor driver. Even tuning an existing high quality driver for your motor, transmission, and wheel is non trivial, which is why many drivers have an auto-tune button to give you sensible starting values.

          BLDC sounds like a good middle-ground, but I have insufficient knowledge or experience to make a proper recommendation.
