Thinking about how to make a good hill climbing motor for at least 450lbs (total combined weight) on a 9% grade at about 13 to 15 mph, with a long-tail cargo bike, got me to thinking about trying an axial flux motor as a mid mount motor mod, with a large reduction to the drive wheel.
I can't get the people at the BionX to even admit that the D500 is an axial flux motor. Does anyone know if it is?? They don't make this in 750 watts do they?
Maybe I should be looking for an asymmetrically wound motor, not that any of this exists except as an experimental over priced machine. Maybe there is a DIY motor kit?
Well a simple brushless 750watt motor is not the worst thing to use. If it were not controlled to our states limit of 900-1000w. 1200 to 1500watts maximum for a few minutes, would be ideal.
But what direct drive hub motors would be slow enough to work with a doable reduction for a 24”-26” diameter tire, and still be powerful enough?
Low rpm winding motor, like a mac 12t, but with out the planetary gears?

12 turn low speed extra torque motor - 200rpm loaded at 36V ??
or should I be looking for a differnet kind of motor altogether?
