interesting design but it's still a 5.2kg direct drive motor delivering 15NM torque albeit at 900 RPM. Not enough torque to drive the cranks or wheel directly, you still need a gearbox.
At the end of the day, his stator cannot generate more flux than his magnets can conduct, we go back to the quantity and quality of the magnets.
By the way, nobody manages to improve on the circle shape of the coil (like in a solenoid) in term of efficiency. Square coils are less energy efficient than round coils.
