They're missing a category for ebikes. Larger and lighter than their scooter motor, but doesn't need to hit 15kw. 3-5kw is plenty. Drone motor doesn't have enough torque for ebikes.
The main reason these motors are so powerful is entirely about high surface area allowing for cooling. For ebikes could have fat tire format but with added fairly thin mag wheel spokes, that allow for high range gear cassettes, or just placing into traditional frame designs.
