Radmini motor specs


I've been unable to find information about our motor on the Radmini--or the controller for that matter. Maybe someone else has had better luck...here's the info listed on the outside of the motor
BF RMC06 48v 750W(9)

What I'm interested in knowing:
How many amps are the motor and controller limits?
Does the controller use watts to limit or something else when in throttle mode?
Does the controller use cadence in PAS mode or watts or speed.
What does the setting for wheel diameter change (just speed display or ?).

Anyway, these are just questions 'cause I'm a curious guy and it's been raining for a month so I'm bored.
