If one searches the 'Search' part of the forum there is likely someone who has replaced them.
As long as the motor connector is a julet type then there should be no issue.
That controller you show is too powerful , you will need a 6 mosfet 15 or 17a controller and not a 30a model.
One will need a KT LCD for compatibility and a PAS , if the motor connector is only 8 pins one will need a speed sensor with spoke magnet.

If you're converting one that hasn't been done with exactly that controller, it would probably be better to get a controller with the block connectors so that you can test it when something doesn't work. Your pedal sensor will probably be wires out of sequence, which is very difficult to confirm unless you can get to the wires. Likewise, sometimes the motor wires are not in the correct sequence for the controller.
