Ford Think Motor Swap

Hi All,
I’m wondering if there is anyone who can answer a question for me. I have a 2002 Ford Think Neighbor. If I want to swap my Rev1 motor out for a more powerful one, can I just swap the motor or do I need to change the controller and speed sensor too? I’m hoping I’m posting in the right spot.

I replaced my motor with the bigger one that they used to sell on Ford think forum and everything worked with no issues.
