Dogman, i think the motor you posted is incorrect and will require some fabrication and maybe a new controller as well, to run it. This motor might have an internal controller and be a 3 phase unit.
I would contact thesuperkids.com and see what they have.

most likely the motor itself is fine. It's the internal electronics that are blown. The reason for saying this will be apparent in a moment.
the first and easiest choice would be to replace it with the identical motor. you can buy them from
if it were mine i would upgrade to the 600W BMC motor for about $30 more.
now if you find that expensive. as an alternative you may consider taking the existing motor apart and modifying it to use an external controller. one of the board members did a tutorial on how to do that:
then just add an appropriate 24V 25A or 35A controller like one from Lyen and you're out the door for under a hundred bucks plus a couple of hours labor.
it's your choice.
Rick has answered your questions fully there, you can also put the KOL motor on there as well, its a little cheaper than the BMC however the internal controllers are a bit iffy, the best bet is to modify one like I did in this video, this was spoke twistingly fast, bit of a classic old video, the unit still works I just couldnt find a wheel strong enough

if you have the motor apart, take a few good pictures of all of the wiring inside. need that info to point out your wires.
