Looking for 1 motor for a 6S board

I’m fixing up a board due my son to ride. It’s a basic setup with (2) 6S 6Ah lipos in parallel and a hobbywing MAX8 esc.
Just looking for a motor that will allow him to get some experience and enjoyment out of it, definitely don’t need anything top of the line.
If anyone has something laying around that might work for this, please let me know.

get an skp6355 a cheap vesccc and limit power
