Alright, well I haven't actually purchased any motors or wheels or anything of the sort just because I didn't want to waste money on some parts then have them not go together..
I was thinking of using these wheels

and using these motors

But again, I'm rather new and don't know to what extent those will work together (if at all). So if these don't go together, could you just suggest a cheap(ish) alternative to what I have chosen? Thanks again everybody!
