I second this. Putting the wheel directly on the motor shaft is not good for the motor at all. Most of the time that I have seen them mounted straight to the motor shaft, the gear box shatters inside, making the motor useless.

If you would like, I can upload some pictures of some of the 4 motor drive bases that we have had in the past with our team.
