That's an excellent motor, but you can *not* reverse them simply by 
changing the polarity of the power leads.  As someone else pointed out, 
that will fry the built-in electronics.  The phrase "can be simply 
re-wired to run clockwise" probably means you can easily take the case 
apart and re-arrange the internal parts to cause it to rotate in the 
other direction.

You'll need some sort of mechanical transmission if you want reverse.
