Unite MY1016 Electric Motor - This is actually the MY1016-HD model which is tougher than the standard MY1016.  The mounting holes are threaded, which comes in handy since you don't have to try to reach nuts on the top (Hard to get to).  If you don't need the holes threaded, simply drill them out.

They are commonly used on various electric scooters and carts, and quite offten on Razor models.
