Not without having it laced to a 700c rim, no, not on that Schwinn.
Buying a new rim, having custom spoked cut, and paying for the labor, will run north of a hundred bucks.
I would also recommend buying a new fork, that motor may very likely be too much for the Schwinn's--Another $125, and you should also upgrade the headset while you are at it, $50+.
Remember a 1000 watt motor is putting more power through that frame than a pro rider in the Tour de France. Wear and tear on parts needs to be considered. Fork failures and not fun.
