But it greatly depends on your controller and the C rate of your battery. If your 1500w motor is making out the capabilities of the controller, then you won't gain any thing with a bigger motor except space in your wallet. and if the C rate of your batteries is nearly maxxed with your current motor, then you'll melt them down trying to push more power out of them.
And if your 1500W motor is being under used now by your system, then you could be adding dead weight to your bike with the bigger motor, making it slower and eating more power to get it up a hill.
Bigger motor has to be balanced with controller and battery that can handle the power, or you get broken stuff and free smoke.
