This is lighter, puts out nearly equivalent power, and runs at a per volt RPM suitable to drive a bike wheel.
However if you want 30mph, this motor is EXTREME over kill. Any hub motor rated for 500w will handily do what you are looking for, at half the weight.
Also a road bike with a motor on it is going to be a mistake. You're going to need wider tires and disc brakes for one. Those frames are not designed for it. Those are made to be light weight and efficient. They fall short on eBike duty unless you are doing something that runs 20-25mph.
