So i overcame the math anxiety and used the power equation from "The Leading Edge" by Goro Tamai To calculate power requirements. Given a gross weight of 300 lbs or 1335 N and 0.40 square meter frontal area, at 30 mph and the Cd of 0.3 the power needed is about 360 watts. This is about 1/3 less than an bare bike and an adult rider with a Cd of 0.60.
