Uh, I hope you're joking. E-bikes are limited to 750 W (1 hp) and 20(?) mph unassisted top speed. "Pretending" to be an e-bike where you don't belong is going to piss off a lot of people and give e-bikes a bad rep they don't deserve. Don't do that. Besides, there may be no advantage. Think about using an e-bike as it's meant to be used, as a real-world transportation and recreation device. With the variety of places only a bicycle can go and the stamina an e-bike can give you, you might find it becomes your preferred ride. You'll live longer not only because you're not jousting with cages, you're also in much better shape. Trust me, this is nowhere near as unlikely as it sounds. Think about it.
