That said, most people don't really need to shift a lot with an ebike (again, unless you are climbing hills).

I don't know how anyone would know the "power" of your system. The power is volts x amps. You could take a 350 watt system and increase the voltage and current to get 1000 watts if you want to, and who would know? Its been done (although sooner or later somethign melts.

Or, you take a 750 watt system (48 volts) run 20 amps through it (instead of 15) and you have 1000 watts. The current (amps) is controlled by the controller, and is someone going to check your battery voltage and current from your controller to see your at 1000 watts instead of 750? (Didn't think so). Unless there is a big sticker on there saying ⚡⚡⚡ 1000 WATTS ⚡⚡⚡ you'll be fine.

Just don't go blasting down a MUP (or anywhere obvious) at 30+ mph.

FYI, a really good in shape cyclist puts out 250 watts. a 1 HP motor puts out 750 watts (e bikes are limited to roughly 1HP in your state).
I do have a lot of bad hills so it looks like maybe the mid drive is the way to go, then, for me.
