96v at 19 amps vs 72v at 25 amps EBIKE!

My ebike currently goes 30mph with at 48v battery, and 33-34mph at 54v so that should tell you the windings, kv.

I think I can get 38ish mph though right at 72v 28 amps... Thats 1900w, and the genny can prolly do 2000w without tripping.

Well, cobbling together the information you've provided so far (I don't think you provided the specs of the existing controller, or battery, etc.), then I'd say maybe, but not without other changes.

Backing into the KV, for 48V and 30 mph, and then comparing with a 72V input, it looks like no.

But, if you were riding upright to do 30mph and then upped the voltage, pumped up your tires, and tucked down real low, maybe shave your legs too, then it's possible.

You can update the assumptions based on any parameters you have available if something looks off. I think the simulator uses nominal voltages, so adjust as needed. Since KV is an important input, you should get it as accurate as possible for a good comparison. You can also tweak the controller and battery to try out your 96V idea.
