I'd recommend multiple bikes. Ebikes can be inherently boring to go for a long ride on as you are essentially free-wheeling. Nothing quite like the quiet of the road as you are cycling along. Ebikes always make a whirring noise.

As a way to get from A to B quickly, nothing beats them in a city.

I did an Air Pollution piece for the BBC comparing exposure of somebody walking, cycling, and driving in and around Bath. As the cyclist, they told me I was travelling around the city a bit too fast for the pollution monitor to get all my data correctly. ;)
