Unpopular opinion: Ride a regular bike. In terms of theft, just use a beater bike for commuting. By getting rid of the 'E' part of the bike, you'll get more exercise and won't have to worry about theft. For years I rode a beater that I found in the garbage and that I fixed up with some parts I had lying around. Later I upgraded to a singlespeed because derailleurs freeze up in the winter. It's a trek earl. Seriously…
I rented e-bikes to show relatives around, and they're fantastic if you can't or won't exercise that day. Sometimes it can make the difference between taking the bike or the car.
I see so many people on e-bikes that wouldn't ride a bicycle at all otherwise, and I think "good for them".
