I live in SF and have two bikes (a road bike and a bike with a kid seat on the back), an eBike, and a car. I do lots of trips on my bike. When I am in a rush or need to go a bit farther or hillier than I feel comfortable on my bike, I often end up checking out an eBike. The fact that it's one-way is convenient but I also value that I don't have to worry about my bike getting stolen. The convenience and risk reduction is worth the few bucks to rent.
I almost never use my eBike. I prefer getting the exercise and the theft factor dissuades me from using it as a mode of transportation.
this is the way, by far my absolute favorite thing to see when visiting a city is a solid bike share program. they should be absolutely everywhere and heavily subsidized. Mexico City's version of this has been my favorite so far. the way you can get virtually anywhere in the city through a combo of Metro, bus, and bike all using the same card is excellent. It solves so many issues and uses the power of crowd funding to make it all work!
