Snark aside, e-bikes are great, I don't have one but that's because between my nice road bike that can crank out 100 miles no problem, and my battery car, I don't need one. But they do work for lots of people. I wish I could get one for my kid, but it is illegal for anyone under 14 to ride one, where I live.
Brompton bikes are one of the classic recommendations for folding bikes but there tons of other options nowadays as well.
SendMyBag do ship bikes, but I have mostly used more dedicated bike shipping services, which have been very reliable. SendBike [2] iswho I haved used in the past, but I have also had friends use ShipMyBike [3] successfully in the past. The advantage of these companies is that they will first ship you a box to use, if you dont have one already.

Access to an ebike will probably result in me taking significantly more trips with it, where I would otherwise have opted to either rent a car for an hour, or just not make the trip.
I don't have hard evidence to back up the claim, but I'm certain that an e-bike will rack up more than enough km's in a time period that the overall volume of ebike-exercise outweighs analogue-bike exercise, even if you subtract the "lost" exercise due to the e-bike assistance.
The amount of emotional and confidence boost you get from 250W of electricity honestly cannot be measured.
It's rarely the case that "we all decide that we have this very important thing to do for humanity" and focus on doing just that.
More often the benefits for humanity flow down as side effects from other more basic incentives like making money selling fast sport electric vehicles used to signal that you're rich or whatever
