Shorter trips can be handled by bike by people young and able enough to use them. And I would only take an ebike into a city where I could take it inside in order not to get it stolen.

For using bus or train for longer journeys you need an existing, reliable working and affordable service, which basically only exists inside cities. Once you need to get outside the centers, or want to get from the country into the city, you are basically f-ed.
