In our family we have two e-bikes - one smaller one larger, also many normal bikes, no more car. They are especially useful to get up the steep hills to the side of our valley, and also to pull shopping or dog in a trailer - up to 50kilos ok. Both e-bikes fold so they can easily go on the train. Both e-bikes were bought directly from china online, as we are not rich.
The smaller one is slower but manageable by low-teen-kids too. The larger one will go about 80km, pedalling, with small hills.
We find e-bikes don't make us lazy, rather they encourage us to make more trips, and pedal faster - still get fit.
So the european law that enforces pedalling rather than cruising is good, however the low european limit on e-bike power is unfortunate, maybe designed by people in flat countries, you need more power for hills or heavy loads.
We'd like two more to enable family trips, but those are too rare to justify the cost, and also no e-bike can last a whole day - for that we'd need solar panels on a trailer - project for later ...
