Citation needed? If I think of my own family, the ones without kids in their teens, 20s, 30s, 40s are ok, but the ones older than that, and the ones with young kids, I would not put on an ebike.
[EDIT] Not sure why the downvotes. I'm cycling a lot myself and am a big proponent of cycling. But am no longer able to make this my only means of transportation now that I have kids that are both too old to fit on a baby seat and too young to be going around town on their own. Family members that have respiratory and cardiovascular health problems cannot do sustained even moderate exercise. Populations are aging worldwide. Thus I don't really know that the statement is true and would like to learn more from actual data.
