In California there are dozens of day trips for groups with e-bike being provided. Their customers feel more comfortable about being able to keep up with the other riders as a result of having an e-bike. There are many places where one can more fully enjoy an area by being out on a bicycle instead of inside a car but before the advent of e-bike very few people even tried to bicycle at all as adults.
Having a broader cross section of people out on bicycles is good for all bicyclists when it is no longer a fringe activity. I rememer a trip down the California coast and I was waiting outside a grocery store while my companion went inside for provisions. A young boy outside asked my if I had a car and when I told him I did it was not comprehensible to him that anyone would choose to ride a bicycle instead. At the time very few adults were buying and riding bicycles anywhere and those that did were considered freeks and bicycle clothing and shoes with metal cleats (tap shoes) did not help.
