You know, if those trips were going to be taken on bikes without motors, they already would. #eBikes are the bikes that don't gather dust in the back of the garage, that actually replace car trips. Some people don't need them, but the people still in cars clearly aren't those ones.
It's not going to get someone into shape to feel defeated on the way home from the grocery store, trudging up the last hill with a laden acoustic bike. Many people are not going to go ride it just for exercise. An easy car replacement, even if you barely pedal, is going to get you more active than sitting in a car. I've heard plenty of these stories from people who were able to gradually get in shape thanks to the assisted moderate effort of regular e-bike use. It just removes barriers.

@enobacon That's exactly it

Mom exhausts herself on the acoustic and then doesn't ride it for months

I tell her to get an e-bike, she says she just needs to get in shape...

@pleaseclap @enobacon Also, you can be in as good as shape as you want with ebike. You can be in better shape if that is your objective.
