I do almost all the grocery shopping for our family of 4 with a Rad Runner Plus with a large basket and bag.
I love that bike. Even as someone pretty comfortable getting around on a 'regular' bike, having that extra power just makes it a really easy choice for more trips compared to the car. If it's hot out, it is so much nicer to hop on the bike and get an instant breeze compared to a hot stuffy car. If it's cold out, I can really layer up and not worry about sweating because I overdressed. I just use the motor more.
Edit: I'll add that like many things in life, it doesn't have to be all or nothing. We still have an automobile that we use, but the bike has replaced a lot of car trips. For some people a bike might not replace as many. Some might be able to ditch the car entirely. But it all helps!
