I'm looking for a bike to ride around locally. Do things like ride the farmer's market, maybe some leisurely rides in addition to errands. Possibly commute to work, if that ever becomes a thing again. Also the bike needs to carry a 5yo (even better if my 2yo also fits).

I live in Seattle and there are some steep hills in my neighborhood. I'm a 140lb woman. With a kid or two in tow, what kind of bike would I need that could sufficiently help me up hills? I don't mind pedaling, but I don't want to be a sweaty mess and tired.

I'm mostly interested in:
Rad runner
Rad wagon (but it looks like it might be overkill)
Wing freedom
Vanmoof S3
And maybe juiced scorpion

Aesthetic does matter to me and my budget is about $1500, but potentially could go up close to $2k. I love the vanmoof, but it doesn't seem as relaxed and versatile as something like Rad bikes.

Would love your thoughts for an e bike newbie!
