My daughter just took a job in San Francisco and I thought an e bike would make a great grad gift. She is about 5' 6" tall and approx 135 lbs. not an avid biker but she did ride in previous home. But the hills in sfo are a concern so she thought better than trying to ride there. But I wondered if an e bike might be good. It would mostly be used going to/from work, groceries etc. so some ability to carry a modest pack/load is needed. And of course to make it up those hills. Thx.
