Hi Ingrid. I'd highly recommend looking at the YUBA El Mundo: hhttp://www.ebikelane.com/products/yuba-elmundo-bionx-electric-cargo-bike it's a great cargo bike, easy to ride and powerful for SF hills with room for your child as well. My son is 7 and he has enjoyed riding on the back of a El Mundo many times.

Can't seem to use keyword search to find recommendations for a mother needing to carry kid and groceries through San Francisco Hills.
