When friends ride along on an electric cargo bike
We rode our bikes to Strawberry Creek Park in Berkeley for a birthday party. I saw this cute setup on a Surly Big Easy cargo e-bike. It's a long-tail cargo bike with full-sized wheels. It is great for carrying groceries, kids or other bikes, and it has an electronic assist.
The bike is set up with a Thule/Yepp child seat in the back. The panniers are also a perfect place to take a stuffed animal buddy along for a ride.
I took one for a test ride once. It felt stable even with an adult on the back rack.
