I got it put together today and played around some and decided to take it for a test run. I made a 20 mile trip basically pedaling the whole way. It was cold, windy and late in the day so I was hurrying. The battery was basically empty as I was pulling in home. I was also hauling some groceries so a little extra weight. I think 1 more battery would be very helpful on a longer trip.

I have a toolbox mounted to the rear rack with the battery inside. There's room for a few more batteries plus a charger. Once I get a trailer I'll be in business!
