I'm thinking about doing the reverse some time this summer, put some "e" in one of my city bike builds.
Just for handy reference, what is the estimated weight of electric? Somewhere I read it worked out to be a pound per mile, i.e. 20 mile capacity was 20 pounds, 40 miles=40 pounds.
And, is there any battery carrying, pannier looking, readily available attachment that would fit behind the seat? Similar to the way I do my saddlebags?
