Fwiw, when considering multiple batteries be aware that swapping frame-hung packs can be a fiddle and the plug connectors are not really designed for that kind of repetitive duty. If the resulting wiring maintenance would not be enjoyed, it might be wiser to get a single battery sized to fit your need.
Hmm, my plan was to only mount the motor wheel likely once a week when I ride with my adult son (to keep up). Otherwise I prefer to ride with my traditional wheel (and bike weight). I would leave the wiring on the bike and just remove battery and wheel. Are you suggesting the wiring might not stand up to this sort of use? Good thing to know before I buy.
As for batteries, I would start small I think, and then do what you suggest if/when I need more range. My interest in keeping the weight down is I have to carry the bike up stairs to public transit.
