What's holding me back is what I read about batteries, how fragile they are and how they self destruct if you don't keep them plugged in all the time. Is this s

  Where did you read that?

  Sort of. Individual cells are usually fragile (as in, you can dent or puncture easily). However, they are usually protected by their enclosure. If you are talking about lithium cells, then you should not drain them completely. Which means that they should be kept with some charge. But, unless you intend to keep them stored away for months at a time (and maybe even then) you should be fine. There's also that fact that, when people think about batteries, they think about laptop batteries. Those are optimized for power density above all else. They are not the only type of cells available. If you are worried about safety (and charging cycles), get a LiFePo battery (https://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery https://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery). This is the same kind usually found in electric vehicles and hybrids.

    I'm not worried about safety, I'm worried about having to buy a new battery every year (at a cost of >$500) because I would use an electric bike only 6 month a year at the most, and it would destroy itself during the time I'm not using it, or if I forget to charge it for a week or two, etc.

      A lithium ion battery stored at half charge in a cool place should last perfectly fine.
