Not an easy question, indeed. I like my 2013 BH bike very much and have never regretted buying it. On the other hand, a friend owns the same bike and his battery went bad a couple of years ago and he's never been able to get a replacement from the manufacturer or anyone else. I also recall the batteries were $600 when they were available. I saw a cheaper used one once, but I had no confidence in how many charges that one may have had left. There may be a way to repair the battery, but my friend hasn't found one and does regret his purchase. My next ebike purchase would probably be a finished one again, in part because there many more available than back in 2013; but, I know the risks and would try to cover my butt where/as possible.
