I'd be terrified of having a $6000 ebike stolen. I'm already in my third one after having two stolen from my apartment complex, and it's wasn't in a bad neighborhood.
It could happen. I don't leave it parked outside very much - it stays in my garage at home and a lot of my uses for it are short, like dropping kids at school or taking kids to brief activity (this morning I'm talking 10yo to Kung Fu). I use a heavy chain lock with it -- I don't mind a little extra weight since the bike is already 85+ lbs.
I think of and treat this bike as my second car more than as a typical "bike".
(It's kind of funny that with the huge size of cars in the US these days, our car won't fit into the garage, so the e-bike gets to share it with a rack of computers. :-)
