So far I gathered your needs are:
$1k range
Riding: street, hills, exercise
But what are your other needs?
How many miles per year? That is a lower-end drivetrain, and I suspect it wouldn't last if you are doing high miles.
What would be your avg., min., and max distances in a day? Battery size can be really critical.
What kind of hills (% grade)? You might be able to get away with a singlespeed.
At a $1k pricepoint, I'd stay away from the feature rich stuff and focus on a bike that does the core of what you want, well.
