The new Boosted Mini X has the XR (extended range) battery, with a top range of 14 miles. The X is also US$999, versus US$749 for the Mini S with its 7 mile top range.
This guy tries the Boosted XR battery in NYC. It includes a ride up the west side bike path, so this is of personal interest to me.
