I have a 2013 FX 5.7, also USED to have a 2012 XU ( 3KW ). My commute to work is 20~22 miles each way, city streets, or highway.
If I was gentle on the XU, I could make it to and from work on a charge using city streets. Freeway would require charge at work.
The FX can go to and from work on freeway on a charge, or, to and from twice being VERY gentle on city streets. Rode FX today
light cruise, not major RANGE MODE. Left for work with 95% and 80 miles projected. Arrived at work 22 miles later ( took longer route )
showing 54 miles projected and 69% battery. Charged at work. Reverse route home ( 35 mph and 45 mph limits ) driving a little slower.
Arrived home showing 60 miles projected and 72% left. I would have to believe that you could make the round trip easily on a charge
using city streets, maybe freeway. Ask your dealer if you can try it. If not THAT route, pick the bike up at the shop fully charged and
try a similar distance/ terain route around the dealership. A series of circle or square routes that decrease in size as miles are compiled
will give you the distance answer, and, since you will never be more than a few miles from the dealership, as your range gets closer to
zero, you can cut it short and head back to dealer if needed. If I recall, when you first get the last two bars flashing, you still have
about 25% left. If you hit 20 miles before you start flashing, you should be good to go.
I have been riding / driving electric vehicles for most of the last decade. The first thing that I do is a series of "laps" near my home
to find out what my MAXIMUM range can be. After that, I go on KNOWN routes to find similar information. Nothing worse than heading
out on a joy ride that happens to start out uphill and suffer range anxiety a few miles in, only to turn around and arrive back home with
plenty of charge left.
Hope this helps.
