My FXS has been a blast, really only one problem.
Range is as stated on the website, though you'll get less in really cold weather.
Commuting, I rarely get below 80% on my commute.
Only problem is the bike is so much fun, I want to ride it for a thousand miles but it can't even give me 60 on a full charge (which takes almost 9 hours).
The range will only get worse with time as the battery weakens which is really a shame.
Love everything about it except for the range.
I've had it for a few weeks and already multiple places I wanted to get to were out of my range.
I knew fully well what the range was when I bought it and it's been fantastic for my commute. But it can't give me anything beyond the commute which is a shame since I love riding it.
If you're getting one I suggest you also get the hand guards for it. They make it a lot more robust in a crash.
