Being at the "edge" near maximum range is something I've had to deal with my previous electric bike. Yeah, I could do my one-way commute to the office always, and if something happened and I could not charge there, I could limp my way back home too slowly on back roads. But I had to be careful not to make any detours and I could not change my mind on a whim where to go. Or if I came home and decided to go out somewhere - no battery, so take the car.
Everyone is different, but my last bike, a Vectrix, had a range that was very similar to the 6.5kW FXS. It was pretty good and mostly enough. But I often wanted to have another 20-30 highway miles at my disposal, so I could go anywhere and back around my city without having to recharge half-way.
With the 12.5kW SR that I have now, the range is perfect. I've only been at the "edge" once, draining it to below 10% during a highway trip where I got lost and was in a hurry, so I drove 10-15 extra highway miles at high speeds. An hour top-up charge at work, and I was comfortable making the 10 mile trip home after that.
In MD the 9kW S is actually about $400 cheaper than the 6kW FX/FXS since the state rebate is $125 per 1 kW battery.
But the FXS was the most fun of the Zero lot for sure. And for me, the most comfortable too, along with the FX. Just I know that with this battery it won't cut it for me - it would be too limiting where I could go with it. I want to have a solid 60+ miles of highway range at full speed if needed. Not that I would want to do that too often or in one leg, but I often need to travel that many miles in a day between several office locations.
I'm really sorry I didn't get an S with more range instead of my FXS.
Yes, for my commute to work it's fine, I get home with 70-80% to spare.
However, I can't really use it to travel anywhere.
I suggest you get an S much more range instead of an FXS. The range is just too limited to be a useful motorcycle. And it's not exactly cheap.
The S also charges much faster than an FXS which requires 9 hours for a full charge.
