Well I made it past 500km today (310 miles).
So far so good. All I've had is two annoying problems with easy fixes - a loose fuse killing the 12V power and a sticky front brake switch causing the controller cut out to remain on when the brake lever was released. Both happened in the first 200km (around 150km I think).
I've also wired my bike for bank charging. I made the Vectors small enough to fit on the bike. If I were to do it again I wouldn't bother with making them smaller. I'd just leave bank charging for home base and take along the string charger during the day.
My regular ride is a 12 mile commute. Half of that is in town and I easily keep up with traffic (I've even been known to overtake!). The second half is country roads with one 50 mph stretch - obviously traffic on this stretch backs up behind me but (a) it's never very busy; (b) I encourage them to pass me & (c) if they don't and they're holding up other folks then I just pull over for 30 seconds and let them all past. About 1.5 miles is on a dirt road, while the suspension isn't great it's not terrible either.
I haven't ridden in the rain yet (I'm allergic to water ;-) ). But there are some folks on this forum who have and have reported no great issue.
Now that I've gotten a reasonable amount of miles on it and I've not heard of an increase in failures due to some common weak point I'm gonna give the XM3K an 8 out of 10. I'd happily recommend this bike to anyone who's prepared to be an early adopter and doesn't mind doing just a little bit of troubleshooting and maintenance.
Folks who want a perfect 10 need not apply - they need to wait until Honda is selling an electric scooter. Folks happier with a 9 out of 10 should purchase one from a bricks and mortar dealer who will commit to servicing it for you.
The XM-3000 is a great bike for my 12 mile commute as long as you're happy with speeds up to 40mph. For folks who can't charge at work (a) tell their bosses to get with the program and add some outside electric outlets! & (b) roundtrip range of up to 20 miles a day would also be fine.
Of course, now I've said all these great things I'm sure something will go wrong. If it does I'll be sure to keep you posted.
If you want a short distance commuter an XM3K is a great choice. You might even consider buying one from me...
(if the moderators feel this should be moved from the XM forum to the "dealer announcements" forum then please feel free to move it!)
