    A lot of factors go into the bike 'fit' so likely why you see conflicting opinions. Best thing would be to look at the geometry chart, and particular, the "D" dimension for the frame sizes. On top of that, you have 170mm crank throws, the seat post can extend an additional 100mm past the top of the frame, and the 'dropper' part can extend an additional 100mm on top of that. So given the "D" dimension + crank throw + seat post + dropper extension, you can calculate exactly where that would fall for a given inseam. (32" = 813mm, btw)

    Then it sort of comes down to personal preference...do you like to feel like a big guy on a small / tossable frame, or do you like to feel like you and the bike "are one", or do you like to feel like the bike is a substantial piece of equipment and you are riding along? This would guide you to the smallest frame with seat post at max extension, an average frame, or a larger frame with the seat post near minimum extensions, respectively.

    Sizing for X1 - I've read conflicting things about the sizing. I am 6'0" (32" in seam) and by the book, that should mean a large size. But reviews have said the X1 runs large, and for trail/enduro riding like what the X1 is made for, it's best to err on the small size. Per sizing chart, medium is recommended up to 5'11". I read a recent forum post by someone "6'1" or less" that said he regretted getting the medium. Anyone else in the 6'0" range regret getting a medium?

    Anyone know where I can find installation guidance for a Fisher Fab House LED installed on a Luna X-1? I'm sure someone has done one but I can't seem to locate any worthwhile instructions.

    Happy Holidays everyone.
    Well, I'm hoping that perhaps someone on this forum might be able to offer some help. I posted in the Facebook page for X1, but it seems that most folks fail to understand the issue that I am facing.
    Here is the story.
    Last Monday, I rode for about 9 miles. Put the bike away with around 80% charge left. Two days later, I go to grab the bike for a ride and the battery icon is red and indicating around 9%. I was confused, as the battery LEDs are all lit up but for one, but figured perhaps I might as well throw the battery on the charger. (at this point, I'm not thinking anything is amiss. So, a few hours later, the charger light is green, so I grab the battery (confirm all LEDs are illuminated, drop it in the bike, turn the bike on, and it is reading less than 10% charge. So I change the display to Voltage, and the bike is just above 54V. So I try to ride the bike, and there is ZERO assist. Apparently, 54V indicated means nothing if the battery icon is red (and showing empty), and the display percentage is 9% or less.
    Multiple battery reseating failed to change anything, although there were times when the percentage would jump to the mid 20% range, and even up to 60% (but it never stays for long -meaning more than 5-10 minutes).
    One of my riding buddies has a Ludi X1, and I was able to borrow his new, never used, original display (He now has the 860 like me), and the bike still failed to show a fully charged battery, or give full power. In fact, it displayed 3% and a quick ride confirmed zero motor activity. So, we then swapped in his battery (which was at 80% on his bike, ~51V) to my bike, and still no luck.
    I was certain that the issue must lie with the display, but nope. I even thought that perhaps the battery was at issue, but again, nope. My battery in his bike showed 54V and 100% charge.
    I dropped my motor, and it is dry, so not likely water related (not to mention that I have not ridden in water).
    So this is where I am hoping for some help from this forum. In my mind, there are only two possible culprits left...the signal cables and the motor. I did check the wires and connectors visually, and no signs of any damage. I have NOT pulled the wires from the downtube to see if perhaps any fraying had occurred during my rides, but with only 200miles on the bike, I find that difficult to believe.

    I did open a ticket with Luna on the same day, Wednesday, the day before Christmas eve, and got a response to the effect that they were not sure what I was describing and to take a video. So I did that, and have followed up with better descriptions (I hope). But seeing as it is the holidays, I am a bit deflated as I do not expect much follow up in the next week...which is unfortunate as this is the only two weeks that I have any time to ride much. Once New Years passes, it will be back to weekends primarily. Bad timing.
    Here is an image of the display at 54V but the battery empty. Also note that I have confirmed Voltage with a DVM.

    I should add that on the rare instances when the display shows 60%, the bike rides like it should. In fact, I was riding it in my street at 20% -which means NOT full power, demonstrating how it would not wheelie in PAS3, when apparently the battery indicator jumped up, and I did not notice and almost looped out. So, full battery or not, the power appears to be metered out based upon the percentage. The battery icon also appears to be based upon percentage and not calculated from volts.
    This is where the confusion on the X1 Facebook page is...the guys keep telling me that I can ride my bike since i have 54Vs...which is true, providing I am OK with riding around on a 48lb bike with no assist, or sometimes with partial assist, etc...

    Don't get a medium frame! I'm 6'1" or less now, with a long torso and got a medium. After a year I broke down and got a large. Up to that point I'd been able to tolerate the medium with seatpost maxed. Since starting to ride the large, I can't stand to ride the medium. All the geometry is off for me but the legs are the worst.

    I try to get the closest ride to a non-electric bike as possible, really want the exercise, but even if I didn't, it would be silly to not be able to get the best performance out of the thing.

    On a different Luna topic, I have spent many hours updating my cheapo Dell PC and I think it may finally be ready to attempt using the BESST tool.

    Thanks. That would be apprieciated.

    We can email you once we got more of that size, if you want.

    Is it listed here?

    my experience is the same as Bradleyland, below 46v better be easy on the gas or it will trip out. Dropping the battery then refitting it momentarily will re-energize for a while.

    Sounds good. Keep me posted on that M600 unit

    Will do; hoping to get to it tonight or tomorrow. UCR1 describes some changes he was able to effect: speed limit, tire size, and wheel circumference, in Desmodromic's X-1/M600 BESST thread but adds it might be better not to mess with them. As of last I looked, there was little or no reporting on how the changes played out in actual riding. (I'm having trouble articulating tonight! And inserting links.) https://electricbike.com/forum/forum...re-programming

    Thanks for the info! That likely explains it. I was pedaling hard, but also chugging up a hill in PAS 4. Would have been nice if there were some warning, indication, or read-out to show what happened, or that I was nearing a limit. Though if it is the BMS, I guess there is no communication between that and the outside world. So that is to be expected.

    Also curious that it took ~10 minutes to 'reset', though possibly it took the battery that long to recover in voltage, or possibly even a built-in 'time out' function.

    But happy to report it did auto-reset with no input or procedure needed from me, and all appears normal after giving an 80% charge yesterday and going for a ride.

    If you pull a lot of amps at a low state of charge, you can trip the BMS low-voltage protection circuit. I don't know the actual LVC (low-voltage cutoff) for the BMS in the X-1, but if you've got a Ludicrous bike, you'll want to turn the PAS way down once you're below 30% or you can draw enough amps to shut the battery down.

    This is just a general consequence of running a 4P pack with high amperage draw.

    Let me know how that programming unit works?
    Are you able to do anything besides just loading firmware's?

    BTW, regarding the brake cutoff comments above.
    You don't need brake cutoff sensors.
