    In the subject of batteries - is it common for the stock X1 battery / controller combo to shut completely off with a battery capacity of 20%?

    I don't think I've ever heard anyone mention this 'feature' before, and this is the first time I've dipped to an actual "20%" indicated charge.

    I'm usually charging to about 80%, discharging to ~40%, but last night I did some extra riding - heading west to see "The Christmas Star". I was a couple miles out from home base and the controller/screen and all assist just shut off. No warning. The last reading I remember seeing was ~22%, so suspect it hit a magic number of "20". Did a couple quick checks to make sure it wasn't an accidental battery button push, loose battery, etc. Couldn't find anything.

    I made my non-powered way back home, I tried to turn it on a couple more times, but nothing. Gave it one last shot coasting down the last hill and the controller did come on, showing "21%" battery. Likely a bit of recovery in the cells. On the charger now, so will have to give it another check-out ride today.

    no break sensor on the X-1

    There are too many factors to give a hard number, but charging a lithium battery to 80% consistently can nearly double the total cycle count (ref 1). That makes charging to 80% a good return on investment, but you will sacrifice per-trip range, of course. Whether or not that works for you depends on your rides.

    Does anyone knows what is the battery life expectancy of the battery if you use a smart charger Luna sells for $99 to charge slowly to 80% vs. charger that came with the bike and charge to 100% every time?

    Hard to say if it is all of the 860C meters?

    I have a 750C meter from Luna and it loses time also.

    There is no comparison. The 860C meter is way nicer than the stock meter.
    You can see how nice it is in my video here

    Wow! Perfect video to watch full-screen and lose yourself on a cold, wet, gloomy Portland afternoon.

    Absolutely worth the $ for the better display, IMO. For one thing, I can now see the readout while wearing polarized sunglasses, and can make out most of the information without squinting (ie, bigger characters). Resetting the tripmeter is a breeze (just hold down + and - for a few seconds). I do worry about breaking the thing in a crash, however, due to its size and mounting position. But I'm 65 now and should probably worry more about breaking myself.

    Was it worth $90 in your opinion to upgrade the display?

    Just a note on meters displaying %.
    % is pretty useless because you don't know what the % is based on

    Li-On's can be charged to 4.2 volts
    From what I have seen on my X1 , the % is not based on that figure
    You can be showing 100% even as the voltage dips down towards 3.6 volts

    Battery voltage tells the whole story and is way more accurate

    The 860C meter upgrade can display voltage

    The display can read any integer percentage, 0-100%, believe the battery has 4 green LEDs, one red, (5 total) so possibly ~20% per LED? (unless there is reference somewhere that one green means 10-15% left??) So the display definitely has the edge in precision. Even if the LEDs are more accurate, they only have 4-5 key steps (LED on or off) so you could easily be 'in between' a step where the display is showing a pretty good representation of capacity, but the +/- 10% range hasn't been met to trigger the next LED.

    If the battery shows "one green" (and presumably the one red?) that might suggest at least 40%(?) maybe even close to 50%, with the possibility charging over 50% might tend to turn on the next LED, for three total... red, green, green, possibly indicating you're in the 60% neighborhood?

    Guess two ways to test would be to charge the battery just a bit, see if ~60% trips the next LED. Or take a battery voltage measurement and see about where you are in the charge. That could act as a referee to see if the display or LED is closer to the truth.

    Should I believe build-in battery led meter or my display?
    When my display shows that battery is at 50% my battery led meter shows only one green light(10-15%?) Which is more accurate battery led meter or the display?

    I’ve seen a few people mention creaking/popping from their X1 frames...

    Your situation may vary, but here’s what I did to correct mine.... (my wife’s small does not creak or pop, my large did from the first ride)

    I removed the rear shock (release all air pressure first and support the bike in the air) and lubed the two bolts that secure the shock to the frame. I used a white lithium grease (from my research it is carbon fiber safe). I put the grease on everything associated with those two bolts / two ends of the shock. The creaking and popping is gone.

    The two bolts had a few spots that indicated some light wear so I made sure that was well greased. I also made sure not to over tighten the bolts after reassembly. It can bind the shock...

    Hope this helps someone.

    I went ahead and ordered a Gearsensor tonight, along with the BESST tool and firmware files to flash my X-1 to 14.6, or whichever of the three firmwares offered works best. Will post Gearsensor evaluation once it's installed and bike is up and running. At which point I'll also be selling my first X-1, the medium frame. Lots of rain in the forecast . . . hope the Christmas rush doesn't slow shipments too much!
Working...
