    [QUOTE=F1PRB22;n112344]

    Same issue with my bike at 322 miles in , probably 22 of those miles gentle offtrail since I am a beginner, the rest of the miles on a groomed bike path. Noticed wheel had slight wobble before ride, then saw bolt was hanging half way out, so saved bolt, but lost matching nut. I believe this could have led to a serious accident. Blue loctite covers the threads, but it evidently isnt enough. Everyone should be aware of this issue ![/QUOTE

    I have around 1500 miles on mine so far without any loose bolt issues
    I am pretty sure I went over all the bolts when I got the bike

    With two post here about this issue, I think it's a good idea for everyone to check their X1's
    The Blue Loctite is good to use for bolts that you may want to loosen at a later date.

        eskachig the trucking company has scheduled the delivery to us for Friday. Thought you might want to know. Once they get here we can start modding them. Any bikes that were ordered with zero modifications will ship within probably first couple business days after arrival. If you got mods, maybe a few days after depending on where in the preorder queue you are (people that have waited the longest get priority)

        Thank you for the update.

      Can anyone recommend an adapter for the front forks to enable them to fit a standard fork mounted cycle carrier? I’ve struggled to find one.

      Is there a specific torque wrench best to use with the Luna X1? With all the issues with bolts coming g loose it seems a torque wrench will be completely necessary to go over bike b4 each ride. Also sounds like the blue lactate helps but may not be the cure all?

      I removed the throttle from my X1
      Never used it
      My dash is really clean
      Just the controller and the drop post lever

        looking good.....very clean...and I see you got the upgrade on the display - smart choice!!! I am waiting patiently for my x1 to arrive but I am very curious of the PAS levels and how smooth they are? I have a Bafang m400 currently and it is real smooth, no jerkiness in any of the levels, not super powerful but gets the job done!

      I have a new Bomber coil shock sitting around waiting for the bike to arrive, but I realized I forgot to order mounting hardware for it. Can I reuse what's currently on the bike? The eyelets are fairly standard across the industry, right?

        I put a Fox DPX2 on, and couldn't use the mounting hardware from the old shock... The spacers and bushings didn't mesh properly. So I had to order mounting hardware m8x21.84. Give it a try though, you might have better luck than I did.

        Thanks for providing the size, I ordered a hardware kit too. Easier to just spend the $15 now, imo.

      I just use a wrench and see it if bolts are tight enough.
      Never really had to have a torque wrench in my 40+ years of building and working on bikes

        40 years of wrenching on bikes goes a long way. You've got a solid feel for these things, honed by decades of trial and error.

        Studies have shown that professional mechanics can often approximate a torque rating without a torque wrench - but they also tend to use one. Occasional hobbyists are all over the place. With things that are surprisingly easy to crack or crush with overtightening like carbon, using a torque wrench is a great safety net - and also helps build that muscle memory. The "error" part of that equation just starts getting too painful.

        A couple of decades of wrenching on motorcycles made a big believer in following manufacturer torque specs to the letter no matter how bizarre they are (BMW, I'm thinking of your goofy 20NM + 180 degrees bolts). Your life is on the line in that sphere.

      Where can I get a derailleur hanger from for the X-1 enduro?

        You can email support@lunacycle.com and special order one. It is also worth bearing in mind that a hanger can be straightened multiple times before it needs replaced.

        How do you bend them back?

        There are videos on YouTube showing how to do it

      I own the Park derailleur tool that lets you adjust the hanger so that it is exactly parallel to the wheel
      It has paid for itself many times over in the last 20 years
      The hanger can be off horizontally and vertically

      If you want to get it aligned right, any bike shop can do that for you.

      This is how the tool works

        Any chance Luna will provide ability to flash the latest Bafang firmware for the M600? I've read it is much improved in terms of both smoothness and efficiency. I find my X1 (non-ludi) almost unusable at lower PAS (1-2 of 5). I believe this is the Luna tuning as the bike is fine at higher PAS (3-5 of 5). I would like to purchase the BESST tool (approx $100) and flash the latest firmware from Bafang. I contacted FLX and they provide the BESST tool for their customers and allow programming. They said they would NOT sell the BESST tool unless the motor was purchased from FLX. How about it Luna? Can you please provide this option. Now that Luna is offering proper 150mm cranks the only thing holding this bike back is the Luna tuning (at least on the non-ludi M600).

          That would be great. I do have the Ludacris mod, and find the abrupt torque to be unusable in any off road situation. If Bafang has a software update, I would buy a $100 tool to change the settings. Or even pay Luna $100 or $200 for an appropriate tune.

          Does this latest batch of X1s come with the new Bafang firmware - the non-Ludi versions anyway?

          Hi paxtana, I have followed up with Eric but got no reply. I will reach out again.

        The longer I wait for the bike, the more crazy thoughts I keep getting.

        Anyone ever do a single speed conversion of this beast? I bet there is meaningful improvement in suspension feel. Something like a 32x20 gearing should keep things pretty efficient.

        Comment


          I seen someone comment on another forum. It is EXACTLY the same behavior I experience with my Luna BABE with M600 non-ludi.

          Quote: As far as torque sensing. I think Luna did something to the M600 tuning that makes the torque sensing substandard a low PAS. I suspect they tuned it for the Ludi controller and f-ed up the non-ludi M600 in the process. Or they gave me ludi programming by mistake. As noted earlier, on my X1 the torque sensing is awful in PAS 1-2. It's only usable on a steep hill where you are putting constant pressure on the pedals, but even then it will cut out mid cadence unless you are diligent. On flats it's almost unusable. I'd almost rather ride without PAS on flats (vs PAS 1 or 2) because at least you aren't fighting annoying bursts of on and off. I only ride in PAS 3+ on my X1 because they seem to use a different torque sensing recipe (I suspect it's the standard M600 tuning).

            bhaaf one thing I find useful with throttle being tied to PAS level is it makes PAS 1 and 2 (of 5) usable. The problem I have in lower PAS is power cuts out mid cadence and doesn't really become smooth until PAS 3. I can gun throttle in PAS 1 and 2 to prevent the motor from cutting out, and it's not too much power so it's almost like a poor man's cadence sensing. Other than that, for non-ludi throttle is pretty much a "big yawn" as EL34 refers to it. But unlike him I have no plans to take it off as it makes the lower PAS worth something!

            paxtana, that's really strange that you have no access, even your lead tech! Both FLX and cnebikes offer it to customers. Can you at least reach out to bafang and ask them about the latest firmware? I cannot imagine they haven't made any improvement since the release of the motor. Worst case I'll just upgrade my controller when innotrace comes out with one for the M600. Or maybe I'll order a spare motor from cnebikes and get a BESST tool with programming to test for science and rent it out to desperate X1 owners, lol. You guys have come out with the PEEK gear and shorter cranks, I just hope you can works a little more magic to get us the latest and greatest (if it exsits) from a tuning perspective.

            Tell you what, if you want to get a besst from alibaba and hit me up, I can get you a login from Luna-mate. However I can neither promise it will work out to flash with or that it would be usable with a given firmware; different logins will not work with different firmwares, i.e. you can not use an flx firmware without an flx login. And it probably goes without saying but if you end up finding out you do not like the firmware you believe is better, there's no going back. If you are not prepared to potentially totally screw up your ebike then probably best to leave it as is.

          On my non Ludi X1, my only complaint is that 1,2 an 3 of 9 is too powerful.
          I would like to dial back the assist on those 3 levels

            Sounds like to get the most out of this bike you have to learn how to pedal "circles". It's easier with clipless pedals, but modern platforms are secure enough to make it work too - you can't pull up, but you can push forward and back.

            And yet no other eMTB requires clipless pedals for torque sensing to operate smoothly. Sadly it is an endless list of excuses for the M600 tuning. The youtube comparison to the Turbo Levo makes a claim that it's hard to tune because the motor is so powerful. Somewhat comical.

            I'm running flats. I've upgraded the pedals to some nice race face with pins and wear some 510 rubber soul sneakers so they're pretty solid. I'll admit I do like to pedal pretty consistently coming from a cross bike with lots of road and less technical trail riding so maybe it's just a case of my cadence matching up with the way the bike works.

          ​​​​​​​Yep, mine is different it seems than others

          You can see a bunch of my ride info here.
          https://electricbike.com/forum/forum...-other-x1-mods

          I climb a few thousand feet on my rides and some very steep stuff
          I ride on 1-9 most of the day and go up to 40 miles on my X1

          Mine is a very early X1 from 2019

          Comment


            I have been using clipless pedals on all my bikes since the 90's
            The X1 is no exception
            It's just a way more efficient way to pedal a bike
