    Hi guys I have a question regarding the x1 looking to purchase one but recently saw a video on YouTube where someone installed a 40 tooth gear up front and said the assist is limited to 25mph and stops working after that. Is this Infact true? Even for the Ludi version?

      There is nothing on the listing regarding the top speed for this motor from what I can see. It is only a 48v battery so naturally it is going to be limited in top speed as is with the limitation of voltage. This is an Enduro bike that was designed for trail use and not high speed commuting. Once you start going over 25mph on an E-bike like this, things start becoming unreliable and components start failing. Ideally speaking you would want to use a hardtail bike for high speed riding rather than a full suspension.

      Thanks a lot!

    Luna and friends, I'm running into full power failure when peddling. I'll attach some photo's below, but what I'm experiencing is some slippage when peddling, like it's catching and then releasing the motor intermittently, with occasional full shut off. This happens about 50% of the time. The unit and initial install was flawless, everything worked, not cut out etc.

    I've checked all plugs, zip ties and nothing seems overly tight, pinched etc!

    What should I be checking in a process to go through troubleshooting...?

    I checked the mag sensor, tire pressure to make sure they were aligned. Gear shift sensor moves etc (cable moves freely). It's concerning since this was $1500 kit, and less than a year is cutting out, which is essentially plug and play. Looking for some help to see if it's something simple or needs further testing with volt meters etc.

      Error memory shows error 4 throttle error. Was this an issue from some earlier time or have you recently seen error 4? If so it could be the throttle or the wiring harness it's plugged into.

      This guide is for a dead unit but is still a good guide for step by step.

      ok so looking over the directions, I think I've reduced it down to the use of PAS and or the shift controller cut off. I unplugged the shift controller cut off, went around the neighborhood with just throttle, no issues. Kick up the PAS to 3 and move around and the power almost studders along with the display. turn PAS back to 0 and only use throttle, no issue.

      Is this related to the error code in the images above? What would be next steps knowing that PAS settings are effecting the power?

      If unplugging the gear sensor fixes the issue then the issue is the gear sensor, probably how it was installed. there is some information in the documentation in the knowledge base on this forum regarding how to properly install that, and how to troubleshoot it so you might want to check that out

    Luna wolf pack battery questions


    My Shark pack charging port quit working. This led me to buy a new Luna Wolfpack 52 V battery And I have a few questions about getting it working. I have low level skills with batteries.
    1. Is there any sort of manual beyond The battery documentation linked on the website?
    2. There are four ports on the battery: 2 XT 90s and 2 XT 60s. Which ones are for charging the battery and which ones power the motor?
    3. The battery kit came with a pigtail XT90 connector. The current BBHSD motor has an older connector pictured below. Do I need to solder the XT 90 onto the Motor?
    4. I have An advanced Luna charger that now has an XT 60 connector on the end of it. Which is not compatible in terms of male/female with the new battery. I assume I simply have to solder on The correct type of XT 60 or XT 90 connector. Or is there an adapter that I can simply plug-in to the existing xt60 connector to make it compatible with the new battery. Thanks for any advice or other ideas. See pics attached.

      The xt60s are for charging.
      There is a good amount of additional documentation on the knowledge base
      https://electricbike.com/forum/forum...-base/chargers

      Ideally you would cut and solder, yes. There is however an adapter if you prefer
      https://lunacycle.com/batteries/conn...ole-connector/

      Looks like the charger you have is one of the older ones if it has that gender xt60 on it, we have not made it like that for couple years. Yes you probably want to cut off that xt60 and solder the correct one on. You could also crimp it or use solder sleeves available in the connectors section. I imagine that if you google around you could probably also find an xt60 male to xt60 female adapter as well.

    soo I am installing my bbshd kit on a specialized Pitch. I ordered the normal bbshd, and honestly I used the spacer that is maybe 2mm wide and it gave me good spacing for the motor from the chainstay. I have two questions, first is it okay for me to route some of my wires inbetween the motor and the frame in the space between the chainstay and the motor? Seems it would be fine and it really leaves my wireing clean.
    2: I ordered the 42 tooth eclipse sprocket. it clears the chainstay but only by maybe the thickness of a creditcard. I am thinking of using one of the sprocket spacers, or am I better spacing the motor slightly more? To me the sprockt spacer makes more sunse as I will still be able to run both the main nut and the locking nut while I might be able to run only the main nut if I space the motor more? Last what is the yellow connector comming off the motor directly? For the sift sensor?

      If you mean routing it like this I would NOT recommend it


      If the Eclipse clears the chainstay even a little bit then it's fine and you don't want to space it our further.

      The yellow connector on the controller is indeed for shift sensor.

    how tight do I need the main lock nut? I have it tight but if I try I feel I can still rotate the motor slightly

      If you can rotate the motor then it's not tight enough. Bafang recommends the steel nut be fastened at 50 N.m

      If you don't have a torque wrench and a bbsxx socket set just keep in mind that's basically as tight as you can get it. I usually use a breaker bar to get it that tight.

    I will have to get a tool for it all I have is the wrench you sold me

      The wrench is fine most of the time. Depending on what you have handy you can also make a breaker bar in use with it, like big pvc pipe for example.

      Even if you don't have a wrench you can tighten it. Flat blade screwdriver with a hammer, hold the screwdriver point against the notch on the steel nut, then tap it to rotate the nut circular direction. I got a video here about how to do that with a different lockring, same concept though. https://youtu.be/ASqdUmNaKrg?t=174

    If I wanted to buy a socket to tighten th nut, is there one? What is it called?

    Comment


      Ok, I found it on your site but you are out of stock, so I searched and got a set from empowered cycle. Am I safe to ride it at least up and down the street a couple of times to test it then when the wrench arrives I will retighten?

        Yeah they been sold out for several months, damn shame about that, hard to find good welders in los angeles. Yeah you're fine to ride it if it's a little loose, worst case scenario it flexes upward. Take care that you have enough flex in your cable management so it doesn't rip anything out if it does flex like that.

        We also sell special mounts like bsb-1 and bsbf-1 that eliminate the need for those lockrings to be tightened entirely. Might be something worth considering if after you get the tool you are still having issue

      Hi guys another question regarding the X1 bike with the Ludi option. Are we able to turn the ludi option off with a screwdriver and adjust between different power settings? And by that I dont mean different assist settings.

        Nope sorry, you would need a whole new controller/motor combo to do that. In fact each controller has to be specially tuned specific for that motor, it's a real PITA

      I actually bought the metal mount "just in case" but honestly it is ugly, I guess i could paint it black, but I will only use it if I end up needing it. if I do I will probably not use the hose clamp but instead I will drill two holes in my seat post tube and screw it to it.

        On another front. your Luna fixed stealth bike. I know the batteries are in the downtube, but is the pack removable for charging or so it can be replaced if the batteries go bad?

        Comment


          The bsb-1? Yeah I suppose it's not as attractive as a lockring but that lockring is always going to be a friction fit. It is never going to truly be as rigid as the alternate mounts. Will stock be good enough? Probably, if you get it tight enough. But there are definitely areas where the other mounts can be super useful.

          Whether that is your bike or not, I can't say as I have not even seen the thing. But it is worth bearing in mind if you continue to have issues with the motor flexing.

          Bsb-1 doesn't necessarily have to look bad though. This is just from some random matte spraypaint and a sharpie, nothing fancy

            Hello, question to Luna, any idea when you'll have the sur ron spare motors back in stock?

            Comment


              if I do not want to run a throttle can I just dissconect the throttle plug then use just pedal assist?

                On bbsxx? Sure no problem

              Hey guys, appreciate the help in advance. I was planning on building/converting a bike for a long time, then got offered a great deal from a friend on one he put together. I ran it for a year now no problems, but recently had troubles with throttle/pas and finally got an error code 08. I'm moving very soon so my tool shop is a little limited, so my plan was to just get a new motor core and and work on repairing/replacing the hall sensors or board later so I can start riding asap. I realized I didn't get enough documentation from my friend, who is a little remote and out of touch at the moment. What is the best way to verify the drive size I have and need? most of the advice is geared towards purchasing a new one, just want to verify I'm getting the right gear. Can post pics or measurements if needed. Thanks!

                There is a label on the bottom of the motor showing what size it is
            Working...
