Is this a dire situation and should I immediately stop riding? Or can it wait until I have a free weekend to work on it? I was hoping to do maintenance in February. Thanks.
    A "noticable whirring sound" that wasn't there yesterday. Should be enough information. Anyway, found the fix here: https://www.youtube.com/watch?v=3lVRTRFueUU

      I mean, not really..You might get "whirring" from other things as well like a failing clutch, dirt contamination on the secondary gear, or even just something rubbing against the chainring like you might experience if the cover was a bit loose.

      I recall earlier in the year one of our forum members kept hearing a ticking..turned out it was nothing mechanical at all and he had just left the protective sticker on the controller, which started to peel off and was contacting moving parts. Stuff like that can happen, and a single word description of "whirring" is not enough to rule out that sort of thing.

    I live in the UK and bought a BBSHD controller from Luna recently,after fitting it the bike is now down on power by 3 to 400 watts on each power level and seems to max out at 950w on level 9 compared to my other BBSHD bike that maxes out at 1500w .Both controllers are programmed exactly the same .As well as this the green battery icon in the top right hand corner of the screen is showing depletion at nearly a full 52v battery and it has never done that before unless it is nearly empty.

      This is just the original controller, correct? Not the Ludicrous version? Were both controllers tested under the same battery power level too? Check your display settings to make sure no speed limits are set either.

      And when you said they are programmed the same, you checked each one with a programming cable using the flashing software on a PC and you've verified that the amps for both of them are set to 30? And to be clear, this happens under both PAS and throttle only modes, yes? Or does it only happen in PAS 1-9?

    PAS only don`t have throttle,both controllers are programmed with your black box and they are both original controllers set to 30A.Yes both tested with the same battery level.No speed limits are set.

      Do you have the throttle that came with it? I would plug it in to help rule out the PAS as suspect.

    I have a Bafang motor that was running fine and then just seized up. The pedals will not crank at all. The bike only has 1,400 miles on it. The only numbers that I can pull of the motor are CR R209 750. I can not find anything on your website about this part number. I need to know what I need to do to get this motor running again whether it is a core motor replacement or something different. Please help. Thanks

    No don`t have a throttle,never used one.

      Check if the PAS options are also set to the proper % in the programming settings then. Maybe pick up a throttle and see if you get the full 1500watts in PAS 0? That can help rule out if it's just an issue with PAS settings or if the whole controller is having issues.

    Will try to get a throttle and try it ,yes all percentage levels are the same on both controllers.Why is the battery icon on the screen showing depletion at a high battery voltage with the Luna controller,that has never happened on any other bike i have built as they always show full until nearly empty,it isn`t the screen that is faulty because both screens do it with the Luna controller.

      Well one thing should be noted here. The display does not accurately show battery level through the % gauge. None of the displays have ever done this properly or reliably. You should be switching it to voltage in the settings of the display and then using the voltage number to read both batteries to make sure they are equal. There's a voltage chart at this link here:

    Yes i do use voltage not percentage,as an example the voltage will show 56v stationary after a short ride and the green battery icon at the side of it will show slight depletion,this has only ever happened with the Luna bought controller never on any other bike and i have built four BBSHD bikes in the last four years.

      The green battery icon is not accurate with 52v batteries which is what I'm trying to say. It was designed for 48v in mind which is why your previous builds may have been different (assuming they were 48v) You can just ignore it and not factor it into anything. Just focus on the 56v which his about 80% battery or so roughly using this chart here:

      https://electricbike.com/forum/filed...2&d=1521089057

    Why does the battery icon not show full until the battery is nearly empty,only the Luna controller has done this.All the builds have been 52v.

      I don't know where your builds were bought from or what displays you used. As far as I know, it's always been like this.

    When do you guys plan to have more white wolf 680+ frames (med specifically) in stock?

      We can notify you once we get some if you want

    First time ebike builder. I want to make sure I get the right size Bafang HD kit. My bike is a 2008 Rocky Mountain Trailhead. I have the bb already removed. It is 73 mm wide. I believe I should get the 68-73 kit but have read you should go to the next size up? I have included pics.

    Thanks.

      It usually depends how wide the chainstay is and whether the motor interferes with it. It's hard to tell through pictures so you may have to order the 68mm-73mm and then see if it fits without interference, if not, then just return it and go for a size up.

    Thanks for the reply. Ok, so any hints on when you'll be dropping the next 26x3(ish) hard tail? While I'd love to buy the Apollo, it's out of my price range at the moment.

      No hints to give out right now. Sorry :(

    Could the problem be the motor core ?, or would a bad or poor connection between the battery and the controller be the problem,would these cause the loss of power i am having.

      You can check for that stuff physically but without ruling out the throttle only mode, it's practically impossible to say. I mean you did say it only happened when you switched controllers which should rule out everything else but a programming error.

      Maybe email support@lunacycle.com with a video showing us how you're using the BlackBox to program it just so we can verify it's all being used and saved correctly. Sometimes these programs are a bit finicky and you may have to hit the save button more than once.

      Also cannot rule out the possibility of the BlackBox not saving/reading the settings correctly. So maybe pick up a programming cable and do it the manual way? We have a guide for this here:

      https://electricbike.com/forum/forum...shd-mid-drives

      And also, just to be 100% sure, this is not a Ludicrous controller from the Black Friday sale, correct? Just a regular BBSHD controller? Cause if it's Ludicrous, that would be the reason it's happening because you're outputting double the wattage despite what the display says which is just normal behavior.

    No i don`t think it is ludicrous i just ordered a normal one,I will try to get hold of a throttle and try that and will send a vid with how i use the black box.

      Tried a throttle and the max watts is 950 to 1050 fluctuating,the programming is set to max and 30A.That is with a full 52v battery.

        It's not going to pull peak unless you are either lugging it or going uphill, and even then most of the time you will only see it for a short while, such as when accelerating from a dead stop. Check where and how you are testing it

      i have recently purchased a m2s with the ultra wondering about tuning the torque sensor does that work ? how is it done?

        That is outside the scope of this thread and far as I know not possible.
