    grandglaize sure that works. Just did a video on it last week, see here.


    You don't need wiring on the cradle since cradle is bypassed. You can still mount to it but wiring would go directly to controller from case.

    The wiring in the case is 12-14awg and the xt90 wiring is 8-10awg. In theory you can use a step down splice from these. In practice due to the wires on the xt90 being a bit oversized you need something like 8awg unless you trim a few of the xt90 wiring strands to make it fit. You'll see what I mean when you work on it.

    Easiest way is probably just a straight 8awg heat shrink butt splice and crimp the shit out of it to make it work even on the significantly smaller side though I have not tried it yet. No 8awg to 12-14awg stepdown splice exists unfortunately.

    I have black programming box I bought last year and just used for the first time. When I change a value in any window, it changes one number. If I change another number the first number reverts to its previous value. Is there a firmware upgrade or any known problems like this? It is usable if I use pre programmed profiles, but I cannot write my own.

      Never heard of that happening before.

    What are the differences between:

    and

    https://lunacycle.com/BAFANG-750w-ge...r-front-wheel/

    ??

    Also, do you have a datasheet (including dimensions, rpm, etc) for each?

    Thanks!

      Maybe he wants the "flange diameter" because he is calculating spoke length.

      yes, sorry, I of course meant flange diameter.

      We don't have that info nor would we recommend going off of any measurements other than your own when getting the numbers to enter into a spoke calculator. Specs can vary across models, across production runs, and across years and documentation can not be depended on to stay in date.
      A bike shop can take the measurements and get you the right spokes if you want. My local bike shop measures it for free if I order the spokes through them.

    I built up a bike with a Xiongda 48V 2 speed hub for a friend with it and sent her on her way. Within 5km the motor cut out, she killed the battery power and turned it back on and off she went again for a while. Then it happened again & again. I thought perhaps she was having a BMS issue with it cutting power but the display was staying on. If she cycles the power to the system with the handle bar switch it resets. Any ideas?

      And you could try using the built in diagnostics in the display. Also check whether the motor is getting hot and check whether the controller is getting hot. If so she might want to try downshifting.

      If the display is staying on you might also consider that the ebrake connectors are shorting against something, or they have been cut or severed or smashed in such a way that internally they are shorting. For example as a result of over tightening the wires to the frame using a hoseclamp

    Just curious if Luna is expecting to offer 8t Mac hub motors built into 700c wheels at any point?

      Probably next year.

    ok new here and not sure where to get the best answer. i just received my wolf battery and charged to to 100% using the Luna smart charger. plugged it into my 1000w BBSHD and the display powers up but nothing else happens. throttle does nothing and pedals spin but motor never engages. the whole set up is new and ii's my first build so i may be missing something obvious, like an big ON switch or something? also on a DPC 18 display where is the indicator for the brake cut out appear. i have waved the small magnet in front of the hyd brake sensor but nothing changes in the display

    thanks

    f

    ok since the display didn't indicate i had the brake sensor functioning i thought it wasn't. i disconnected both sensor wires and the motor runs with the throttle. so now i just need to know where the display shows the brakes so i can set the magnet to sensor distance properly

      The display shows ebrakes activation as this indicator: (!)

      Probably easier just to be hitting the throttle and seeing how far you can pull it away before it cuts.

    not on this display. i got the magnets set but there is no indication at all on the display

      You appear to be out of the Mighty Mini 30q 52v packs. Do you know when they will be back ????? Thanks......yes, I entered my email on the site, just wanting to know if it is a few days or a longer period.

      Thanks in advance,

        Probably more like weeks rather than days.

      On my most recent BBSDH build, throttle response is smooth, unless I am pedaling in any PAS then there is no throttle until about halfway through throttle range and then it comes on wheelie strong.
      Is there a programming way around this? I just watched an 80 year old guy pop a wheelie and go down at 10 mph on a hill trying to get a boost with his throttle.

        Even in PAS 0 I can't pedal while using throttle. Is there a way to disable the throttle outside of PAS 0?

        There is a way to disable PAS completely if that works.
        https://electricbike.com/forum/forum...tting-pas-wire

        Curiously this does allow full use of pedaling while throttling.

        Nice to have the option. Thanks Paxtana.

      I am currently trying to clean the luna lander fork with the optional rebound damper. I have already noticed that after only a few rides the stanchion that holds the damper is showing significant wear through the black anodized coating and I am guessing the stanchion may not be properly lubricated as the other stanchion still looks good as new. I cannot however figure out how to remove the lowers. The bolt on the air-spring side came off no problem, but I can't figure out how to release the damper side. Any thoughts?

        My new DCP-18 display reading 45 volts with a fully charged 52 V battery. Same problem with 2 different Shark batteries, both testing > 54 V on DPC-14 display. Any known issues with these displays?

          There was an issue on the older DPC14, it would only read 56.4. I do not recall seeing anything about dpc18 having a similar issue.

          Turns out display works fine on other bike. Tracked it down to low voltage coming from controller. Bike works OK. Anyone think of a reason controller voltage would be low?

        I see on the page for the Lekkie Bling Ring that "This chainring will NOT work with the BBSHD." However, there is no explanation for why it won't work with a BBSHD. I was thinking about getting a 42T chain ring, but obviously want it to work in conjuction with my BBSHD.

        Many thanks for any guidance you can offer.

          Are you looking at the BBS02 version of it? Cause that could probably be why it says that. The BBS02 uses different bolt placement pattern than the BBSHD.

          You were looking at the bbs02 lekkie not the bbshd one. Click this link. https://lunacycle.com/lekkie-bbshd-b...ing-chainring/

          Bbs02 rings do not work on bbshd motors because the they use a different BCD.

            Yup, Peter's right. Investing in a kit is the way to start out. Start becoming interested, make it a hobby in your life until everyone knows you as that "Electric Bike Guy" then start applying at random shops.

            Which kit to recommend? Where should you buy them from? You're really starting from scratch huh. These are definitely things that I had already figured out before I started working here so you wanna make sure you've read enough and researched enough. Don't just take our word for it. Figure it out yourself. Weigh out the options. Start reading the forums to see what's popular vs what's not and what people are talking about. Read this thread if you have to and see how we answer our questions. This took me about half a year to do.

            If you wanna get a job doing this, a lot of it is going to have to be learning out of your own self interest instead of looking for answers to general questions. Although it never hurts to ask, but it's always important to search yourself to get a better outline of the whole situation. Make a name for yourself on the forums.

            PS, the BBSHD/BBS02 kits are one of the most popular & recommended kits right now. However your local shop may not deal with them specifically. That's something you should find out before-hand. They may also deal in pre-built bikes only which usually have proprietary components with minimal troubleshooting involved. Usually you need less of an electrical background in that case and more of a general sales background with some light bicycle knowledge thrown in

            When I was going to United Bicycle Institute in Ashland, OR, one of my fellow students got a job offer from an ebike shop in Portland on a Sunday afternoon. They hired him over the phone and he started the next day. We were all very surprised that he didn't come back for the next class, but I guess he wanted to start his career. So maybe you could go to a bike school. There are also bike schools in Colorado and North Carolina.

            There were countless Canadians in the school, by the way.

            You will also want to learn how to solder and crimp electrical connectors.

            As you Google and read, you will see what else you need to learn (e.g. how to install a headset, install a crankset, set up a derailleur, use a multimeter, etc.). You can learn all of these things on YouTube..for free! A good start on YouTube is the Basic Electronics tutorials by mjlorton https://www.youtube.com/watch?v=0HXE...A1AD995AB64055 and Jim Pytel https://www.youtube.com/watch?v=Do7V...zFXQ2H-zXQFMlI

          I bought BBS02 kits and BBSHD mid drive kits from Luna and a couple used hardtail bikes from the local bike rental shop at the end of the summer. Luna is a great vendor, prices are right and they have stood behind me all the way. My 16 year old son has a small business converting bikes in my garage. Be patient at first, there are delays when you don't have the right tool or part, but soon you will accumulate crank pullers, bottom bracket removers, a good set of Allen wrenches and box wrenches, a decent bike stand, and you move on to conventional bike tools when you have to move and cover brake or derailleur cables to make room for motor, add disc brakes, upgrade forks, etc. It helps to have a friendly local bike shop who will remove donor bottom bracket if you don't want to invest in single use tools.
