    Hi, trying to order the BBSHD kit but there is no longer an option to choose the 52 v shark battery, only the 52v dolphin. I'd rather have the 52v shark due to size and I assume it would be cheaper buying it as part of the kit instead of separately. Whats the best way to do this? Thanks.

      Sharks are backordered for a few days, sorry. We will have more soon.

    This is listed as a possible tire for the Apex, but I cannot find details on it. What is the size of the tire?
    This question was for the Big Ben tire, which is no longer listed as an option so....never mind.

      When you get the shark batteries back in, will the option to pick it reappear in the BBSHD kit options?

        Jynx. You owe me a beer.

      Curious as to what functions are controlled with which buttons on the new apex bike. What is new in functionality.

        I am looking to r4ebuld my battery pack for my electric cargo bike.

        Here is the current configuration of the batteries the bike came with.

        Aside from batteries, a soldering iron, and solder, what equipment and what kind of batteries do I need to do this job?

        thanks

          Not very plausible project, IMO. Cells are spot welded and soldering them is never recommended.

          Probably worth digging down and finding faulty cells/groups and learning IR testing?

          Maybe scavenge some good cells or cell groups for other smaller battery pack projects but unless you know the approximate age and IR of the current cells blending them with other cells probably won’t be a good outcome. And it may even be a dangerous outcome?

          When I told my electronics technician that I was interested in learning to build my own batteries, he was very discouraging. He was talking about the danger of acid splashing in my face and potential fire hazards. I still want to learn to build batteries, but I will sure do a whole lot of research first.

          I'm not discouraging Dan the Man; I am just relaying what my guru said. After extensive research, the next step would be to get an appropriate spot welder for the task. My buddy just bought one for about $150.

          I just finished my build and the bike works great, but I have one problem. On my Luna 750c Full Color Display I get a message 'error code 21 - speed sensor issue' when I ramp up to speed. What did I do wrong with my buildout? Thanks. Ned

            Something going wrong with the speed sensor - https://electricbike.com/forum/forum...-for-the-bbsxx

            Systems can be ridden without speed sensor input but you might want to disable Auto-OFF feature in dash/display so that the system doesn't shutdown after whatever minutes Auto-OFF is set for.

          Just bought and installed 2 BBSHD kits w 52V bottle batteries and Luna 52V 2.5amp mini ebike chargers. Are both the red light and green light supposed to blink while charging? The mini charger manual says "Led #1 will stay Red..." . Both Batteries on charge show Blinking Red and Green lights when connected and steady Red and Green lights when plugged to power (wall) and not plugged to batteries. Just don't want to f*~k $1000 worth of new batteries. Thanks.

            Please email support@lunacycle.com In the meantime, it's probably OK to leave it clicking/charging. And somewhere above 50V it will likely begin charging normally.

          Hi,
          I just wanted to get some help with all the option when buying a BBSHD motor. Specifically with all the chainrings. I don't know which ones to get or even if I need all...
          There's the chainring, then the chainring adapter, sprockets, faceplates, and then more chainrings when you scroll down lol... I also don't know wh
          Can someone plz help me out with all this?
          I just want a configuration which is fast and powerful and light preferably.
          If it helps, the bike is going to be converting is the 2017 Gravity FSX 2.0 (Is this a good bike for an eBike conversion kit?)

          Sorry if I posted the same thing twice, it didn't show up on my screen

            You'll be working with very minimal space in that bike. I believe the standard Shark Pack just barely fits and will likely need some modifications to the cradle.

            As for chainrings, just ignore that stuff for now and don't get tied up into it. Each ring has it's own specifications and offset, probably just better to go with the default ring and just choose something fancy after you've gauged what kind of chainline you have and how much offset you have to work with

            Because of the presence of the motor taking up space, the point where a chainring would mount onto the motor is pushed out to the right from where a chainring would normally be. Offset is defined as how much distance you are able to bring the sprocket closer towards the frame. This results in a better chainline, less likelihood

          We have a "Luna Little EBike" that we love with a "48v Panasonic GA 10ah battery" and "Luna 48V Advanced 300W Ebike Charger" When I plugged it in to recharge the other day only one red LED came on and it never charged, even after overnight. What should I do?

          Hope this comes in as a new topic and not a reply to an existing one...

          Ok here it is...am I the first to ask this? Are any of the BBSHD and Ultra internal parts interchangeable? Could I make my BBSHD more bulletproof with Ultra parts?

            Nope, sorry.

          Morning all. So today after my commute in to work my Luna Advanced 300w charger decided it was not going to charge.

          Details:
          Over the past couple off weeks I've had to fiddle with the barrel seating to the shark pack to get it to start charging. Somtimes rotating it, sometimes pulling it back out extremely slowly until I notice the charge LED 2 light up red.

          I've spent the last hour or so fiddling with it with no success. know the battery pack is good because I have a second charger at home that works 100% of the time, used it this morning.

          Any troubleshooting tips?

          Here are a link to some pics of the equipment I just took. https://imgur.com/gallery/KdwnV

          Edit: Fuse looks good, currently trying to track down a multimeter at work.

            paxtana:
            Honestly, my advanced charger has lived a pretty cushy existence. I'm lucky enough to have access to a dedicated fire suppressed room at work so it lives there permanently and I bring the battery in after removing it from my bike to charge it in the fire suppressed room. It never hangs from anything. That being said, there is a very feint indentation/collection of dents that has developed on the outside shell of the barrel. The indentations are in the exact same spot all the way around so it forms a line around the entire circumference of the barrel about 1/8" from the tip, I'm not sure if it shows up in the original picture...

            Here's a better picture.


            In comparison, my Standard Luna 2A 52V charger lives in my garage charges the battery while my bike hangs in a bike stand so the cord has to travel upwards and it has been rock solid, no sign of indentations/dings.

            My Advanced charger has been slightly temperamental with barrel position since the get go, but I didn't think much of it until recently in the last two weeks where it has become a dance to get it perfectly adjusted.

            I'd be happy to order a couple one with the normal and one with the prototype.


            EDIT: Adding more detail: Found a multimeter and successfully tested continuity of positive and negative lines of my XT60 male to barrel adapter.

            EDIT #2: After about 5 minutes of using the "rotate and wiggle" technique I got it to charge... just jacked it up to 5 amps so I dont have to sweat on my ride home :)... definitely not a permanent solution, but will get me through today.

            PM has been sent.

          Hello.

          I've been using the BBS02 Model A on my Babboe Curve Cargobike for about 9 months now. The past two days the motor is acting strangely and I believe my controller has moved on to the other side. Display is functioning but no PAS or throttle love. I was wondering if there are any recommended programming settings for a cargo bike on the BBS? It's a 50kg + bike, so pretty heavy to get going. The start has been a little brutal in the past. I have the mighty mini mounted on the unit to minimise heat buildup.

          If this programming is available, could I order it pre-programmed from you guys?

          Appreciate any info on this.


          Kind regards,

          Chris

            You should be able to leave a note in comment box during checkout to have it pre-programmed to your specifications and they'll help you out with that.

            Although I'm not sure what you mean by recommended. Generally we ship all of our motors by default what "we think" is the recommended settings. This can vary from person to person. Here's a link for a comparison of all of the popular settings:

            It probably is the controller but it could also just be something like a phase wire come unplugged. Before replacing I would pull the original controller as shown on our videos and then plug it back it

          I am considering buying a Bafang BBSHD mid bike motor for my older Specialized Rock Hopper. I am confused. Do I have to peddle all the time with this motor like many other mid bike systems. Can I just use the throttle from stop or stop pedaling and let the bike move me?

          Thanks,

            Either or both!

          What is the measurement of 'B' in the attached drawing? What are the Offset measurements of the Luna 42T and 36T Chainrings?

          Thanks!

            B appears to be using a completely arbitrary point for the upper part, I don't see where to put the tape measure to check it for you without knowing exactly where that dotted line is supposed to be. Offset measurements are on the chainwheel KB thread
            Because of the presence of the motor taking up space, the point where a chainring would mount onto the motor is pushed out to the right from where a chainring would normally be. Offset is defined as how much distance you are able to bring the sprocket closer towards the frame. This results in a better chainline, less likelihood

            Thanks Paxtana! The link was useful but it didn't include the Luna 36T - is it the same offset as the 30T?

            Let's forget solving for 'B' in the diagram - what is the measurement from the edge of the BB to the spot on the drive side of the BBSHD where the chain ring sprocket will be?

            I am getting ready to buy the BBHSD package from Luna and I need measurements because this build has not been documented yet. It is a Motobacane Fusion Elite 27.5 Plus Bike with Boost hubs from BD. The Chain-stay sticks out a little different than other 68mm BB bikes and I need to make sure the chain alignment is optimum and the motor does not interfere with the chain stay.

            Thanks!

            36 is the same as the 30t mighty mini. Anything lower than 40-42 is not going to wrap around the secondary housing and it's going to be way less offset.
            If I understand your request correctly it's about 140mm. But all the chains attempt to wrap a bit around the secondary so that number wouldn't tell you much..I would just go with regular bbshd stock ring and go from there once you get a feel for what you need.
        Working...
