    Hello, Will a frame with a prefabricated G510 bracket, hold the LUNA Bafang Magnesium Ultra Drive motor (I assume it is yes)? Are all the Luna Bafang Magnesium Ultra Drives fitted with all steel gears, or are there still Nylon gears in some of the motors? Has anyone determined and can you recommend the most all-round,versatile chainring size for the Bagang Ultra 1000W. Thanks.

      Check out the Ultra listing it shows the difference in the bracket. If you are good with welding and other fabrication I am sure you could make it work but it would not be a drop-in replacement.

    (72v 50A battery, 18fet controller, mxus 3000w 4t motor, half-twist 3-speed throttle) Sometime when i twist the throttle from a slow speed or standstill there would be little to no change in power at first and then a surge of power after 2 seconds and when i am riding i would have the throttle twisted at a constant point but the power would die down for a second then come back and then repeat a couple times. all of those problems happened rarely at first then increased in frequency over the past week until the bike stopped work last night. rode it to my friends house only a mile away and it was fine but when i tried to ride it home a couple hours later the bike was unresponsive. I already checked the battery and all the basic connections and they all look good but i'm going to check out the inside of the controller and motor later to make sure I didn't blow anything out but I think the problem is either with the throttle or controller. any suggestions or advice would be great

      For Hall Sensor Throttle and some controller checkout information Go HERE.

      For more in depth troubleshooting, please open a new thread with your problem under "Troubleshooting" As it would be much easier to find. :-) Adding as much detailed information on your parts and pieces as possible.

      Hi - I believe this is the reason the Luna Ashtabula to BSA adapter I mentioned earlier is eccentric. I agree with paxtana - there's not enough thread purchase on the locknut.

      My sympathies that the build has been difficult - but you're getting there. You'll be a pro at it when done.

    I've been having an issue with my Bafang HD crank arm bolt coming loose and pulling out of my bottom bracket. I've tightened it several times only to have it come loose again. I've tried blue lock tight and that didn't seem to help. Normally I would simply replace the bottom bracket and move on with my life, but this might be more in depth. I haven't even had it for a year yet...

      The threads on the crank arm are probably stripped, check to make sure.

      Sometimes the metal on the tapered portion of the cranks can deform. Once this happens the crank will never be solidly on there again, ever, and needs replacement. This can manifest itself as the crank bolt coming loose but it's often more related to the crank itself.

      I would wager if you use an aftermarket crank you will not have further issue with the bolt.

      Thanks for the feedback, what do you think would be a good replacement? I'm looking for something that'll go with a bafang hd.

    Hello everyone. I would like to add the Magic Pie to the front wheel of my wife's Gary Fisher Simple City 8. My question concerns the weight on this front wheel when she carries a full capacity in the front basket. Should I add the Magic Pie to the existing wheel? Or order the better wheel set up being sold?

    I have searched for any topics with "magic pie" and "simple city 8" but haven't found any topics. I'm new here, so maybe I haven't searched correctly.

    Can someone send me a link to the answer, if there is one? If not, can someone give me some advice on which way to go?

    Thanks.

    Mike

      Thanks ncrkd. No experience with building wheels. I'd rather buy the pre-built wheel, I just need to make sure it will be able to handle the weight of a fully loaded front basket.

      I don't think weight bearing would suffer at all.

      A double walled rim seems what is recommended with heavy spokes... But I'm running a rear MP5 on a Huffy single wall rim using the OEM spokes custom hand forged by me and having no problems. My bigger concern would be your installation and using torque arms, especially if that's an aluminum fork. Here is a bit of a debate on the subject...

      Aluminum Front Forks

    I am amazed that this thread is over 130 pages long at this point.
    It's been great chatting with all of you, this thread is easily one of my favorite things about the forum.
    Anyway just wanted to mention that. Hope you all have a great weekend, and for those in usa, happy labor day!

      You are so going to pay for that nice comment! Throttle and pedaling HDs. Nobody's fault, but we consumers are programming around the problem. I got a newer one, problematic, that won't throttle with PAS, but will at setting 0. My newest one won't work like this. I do have it working with PAS disabled, set to 0, but no PAS. I only care if the throttle fails or I want to have a beer in one hand and a joint in the other. Otherwise using the throttle to help pedaling is my preferred method. Attached are the programs, nomad has PAS, Uzzi doesn't.

      You quite rightly closed my thread on this. Just want to see other peoples way around this and share mine. Maybe my solutions are the only ones. Come on fellow posters, be mature about this. We get great help, don't ruin it.

        Have you read AZGuy's research on the topic? Might come in handy, though it would entail removing the potting by hand and messing about with the circuits.

        Thanks, I am one short doing of his mod. These two files represent the best i could do short of using tools and incorporates the information I could sift out of posts so far (Also I hate to touch the controllers becuase I seem to be bad juju when it comes to controllers. I have smoked 3 not even riding them.)

      when do you expect to have more 48V shark battery in stock?

        That should arrive within a week, maybe two at the most. 52v shark will arrive a week later, as will 48v dolphin.
        52v Wolf was just restocked if you prefer. That's what I would go with.

      OK - BSS02 Shut off problem is persisting. Now I'm getting shut downs even at 53v on my 48v shark pack.

      I've bent the cradle pins all the way to make sure there is a good connection.
      I've upgraded to the color display to watch my voltage as I ride. It always reads at least 51v.
      My latest shutdowns are happening even when I have a full charge. It shows 53.5v on the monitor while riding. After shutdown, I check the charge with a multimeter and I'm at 53v. The indicator lights on the battery pack are all green.

      I can usually get the thing to stay on for a ride home after unplugging and plugging the battery pack to the motor several times and turning the system on again. Not sure if this constitutes a power cycle, but something about it gets me home.

      I have three charges on my system and less than 100 miles.

        Inside the battery pack or is this the controller inside the motor?

        Inside the battery pack

      I have a BBS02 with a Lekkie Bling Ring 42. On the back I have an Internal Gear Hub Alfine 8 with Di2 electronic shifters.

      I just installed a single speed chain. The tension is quite tight, so it does not skip at all, but it’s just a little noisy. Is the Bling supposed to be compatible with a single speed chain? Is there a better option for a different chain ring that would be better for a single speed chain? I find that the 10-speed chain breaks a bit too often under load.

        I tried putting a single speed chain on my BBS02 Lekkie (also a 42T) and it didn't fit. It was only then that I saw the writing printed right on the chainring... 7/8 & 9/10/11 speed. I ended up going back to the steel bafang ring.

      I want to buy a sur ron bike, but would only do so with a pedal kit, and i dont see them on your site.

        It's sold out but we will be restocking them next few weeks

      Hey guys,

      I bought the Luna 48 volt Panasonic 17.5 battery pack as well as the Luna 48 volt 3 amp mini charger. I tried charging the pack for the first time but after 12 hours the LED never changed to green and the charger never shut down. Any ideas what's going on? Is this charger not compatible with this pack?

      The battery shows 54 volts so it looks like it fully charged. I checked the adapter cable (barrel style on the pack) and it was fine. I read where the packs should be charged to 100% the first 6 charges so I had the charger set to 100%.

      Thanks

        If you are referring to the cable with the yellow plug on the end of it that is for the gear sensor. You can change the programming sure, check out the programming section on the forum

      Wondering if y'all plan on offering rear rack batteries again, or failing that, maybe recommend someone reputable who does?

        Probably at some point, yes. It will be a long time though.
        A lot of other packs can be mounted on the rear though. That pack was just flatter.

      Any idea when you'll have " BAFANG BBSHD 1000W MID DRIVE KIT" in stock?

        Soon. Give it a couple weeks. We are always re-stocking this motor as soon as it's out of stock

        Next time though keep re-stock questions in this thread, please:

        68mm was just restocked a day or two ago. 120mm should be restocked in the next week or two.
    Working...
