    So...Pondering upgrades for the BBSHD...My current gearing is a 30T mini with 11-36 in the rear. The bike will climb anything but thinking it could go faster on the flats now that I've gotten used to it. Full throttle is 19 mph and it has off road programing. Dont get me wrong Im not a speed freak but you know how it is got to mess with it as it's working fine as is....

    So I had been pondering on the 36 tooth which if i went with I'm thinking Id basically gain a high gear and lose a low gear from my current setting.

    But today I look and I see now there is a 40T with the same off set as the 30T am I correct in thinking it would feel like losing 3 low gears and gaining 3 high ones? Not literally but in a sense?

    Thinking to keep my low gear climbing ability Id have to have the LBS fit the 11-46 10 speed Sunrace cassette I've been sitting on, which would mean a new derailleur and chain???

    not sure on this could be a winter project. But need some verification I'm thinking correctly on how this will work.

      Not sure what you mean by gaining/losing gears? Are you using limit screws on the derailer to keep them out of these gears or are you referring to something else?

      If you already have a mini chainring then yeah I would say just about any chainring will work, though you might need chainring spacers if the ring you go with has significantly more offset.

      Yes if you change out the cassette or derailer etc for another speed you probably need to have the other stuff match that speed.

    Hi i am interested in purchasing a Bafang BBSHD hot rod kit. I am in Italy.
    BB size 68mm.
    Regarding the battery I am finding the cut-out for the V2 Wolf Pack just about fits the downtube but with little/no room to spare.
    How much room should I allow for the cradle and space for attaching/removing the battery?
    The bike is a Cannondale Rush (frame size Large), any experience with this frame (specs attached)? thanks

      Not a lot of clearance is needed compared to typical hardcase batteries since it is removed by tilting the battery to the side rather than sliding it up. That said, I would probably take the printout and ensure it matches the measurements on the documentation for this battery, as sometimes when you print a pdf it can print with a different paper size selected and make it seem bigger or smaller than it actually is. Given how far it would be shipped you will want to be sure that your mockup is correct. The mockup accounts for the added height of the mount.

    Understood, thanks will triple check measurements!

      Do I need a narrow or wide chain for the BBSHD with stock chainring?

        The stock ring will work with just about any chain. Not well mind you, as it is not a narrow/wide chainring, i.e. every tooth is exactly the same rather than alternating between narrow and wide teeth as you can see on something like the eclipse ring. See below for how the teeth width changes on aftermarket rings

        Generally speaking, for any install you want the widest chain possible. Not because smaller won't fit stock (though you can't go thinner than 10spd on aftermarket rings you can go thinner with stock), but because the thinner the chain the more fragile it is, which means it will stretch and wear out faster.



      After a 100 miles of riding, my 13.5ah battery charges to 56.6 on the charger, while the display on the bike reads 56.1. Is this normal or a sign of misuse?

        Bike displays are not usually the most accurate with voltage readings. Do you have a multimeter? That's what I would use. If it's a luna charger (one of the blue ones) you can adjust the cc/cv so it tops our more around 58.8 if you like (disregard if you are saying you have it on something like a 90% charge setting)

      Are there any chain guards available for four season ludicrous ebike? I’m tearing up all my pants!

        You'd have to custom make one. Personally I just wear skinny/slim jeans or shorts.

        I wear a leg strap that you wrap around your pants.

      Hi all,

      One quick question after having a hell of a time soldering the XT-90 pots... Does the Luna Direwolf have any wire shorting protection over the XT-90?

      Thanks.

        Yes, the BMS will go into protective shutdown. Typically you would reset it by plugging into the charger.

        Amazing, happy to know I won't go up in flames!

      Looking to purchase BBSHD 1000w controller. Website says to choose version a or b, yet the website does not have this as an option to select or toggle. How can I get one on order?

        It sold out and option is autohidden until restock. Might be a month.

      Hi,
      What are the costs associated with maintaining and owning an e-bike, and how often should I expect breakdowns? In that case, what parts would need replacement the most? Additionally, is there any preventative maintenance that can be done to minimize the risk of breakdowns, and how effective would it be?

        Kind of a broad question.. Depends on the type of ebike, the type of motor, how it is being ridden, maintained, and stored. I would not expect a lot of breakdowns if you are treating the bike with recommended guidelines on stuff like maintenance and preventative stuff, but sometimes shit happens. Two most common parts I see break are the controller and the charger, and it would be good to have backups of both on hand if possible. Dielectric grease on contacts can be good for prevention if using around water https://electricbike.com/forum/forum...bshd-and-bbs02

      Another Q.
      I am trying to make a satiator profile for the 52V Luna Dire Wolf, and the profile maker asks for lead and tab resistance. I see the Resistance of the MJ-1 is listed as <= 40 mOhm using 1000Hz test, but was wondering if Luna had a more accurate number (ie including Tabs and wiring). Thanks.

        Sorry we do not have that info.

      Hi, I WOULD LIKE TO ORDER Luna Charger 52V Advanced 300W Ebike Charger.. to charge JUICED Hyperfat 1100. However, I don’t seee an XLR type connector adapter to order as well , since battery pack for Hyper.fat uses XLR female input.

        You'll have to source XLR connectors by themselves and then modify the chargers connectors with it.

      I have a BBSHD, Luna wolf V2 and luna advanced 300W charger, all brand new.. My battery charged up OK the first time. After my first ride the battery was at ~60%. When I plugged in the charger to the wall it showed displays of 58.7V and 0.00A. When I plugged it into the battery nothing happened. No fan, no change in displays. I had the charger set for 2A and 100%. I tried several times to start over with no luck. Then I measured the output from the charger with a multimeter. Confirmed it to be 58.7V. Then I measured the battery voltage at the charging connector at ~51V. It acted like the charger was not seeing enough of a load from the battery to start it.
      After several more tries of resetting switches and plugging/unplugging, the charger started, clicked on and off a couple of times within a few seconds and then went off again. I got this to happen several times and then it finally started up and stayed running until the battery was fully charged.

      I just tried to charge the battery again after my second ride and with the battery at ~50%. Same problem. Got the on/off thing one time. Other than that nothing.

      I did some additional testing this morning. I set up a test of the charger as your blog showed with a light bulb. The charger started up properly and lighted the bulb. Next I soldered wires to the extra connector that came with the charger. This allowed me to monitor the voltage at the battery input while the charger was plugged in. The battery voltage at the charging port was 48V without the charger connected. Then I connected the charger and the voltage went up to 58.7V but still no fan, no current on the charger display and the charger LED stays green.

      I am going to be out of town starting tonight for about a week. If I need to return something I want to get that started before I leave so please respond ASAP.
      Thanks, Dave Strohm

        Please contact email support for this. This cannot be solved here.
        Also provide the order# in the email.

      Any chance of getting a Luna Wolf battery, WITHOUT the outer shell and the mount system? My use on my Montague folder would not need either. I really like the fully potted feature, and as this is for my airplane, weight is a big deal, and like my current 11.5 AH Panasonic pack, I have a custom made bag that comes off and on when folding the bike.

        Those are integral to the battery. Can't pot it without something to pour the potting into. Spose you could grind the rails off the bottom to lose a few grams, if you wanted.

      I am in the process of electrifying a Mongoose cargo bike and I want to put a BBSHD on it. I have two Luna HDs on other bikes and I'm aware of the throttle/PAS override issue that was such a big source of complaint a while back. Was due to a firmware change at Bafang. Is that still an issue? I have heard on FEB that Luna has it identified and eliminated. I've also heard you need to ask for the patch at checkout time. Both of these things are internet posts so I thought I would come here and ask before making the buy. Whats the scoop?

        That got fixed. You do not need to ask for it to be applied, all of the motors sold by Luna come with it now

        Beautiful. Thanks. On my way to the shopping cart now.

      My Luna shark battery won't seem to charge. When I plug in the charger the charger makes a clicking noise and the red and green lights start to slowly flicker with the clicking sound. It's similar to the video linked here.

        That's slow charging until it reaches >50v. An adapter should have been included that prevents that. Email us if you need another.
