    Hey guys

    Thanks for the great support and product so far. I'm having a lot of fun on the fastest e-bike in Stuttgart. Now someone stole my chrager so I need to place a new order with Luna and got to thinking about another issue that I want to solve.


    I'm riding with BBSHD as a commute in the big hills near Stuttgart. I try for max speed for the whole journey in terms of peddaling and setting on the BBSHD.


    I am running the Shimano XT with 10 speed rear mech. I am a little worried that the chain may break or at least get quickly worn. With the forces involved this could be dangerous? Has anyone had a chain snap? What was the result?


    Did anyone try the Luna single speed chain? Is it thicker / more robust? I am thinking of changing to something less fine than the Shimano XT.


    Thanks


    Richard

      Not sure what you mean by Luna Chain? You mean our KMC chain? KMC chains are usually the way to go. Yes, chain wear/cassette wear is definitely a thing. You can heavily reduce this by only shifting manually with your legs and not while the motor is under load.

      Hi Richard, the thinner the chain the weaker it is for sure, this is just a fundamental fact. So a 10spd chain is weaker than 7spd or single speed sure.

      The unfortunate thing is that the drivetrain companies do not yet put their best tech into drivetrains meant for lower number of sprockets. No clutched derailers, no fancy sprockets with latest designs to prevent skipping, etc.

      Smooth shifting with a middrive is also important just like a big chain to prevent wear, but which one is more important who knows. Both approaches have pros and cons.

      Check your chain sometimes with a chain wear tool and you'll probably be fine. Especially check it if it is skipping.

      You don't want single speed chain unless you have a plan for using it. You definitely don't want a single speed drivetrain.

    So it wasn't the nylon gear or pinion gear. The gear on the rotor sheared right off. Is this covered in warranty some how?

      Need to know if it's hd or 02 and how long you had it.

    It's hd and purchased it on May 20 this year

      Yeah send us an email with your order number

    I bought the https://lunacycle.com/bafang-half-tw...le-right-side/ and for the life of me I can't figure out how to secure the throttle (right) side. The left side goes on tight, but the right side just slides on, spins and would slide off if I tipped the bike. Is there some sort of locking mechanism I'm missing? Thank you.

      Maybe use a bit of silicone tape on the bar before sliding it over top?

      I was hoping I was missing something obvious. If that's not the case I'll just grab one of my thumb throttles and throw this in the used bike parts pile LOL.

      I don't think we would have any way of knowing that it is missing something obvious..hell it could be something super simple like you got thinner bars than typical. You're welcome to send it back if you don't want it, can probably at least hook you up with store credit..

    I’m wondering if anybody can tell me what these abbreviations are on any brushless controller? That being said which ones I.e. hall, power, throttle etc. absolutely have to be connected in order for the brushless controller to work? It may seem A bit simplified but seeing that the abbreviations are universal I think anyone with a good electrical knowledge of brushless circuitry can hopefully answer this for me

      What happened to my BBSHD. It's going slow... like 5-10 mph slower... and shows more watts. I greased inside but no luck. What else should I check up on? it used to go 22 mph on P.A.S. 4.. now it goes 20 mph and couldn't go uphill and watts reads 300-400's instead of 200-350's. Is it my controller or what?

        I take it you already gave the rest of your drivetrain a tune-up?
        And that you did not change the programming or the chainring or the cassette? And are following the same shifting procedures? And that you have the same load?

        There's a lot of things that are isolated to a particular bike than anything else and not really something I can speculate on.

        Are you using this commercially? If so all bets are off, could be anything, that's a whole other level of wear compared to recreational use.

        Check your copper windings on the motor core side to make sure they're not toast, or close to it.

        What I did is replace the rear wheel with new Shimano XT hub because the last wheel had bad bearings which were slowing it down. I did not change the programming or anything. Same chainring and same cassette etc. It was a really hot day and I rode all day yesterday, but today was so slow and I tested both wheels and they are true and butter smooth. It was so perfect yesterday and now it's not even close. Maybe something overheated or something, I have not opened the other side of the motor beside the greasing area.

      Hi my name is Will, I am currently trying to restore an old A2B Ebike made by Ultramotor.
      the bike is from 2009 or so
      500W hub motor
      i replaced the original battery pack (which blew out) with a 36V, 10 A*hr battery pack from dakota lithium.
      bike worked great until i started to pull my kids in a trailer up hill......then i let the smoke out of the controller.
      i need to get a controller that will work with this setup.
      preferably one that can handle high torque low speed applications.

      any suggestions?

      my background is Mechanical Engineering and i have worked with very high end controllers and motors in the past.
      Im just getting into the modern commercial e-bike scene so i need a little orientation.

      feel free to hit me up with technical questions though

      Kind Regards,

        Have you considered swapping it out with a kit? There's controllers you can put on it for sure but if you're pulling a lot of current you may run into problems with overcurrent issue on the bms as well as potentially smoking the motor. If none of that matters and you just want a high power controller and have no problem rewiring the halls sensor wiring and the other wiring which definitely is not going to match the original, something like this MAY work..but it would not be simple or straightforward at all https://lunacycle.com/motors-and-kit...ke-controller/

        Probably the bms in that little battery is not rated for 40A nor is the cells so would probably need a couple in parallel or a bigger battery, then if it's a DD hub might need to mod it to prevent overheating etc.

      Can I use a 36V(nominal) battery with the BBS02 motor and controller?

        Not unless it's a specific BBS02 that's made for 36v batteries. If it's just a regular BBS02 like the ones LunaCycle sells, then unfortunately, no.

      Does the "Mac Motor/ ASI High Performance Hub Kit, 6T front hub motor" have disc brake mounts? If laced into a 20" rim is it caliper friendly? I have a steel front fork with v brakes. Will it work?

        All the hubmotors have disc brake mounts.

        If you want to use V brakes that's really more dependent on what sort of wheel the forks are for and what wheel you have the motor laced into.
        If you are asking if you can put disc brakes on a fork that has no mount for the caliper you may need to swap out the fork for one that has iso or post mount.

      I want Luna to lace the wheel into one of its Alex 20" rims. I'm new to this. The front wheel is laced dished so that the rim is centered, even though one isn't using the disc? Sorry for the stupid question. I just want to make sure before I drop the $500.

        It is dished yes, though we can not guarantee it will be perfect for your bike and may need to be slightly adjusted depending on the frame used. Dish does not affect where the disc brake is located though. It moves the rim relative to the hub but does not move the rotor relative to the hub.

      I would love to know what the abbreviations are on the back of any brushless controller. They all seem to be universal, that being said I would love to know which of these abbreviations have to be connected in order for it to work. I will include two different photographs below showing two controllers and the abbreviations I’m referring to. To me it seems like any E bike enthusiast would want to be familiar with these particulars. So so many ​​​​​ gracious thanks

ID:	72297 Can anyone tell me what the abbreviations are on the back of any brushless controller? Admittedly my experience is limited Being that I only have three different controllers yetThese abbreviations of which I speak seem to be universal. If somebody out there could please tell me what these abbreviations stand for or at least what they coincide with I.e. hall, throttle, etc. and in doing so tell me which of these absolutely without a doubt have to be connected in order for the controller to work. Or for that matter which of these abbreviations and/or The wires attached to them can be ignored and the controller still work. I have included a picture highlighting The abbreviations of which I speak. Thank you so much

          May want to start a new thread for that

        Greetings My wires have slipped back in my cyclone 40Amp Standard controller. I am looking for a schematic for the controller PCB to ensure I am connecting the correct wires when I install this? Thank you!!

          I just installed a new X controller on Sur Ron and headlight and display flashes but will not work. Double checked from your install video and all is in correct and anti tip sensor is also in correct. The brake cutoffs were removed...could that be it or what do you advise? The bike worked great with stock controller and brake cutoffs removed prior.

          Hello,
          I had a cart with the mac motor and a battery that I had up in a tab yesterday and when I went back today it seems there are no battery options to add to the kit anymore? Was wondering if you are just out of stock or what may have changed from yesterday?

            I don't know what battery you were looking at but likely it was either not in stock or just sold out. We just changed a setting so out of stock options are hidden instead of just greyed out as it's not super clear that greyed out options are unavailable until you try adding it to cart.
        Working...
