Hello ebike people I first replied to Luna by my original "Order Shipped" email and got a auto reply with the
case # 133881 I waited a full business day and thought I might of done this wrong so today I logged
in to Luna and filled a Trouble Ticket form and received a email with a case # 134127 . I now see that
either way it delivers the same reply. I did "Not Intend" duplicate cases and from the case #'s I assume
you guys got slammed with about 250 emails in a day or 2 ,,, Sorry!!!

Below in quotes is a copy of my Trouble Ticket case #134127

Soon after I put this Shark 17.5ah battery in use on a Wilderness Energy brushless wheel , controller and thumb throttle.
I experienced brief cutouts and thought it was my controller or throttle, but this problem has gotten worse.
Yesterday my wheel cut out and did not come back as usual. I tapped the battery and the power came back so
I believe the battery pack is the problem.

I noted when the battery cutout, the on-board led charge indicator showed only red dead then after I tapped
the pack she went back to all green led's. The cutouts happen when I hit bumps in the road consequently a bump
revives it. I was able to do 14 miles yesterday only because the battery revives and cuts out upon being
shaken as if a loose connection exist inside the pack. I doubt it is the connection to the cradle, I cleaned and adjusted
it anyway but I do not believe the led indicator circuit goes beyond the pack itself.

After reading a few pages here I see that the BMS may be plugged in and may be a source to my problem but
the pack "Shenzhen" has a do not tamper seal that if broken I believe voids any implied warrantee
"if I do have a warrantee" See pic of my build and Please advise my next move.

Thank You Kindly,
George

:) wired to tight no slack created an intermittent disconnect,,, see pics before and after...

Thanks!!!

[paxtana]

Opening it and checking the bms plug is a smart move, it's not going to void our support policies

[texxs]

I have a Mongoose fat bike (Same frame as the one Luna Cycle used to sell see attached image), It has a mini cyclone. My bottom bracket is making an awful creaking, I'm thinking I need to replace it before it dies. Which size do I need?

[paxtana]

Would recommend to check out the cyclone knowledge base for measurement advice if needed

sur ron x controller intermittent power cut off have to turn off key and turn back on to ride it was all good for 50 miles now it shuts off and you have no power display is good shut off key turn back on and then it does it again and again

Sounds like a poor connection causing an intermittent open circuit. Did you check all of the connections? I had a loose wire cause this issue this once. Check all of the electrical connectors in that circuit or bypass the key switch.

[grayghost]

The display has full power and the micro breaks work fine. I live in Boston, MA. I’ve taken it to 2 bike shops but they won’t work on a throttle ebike.

[ncmired]

By "micro breaks" do you mean the bike's brakes, as in the handlebar brake handles work and the bike stops? What Fred was referring to is that your bike likely has little electrical switches on the handlebar brake handles, either of which, if "on" (in error), will prevent the motor/throttle from working.

Barring finding a local, handy-person tinkerer, I'd guess you'll need to ask more bike shops. I don't know the Mass ebike laws, but via a quick web search I don't see that throttle e-bikes are illegal in your state.

[Tommycat]

An easy check of the brake switches is to just disconnect both of their connectors from the harness and then try it... Up to checking the throttle?
Grab your wiring diagram and...
Take a look here...

[ncmired]

Tommycat, I'm guessing for his bike (see https://electricbike.com/forum/forum...1837#post71837) the brake cutoff connectors are close to the hub motor controller, and probably buried inside the frame main beam.

ASI BAC 800. Can this be used with the bafang 750W geared hub motor. It is beefy and can take a lot more than stock controllers provide. It would make it smoother, quieter, more efficient, provide more torque and maybe a little more speed. Not much 10-15% field weakening to not chance at overheating it.. so that is 3-4 mph without much risk with a 48V or 52V battery. would Luna please program this for use with the 750W bafang fat motor. It is the only geared hub that will work with 190mm fat bikes. It can be squeezed into a 170mm fat bike. We need some fat bike hub performance love in a legal 750 watt form factor. And I want that small controller. There are people with Sondors upgrading to this hub. i am not sure what 750W hub RAD uses. There are other bikes coming out using this motor. A preprogrammed BAC 800 would be the holy grail for a 750W bafang hub owner.

[HIGHVOLTAGE]

ASI controllers are not compatible with the geared hub motors at this time. Sorry.

[New Mariner]

i posted in a thread on FEB that the ASI BAC 800 was not compatible with the Bafang 750W hub. Eric commented that it is.

[HIGHVOLTAGE]

Technically you can get any controller to work with any motor if you wire it properly. What I meant was that it's currently not Plug N Play compatible and we haven't yet programmed it for this motor. If it's not on the website, then it's not an available option.

[Michael albino]

I just got a sabvoton programmable controller wich can be programed threw bluetooth via an app called MQCON.
But when i go into the app to start the hall test and i put in the parameter then press ok nothing happens and the wheel is suppuse to start turning slowly as the test is in progress also when i try to change the dc current , cutoff voltage etc.. i type in the number click ok but goes back to 0 any ideas why this is happening

[HIGHVOLTAGE]

I...don't know what this program is. Sorry. Is this related to something we sell on LunaCycle?

[paxtana]

Hi Michael you probably want to post this to the general or DIY section as this thread is more for Luna-specific questions.
Don't get me wrong, maybe someone else will see this and be able to chime in, but you might have better luck starting a new thread on the subject.

[Eric H]

Considering a Luna BBSHD kit order and would like to know the current lead time on a Wolf 52V battery. Thanks.

[HIGHVOLTAGE]

It's custom so it's typically 2-3 weeks but it can be longer if there's any delays. It kind of has a dynamic processing time since it's based off a lot of factors.

[skymon]

Recently Luna-purchased (20 cycles) 52v GA shark pack. Stops charging at 56.0v. Same on 3 different chargers. Seems it started accepting lower “full charge” suddenly. Possibly balance issue?

if it’s likely a balance problem, could you refer me to specific step by step balancing procedure? Unplug completely from charger? Put a load on it between full charges? Etc.

[xcnick]

Having a choice of 1 to 5 amps, which should one use for this procedure.

[HIGHVOLTAGE]

The charger should automatically adjust as it gets closer to a full charge anyways, but to be safe, you should dial it down to 1 amp as you get closer to the maximum charge state.

[xcnick]

Thanks, I am looking for something unsafe that might bring back an old battery that only gets up to 56.5

[neverwas]

Sorry I have looked around but can't find what I need. There other day my bbshd broke down it gets power but press the throttle and it makes a very loud terrible sound and nothing moves on it. Was just riding home from work all flats maybe 10 min into it. Any ideas thanks.

[HIGHVOLTAGE]

Open it up and check to see what damage you did inside. Probably stripped Nylon Gear or a broken Pinion Gear.

[Anzix]

Hello, I was interested in purchasing the SUR-RON MX and was wondering if you could confirm if it's water proof? Also, I saw mention of a new controller being offered eventually and a pedal kit - are these offered now, what would the cost be, and how would I go about adding those when ordering?

Thank you!

[HIGHVOLTAGE]

For reference, light rain is usually fine for the most part

[paxtana]

Sur-Ron is quite a bit more waterproof than other ebikes due to the industrial design, potted controller, big connectors, design of the battery etc. You'd probably be fine. We gotta say don't use it around water to cover our ass and generally water+electronics is bad, but as long as you are not chucking it into the ocean and you are doing basic upkeep shouldn't be that much of an issue for Sur-ron. Dielectric grease is still a good idea though, and to avoid saltwater.

[Anzix]

Thank you both for the responses. I placed an order yesterday and I can't wait to get my hands on it!

[daren76]

Noob here.

I just noticed the sale on the Cyclone 3000 and want to pull the trigger. My original thought was to upgrade my trike later this year or early next year, and figure that'll still be my plan, but would rather catch the sale while it's here. With that being said, I've done no research on this and my only experience with electric motors/vehicles is with skateboards.

Sun Atlas Trike with 68 x 118 bottom bracket which is a freewheew 20T single speed. My question is about the Triple Chain Ring. I assume this provides a little flexibility with gear ratio?

If that's the case, I definetly want to upgrade but I am not understanding the logic behind the options.

44/44 Stock I assume this means the amount of teeth of the wheel connected to the chain which is connected to the motor is the same ratio as the wheel connected to the chain which is connected to the sprocket?

44/44/24, same as above, but with an additional wheel if you want to reduce the amount of teeth on the wheel which is connected to the chain which is connected to the socket, thus reducing ratio and speed.

48/44/32, 48 increases the size of the wheel which is connected to the motor, which decreases speed/rpm, and you have the option between 44 or 32 on the chain which is connected to the socket?

---------

Second question, is the controller a plug and play controller or are there configuration options with it? Can I put a top speed/RPM limit on the motor via the controller?

My hope is to govern the speed of the trike to a safe speed. I haven't been able to find an easy calculator which would tell me what speed I would expect with the above gear ratios, so not certain which direction to go. I think a top speed of 25mph would be reasonable, or even 15mph in some cases.

[HIGHVOLTAGE]

I don't have much Cyclone knowledge, so someone else can chime in here but if this is your first build. I highly recommend going with something like a BBSxx Mid-Drive kit instead. I think if you have to ask if the Cyclone is Plug N Play, then it's probably going to be a lot to handle with no instructions or guidelines to follow, especially if this is your first build. Cyclones are more for experienced builders who've been around the block a few times. .

Also 25mph is way underspec'd for a Cyclone 3000W. Any BBSxx Motor will achieve that same speed with far less noise and complications. You don't need something overkill like 3000W to achieve those speeds.

[daren76]

Thank you for your feedback, although this is my first build, I realize there are kits available for people who have no experience building electric vehicles, by no means am I looking for something easy. I think you misunderstood my comment concerning Plug and Play. I want a programmable controller and not a plug and play controller. I'm also not sure I fully understand your comment concerning watts and speed. Brushless motor RPM is based off volts, not watts.

In any event, it's been 30 minutes, I guess I will call in.

[paxtana]

The stock controller is not programmable. We sometimes have a bluetooth controller upgrade that is programmable, currently sold out but you can upgrade to it later if you like.

On a mid drive bike if you want it to be at a safe speed while still pegging it full throttle just keep it in a low gear, i.e. you only upshift when you need more speed.

Cyclone is capable of anywhere from 36v to 72v nominal. But even at 52v nominal and a 40A controller you can pretty easily hit 40+ mph on most bikes. Yes voltage is a good indicator of top speed but it is not the sole indicator, and if you dump enough current into a system you can definitely go faster, especially on a mid drive where you can change the gearing. Voltage defining top speed is more a characteristic of hubmotors or anything that does not have variable gearing. Higher voltage may increase motor RPM but with a mid drive you don't need high RPM, as long as the power is there you can make use of it in various ways due to it being integrated with the rest of the drivetrain.

[srkzd]

Hello,

I dumped my Sur-Ron MX/Light Bee in a huge rut on a trail and bent the left/rear brake lever right in half. When I tried to bend it back straight it just snapped right off. My question is can I just replace the lever or do I need to replace the entire rear brake setup? And if I can just replace the lever, where can I get a replacement lever?

Thanks!

[srkzd]

Nevermind, I figured it out. Just going to swap in a new generic Shimano lever.

[Curtis501]

Hey HIGHVOLTAGE and paxtana I finished my Urbano folding bike. I ended up just getting a solder kit and XT90-S from ebay with fast shipping all for $15. I ordered a XT90-S with pigtail from you guys but I do not need it anymore is there a way to stop my shipment? So far my bike runs perfect and shifts perfect and the mini 52v battery is mounted with a plastic water bottle holder, it actually clamps on really good and to make sure I secure it with velcro. The nylon battery case came from amazon and ads padding and better look and almost the perfect size for the battery. With the cygolight, mirror, seat-bag, and water bottle it weights just about 39.5lbs. I used the 48 teeth BBS02 chain ring and that is what the bike had originally 48t. I also switch the folding pedals, grips and crank arms for ones I like. The crank arms are venture2 150mm cranks. I love it. Thanks

[Curtis501]

Thanks paztana, the bag I used for the battery is actually a girls make up bag https://www.amazon.com/Admirable-Ide...eup%2Bbag&th=1 I tuck some of the extra wire from the battery inside the bag. I do not think Luna will want to use the bag, but if so they can, at least you can recommend if your are out of your luna seat bags.I search long and hard to find this bag. I do not think it shipped yet is why I said that. If it did ship then I will just keep it and maybe need it for my next build. You are right about the cadence, I like it that way and more ground clearance too. Thanks again paxtana.

[paxtana]

Ohh yeah I see what you mean there's no mount straps. Still, great idea, but yeah we would probably get complaints :)

Ok I see the order, I have cancelled it out and you'll see refund within couple days.

[Curtis501]

Thanks so much paxtana. This is the water bottle holder https://www.ebay.com/itm/2X-Bike-Wat...gAAOSwhcJWFxiE and you just spread the plastic arms and it graps the battery tight and when you mount the bottle holder you put a piece of velcro underneath when you tighten it and it secures it for you and at the end where the zipper closes just leave it open a little for the XT90 and charge cable to stick out. Thanks again for everything paxtana.

[Lupo]

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

[HIGHVOLTAGE]

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.

[paxtana]

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.
