Why doesn't a chainring for a BBSHD work on a BBS02? Is the bolt pattern the same? Is it just a difference in offset?

I have a stock Bafang 46t chainring for my BBS02 that has an offset of 9mm and I need more offset so it lines up with the center of the cassette. Currently it is inline with the 7th lowest cog and I need it to be inline with the 5th. I'm thinking if the BBSHD chainring will fit, it will correct my chainline issue because it has 19mm offset so I will gain 10mm. The space between the 7th and 5th cog is 10mm.

Any thoughts?

Different bolt patterns. Use this thread here:

Hi, I tried posting this in the troubleshooting forum but met with zero success.

here are links to the two posts:

https://electricbike.com/forum/forum/main-forum/trouble-shooting/81886-long-beep-from-bbshd-display

the person answering that with "Mine doesn't do that nor does any of my riding buddies" makes me think maybe my unit is defective. Or the 48v 24Ah battery is bigger than his and thus I have the capacity to make it beep (that is if it is an overwattage warning as I suspect.

the other post:

https://electricbike.com/forum/forum/main-forum/trouble-shooting/81885-smart-charger-doesn-t-stop-at-80

Again, the forum member replying is just asking a question, to which I provided the answer, but then nothing....

For the answer here, I'm just wondering if the battery being out of balance could cause the smart charger to refuse stopping at 80%.

I suspect the answer is no and I'm using a defective smart charger. But I figured I'd save somebody some time at Lunacycle and get an answer here.

just wanted to confirm that.

[HIGHVOLTAGE]

Check everything. I've heard of some customers reporting beeps when there's an error code such as Error 21. Check your speed sensor, check your brakes, check your connections and make sure everything is tight and properly secured, no crimps, no bends, make sure you're getting a speed reading on the display. And check for any error codes on the display itself.

For the charger, it probably just needs to be adjusted:

Hi, Im placing an order for a BBSHD and battery kit on your anniversary deal. I thought I saw somewhere on the site that a tool kit would be included. Is this the case or do I need to purchase the Luna wrench as well?

Thanks,

James

[HIGHVOLTAGE]

Toolkits & Luna Wrench are two separate items. Neither are included but it depends on what you're doing whether you'll need the toolkit or not. You will almost certainly need to purchase the Luna BBSxx Wrench for installing the motor but if you get a local bike shop to handle the rest like removing your BB and front derailuer, than you won't need the toolkit per say. But it's always good to have bike tools on-hand :)

Hello, who can I talk to about a Luna order that I need to modify? Your order ID is #71194.

[paxtana]

We can't modify orders but assuming the order has not shipped we can cancel it so you can place a revised order. Ideally you would email support@lunacycle.com for this sort of thing as this thread is more about technical questions, but I can cancel it if you want.

[paxtana]

Just following up here since I did not hear back from you. In the interest of not shipping something you don't want I have canceled this and we will email you refund notification once processed in a business day or so. Feel free to reorder at any time with the changes you need.

I recently bought my first ebike (used) and have been upgrading it. I interested in improving the motor to get more out of it and have a couple questions.

Does my Luna BBS02-B have the 3077 controller?
Would it come with “hot rod” programming?
If yes to both, is there more I can do to it to get more power out of it?

[HIGHVOLTAGE]

When was your BBS02 purchased? If it was after 2017, it probably has the 3077 controller. You can request for hot rod programming settings during the checkout. Just add it to the comment box. There's no way to get more power out of the BBS02 unfortunately. You'd likely just end up burning out the unit anyways .

[wyojoe]

I thought all B versions came with the 3077 controller.

I guess the only way to determine if it is tuned is to buy a programming cable and look at the data. Right?

[HIGHVOLTAGE]

Same thing, the B model was introduced in late 2016ish. The programming settings won't tell you which version you have though. You need to look under your controller and see what the label says. It'll either say BBS02 or BBS02B

I bought a Mighty Mini battery. It came with a volt meter and tape. I taped it to the side where the wires come out, but it looks a little strange sticking out with the PCB exposed. Is there a suggested way to mount the volt meter so that it looks nice and is water resistant?

[HIGHVOLTAGE]

The volt meter is included as an extra. There's no real standard way to install it though. I guess you could probably go crazy with the glue gun and form some enclosure. I'd probably recommend not keeping it plugged in all the time and to only use it when you need to check the packs voltage.

I took a spill on my bike this morning, it's a Luna Folding Bike. Most everything seems okay except my left brake sheered. How do I go about ordering a replacement? I'm not sure if these are special for e-bikes, as it's got a wire attached to the motor, or if any brake lever will work.

Hope you're ok!

The wire/lever switch is a safety feature, and shuts the motor off when braking. You don't have to get a switched lever, but I'm uncertain whether you'd save that much buying a replacement lever from a LBS as opposed to from Luna (here or here):

[gotmayonase]

All good, just a scraped up elbow and bruised ego. Thanks for the info, got a couple ordered!

[judevmail]

Are there any directions/tutorials on how to add the Ultra Gear Sensor, (https://lunacycle.com/gear-sensor-fo...nd-max-motors/) to the Ultra motor? I dont see any instructions on how to do it. Thanks!

[ncmired]

I think the motor connector you're looking for is a white, male, 3-pin "HST" cable stub, coming out of the top-back-right corner of the motor, behind the chain ring - I think (I don't own one). To install it on the shift cable, remove 80mm of the housing where you want the sensor located.

[judevmail]

I am assuming you mean these instructions for attaching the sensor to the ULTRA? Am I opening up the motor to get to a plug for the sensor? https://www.electricbike.com/manuals...or-manual.html

Question about brand new Luna battery. I just received a new 52volt battery and a smart mini-charger today. There is a extra Xt60 connector with black shrink tube on it that is not in the manual. I assume that it goes between the battery and charger when charging the battery. Is it a spark filter??

[HIGHVOLTAGE]

It's a resistor to prevent the charger from entering a low charging state mode. Should be good to just leave it plugged in :)

I purchased Lithium Cycles Z for its frame. I figure I could buy aftermarket parts to upgrade it. Opening the custom cased seat that houses a 36V 11.6AH battery and controller, I noticed that there is a cable left not connected. How can I figure out what I can do with it? Also note that this bike didnt come with a display

The controller limits the speed to 20mph. I am trying to install a headlight and brake lights to this system and increase the possible speed limit.

If I wanted to "upgrade" the entire system. Hub/Battery/controller. What package would you recommend?

[paxtana]

Your power is ultimately going to be limited by the battery. Even if you changed the controller and motor, the battery would not be able to handle it. TBH you would be better off selling the bike and starting over with a higher powered kit on a 52v battery, otherwise you are looking at a total rebuild and a lot of wasted money and spare parts.

No idea what the connector is, you would need a wiring diagram from the seller.

[Sarmst1]

Thanks, Its really just the frame I was interested in. I don't mind investing in a cool project.

It has a 500W hub on there. Would upgrading the rear hub make much difference if I put a 48V/52V battery on it?
Would you recommend the Double Gear/Double Torque? Can I lace that to the existing wheel?

[paxtana]

The hub is not where the bottleneck is. It is probably the only part of the system that can handle significant overvolting. This is not like a gas motor where the bigger the motor the more the power. DC motors are just big electromagnets basically. It will produce torque from whatever power you give it until it burns out from excess heat. So the question is how do we send more power? You need a better battery and a better controller, and any needed accessories to make that work.

We don't make compatibility claims on stuff that is not from our company so I can't help you there, but generally the double torque requires stretching the dropouts considerably, which can be problematic depending on the frame. Measure first and check the specs on listing to see compatibility.
