Proper powering up protocol for X-1 Luna enduro? I have 2 new knees! Bafang is not consistent or I’m doing something wrong?
not happy out on ride and it fails me. Shuts down and won’t restart 1st try.
My 5th ride and always charged. Never easy to start. No instructions have ever been given on how to.

Would recommend to read the instructions linked from the listing: https://electricbike.com/forum/forum...nduro-fs-ebike

This page has both documentation and troubleshooting steps. Most likely it is just a connector partially unplugged.

[Dennis Sullivan]

Sorry that previous note was the problem not the answer.

Hey Luna,

Any chance you'd sell an RSX-RK5 upgrade kit for my Fixed?

It'd be nice to keep the same sprockets and belt since it's got the same 1:1 at the center gear.

[paxtana]

Sorry that's not a product we sell separately, if you are planning on modding this bike with that hub you would need to buy it separately from another vendor and it's not something we have any info on. Wish you all the best of luck with it though

[xcnick]

High Voltage measured the dropouts on Fat Babe and reported the RSX-RK5 is 190mm drop out. Look for SA's RS-RK5 sized for your bike's dropouts. But damn, I want one and it is not even on SA's website. We are about to find out how long SA lets manufactures have this before they sell it to us.

I am installing a BBS02 kit on a hybrid bike (not the one pictured here). Is there any downside to installing the shift sensor in either place shown below? I'd prefer to have it sit on top of the exposed wire. I would securely immobilize the sensor so it wouldn't move around.

[pure_mahem]

I will first say I have the shift sensor and it works flawlessly. However, if you are adamant about not shifting while the bike is under power, You do not actually need it. Just think of it like driving a manual transmission car, you need to let off the gas and push in the clutch before shifting. There just happens to be no clutch lever/pedal. Just giving you an alternative option to consider.

[HIGHVOLTAGE]

I agree with @pure_mahem

I had the shift sensor and while it was cool and all, sometimes occasionally it would not work properly, like 1/20 shifts or so. I found it much easier to just let off the throttle and rotate the pedals a little bit for a much smoother shifting experience. Eventually you get used to it and it becomes like second nature while riding.

[eric_ric]

Thanks for the video, yeah I'll just ditch that shit LOL. I'll bypass some or all of that housing-less section of the shifter cable.

This is actually for my wife's bike, and she will only use it occasionally, so I'd like to make it "just hop on and ride" as much as possible.

[rschoi_75]

Hi Luna techs,
I have a fairly new (approx. 60 miles) luna built bike & 52v wolf v2 battery. I came home today to find the battery leaking some sticky black grease like substance onto the XT90 connector.
The source of the black grease stuff is in between the X90 output and the X60 charging plug.

1) What is this? 2) Should I be concerned? I'm placing the battery outside for the time being. Please let me know.

[paxtana]

That's potting. Let me check with the shop and we'll get back to you shortly.

[paxtana]

Looks like you placed this as a local pickup, yes? If you can drop by any weekday from 12-5pm we can exchange it. Basically the potting just didn't cure totally due to the potting not being evenly mixed. It's rare as we are pretty good at potting, but can happen from time to time. It is not dangerous as it was built to have that in it, but we do want to exchange it for one where the potting fully cured so it is hardened.

[rschoi_75]

Hi paxtana, Thank you for getting back to me about the battery potting. Eric replied on FB as well. To be honest, I'm cool with just using it as long as it's safe to charge and structurally sound. I think I'm pretty safe with losing the waterproofing feature since I'm here in LA. I'll contact support and go from there. Much appreciated.

[j0wn.iv]

Not sure if this would be the best place to ask, but figured it's worth a shot. I have been looking online and trying to do some research for myself and get a better understanding of ebikes. One thing I don't fully understand is the all the Bafang motors. I've seen that the BBSHD is essentially an upgraded version of the the BBS02... and those are the only 2 motors listed on the Bafang website. I am wondering if someone would be kind enough to kinda put things in perspective for me, as to where the M600 and the Ultra fall in line with the BBSxx motors. Basically from oldest to newest... lowest to highest output capacity... as well as which Luna bikes are available with which motors. Is the M600 the same as the Ultra? I am new and just trying to make sense of all the articles I'm reading.

I see the BABE listed with M600 rated for 800w,
The KHS 1000 with BBSHD ludi rated at 2500w,
The X1 with M600 rated at 2000w.

A quick rundown would be greatly appreciated. Just haven't been able to find a clear definitive chart/explanation online after many hours of reading.

Thanks in advance!

[j0wn.iv]

Ah, thank you Pax, I misread. :P
Also good to know about the belt. I really don't know what I'll be getting myself into as far as off road, but if you think I will be better equipped for the unknown with a chain, I will definitely go that route.
It really is nice to have a responsive community forum here. I would be lost without it! Haha.

[paxtana]

No idea on the specific weight for medium khs 1000, but yes khs does not give that out as it varies depending on all sorts of factors like model year, size and components. Google says the average fatbike weight is around 33-36lbs so between that and the ~12 lbs of motor, and ~10lb battery it may be something like 50-55 lbs fully decked out with the equipment. This is an educated guess, don't quote me on it.

BBSHD does not have torque sensor it uses cadence sensing. If you program it with Limitless profile from our configuration software it provides good pedal assist that is comparable to torque sensing. And since it is fully programmable you can fine tune that further for your particular riding style. PAS in a properly configured BBSHD can be as good as torque sensing. I think cadence just gets a bad rap since most folks are too lazy to get the configuration dialed in.

[j0wn.iv]

Gotcha. Anything with big tires and a decent amount of power, coming in at under 65 lbs is a win in my book haha.

I agree! Despite not having experience riding with either, I have noticed almost all reviews seem praise the torque sense over cadence. I am somewhat technically inclined.. in that I worked in automotive for 6 years and have done a lot of wrench work. Never really any tuning, but with a bike being much more simple, I am comfortable that given the necessary hardware/software I could safely configure those settings. I knew it was possible, because I have been watching Jack Cecil on YouTube dyno tuning his Sur Ron with a 72v battery haha. I think he's using a different controller though... Either way, good to know it is possible to tweak the configuration of the BBSHD to different riding styles.

Sounds like the KHS will be a great first bike for me to break the 10 year gap of not having wheels :]

[eric_ric]

Question - is any data stored in the display unit for a Bafang? I'm hoping everything is stored in the actual mid-drive control unit? Why do I ask, I think this picture is the answer =( So I need to replace my display, and I'm hoping all my odometer, etc will be unaffected.

BTW stay clear of F*^&*NG "Saris Freedom Bike Hitch Car Rack". It has a design defect where the top mount has a bolt that loosens and then suddenly your bike drops off the back of your car into the middle of the road!

[eric_ric]

Hmmm I guess I could hookup an Arduino to simulate the speedo sensor pulses and just let it run for however long until my new display odo counts up to 2,000 miles =)

[HIGHVOLTAGE]

You should be able to switch between wattage and current in the display settings. Battery % has quite never been accurate for any of the displays though unfortunately. I would switch it over to a voltage reading instead using the display settings similar to changing to current.

https://electricbike.com/forum/filedata/fetch?id=46252&d=1521089057

This chart is super handy for measuring voltage :)

[eric_ric]

Thanks, I'll order up the Might Mini then! I might print that chart, laminate, and tape it to my frame for easy reference =)

[30pointbuck]

Will the 3000 watt cyclone work with a 2020 Rocky Mountain Artic 20 fat bike with 100mm Sram BSA DUB bottom bracket? Appreciate any help!

This will be helpful :) I'd recommend reading over it.

[Tim Blodgett]

My sur-ron came today with a damaged connector from the controller where it connects to the battery. I sent an email with pictures but am holding of from unboxing it until I hear back from them. How long does it usually take for support to respond to an email. Been waiting 4 weeks so time is kind of an issue. Thanks.

[HIGHVOLTAGE]

4 weeks??? We respond within 24 hours to most emails almost strictly. Are you already in contact with somebody from email and just awaiting for a resolution? Or have you really not gotten any response at all? If no response, double check to make sure the email you're sending it to is correct. It should be support@lunacycle.com

Maybe try sending another email just in-case.

[Tim Blodgett]

Sorry four weeks for the bike to be delivered. i sent a reply to support from when they contacted me about the bike being delayed before shipping. I have not had a response and was just wondering how long before they usually respond as I dont want to un-box the bike until i know how they want to go about replacing it. Thank you for leting me know the time frame.

[paxtana]

Hi my colleague is working on a reply to you right now, really depends on whether you feel you can swap the connector. He is making you a video on how to do it.

[Musky]

What is the purpose of the USB port on the Luna X1? Tried to see if would supply power my IPhone and there was no charging to it. Is it’s only purpose to program the unit if programming becomes available? Also is there another display available because the existing display is very hard to see?

[AZguy]

They are typically charge ports and don't do any data

iphones are fussy about charging and usually require some handshaking with the charge port to accept charge - this port may be a "dumb" port and either only present the voltage without any handshaking or don't support the handshaking the iphone expects

Try a "dumber" device or three and see if those charge

[Evil Toad]

I recently purchased and built an eBike with the Black Friday Ludicrous kit. It has been running great. About 160 miles so far, no major problems. Yesterdaay while riding in a very technical, bumpy, rooty trail, the whole system just died suddenly. No power. Screen blank. I know I had a lot more juice in the battery. I was running a Luna Wolf 30q 625mah battery. Motor and controller was cool still, I could pedal without the power. I checked all connections. It would not power up even the display screen. I decided to pedal it back to my truck to take it home and diagnosed. Rechecked all connections. Nothing. Put in my spare Luna Pup and it worked. Took it for a test ride around the block and everything worked like normal. I replugged the Luna Wolf and it went on intermittently then died. I checked the voltage with a meter and it read 47.5 volts left, which is a lot. I popped the LLuna Wolf on my charger and charged it at 2mahs until it charged a volt, 48.5. Blew out the connectors and the channels between the on the battery with compressed air, and plugged it back on the bike. It powered up like normal and I took it for a test ride and itʻs back to normal.
What would have caused the power loss? i did reprogram the controller with a Black Box to the Hot Rod settings, and made sure bumped down the amps to 25 (which is 50 because itʻs aLudicrous controller. The battery protection was same as the Ludicrous setting, 41.
Advice on troubleshooting and checking battery etc on what could have caused the sudden power loss.
Thanks.

[paxtana]

Most likely the case was one of two things.

First would be that the battery was fully plugged in, and was not just plugged in to the point of the antispark resistor, or that the connector got partially yanked out while riding. Doing so could burn up the resistor fairly quickly. This video explains that https://www.youtube.com/watch?v=7Pwd...ature=youtu.be

Second would be if saltwater got onto the connector backplate. As it dries the salinity goes up which increases electrical conductivity and could lead to a partial short. On the newest Wolf batteries it has already been treated for this with a new upgrade we developed, for earlier v2 buyers we emailed about 2-3 weeks ago about prepping to ship out an upgrade kit. We are prepping these upgrades for shipment but awaiting a part from China which has been delayed due to coronavirus, but you should have at least gotten the email about avoiding saltwater in the meantime. Here is a copy of that info http://lunacycle.com/winter

In either instance you should be able to gather more information by taking a close look at the back of the battery. Is there salt buildup? Is there a melted green resistor in the xt90? That should tell you more.

[Evil Toad]

Makes sense. I first checked the connection to the battery as i though the connector might have undone itself from the really bumpy trail. Also checked to see if there were any burn marks when i got home. None that I could see. I did transport bike with battery in a brief but hard rain and wondered if water got in between and behind connector. Im away from the ocean so I dont think saltwater is a problem. I will check again tonight to see if thereʻs any burns. I did get the email on the kits being sent out to back fill the spaces between connectors on the battery but have not received it yet. Thanks for the explanation. Is there any thing I can use, epoxy, sillicone etc. that I could use to do the task instead of waiting for the kit?

[paxtana]

We have the conformal coat. It's the plastic cover we are waiting on. You probably have the type that is bolted on with allen bolts or torx screws, rather than the earlier packs. The earliest packs were riveted in place, but yours probably is just bolted. You can unbolt that cover and let it dry out, and spray away any debris, salt etc, and inspect it closer.

If there is a large amount there is also special nonconductive, nonflammable electronics spray that could be used to remove salt. https://www.alliedelec.com/product/c...6300/70206031/

The cover we want to replace it with is a special fire retardant material rather than straight plastic. Ideally we would wait until we have everything so you can bolt on the new cover after you upgrade the waterproofing. But it would still be useful to get a closer look and see if water has caused any damage. Likely if it is not saltwater it should be fine.

I would recommend to email support@lunacycle.com attn:Seb for further coordination on this.

[Torreyjaye]

How do we connect to get answers?

[HIGHVOLTAGE]

Hmmm you'll have to be more specific. If you have a technical question, this would be the place to ask :)

[DB60]

Do you have any Sur-Ron Black Editions with Rock Shox forks left for sale?

[paxtana]

Sorry those have been unavailable for many months and that was a limited edition, unlikely to ever be something we can get again..

[DB60]

Ok thanks..

[melechmet@yahoo.com]

Hi when will the Bafang Ultra unit be available for sale again? Thanks

[HIGHVOLTAGE]

Hmmm, Not sure if this will ever be available again.

[melechmet@yahoo.com]

Will there be a variant offered to fit the same form factor? I bought a custom frame for it, was planning to get it as soon as frame arrives (1-2 weeks)

[HIGHVOLTAGE]

Ehh sorry, I have no info on future unreleased products. No clue. That doesn't rule it out as a possibility though.
