Luna Cycle Product Re-stock Requests

[brothergc]

any idea when You will be getting BBHD controllers back in stock ? Also are Your programed By Luna Cycles ?

[brothergc]

Interesting , on the luna website I can not enter my email address to be notified when its back in stock keeps saying " Make selection"

That's because there's version a and b, you probably have version b if it was made within past several years. The restock notifier can't really handle option sets on listings though since it is not supported by the platform. On some listings I remove the option set so email can be left but I can also just have our team manually reach out to you if you want.

shoot still not in :( oh well , guess maybe next shipment ! :)

Any news on when the Ludicrous X2 in a medium frame will be back in stock please?

[paxtana]

Hi there, we do not have a specific timeline for medium but can get back to you when restocked if you like?

[highrisedrifter]

Yes please paxtana that would be great. Question: Could I get a bike with a color 860C display that fully functions with the Ludicrous controller? I don't like the smaller black and white one that comes with the bike.

[paxtana]

Ok we will get back to you.
That display is currently incompatible with the ludi v2 controller but I understand it is something they are working on.

I'm looking for a BBSHD Controller version A. Any word on when they will be back in stock?

Has anyone tried to replace the Anderson connectors on the motor core, with spade connectors in order to switch to the Version B controller?

I'm _assuming_ that my problem is the controller at this point.

The symptoms I have are:

* that the display comes on with a red edge to the batter, but the voltage reading 58 volts, then the battery fills in.
* When I press the throttle, the watts will go up to 1700 momentarily, and maybe a twitch from the motor, then the wats drop back down.
* Now and again the motor will spin like you one would expect. (both in throttle response, as well as to PAS)

I took the controller apart, and _thought_ I had found the problem, with the red wire having been crushed between the controller and the case years ago when I had to replace the core, and maybe it was making intermittent contact with ground. So I soldered it together with shrink wrap, and bench tested it, and the behavior remained the same :(. (note, only the throttle, and the display were connected to the wiring harness, so it's not a shift sensor, or a brake sensor)

If anyone can point me to better troubleshooting procedures, that would help me isolate the problem to the controller, versus the throttle, versus the display, versus the wiring harness I would appreciate it ;)


This is my daily commuter, so I'm hoping to get it back running soon.

waste of time

Golden Motor appears to have some of the type "B" controllers in stock - you'd have to locate some female spade lugs (easy I'd think):

Update - I went ahead and bit the bullet, and ordered a brand new BBSHD motor kit. That came yestereday, and I installed it last night. So far so good. We will see how it does on the actualy commute.

Thanks you stts for the thoughtful reply. There is a bunch of useful information in there that is actionable.

Additionally, you may have a battery old enough to have it's own issues of cell age, BMS issues, or even battery switch issues. So lots of careful checking is going to have to happen here.

My battery is relatively new, and reads a good solid 58.8 volts off of the charger, and earlier this week was showing plenty of volts after my 10 mile 400` elevation gain commute (something like 53+ with no draw I think) So I am going to put that aside and focus on looking at the tiny wires and connectors on the two connectors in there.

After all that, then maybe think in terms of buying spare parts. The controller could be shot. But since it works sometimes, that is reason to believe it is still capable of working all the time. If you can find other problems in the mix.

You are right, neither this time, nor the first time I pulled the controller out (for what was ultimately a core failure when the bearing that the helical gear sits in failed) was I all that gentle with the wires. While I didn't pull on them directly, they are fragile enough that I could see that a bit of rough handling could have resulted in some un-obvious damage leading to intermittent failures.

Thanks also for the pointers on some of the concerns with switching from a version A controller to a Version B controller. This leads me to believe that my best course of action is going to be double check the connectors super carefully with a bright light, and a good magnifying glass, and if there is nothing obvious, replace the whole motor and stop messing around. This is, after all, my daily commuter, and riding the bus kind of sucks :)

Thank you again!

PS - RTV makes a mess, and gets all over everything, so that probably doesn't help either

[stts]

Yea, Im glad you find this helpful and I hope your on the road to cutting loose the frustrations. But I am a huge fan of RTV. But only the right RTV. Most RTV people buy stinks like vinegar when applied. That is the worst stuff for electrical applications. They make NEUTRAL CURE RTV that does not have that stink. And that stink is acid. Which eats away at copper in all electrical circuits. But water moisture also eats away at energized electrical circuits. So you still need to worship at the alter of sealants to keep the water out. But insist on NeutralCure written on the package and you will have a sealant that will do all it can to keep your circuits dry in the outdoor environment. Even morning dew is a fatal thing when the power is eventually plugged in. I will completely seal up my motor with that RTV before I mount it on my ride. Its clear that the factory seal is not totally adequate when people get into water. And they have no clue until the damage is finally done.
