Hello, going to go with your fat ebike kit 1000W, my question is for the rear setup will it fit 177mm rear hub spacing?

Thanks!

[paxtana]

Dropout specs for every hubmotor should be on the listing

[Scoonie]

Look it up yourself, now THAT is customer service!
I have one and it’s confusing since Luna lists it as a FB motor, but is only 135mm.

[HIGHVOLTAGE]

Don't be gettin' too snarky now...It's sometimes best to tell the customer to check the product pages for information like this because they might find answers to other questions they didn't know they had while looking. Plus we're trying to encourage this behaviour to help reduce questions in this thread from being repeated and can also help us with fixing any website description errors we might have.

I am using your 300W 36V Advanced charger to charge a Sondor-type bottle battery. When it gets to the end of the charge, the charger cycles on/off quickly for a long period of time. I was a bit afraid to keep using it like this. I did read in some posts that this may be "normal" with the charge capacity setting at 80 or 90%. I then set it to 100% and saw the same problem. I then used the cheap charger that came with the battery to "top it off" to 100%. After it stopped charging I reattached the Luna charger and it did not click on (sensed 100% charge) so it does seems to be able to turn itself off. So will this on/off cycling eventually stop when it reaches the final charge? Should the charger turn itself off after it hits 80/90/100 depending on setting or only when set at 100%? I'd hate to have to physically unplug the charger to stop the charging as I was planning to just leave it plugged in overnight for a partial 80% charge.

Thanks in advance for the help!

[HIGHVOLTAGE]

Was it always doing this or did it just recently start acting this way?

[sepling]

This was the first time I've used it.

[HIGHVOLTAGE]

How long did you leave it originally plugged in and charging for after it shut off?

[steverichab]

Hello,
I have two 27" e-bikes with original Magic Pie 3 rear hub motors (48 V & 1000 W) both internal controllers have now failed and I have tried the "universal" replacement internal controller and it does not fit. Could you recommend an external controller? I am concerned that my existing wiring harness may be difficult to adapt so possible new thumb throttle and breaks my be needed also.
Thanks in advance, Steve

[HIGHVOLTAGE]

This thread is mainly for Luna products only. It's kinda hard to troubleshoot non-Luna products since we don't always know the regular issues these kind of motors experience and we usually don't recommend mix & matching parts from other kits since it tends to cause more problems than it solves. Plus making a confirmation that X controller will fix X problem is usually just a wild guess that could lead to more problems. It's better to contact the original manufacture/seller for information on a replacement controller or...well if you ask me, at this point I'd just start over with a new kit like a BBS02 or BBSHD. The parts and troubleshooting for them are far more widely available than the Magic Pie motors.

[BK Xray]

I'd contact Gary at Golden Motors Canada. He's helpful and knows what's what on Golden Motor products.

[weetard]

so im getting the BBSHD, can i buy any chain ring off amazon and that will work with it?

example...

i want a red one, can i get this one...how many teeth do i want?

https://www.amazon.com/RaceFace-104mm-Single-Chain-Speed/dp/B00D3FG5MG/ref=sr_1_7?ie=UTF8&qid=1538259282&sr=8-7&keywords=red+chainring

[HIGHVOLTAGE]

Unfortunately not

https://lunacycle.com/luna-bbshd-130bcd-chainring-adapter/

but if you use this adaptor, you can use any 130 BCD chainring, otherwise you'll have to use a BBSHD specific chainring like the Luna Eclipse, Luna Mighty Mini or the Luna Eclipse.

PS. If you're interested in choosing a different chainring with the BBSxx kit, you'll definitely want to take a look at our offset information guide on our forums. Since they all have different offsets, some are only best with proper spacing and a straight chainline. It's usually best to just go with the Default Stock Ring or 42T Luna Eclipse ring for the most reliable setup until you've judged what your chainline looks like first and what kind of potential spacing you can use for smaller or larger rings.

https://electricbike.com/forum/forum/knowledge-base/motors-and-kits/bbshd/20359-bbshd-chainwheel-offset

Here's an example of a bad chainline using our Mighty Mini 30T improperly, This chainring is known to be the most problematic without proper spacing due to it's mostly flat design that doesn't offset the chain very much:

https://electricbike.com/forum/filedata/fetch?id=3869&d=1460312982&type=full

These types of issues can cause noise problems, chain wear, chainwheel rear which all lead to chain skipping/falling off and getting jammed up in the motor. Not good.

https://www.amazon.com/RaceFace-104m...=red+chainring

thanks for all that info. so my understanding is i can use this ring with that adaptor you linked?

https://www.amazon.com/T-best-Single-Chainring-Aluminum-Mountain/dp/B07CS2YG1P/ref=sr_1_29?ie=UTF8&qid=1538261815&sr=8-29&keywords=red+chainring+130+bcd

[HIGHVOLTAGE]

Yes, that one will work with the adaptor.

Just remember what I said though, if this is your first BBSHD, don't go buying fancy chainrings without checking your chainline first and what you have to work with, especially with the RaceFace's which have no offset at all and will probably throw your chainline way off. Everything will go fine and then suddenly your chain will start skipping across gears and falling off and you'll be thinking to yourself "What's going on? Why does it keep doing that?"

[weetard]

https://www.amazon.com/T-best-Single...inring+130+bcd

copy that. i have made two bbs02 successfully. i do agree though...i will just get the kit first and install...see what i have and then buy upgrades.

as far as the crank arms, would these install correctly?

thanks!

[paxtana]

I do not believe that will work as it is not for square taper spindles and it also has an integrated spider that would need to be cut off. If you want aftermarket cranks you want ones that are, for example, unicycle cranks. There's info about this on the upgrades/mods section of the wiki

Shimano Steps are a popular choice but Lekkie also makes some high quality cranks

OK - BSS02 Shut off problem is persisting. Now I'm getting shut downs even at 53v on my 48v shark pack.

I've bent the cradle pins all the way to make sure there is a good connection.
I've upgraded to the color display to watch my voltage as I ride. It always reads at least 51v.
My latest shutdowns are happening even when I have a full charge. It shows 53.5v on the monitor while riding. After shutdown, I check the charge with a multimeter and I'm at 53v. The indicator lights on the battery pack are all green.

I can usually get the thing to stay on for a ride home after unplugging and plugging the battery pack to the motor several times and turning the system on again. Not sure if this constitutes a power cycle, but something about it gets me home.

I have three charges on my system and less than 100 miles.

I've checked the BMS plug inside battery pack. Still getting random shut downs (even when bike is stopped, not moving) at 53v charge. Put it on charger just to be doubly sure - wont charge any on the advanced charger. Today while I was able to get it to run on, I noticed the motor starting and stoppin on level one PAS, pedaling on flat surface.

The kit has never worked properly - i'm getting desperate!

I recently ordered the cyclone XL. There are specific blue, yellow and green wires on the motor and controller. They are very dense wires that I need to extend for my e-bike build. What gauge/type of wire is required for this extension???

[paxtana]

Those are the phase wires. A lot of power is going through them, I would not recommend to extend it unless you really have to.

The gauge needed is proportional to the length needed. If you need an inch or something then just measure thickness with calipers and buy whatever gauge matches it, but if it's a significant length then you may need to replace the entire length of each phase wire with thicker wires. If this is not done they may heat up during use and potentially burn up.

[verticalvike]

Hello I am looking at purchasing the BBSO2 kit and would like to use with existing batteries I own. They are 48V lithium batteries. The question I have is how will I convert the wiring from the BBSO2 controller to the battery. I have attached a photo of the battery and current connector.

I am thinking these are Anderson Powerpole but looking for verification.

[paxtana]

The battery should have wires coming off of it. If not and it's a hardcase pack I would guess this was removed off of a factory built bike, yes? If so you may need to open it up and run wires from the internal portion to the discharge wiring on the bbs02. Or if there is some sort of cradle this goes in, run wires from that to the bbs02.

[steverichab]

Hello,
I just ordered your 40 AMP controller(Cyclone) and I was wondering if it supported regenerative breaking? Also if I choose to use PAS how is that configured?
Thanks in advance, Steve

[paxtana]

I do not believe it does regen. We don't have much info on it unfortunately, it is mainly used as a direct replacement for Cyclone, so if you are using it for something else that will probably take some guesswork. Like the listing says it is for advanced builders and comes with no documentation..

[commuter ebikes]

When I had wires like that, I cut off those tabs, stripped the wires and soldered on XT150 connectors purchased from Hobby King.

There are YouTube videos on how to solder XT150s.

I use 10 gauge wire through which I pull 40A continuous daily with no issues, but you should use the same wire size that is on there now (it should be printed on the wire).



There are also YouTube videos on how to solder 10 gauge wires together (bottom line is that you intertwine the strands).

Definitely try the XT150 connectors. You will love them!

https://lunacycle.com/220v-luna-charger-52v-advanced-300w-ebike-charger/

Can you deliver this charger with a male xlr connector? Or an adapter?


Thanks in advance!

[paxtana]

We sell an XLR pigtails set on the site in the connectors section if you want to replace the xt60. In theory you could also get an xt60 pigtails set and make an adapter pretty easily. Modding this ourselves is outside the scope of the services we can provide though.

[Pizzabroodje]

How do I connect the pigtails? I assume I'd have to solder it?

[paxtana]

No, not really. Easiest is to use solder sleeves and a lighter.

https://lunacycle.com/luna-solder-sleeve-variety-pack/

You could also crimp it if you have heatshrink butt splices.

correct on factory built bike - it is a hardcase pack. I can take a look tonight on what it takes to open it up. No cradle, as it appears it plugs in using Anderson PowerPole connections

[paxtana]

You can probably salvage the original off of the bike, if you wanted to, just remove the plug and wiring that the battery was plugged into, then run that to the bbs02.
otherwise you may need to get an anderson pigtail from somewhere

Does the Bafang Ultra series (Motor: Bafang Ultra Max 48V 750 Watt Middrive 160 nm torque) program the same as the BBSxx series motors ? I want to add one of the Luna parts twist throttles but have linear acceleration instead of just 100% ON or OFF.

THANK YOU.

[HIGHVOLTAGE]

Yes, but I believe the torque settings can't be adjusted. However the throttle should be linear. Is this an issue you're having with your Ultra motor?
