What part number would you recommend for replacement hall-effect sensors for a Cyclone 7500W motor?

I used the LunaCycle controller that came with the kit, and I thought I blew it up when the freewheel clutch failed and I backdrove voltage into the controller, but now that I've switched to a Kelly KEB controller it is telling me I have a hall-sensor fault.

When I tested the sensors on the bench using an oscilloscope and spinning the motor by hand (Well, by wrench), I indeed saw poor outputs from two of the sensors. (Not going all the way to ground, bouncing around around ground and intermittent high-going pulses where they shouldn't have been)

When I opened the rear of the motor, I see that the magnet cup has been grinding on the tops of the sensors, so I assume they got ground away a little too deep to function properly.

Since these seem to be compatible across controller manufacturer, I assume someone has found high-temperature hall sensors with the correct switching characteristics and I can just replace them.

Does anyone have a recommendation?

[Tommycat]

SS41Gs are commonly used in BLDC motors as hall sensors. I believe this is the latest model.

[AlanKilian]

Thanks, I ordered some from DigiKey.

On one of the Facebook eBike DYI forums someone advised me to contact you. I'm looking for a Hailong battery case power connector replacement. The four pin one that sits under the case. I saw that there is a new version of it available - 5 pin gold bullet connector. I couldn't find it on your website. Do you have the new or old version available? If so, what would be its cost and cost of shipping to UK, London. Thanks!

[HIGHVOLTAGE]

We don't have it available for sale but you would normally purchase it here:

http://www.ebikes.ca/downtube-connector.html

It's currently out of stock though right now.

[paxtana]

You can email us to set up a special order assuming the shark you have is 4 pin.

I picked up my bbshd kit last week, just got around to fitting it this weekend. I have the 100mm kit on a bullseye monster ltd.
When then unit is fully inserted against the chainstay I have exactly 11.9mm of thread on the drive side. There is no way the lock ring will fit. The chainline is good with the stock chainring there are about 2mm between it and the stay. There is also a gap on the non drive side.
My right pedal is also 20mm further from center than the left. Do I need to move up to the 120mm. It seems like it would be better centered without the added expense of buzz bars. Or should I leave it. I am thinking larger kit with 5mm of spacer on the non drive side and 15 on the drive side. Please advise

[Msim]

BB is just under 100mm but with chainstay intrusion it sits the way it does

[HIGHVOLTAGE]

Yeah, you need the 100mm-120mm with spacers unfortunately. You can email support@lunacycle.com with pictures of it's condition and we can exchange it for you.

[Msim]

I emailed them this morning thanks case#137678

[leeloc]

hello luna,
I've decided to build my first ebike and Im going for power I'm not going to lie. I'm going with your 3000w cyclone and I currently have a 68mm bottem bracket with an ISIS drive! now that Im going to be replacing that with the cyclones bottom bracket can I just order the square 68mm BB with the standard square crank arms, so I don't have to pay $35 for the ISIS version and another $40 for the crank arms? if i just order the standard square will that work or why do you have to pay $70 to have ISIS, is that just a matter of what you feel comfortable with? or if my donor bike has ISIS then I have to order ISIS because of a size issue or fit issue? Im also curious are you still completely out of all your 72v batteries? one last question if I want to order the 3000w cyclone kit will you guys upgrade the controller to the 60 amp bluetooth one for a deal so I can get that controller since theres no batteries I can order from you at this time and have to purchase more expensive elsewhere? please lmk so I can order today hopefully thank you!!

[HIGHVOLTAGE]

For reference, If this is your first bike ebike...I really don't recommend the Cyclone 3000W. You are aware that it doesn't come with any instructions right? For some of the questions you're asking, I don't feel like you should be starting out with this motor for your first e-bike and you should instead try something like a BBS02 or BBSHD instead as they are much easier to follow and install.

I do see a 72v battery on the website currently so they are in stock. https://lunacycle.com/72v/

Also, this is not really the place to ask for deals or discounts. You can email sales@lunacycle.com for a request and see what they say.

[paxtana]

Neither isis cranks nor isis bb (or square taper for that matter) is the same as what's stock on your bicycle. They use this mount standard but it does not mean they are interchangeable. You need all the equipment in the kit in order to use it.

[LazyApe]

Hello, Luna Cycle
I have a 52V Bafang BBSHD. The motor works intermittently. It will start hissing when it starts to work, but once I brake it stops working for a long time. It starts to work randomly like it has a mind of its own. The motor also vibrates and starts to squeal when you put it in 2.

[HIGHVOLTAGE]

Hissing? What kind of hissing? I'd email support@lunacycle.com with a video of this. Maybe try opening it up and give it a lubrication first to see if anything looks wrong or abnormal. Make sure everything is connected too. Check all connections.

https://electricbike.com/forum/forum/knowledge-base/motors-and-kits/bbshd/36670-bbshd-teardown-maintenance-and-greasing

EDIT: Is this with a Shark Pack btw? Unplug it from the cradle and check the underside connectors.

[hawkguy2757]

Hey guys/gals. I am looking to replace the BBS02 left crank arm for an offset arm to clear the frame. Do I need 170mm or 175mm? Also, are there any suggestions on products? I have had a hard time finding a crank arm...

[HIGHVOLTAGE]

Either will work, it just depends how much length you want on the crank arms. Anything square taper that doesn't have a chainring attached to the right crank will work.

Shimano Steps are a popular choice

Any idea when your LUNA FUSION FAT EBIKE KHS 1000 will be available again?

[HIGHVOLTAGE]

Bikes are sold to us at a discount in bulk & are usually last years model from leftover stock. For this reason, we have absolutely no way predicting which bikes will be back or what bikes we'll be getting in the future. We'll be happy to accept whatever we can get :) Since most bikes are last years or this years model, it's unlikely you'll see them re-stock and more likely you'll see another batch of bikes introduced. So it's more of a first come, first serve type deal but it means there will always be more and more options introduced, just gotta make sure to follow our social media & snatch them up when they are announced.

[judevmail]

Yea I am really interested in a 4.8in + tire, but really dont want to go up to the 5000.

[tomasro]

I'm sure you get this question a lot: Are there plans to offer the BBSHD Ludacris motor and controller on it's own? I have the BBSHD and would rather not fiddle with the internal components just to get 45-60 amps from my batteries and then have it melt something inside the motor housing. Thanks in advance!

[HIGHVOLTAGE]

No plans at this time but last month we had a special day where it was available to anyone in Fast Electric Bike group on Facebook for one day only. So I recommend just keeping up with our Social Media and Facebook groups and you might see that deal pop up again in the future.

[judevmail]

There seems to be some contradictory information on the Luna Fusion site:

https://lunacycle.com/luna-fusion-fat-ebike-khs-3000/

These are the two statements:


NEW! This bike features the Luna Fusion 52v 30Q 12Ah battery pack!

and

This Fat Tire Bike with a BBSHD is a powerful bike with a 13.5 ah battery in the triangle is all the fat bike that most people will ever need.

Just wondering which battery really comes with this bike.

[HIGHVOLTAGE]

It uses the 73mm-100mm kit.

[Steve]

Thanks, I would have definitely ordered the 120mm kit as the BB measures 120mm across the frame portion. Are there detailed dimensions for these motors anywhere (link)? Thx

[paxtana]

We can not guarantee fitment if you are buying the frame to do the build yourself as frames vary from model year to model year and we usually convert last year's khs stock if we can get it. If you measure the bb shell itself and it measures 120 then you may indeed want 120. Here's some detailed dimensions

[thanksgivingtorque]

Hello, just registered. I recently bought a 52v luna smartcharger. After I plugged a battery in, the fan worked for a minute, and then stopped working. Is there anyway to restart the fan? The charger is getting pretty hot.

[HIGHVOLTAGE]

Did you plug it into the wall first before you plugged it into the battery?

[thanksgivingtorque]

Yes. It was a new battery too, so I set the charging toggle to 100%.

[paxtana]

Hit us up via email we'll get you a replacement

[fos'l]

Looking at your motors (I have two Luna BBS02's) and you offer "off road" programming on "bare" motors. How will this motor differ from my current units?

[paxtana]

It is programmed for max current, 25A peak. If your current units use 25a peak then same thing. If your current unit has some street legal programming then it'll be higher power.

[madisonhamman]

OK, I've had my bbs02, and 48v chark pack for about a month now - still having shut downs. I've tried everything suggested to me so far (via this thread). Including: bending contacts 'in' on shark pack. Done. Switching to a color display to get more accurate voltage rating. Done. Checking BMS connector inside battery housing. Done. Ensuring im running at 'full charge' with a reading of over 53v using a multimeter - done. Still getting random shut downs around 53v. Please advise.

[paxtana]

Did you rewire the discharge connectors going to the controller at all or is it stock?

If you remove the two screws on the cradle to check the soldering on the pins does it look visually fine?

When it is shutting down what are you doing?

An intermittent problem which occurs at all speed/power levels could be a loose connection or short in throttle, brake cables, gearsensor cable or connectors between controller>motor. A problem that only happens at high load is more likely to be something getting hot. Which could be a high resistance connection or short in the power wiring, or an overheating controller, or an overheating battery.

[bikeride33]

Luna, I have a color display I believe it’s the DPC-14. I’ve had my bike since October 2016 including the screen. I decided to make my display have a password and now it’s telling me my password is wrong. I am 100% certain i’ve entered the right password. I looked around on google but couldn’t find anything like this. I unplugged my battery from the rest of the bike, unplugged the screen dongle, recharge it to 100% and still nothing. This happened after charging at my friends house, i’ve never charged there before so i’m assuming this might have caused this to happen? Any help would be amazing

PS - I have not tried to use the factory password but that will be my next attempt

[HIGHVOLTAGE]

Try 1919 or 1199, otherwise you might be screwed since there's no way to reset it.

[bikeride33]

I tried 1919, 1199, 0000 and 1234 with no luck. I might have to get creative, i’ll let you know if i figure it out.

[henrygilliland]

I have a 48 volt killer whale battery with a 48 volt Luna charger. Everything is new. I charged the battery once with no issue. Went to charge a second time and no luck. I've unplugged and reset about everything I can think of. The green light is works on the charger but doesn't turn red to charge. Any ideas???

[HIGHVOLTAGE]

Did you plug it into the wall first before you plugged it into the battery?

Also, What is the charger doing? Is it clicking on/off repeatedly? Wiggle any adaptors you're using between it and the battery to see if it suddenly charges.

If you have a multi-meter, you can measure the charge port of the battery to see if you're getting any kind of reading.

[henrygilliland]

Yes I plugged it into the wall first. I opened the charger and checked the fuse all is in order. I tested the battery with a meter on the charge port and got a read back of 42 volts. Which is what the controller is saying as well. I also tested the charger and get the same volts as on the readout. The amp readout reads 0 all the time though. Where as when I charged my battery for the first time it had a digital read out

[Tommycat]

"I also tested the charger and get the same volts as on the readout." 54.6 vdc?

[KNOWLEDGE.JUNKIE.369]

This shouldn’t be a major problem, but my new battery just arrived. The Panasonic 72v 100ah battery. I noticed the heat-shrink tubing is badly cracked, should I just put some electrical tape on it?

[HIGHVOLTAGE]

Yeah or you can just give it another layer of Shrink Wrap. Shouldn't be any issue.

[paxtana]

Personally I wrap mine in fiberfix as it hardens into a nice outer shell. Maybe overboard but I like to protect my investment. Got a link on how to do it if you want

[thebootfitter]

Paxtana - What's your link? That's an interesting idea.

I found this one: https://www.youtube.com/watch?v=fOeXkg02iwQ
