I'd like to get an extra shark battery cradle/mount. It looks like Luna does not offer one. anyone know where i can get one? the kind I want to match is attached.

I've looked around, but the closest I can find is a Hailong 3 (with aluminum section in the tongue). Would that match?

Any assistance is greatly appreciated.

Thanks!

[max_volt]

Looks like the Hailong1 has 6 tab engage, and the Hailong3 has 4 tabs.

[Joe Remi]

Other way around. Hailong-3 is the newer 6 prong, Hailong-1 is the already very scarce 4 prongs.

This looks to be the old 4 prong version.

Hi,

What controllers offer regen brake functionality on the cyclone 3000W? Best if I can buy it off luna website.

I'd like to run regen brake on the cyclone 3000W and I have removed the freewheel but the stock controller doesn't do regen brake as far as I know.

Thanks,

For what it's worth, the Cyclone Bluetooth Controller does show the option for electronic braking in the Android Application.

That probably only really means the controller can be used for many kinds of motors.

Apart from that--and please understand I am not saying it'll do either electrical or regenerative braking--it certainly is true, if you do force the Cyclone motor to turn, it will generate some electricity.

If you're wanting to know for certain, you can also contact Paco at Cyclone-TW (his e-mail is on the Cyclone company's website). Nobody knows the Cyclone motors better than the manufacturer.

Best of luck with your project!

Take care,

Tklop

I want to build a $1k fat bike with bbshd that will truly be a utility vehicle....for 1) kid trailer hauling, 2) solo higher speed suburban paved riding, 3) solo beach/sand riding and 4) solo off-road(some hills) trail riding. 1 and 2 will be majority of usage.

My bike experience: not much.I am 220 lbs with medium fitness who currently rides a single speed flat road bike for casual use and kid trailing.

I do not have a front derailleur but am ok manually changing the chain to different chain ring by hand when on a big hill or casual suburban riding depending on situation. What 2 chainring combo should i order for a 7 or 11 speed rear cassette option to handle most situations I described? I don't care about top speed. I prioritize reliability of motor and good cadence when I choose to use pas.

Is my approach sound for what I'm describing ?Or, should I just go with with 1 chainring and insure a 11 speed rear cassette?

Please tell me what to purchase (chainrings) given the type of riding I plan on doing and links on what to purchase since I don't understand buying chain ring versus sprocket.


Tell me which option will be best for my needs by prioritizing best to worse and filling out sections to link on what to purchase. Cost is not an issue.

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.

Hello. I just bought the new SONDERS X bike (7speed). Was wondering if the STORM HOT ROD 20 AMP CONTROLLER 36-52V will work with SONDORS X?

[paxtana]

It needs some modding and a different lcd which is out of stock but possibly available elsewhere (ktlcd3), not impossible but I am unclear on exactly what needs done on newer sondors for it to work.

[liratium]

I have a bbs02 bafang.750w. In the middle of my ride, the display turned off and won't turn on. I assumed it was the battery but the battery got fully charged after two hours while normally it takes 5 hours to charge from empty. When I connected it to the bike, the display flashed for a second then it turned off. Then, when I try to power it on, it won't turn on unless I removed the battery and replace it.

I'm wondering what could have gone wrong. I have an extra display and the same error persisted. Also, the battery looks fine when I checked I press the button, all led button lit. I saw someone on youtube who has a very similar problem and he claims the problem went away after installing the item in the link below:
https://powerwerx.com/anderson-power...s-15amp-bonded.

Please help and let me know what you think.

Thanks in advance

[paxtana]

Give this a shot. If bypassing turns on the display on the kit then it's something wrong with the battery.

https://www.youtube.com/watch?v=KGibc-kutYA

[liratium]

Thank you, I will try that once I go home. Yesterday, I got the display to run for few minutes and throttle and pedal assistance to function by replacing the battery in a way that it is not perfectly fitted in the mount. But it only lasts for a minute and then turn off.

[paxtana]

Sounds like possibly a high resistance connection between case and cradle. One of the downsides of a hardcase pack is you need to adjust this every once in a while. Doesn't sound like you got the pack from luna but if the seller offers support they may be able to provide some guidance. However many sellers do not offer support if it's some random reseller or something like that. One of the reasons to buy from Luna I spose.

Hello, I have triplets and they each received a Razor MX650 for Christmas. The SLA's on 2 of them are already useless, so I would like to upgrade to Lithium batteries, but I have a lot of questions that perhaps you can help me with. The first question is what type of lithium battery would you recommend for a Razor Dirt Bike that is used off road on a motocross track? I've heard of certain types that are more stable and safe than other, so your input in welcome? The current set up is 36 volt (3 x 12v 12ah batteries), so I'm currious if you have a 36v battery that would give me about a one hour, or more, run time on the dirt track? The track has an elevation change of about 30 feet from one side to the other. The hills are basically large and mid size jumps for a motocross bike like a YZ250, but they are taller than my kids, so they just ride up one side and down the other.

I was also looking at upgrading the motor to a 48v 1600w brushless motor with a 40 amp limit. What battery would you recommend for this setup if I wanted to get at least one hour run time on it? Any help you can provide is much appreciated, thanks.

[HIGHVOLTAGE]

LiFePO4 are much larger, heavier and less energy dense than Lithium Ion. So it's technically a trade-off for safety.

[xcnick]

This is a good. Wake up Paxtana for a diplomatic answer. I bet Highvoltage gives us some techno. (I'm not going away until I hear how the switch on the light works!)

[xcnick]

Ok, Highvoltage walked into the diplomatic side. No seriously, I have the choice for my sailplane, I face the term "relative safety". Running drycell until I become an educated idiot.

[Dinged]

When are 52 V shark packs 13.5 amp hours expected to be back in stock?


Also, when are black eclipse chain rings coming in?

[HIGHVOLTAGE]

We don't have an ETA for either but if you want to leave your email. I can add you to be notified when they come back in stock. Let me know.

[paxtana]

52v Shark is basically discontinued, we're mostly focusing on USA-built Wolf packs for 52v hardcase since it's a better battery.

[Dinged]

I'm in Orange county. Any luna employee's offering conversion labor ?


If not, do these pics reveal enough to determine what would work better 120 or 100mm motor ?



Also, which chainring would be best? I submitted this question before(without pictures) and I received a response that would be difficult to understand without the bike and various chainrings in hand.

If I bring the bike to luna headquarters, Would staff be able to tell me and could I make purchase in person? My goal is to not waste money and time purchasing products that won't work and cause major diy work in getting to work.

Is it possible to buy everything and return what won't work while in middle of build ?Or are there no returns and high re stocking fees?


I want to do this bike:

out of box specs:
chain ring: 36t
rear:7 speed, 14-28 shimano altos
160mm mechanical disc Brake

[Joe Remi]

As they mentioned before, your best bet on chainring for BBSHD is to just run the stock steel 46 for a while and see how it feels. You're trying to do a lot of things with this bike, which means you're going to have to find a compromise between hauling/climbing torque and top speed. 46t is probably the top end of what you can get away with, and you'll know soon enough if you need even smaller so you don't burn the motor up grinding in too high a gear.

[HIGHVOLTAGE]

Yup, Joe is correct. Keep it simple by going with the default ring first and see what kind of chainline you have, how it works and what kind of play you have to work with before messing with different sizes and offsets. Luna doesn't offer conversion services unfortunately, it's more of a DIY type deal where you have to learn as you go.

I should tell you now. If you're going the DIY kit route. You're going to waste money & time. That's just simply the nature of it. You'll learn a lot on the way though.

If you want to do a build that's relativity problem free, you can try to base your build off of somebody elses build that has been documented already. There are plenty of resources for that here:

https://electricbike.com/forum/forum/builds/ebike-building-directions/14811-list-of-bike-build-threads-to-be-bbshd-or-bbs02-compatible-pictorial

That or just go pre-built.

EDIT: Oh I forgot, there are some E-bike friendly shops you can check out that might offer a conversion service for you. One of them that springs to mind is Madman E-bikes (highly recommended if you're near him)

[Bob363]

I have a 52v Panasonic 13.5ah GA battery I'm wondering how far to discharge the battery to maximize the life? I have seen your thread on charging slowly and only to 80% but haven't seen anything on how far to discharge. Any advise would be appreciated.

[HIGHVOLTAGE]

I generally stop at about 30% (47v) and reserve the rest for emergency power.

[Bob363]

Do you only charge to 80% or do you go to 100%?

[HIGHVOLTAGE]

Depends. I'm not super strict about it since I know they don't last forever. I'll charge to 100% only when I plan on using it immediately afterwards. Otherwise I keep it stored around 40-50%

[noahp99]

The sprocket on my new Cyclone 3000W motor wobbles slightly – maybe 1 mm or so. I posted a gif that shows it fairly well. There is also some oscillating motor noise in sync with the wobble. I've only bench tested the motor with no load. Is the wobble/noise expected?

[paxtana]

From the gif it's within tolerances. I would prefer it to be consistent down to the last nanometer but that's not practical for most machinery.

Odds are it's never going to present an issue, but who knows, maybe it would. Spose you could keep an eye out for chain skips from motor>chainring. Most of the time if the chain is skipping it's from chainring>cassette and there's no issue at all with the sprocket on the motor itself. I wouldn't worry about it.

[noahp99]

Thanks - Yeah, it seems like the wobble isn't enough to cause chain skips. I'm more concerned about the oscillating motor noise. You can hear it on each rotation - definitely noticeable above the base motor noise. Is that anything to be worried about?

I would get an 11 speed steel 11-46 Sunrace cassette, and use the 42 Lekkie or 42 eclipse, depending on what gives you the best chain line. Eclipse would not work on my fatty. The 42 lekkie works well. this set up will give you torque and decent speed.

You need to verify whether you have a cassette or a freewheel. From your pictures it looks like you have a freewheel. No 11 speed love for you. I would get a sunrace 13-34 8 speed and tune out the smallest sprocket. Your rapid fire shifter will work with it. Or replace with an 8 speed rapid fire shifter. Under 20 bucks. As long as you don't have any really steep hills the Lekkie 42 T would be my initial choice.i would also get the 30T mighty mini. Get a self extracting crank bolt set, and install one on the drive side. M-8 size. It will make removing your crank gear a quick and easy one tool solution. There are several different ways to do a dual gear set-up with a fat bike if that is something you want to explore.

[New Mariner]

This is one example of a dual gear.

[New Mariner]

What size anderson connectors are on the old style controller and motor? What amp rating? do the older motors have a thermister wire?

[HIGHVOLTAGE]

They're all rated for 30 amps I believe? Can't remember if it's the 30 amp or 40 amp version.

[New Mariner]

How many amps go through the phase wires?

[HIGHVOLTAGE]

We're talking about the BBSHD and BBS02 right? Since the BBSHD can handle 2500watts, it's safe to assume they can handle up to 50 amps but by default it's just 30 amps.
