Customer Experiences

I bought a Bafang bbshd on eBay with a bad controller. I knew from previous experience that Luna has great prices and fast shipping on items. I purchased the controller and installed it with no problems. The motor works great now! I have bought several things now from Luna, and have been very satisfied. I will need a new chainring soon, and will no doubt get it from Luna!

Always super easy and never disappointing ordering from Luna, speedy shipping and notifications at every stage of the order. Price for the controller was cheaper than other US sites, was simple to fit, I'm back on the road again :)

After recommendations from several electric bike forum members as I attempted to fix a sudden and ongoing loss of power and torque on my BBSHD to a maximum of 400 watts or 2/3rds power loss, I chose to go with a new controller. Apparently, moisture had migrated into battery cradle and resulted in voltage arc that fried, Not All, but a portion of old controller. Replaced battery cradle and purchased a replacement LUNA CYCLE Version B BBSHD Controller. Great News! I’m back on my DIY Build Specialized Stumpjumper and at FULL SPEED, TORQUE AND POWER! Kudos to Team Luna Cycle. Thanks again, Dave Lowney

After about four years of use I fried my controller on a hot day climbing rocky ridge on Mt. Tam in too high a gear. Luna sent me a replacement controller, which arrived quickly. I followed the linked directions to install it. I did a couple of mods to insure that I don’t overheat the controller again: 1) installed aquarium thermometer per the article linked to the replacement controller on the Luna website 2) changed cassette to a Microshift 11-46 for a lower low gear. While I was into the motor, I replaced the stock nylon gear with the upgraded Luna product. I also added a dropper post. My motor is fully upgraded and my homemade bike rocks. I have to be on the brakes on the uphills to go slow enough to ride with my buddies who have Specialized Levos…which cost 7.5x what I have in my bike (not counting the cost of the old bike). They blow by me on the downhills cuz my 16 year old SC Blur has old school geometry and I’m a somewhat cautious senior citizen. Luna keeps me out there riding all the trails on my DIY bike.

After I ripped the speed sensor out of my BBS I was very glad to get a new controller quickly. I was surprised to find only Luna Cycles had what I needed in stock. Price and shipping time to Europ was competitive with European suppliers.
- Bafang replacement controller only for the BBSHD
- Easily user replaceable with only a few bolts a 15-30 minute job
- Can handle 48v or 52v batteries for up to 1600 watts of power peak power
- Factory Programmed for a peak output of 30amps
- Lunacycle custom programmed with 'Hot Rod' settings
- You will be able to use a throttle only mode in PAS 0 unlike inexpensive units purchased directly from China and not custom programmed
If you want your firmware to allow you to apply as much throttle as you want regardless of your pedal speed, this controller is good insurance your set up will be able to deal with whatever power you dish out.
Installing the new controller is an easy job that any person with basic mechanical skills and standard tools should be able to do in less than 30 minutes.
We recommend installing a thermal probe inside the drive unit so you can track the drive unit temperature. (Click here for probe installation instructions)
Read this guide on the different ways this firmware can be programmed on this beefed up controller. (Click here for programming guide)
If your BBSHD does not work it's not necessarily the controller that is bad, you could have also have damaged the nylon gear or melted the windings. For a complete troubleshooting guide for the BBSHD (click here for troubleshooting guide).
Versions
Most likely if you have a recent BBSHD you want the version B controller. You can see the difference in the plugs in the picture above. Version A was the first type and uses Anderson connectors, while latest BBSHD controllers use flat spade connectors. You can pull the controller you already have on your BBSHD to visually compare.

I need one for 52 volt,correct me if Im wrong but doesnt the firmware have to be changed from 48v to 52v or you will get overvoltage errors. Can you flash one when I decide to buy?.......Like today(monday 5/3/2021!!
We will send a verification email to confirm your answer. All responses are subject to store approval.
Hi, no you do not get overvoltage error if using with 52v. You would only get overvoltage if using above 52v nominal, i.e. 60v or higher. That said, most displays are built for 48v nominal so if you have a good one (any of the color ones) be sure to set it to voltage rather than percentage or it won't show correct percent
I cant chose option A.

Does your replacement controllers have the wiring for lights? I don't see it in the picture but I though the newer ones come with 6v lines for headlight and tail light.

Re This thread: Joan Lane, Someone answered your question: Hi. Wondering If This Controller Is Wired For A Gear Sensor. Also, My Problem Is Related To The Throttle, Likely A Phase Connection. Do You Think I Do Need To Replace The Whole Controller? Answer: "Yes It Has Gearsensor Connection. No Idea If You Need A Controller As We Don't Know What You Have Attempted Thus Far, But It Is Always Handy To Have A Spare Around Just In Case You Ever Do Need It." I've replaced the throttle and the problem persists. The throttle has power which does not increase...one gutless speed. I'll look at the phase connections, but if it's a hall sensor, that's going to hurt. Possibly I will order a controller for back up.

When purchasing the BBSHD 1000 controller, do I need to inform Luna about what the voltage is in the battery that I am using in order to get the correct HotRod programming? Such as 48V vs. 52V ?

Does this new controller unit affect the battery readings?? With my DCP 14 display, when I scroll to the INFORMATION page that has advanced battery status information, my fully charged 48V battery is said to have a 72% charge, but still reads 54.6 v. Something is screwy here. I wonder if this newer controller's compatability with a 52v battery "sees" my 48v battery as a partially discharged 52v battery. Are there any settings I have missed? In both my DCP 14 display setup, as well as my .el file setup directly to the controller, I am indicating a 48v battery. Drives me nuts!!!! @#$@@

Hi, I swapped my BBS02B for a BBSHD motor. When I fully charge my battery the display shows that it has 54.5v and is only 60% charged', when it goes down to 48v the motor cuts out. I didn't have any power issues with my BBS02B motor, I could get around 50km out of a battery, now Im lucky to get 10km out of a full charge. Do you have any Idea what would be causing my power issue?

Probably. Or you could try reprogramming it as described here
how do you test the controller, i just purchased a 1000w 52v, motora and it's not working at all, voltage going in but not getting out to the motor or any sensors, suspect the controller

The controller itself is potted so if it is completely dead then you may not be able to do much in the way of testing. That said, here is a link to our knowledgebase for troubleshooting
Hi Luna, I bought the BBS02 rev B from you in late 2017 and it ran fine over about 150 miles. In moving it to a newer bike, I believe I've damaged the controller caused by a short in the brake switch wiring between the 5V and Ground wires. The 5V supply is only driving 1.25V now. I need to replace the controller. I'd like to consider replacing the BBS02.B with the BBSHD.B controller and modify the firmware to limit current to 25A or less, thereby benefiting from the BBSHD controller's heavier-duty design and power efficiency. It looks visually like they are interchangeable with form factor and connectors. Is that the case? I'll be buying the programming cable with the replacement controller; I've been looking for a reason to order the cable anyway. Please advise. thank you, --steve bassett

Sorry the BBSHD controller is not a drop-in replacement for the BBS02 controller. If you wanted to upgrade to BBSHD from a BBS02 kit we do sell a bare BBSHD motor on the site which can make use of all the other components and save a decent chunk of change on the upgrade, but as far as using this controller on BBS02 that is not possible.
Hi Luna Cycle! Just wanted to ask how fast could you send 1 controller to Pennsylvania? Also, is the version 'B' made for 52V, 1000W, 30A motors? My controller has an additional wires for light and gear-cable power cut - will the version B suit me? Thanks!

Hi, if you select priority shipping at checkout we can ship it relatively fast, and we typically can ship this item within 2-3 day lead time once ordered. Yes version B works with 52v and yes it is 30A. This controller has wires for gearsensor, no wires for additional lights.

Hi I'd very much like to order a BBSHD 1000w Version B controller, howerver I'm unable to select that option on your website. I think there's something wrong with this order form. I have tried 4 different browsers, and I see for a split second the ability to select which version, then it immediately goes to a Choose your version * prompt. But I cannot get back to the radio option to select version B. Can you please help me out?

My Bafang motor works intermittently. Both PAS and throttle will stop working at the same time. From what I've read it may be the controller. The BBSHD 1000w motor was purchased from Luna Cycle last September. Invoice #63255. The controller appears to be a version B. Do you still stock Version B controllers? The website only has a version A selection. Do you think it may be the controller of other problem?

Hi there, could be the controller. You might want to check the Luna Knowledge Base for the troubleshooting guide. https://electricbike.com/forum/forum/knowledge-base/motors-and-kits/bbshd/39217-troubleshooting-the-bbshd-bbs02 Currently version B controllers are sold out but we should have some more likely in a few weeks or so.
