Bafang 3000 Watt BBSHD TorqueX Controller

[brothergc]

I was browsing today , and came across this

https://goldenmotor.bike/collections/bafang-controllers/products/bafang-3000-watt-bbshd-torquex-controller

Interesting to say the least . But I wonder because it seems to me that this would very much shorten the life of you motor .
Increasing from 1000w to 3000w OMG . You would be doing wheelies and putting some serious stress on the chain and derailleur

[brothergc]

I must admit that I have some interest in buying one of these and upgrading the nylon gear to a steel gear .
I have searched the web for feedback and from what I have seen , it is all positive .

I am interested in any feedback from people who have some mechanical knowledge as to any drawbacks of doing this upgrade . I am sure I can handle installing this seeing that I am a ex auto mechanic and have already replaced a controller on a BBHD before with complete success.

So any feedback will be appreciated !

[brothergc]

well I was already to order and they are out of stock :( So I settled for upgrading My Nylon Gear to a steel gear and added a lekie one nut .
At least I will have that out of the way when they do get these back in .

anyone interested in doing this it is not that hard , check this out

ok just got my new steel gear in and wow it is nice . Came with new snap rings and I am surprised by the weight considering its size . Here are some picks

[brothergc]

well that was a total flop . Got everything disassembled , swapped out the nylon gear for the steel one . And now I can hear the motor run , but no power to the wheels . Took off the steel chain ring gear cover and pulled the axle . I can see the pinion gear moving , BUT it is very weak meaning I can easily hold the pinion gear with my 2 fingers and stop it from rotating . Weird , any ideas ?
This motor is over 6 yrs old , so maybe some kind of mismatch ?

Edit I must have damaged the pinion gear in some fashion ? well out of time will update this Thursday when I have time to disassemble

[brothergc]

ok , I have a working theory , after browsing thru a few You Tube vids I found out that the nylon gear, or steel gear in my case is directional . As You can see from my picks the steel gear looks the same no matter which side I look at . I am betting that I have in installed upside down which would explain My problem . We will see ... stay tuned !

[brothergc]

Yep that was the problem , so always know the side of the bearing that has the arrow points downward or in other words goes in 1st so it is not visible . Live and learn ! LOL

[brothergc]

Ok , finally after a month they have these 3000 Watt BBSHD TorqueX Controllers back in stock , I just ordered one . I read all the reviews on Golden motor and they seem very favorable . So I ordered one .
My current battery can push 40 amps , not 50. So we will see how that works out .
In any case I post back once i get it installed !

[brothergc]

ok , I finally got this controller today , Golden motor was dragging their heals and took over a week to get it to me enen though their website said " In stock ready to ship"

Anyway , I got it installed and went for a short test ride . I can definitely tell the difference . Bike takes off like a rocket , way more torque , I would estimate a 25% increase . More torque in pedal assist in higher gears .
I do question the price VS performance ratio , seems overpriced IMO

I don't see much difference physically from the stock controller and everything fit perfectly . I will post more once I get to go for a real long test run .

anyone interested in this ? I post but it seems like i am posting a review to myself . :)

[brothergc]

Well went for a Test ride , at first all went well but very soon after pushing it to see what it would do , everything just shut down , some kind of icon showed up on my display . I then turned off the display and back on and it came back to life but stared acting weird long , intermittent delays when pedal assist would kick in , throttle not responding intermittently .
I have a Luna Black Box I bought years ago so I hooked that up and loaded Lunas' ludicrous profile . While in their I noticed no real difference in stock setting compared to a standard stock controller .
I suspect that this was a total waste of money .
I will try a 500c display to see if that is the issue , but I dought it

[brothergc]

well I stand corrected swapping out displays to my old 500c did the trick , pedal assist and throttle are back in business !
However I do notice a slight decrease in torque . Nothing drastic just slight , more even control . Which I welcome because before I was starting to pop wheelies , LOL Mow more refined and manageable control and still takes off like a bat out of hell .

[brothergc]

Ok, for my final entry , I just went on a long test drive . This bike rocks ! I can hold a steady 25mph in 5th gear with pedal assist and not even break a sweat . I can do 35 mph no problem . I am using a 30 amp ,17.5 , at 52 volts I would imagine that if I were to get a new battery that outputs 40 amps then all bets are off . Already in the bikes current configuration this thing takes off like a bat out of hell !
I do wonder why my 600C display burned up ? What I do remember is that on the 600c their is no option to set top speeds as where the 500c does .
So I will just stay with the 500c . I ordered a new one as these are getting hard to come by thru Jonney Nerdout web site .

So seeing all this I am open to comments , suggestions , or just a hello ! :)

It turn off probably because of the BMS overcurrent protection kicks in. You need to make sure your battery and your BMS can supply the amount of current the controller demands.

I would have to disagree , because if what You say is true then my 500C display should have burned up as well .
Here is My theory after thinking about it for awhile . I had the 600c display running the stock firmware settings of the Torque X controller . On my 1st test drive it acted all kind of crazy . I then loaded up My setting with My luna black box and chose the "Luna ludicrous profile" , changed the display to the 500c .
I believe the original settings of the controller is what caused the 600C to burn out .

[brothergc]

I find this interesting the the Bafang 3000w Torque X controller is no longer available on my last check of the website. Perhaps others have had issues ?

I'm thinking of doing this. Currently, I have a BBS02B CANBUS that fried the controller while climbing steep hills with an 11s and a Lekke 28T chainring. I'm trying to pull a heavy load, but I'm concerned it won't have enough torque to pull a deer myself and gear up hills. legality is my biggest concern. Oklahoma only allows 750W class 1 for hunting. I believe as long as I label the bike as such and adjust the parameters, I can still do it. Any advice before hitting the pay button on this? how is your set up so far? my other option was the CYC x1 pro gen4. But this setup is way cheaper i'd believe. I just bought an Eggrider V2 and an upgraded UART controller, hoping it will reduce heat and stress on the BBS02B. Any insight would help. Thanks

Luna used to sell a street legal BBSHD marked 750W. ( I have one). Resetting from 15A to 30A should do it. Or the TorqueX controller at 15A if you think they might check settings. For long uphill runs the BBSHD is the motor to have.
The TorqueX seems to be the 50A Shunt Mod discussed at Endless Sphere as a DIY project.
Moron this-
The BBSHD 60A shunt mod involves soldering additional low-resistance SMD 5 mOhm shunt resistors in parallel with the controller's existing stock shunts to lower the total resistance, thereby tricking the controller into allowing higher current draw.
Implementation Details
Resistor Specifications: Use 2512 size SMD resistors rated at 5 mOhm (often sourced from dead BMS boards).
Configuration:
45A Mod: Add one 5 mOhm resistor in parallel with the stock pair (reducing total resistance to ~1.67 mOhm).
60A Mod: Add two 5 mOhm resistors in parallel with the stock pair (reducing total resistance to 1.25 mOhm).
Hardware Requirements: This mod requires upgrading the MOSFETs to higher-rated units like the IRFB3077 (found in newer controllers or Luna Cycle kits), as the stock P75NF75s cannot safely handle 60A continuous current.

TBOK,
Your BBSO2 would not work with the Bafang 3000w controller , it is UART , and Yours is Canbus 2 very different protocols . But even so I do not believe a BBSO2 would handle the stress . Best bet would be to just buy a BBHD Uart and upgrade the controller from their
You can Just buy the bare motor from golden motor if Your interested
