Intelligent Brushless Sine Controller 36V 48V 60V 72V 84V 2000W Maximum Current 50A Aluminium Alloy E-Bike Brushless Motor Controller for Electric Bicycle Scooter

Everything is outstanding! I've encountered zero issues—installation was seamless, and programming couldn't have been easier. This new controller has transformed my scooter, making it remarkably faster and more responsive than the original. ⭐⭐⭐⭐⭐ I have absolutely no complaints! While I would appreciate more comprehensive documentation on some of the advanced features, like compatible displays, it's worth noting that the existing documentation is already superior to that of nearly every other vendors. ⭐️⭐️⭐️⭐️⭐️ This manufacturer truly stands out! Great quality, at a good price. ⭐️⭐️⭐️⭐️⭐️⭐️ Any bad reviews are more then likely user error / installation error. I've experienced no issues with mine after several months of torture. Even after damaging some wiring and letting a bunch of the pixies out of it, still solid and Rips.

The value and quality of this motor controller meet my expectations. I have a TST R9 ebike, and the OEM controller is so small that I am amazed it worked at all. This controller can handle a lot more than 1500W, so make sure your battery BMS is rated for at least 60A, or use a Y-connector to pair two 30A BMS batteries that are charged to within 0.1 V of each other.

Fardrivers are definitely the way to go, but if you want a serious bang for your buck then look no further! This is a FOC sinewave controller for under $50.....and it does 50 amps. It seriously punches way above its weight class. I would say it's a perfect controller for someone that is building a budget build or might not have a powerful battery like an Amorge and just wants to have a bike that has instant throttle response and can pop wheelies on demand. Works great for a Razor. There should be zero question at all buying this controller vs using the POS stock controllers like the Vevor for example with its horrendous and atrocious "soft start" extreme throttle lag delay. All thanks to the Male Karen's that complained to Vevor that their original controllers were too aggressive. Anyways none of that matters now because this little bundle of joy is 100x better than a stock vevor controller. I'm using it with a Caomm 52v20Ah battery that has a 50 amp BMS and a 2kW vevor motor wit stock Razor 25h 7.2 gearing and it'll pop wheelies all day effortlessly. Install was extremely easy you basically just have to hook up the 2 "learning" wires to each other and then give it throttle and it'll self learn and then its ready to rip!

Exceeded expectations sine wave worken with my 1000 hub motor perfectly made my bike faster considerably!! Still works great

stuck in 36v foc and no way to use my 72v battery. Self learn is broken, only works at 36v and other voltage causes cogging and cutoff,the self learning feature is broken and it is stuck in whatever it was set to at factory.

So I see this controller is labeled as “frequently retuned” and I can only assume it’s primarily errors on the part of the user.. I’ve purchased, installed and used many many brushless controllers over the years and am not sure what the issue people are having is bc while this is clearly no FarDriver it punches well above its weight class and for $50! I can’t say enough about it.. it’s almost as powerful as a Kunray 3000w and honestly performs up with $150-$200 FarDriver and Votol controllers although it has very few features as compared to those higher end companies. it does however pack a substantial punch for a 50A controller with all the more Standard features. Would have loved to see regen but hey it’s $50.. and I have yet to see any sub $100 controller support such a wide voltage range from 36v all the way up to 84v.. it’s relatively small for its output making it a great choice if space is limited.. I personally use a FarDriver 72680 on my bike and a Sabvoton 72300 on another and with all my higher expectations this controller really blew me away on a budget scooter controller swap I did.. I love this little guy and am considering just buying a couple more just to have bc I’m sure the price won’t stay at $50. I will admit the instructions have a lot to be desired so I wouldn’t recommend any of the Chinese controller if you have no experience installing them bc the wiring from company to company varies and there isn’t a lot of continuity in that respect so fir example green wire for this companies controller may not be the same for another.. and always remember when in doubt, don’t..

Good product overall except for 3 speed function not working. The controller is stuck on single speed (All speeds shorted to ground). On the controller that would be pink, grey, and black in big connector. All essential functions work properly.

I ordered a new motor and controller upgrade from Vevor for my sons MX 650 and once I replaced and installed new motor, controller and throttle; no power! Contacted Vevor and they refunded me for the controller. I used that refund to purchase this controller. I am glad I did. This was such a simple plug and play process with the Vevor cables and motor. Once I connected the battery and throttle the motor started to humm. I was stoked! The only issue with the controller is that it wont fit snugly without any modification. I ddint do any cutting or mods to the frame and just let the controller sit at an angle and zip tied it to the frame. Its not prretty but is effective. Overall I was super stoked that I had no troubleshooting to deal with, it worked on the first try, the color looks cool but cant be seen, the "smart" cable was easy to figure out, 1 page description of connections was easy to understand and it has a lot more connections for any future mods such as speed controller, lights, etc... GREAT CONTROLLER!
