Electric Brushless DC Motor Complete Kit, 48V 2000W 4300RPM High Speed Motor, With 33A 15 Mosfet Controller, Battery Display LCD Throttle, Electric Scooter Bicycle Motorcycle Mid Drive Motor, DIY Part

Easy to install! Install book very helpful. Very well built. Had to reverse direction of the motor. Great price. Just what I needed for the upgrade. Thanks for making it painless. Love it.

The media could not be loaded. I have only received the motor/controller and am in the process of installing this system but it is being put in my own design so it will take a while for a comprehensive review. for now, I thought I would do the review on what I know.The motor and controller came in protective foam wrapping and box adequate for shipping. While there are nicks/scratches on the motor just like the product description states. these are cosmetic and are not going to affect the performance. If it bothers you the motor is nicely polished and a simple buffing can resolve it.I wish they had included mating connectors for everything. These are not STD that I can tell so for my project I will have to cut the ends and remark the cables and would surely void any warranty on the controller. Having mating connectors can prevent that.Once I have my project completed I an probably help supply a schematic that most people may be interested in using. What is odd the brake light and indicator light both show 48V output. That is a high voltage for lights, normal LED/lights for vehicles are 12V so will interesting to see if I can find lights or a way to step that down. Also, it is not clear if that changes to 60V if the SM 48V/60V wire is connected.Also, there is a reversing signal pigtail. Not clear how that is setup, but I assume a simple NO connection will do.I will edit this post as I find out more things, but for now the motor/controller was as expected.EDIT 3/6/2019Added 2 photos and a video. I am building an Electric mower and using this motor to power. While some will say it is under powered for the job. I intend to show that most electric conversions have been grossly over powering the electric motor. You really do not need that much.First a image of the original mower, had a 18-20hp Twin Cylinder engine that I got after a son drained the oil but had no replacement oil and left with friends. Dad came home and mower yard and burnt engine up. Chassis is in perfect shape.The video shows a test spin, with no load. It was running about 1/4 throttle. As you can see the chain was loose so I did not run it fast. I am working on a chain tension system and better motor mounting. Again, this was only a test.The third picture shows where I made my mistake of only using the bottom mounts, When I put the wheels on the ground the motor and torque literally bent the motor mount. Fixable though.Some points on my setup:1. I am currently running my mower on (2) 24V - 2ah electric drill batteries connected in series. Once I get the motor mounted and wired I will build a more appropriate battery stack.2. REVERSE: For reverse all that is needed is to wire a flip switch into the connector. When flipped turning the throttle gives you reverse. It is that simple.That is it for now. Next steps are to look into the braking system and brake lights, ect. Since there are no opposing connectors, I have to replace and rewire all of the connections.Someone asked a question about the throttle graph not working. It DOES. But you have to provide over 42V. If not, it will only display the battery symbol and bottom bar of power. That is the indication that the battery is dead.I am also planning to provide a complete set of plans on using this motor for a conversion if anyone is interested.

I should start this off by saying that I am limited in my practical knowledge regarding electric motors and controllers. so instead of trying to piece a kit together, I bought this kit, after some difficulty with the battery supplier regarding a charger, I finally got to test my setup (custom bike). Worked like a charm with no load... until I tried to ride it. Hopped on put it to 3 and eased er into it, notice. tried 1 and 2 still nothing. maybe its my gear ratio so i bought another gear and tried it again. It moved!!!! not more than walking speed no matter the phase level. Got maybe 200 feet before everything stopped working. Key on-off nothing. turns out walking speed overheats the controller so that's cool. Just don't do it save your money get a real kit that doesn't overheat its self. now i have 300$ worth of trash.

Got the quad up to 15 mph, stock was 7mphTwice as fast for not much money tbhTwo issues I encountered.I had to mess with the phase wires and hall sensor wires (motor was spinning in reverse) which instructions said that could happen. However instructions did not say which wires to switch but with only a few wires I tested all variations and settled on the one that worked.The 3 speed switch had 1 slow 2 fast 3 fastThe plug for reveres was not used. So I had to take out the wire from the reverse plug and add it to the 3 speed switch plug to get the desired 1 slow 2 fast 3 reveresOther than that seems like decent kit and good value for the money

Ended up putting this setup in my mini bike and it works great! I needed a new sprocket to match my existing #35 chain (the one it came with isn't the correct pitch). For reference it's a dual d bore or double d bore where its flat on 2 sides and rounded on the other. I also had to switch the direction of the motor to clockwise in order to work in my setup. There's other reviews mentioning this and a video you can find online. It consists on switching 2 motor wires and switching 2 of the motor phase wires. With a 10T front and 75T rear, I'm getting about a 23-25mph top speed. I'm also using a 48v 13.5ah battery and getting about 30-60 minutes of run time depending on the environment.

i bought this to help my Razor MX650 pull me along! i’m a 200lbs man and the stock motor just had enough power to get me going! it would not be able to pull me on the slightest incline! this 48volt/2000w motor is a huge upgrade! i can ride the razor up inclines and able to get to 20mph! very happy with this!

The motor is great. Barely even gets warm, but the controller seems to be under powered for the motor. I installed this setup on a drift trike (upgraded the Razor Drift). It works really well and has tons of power (i'm 200 pounds). The only issue is that the controller gets so hot after about 20 minutes of use that the wires will melt if I don;t stop and let it cool down. The casing of the controller gets too hot to touch. I've tried replacing the wiring from the motor to the controller, but that doesn't help. The only possible outcome is that the controller is under powered for this application.
