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 3/6/2019 Added 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. ... show more

    • Works as described, arrived quickly, in good condition
Size: 48V 2000W Style: 48V 2000W
I knocked a star off mainly because they don't seem to provide any real documentation, and keep referring people to their Amazon listing for instruction. At this price I didn't expect a lot, but it is working exactly as they described. The wires have mating connectors except for power to the motors or from the batteries. Connectors were all labeled as well. In my build reverse seems to be about 1/2 to 1/3 the power of fwd, and I am checking with the vendor to see if that can be altered. I am using it to power a small sailboat inboard prop shaft. ... show more

    • Not worth the price, get a better controller and throttle and find a better motor.
Size: Large Style: 48V 2000W 45A motor kit
I bought this kit to upgrade my son's electric dirt bike, an SSR SRZ800. I have learned several valuable lessons from this purchase. 1) the controller is huge for a 45 amp unit, it is absolutely monsterous and was going to be really challenging to fit my application. 2) the controller is soft-start, which doesn't work for a fun dirt bike. 3) the controller is not programmable in any way. 4) The motor is horrible quality, unbalanced, and doesn't go to max rpm. This kit would earn a much better rating from me if there was an ability to program the controller and adjust parameters like direction, soft-start, peak amps, and speeds. So essentially the controller isn't a great value. Now the motor: The motor vibrated a lot and wouldn't run correctly. I tried a better Kelly Controller and it would run up, shut off, and run up again with a hall sensor error. The motor was trying to vibrate off my bench. I took it apart and it was horribly unbalanced. All of these MY1020 motors are made to a price point, but the one I got was garbage. You are much better off sourcing a motor directly and then buying a Kelly or other programmable controller and the throttle separately, it will be cheaper and better. ... show more

    • Good motor and controller
Size: Large Style: 48V 2000W 45A motor kit
The media could not be loaded. Well built on motor/controller. I was having issue but it was my fault. I have figured it out and everything is working correctly. But if you need any support. There is no phone number to call. Contact Kunray via Amazon messaging only and is useless. 6/28/2020 . Top out 41mph on a go kart. Love the sound of this motor. Total weight is about 300bls with driver. PS. A note for those people complaints about the motor/controller. The motor in default is only run on Medium speed @ 80% power. In order to run the motor at 100% full power. You will need to have a speed controller install ( cost $10 on ebay) 1= low @60% power 2= Medium 80% power 3= high 100% power. The motor in default is a soft start controller. To get hard start, you must connect the 2 whites wires together to activate hard start. As of 8/20/21 the kit is still running strong running on maximum voltage of 57 -58 volts battery from the 48v battery source. Most 48v battery fully charged is 54 volts. ... show more

Tossed(gave away) the new stinky, oily, hot, noisy, gasoline(benzine is poison) fueled engine for this little gizmo. Please note, I’m 280 lbs, this little motor takes me everywhere I’ve wanted to go. The way it’s geared(11.1 to 1) takes me to 26.5 mph by GPS. I use my 48v 20ah EBike batteries with both 30 and 50amp BMS. Been 4 months now, wore out the first set of tires. Constantly asked if I’ll sell my little electric mini bike, I tell them I’ll show them how to build one for themselves. Please note: Instructions are next to nothing(fire starting material), no customer support. If you do buy this, test it asap, if it doesn’t work send it back. Lots of info on YouTube and ElectricScooterParts dot Com. ... show more
