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. Review: Great unit - Bought a E dirtbike off of desertcart was advertised as a 500 W dirtbike top speed of 15 mph. The bike was slower than a razor MX 350 but appeared much larger so did some research. Bought this kit along with a lithium ion battery and the difference is amazing. I will try to upload a video for a comparison just to what the bike does now compared to a stock MX 350 razor this is not about insulting razor what so ever. The MX 350 is a excellent choice of bike for the money.It’s just a general comparison so you can see what the upgraded motor and lithium battery does to a E dirt bike ## Features - Kunray MY1020 Brushless Motor Features: Electric Brushless DC Motor, Aluminum Body, Full Copper Coil, Heat Resistant, Naturally Air Cooled, Low Noise，ensuring reliable speed even on challenging terrains and less energy consumption. - Motor Type: Brushless DC High Speed Motor, Voltage 48V, Power 2000W Max, Current 42A, Rated Speed 4300rpm/min, With T8F 11Teeth Sprocket Chainwheel. - About Controller: 48V 2000W 15 Mosfet 33A Brushless Motor Speed Controller, With Hall Sensor, E-Brake, 3Speed (Low Mid High Speed）, Reverse, Indicator Light And Power Lock Functions. - LCD Handlear Twist: 48V Lithium Battery LCD Screen Handlebar Throttle Twist Grips, With Power Indicator, Ignition Lock, Twist Throttle Accelerator 3 in 1 Function Handlebar Grip, With Rubber Grips。 - Application For: Electric Scooter, Motorcycle,Go Karts, Motorcycle, E Tricycle,Mid Drive Motor Kit, Complete Set,DIY Engine System, Cycling Part,And More.What You Get: 1pcs Motor, 1pcs Controler, 1pair Throttle, And Manual. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07G2LZHD8 | | Best Sellers Rank | #42,291 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #1 in Scooter Motors | | Brand Name | Kunray | | Customer Reviews | 4.1 4.1 out of 5 stars (217) | | Horsepower | 2000 Watts | | Included Components | 1pcs Motor, 1pcs Controler, 1pair Throttle | | Item Weight | 6 Kilograms | | Manufacturer | Kun ray | | Material Type | Aluminum | | Model | Motor：BY1020 Controller：BY15WF01-A | | Model Name | Controller：BY15WF01-A Motor：BY1020 | | Part Number | Kunray MY1020 | | Speed | 4300 RPM | | UPC | 734779299142 | | Unit Count | 1 Count | | Voltage | 48 Volts | | Wattage | 2000 watts | ## Product Details - **Brand:** Kunray - **Horsepower:** 2000 Watts - **Model Name:** Controller：BY15WF01-A Motor：BY1020 - **Speed:** 4300 RPM - **Voltage:** 48 Volts ## Images ![48V 2000W - Image 1](https://m.media-amazon.com/images/I/717XdGAID3L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: How fast will it go mph** A: Dear Friend, 1.The load speed is according to your wheel size , chainwhell teeth,and driver and scooter weight. 2.but I can tell you the speed how to Calculate: speed = bike wheel perimeter*RPM ( your chainwheel teeth /our motor 11teeth)*60/1000 3.our motor rpm is 4300rpm and use 11teeth sprocket. ex: IF YOU USE 64Teeth plate. so Gear Rato is : 64/11=5.8. so, rpm is4300/5.8= 740RPM. if you use for 8inch wheel. so the speed is : 0.2m(is wheel perimeter）*780*60/1000=28km/h about . **Q: This motor should be used only with lithium batteries? It does not work as lead, I have a brush motor scooter and it has lead batteries so the questio** A: I see no reason why this would not work with lead-acid batteries. I used it with a 48 volt, 1,000 watt power supply. **Q: ?Need to reverse the polarity to run the motor in reverse. I’ve switched a combination of two terminals, but still not getting the desired effect.** A: You need to switch the yellow, blue and green cables. These are the cables that control the motor direction. It is actually trial and error. This is the same as the front wheel motors. **Q: i bought a lithium ion battery with the xt60 connectors but this motor kit has rings. what do i do to change it?** A: Take out the fuse splice the wire to the type you want and Walla ## Customer Reviews ### ⭐⭐⭐⭐⭐ Initial Review *by R***O on January 29, 2019* 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.
