    • 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

Have not used yet . Instructions has phase connector and junction box. Instructional Video also has junction box (5) also. Nothing was included so I had to order from elsewhere cost me another 10 bucks. Update: for those of u whole need to reverse the motor rotation its not bad From the esc hall connector : Splice and connect blue to yellow and yellow to blue. These are 18 gauge thin wires. Picture included From the motor big azz cables yellow to yellow, blue to green Final Update: The phase wires were REALLY hot but this was my own fault as I connected with nut and bolkt. make sure to have a very good connection or you will have resistance =HEAT. At the end I spliced them together with a wire nut which removed the issue. I was worried that the phase wires from the motor were much larger gauge but turned out to be User Error . Motor: I hooked this up on a monster motoE1000 with a 48v 20 AH LifeP04 Battery ( This thing absolutely rips! Im 6ft 235 and I top out around 28 MPH on grass. I rode this next to a Juiced Bike with MPH gauge against my son (125 lb) and we were neck and neck. So far so good, no heat issues, battery is till running strong, seems solid so far. enjoy! ... show more

    • Case casting broke.
On my mx500 this motor’s mount broke clean off on the sprocket side. The casting is too weak. Motor runs great and has good power. Real shame that it broke after only about 10 miles and just a few days outside of return.

    • exactly what I want
Size: 48V 1600W Style: 48V 1600W
this is the second one I have bought and I've been beating on them. I've had one for about 6 months and it's going just as strong as the day I got it and I've had the other one for about a month and it's still doing good.

    • Razor EcoSmart Metro Scooter
Size: Large Style: 48V 2000W 45A motor kit
I bought a razor ecosmart metro scooter and upgraded it to 48 volts getting it up to 21mph but over 400 miles I burned out the original motor due to my weight and the extra voltage. So I bought this motor and controller kit for it. I had to drill new holes to mount the motor and install an extra box to house the controller and one of the four 15 Amp hour batteries I bought. You also had to reverse the rotation of the motor by swapping the thick blue and green wires and swapping the tiny blue and yellow wires going to the motor cable. After all that it goes about 16 mph in low, 23mph in medium and 32 mph in high speed. The whole system works great and I'm very glad I purchased it and would recommend it to anyone looking to get extra speed and power out of their scooter. ... show more

I had an issue with the motor, it seemed to stop working. I contacted them and they responded quickly and helped me out. They sent me a complete new kit at no cost. Great customer service. Will buy again.
