Want a crazy power house for the second stage of your bike? This is it. Loads of torque to carry that front end in the air and plenty of speed to keep you going. If your coming from an my1020 motor I’d suggest you have some handle bar grips you can keep a hold of lol.

The motor worked great at first......it ran great while testing without a load. Once a load was put on it the hall sensor faulted and the motor no longer runs. we are out of the return window. 200$ wasted. Buyers please beware

Unfortunately it looks like metal in sprockets had defect and it broke a half within first 5 minutes while bike was on the stand (not even on the road). I guess this is not something quality control can really catch. I will update review after learn how good customer service is and how fast replacement part will arrive. Update. I am changing my rating from one star to three because seller’s customer service so far is very responsive. After exchanging couple pictures they told me that replacement sprockets is on the way to me. No tracking number yet, but so far I have no reasons not to trust them. I will update my review when replacement sprockets will arrive and I will be able to test my upgraded Razor 550. Update. Kunray support is pretty good. It took probably 3 weeks, but I received two replacement sprockets and two nuts. I fixed motor and so far everything works perfectly. Updating to 5 starts since issue is not really theirs and they did their best to fix it. By the way, Razor 550 with this motor was able to do at least 40 miles per hour. It probably can go faster, but it was pretty scary at this speed on this bike. One suggestion - during upgrade you need to remove original chain tensioner because new chain is larger and at the spot which has lock it may cause ssafety issues. I didn't yet removed tensioner, but planning to do it during this weekend.

it is a very powerful motor. I will give it that, but the motor came with no mounting holes that were compatible with razor the thread for the front sprocket stripped completely when I took the bolt off.

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.

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!

Easy to assemble and great tutorial for setup but the controller has a very slow start with high power band. I would love to overwrite this but not programable. This leaves product to be an ok product.
