Used to convert a mini bike to electric. So far it has been working amazing. No issues with power or speed. It was fairly straight forward with pairing with the associated app to tune the controller. Built in bluetooth works as expected, just make sure that you have your location and nearby device sensors turned on, on your phone. I typically keep my location sensor turned off on my phone and I had a heck of a time troubleshooting why the app was not connecting to the controller. Other than that everything else has been fairly seamless.

Would not recommend I bought this and put this on my razor SX 500 and after 2 1/2 months, I am melted the motor with the stock tune it’s also slow with the tune I had with a 11 tooth front sprocket and a 60 rear with a 35 chain with a 10 inch rim, I only hit 40 mph and The side bolts on the motor covers strip out way too easy. I had to tap mine to a 10 mm bolt and for the same price of this kit you can get a FarDriver ND 72 450 with a electro and Co. One brushless motor. And a surron throttle and grips and a three speed switch and a key ignition with voltmeter. And in total, you can push 14 1/2 kW with a max or RPM of 7 1/2 related 9 1/2 max and you can go 60 to 65 for only 400 to 450 bucks and you can buy a kit that’s plug-in play and you get really good customer service so yeah would not recommend this kit what instead of getting this kit you should get this FarDriver 72 450 from E iconic cycles with their farDriver wiring kit, it comes with a throttle three speed switch voltmeter with key ignition and it’s all plug-in play And for the motor get a electro and Co. One brushless motor.

Perfect fit for the Razor MX650. Don't forget to buy the Fardriver mount.
