This Ebike motor kit is very easy to install andPreforms well. I’d get the heat sink for the motor since it could get hot when using on steep hills.The wiring diagram was very intuitive and easy to follow. It’s geared a bit high so it’s great for speed 50mph + but you should get a lower gear ratio for off road. I had to counter sink 2 of theMotor bolts to make flush for mounting on the Razor MX650.Everything else was very easy to retrofit and worked well.I would recommend this kit for anyone who wants to upgrade their Ebike or MX motorcycle

I bought this motor for my son's MX650. It almost fit without modification. I had to drill the holes for the screws a bit so the screws would counter sink. It was very easy. This motor is a beast on my son's MX650. I put 1 size larger front sprocket on it. OIt'll do about 60mph.Great little motor, and bundle for the price.One more thing, this seller has other motors. I first looked at one with more feedback on it, but it was for a go-cart type of set up with a mount on it.I asked the seller about a motor for a Razor. They directedd me to this motor so i don;t have to cut the mount off.Very responsive and fast seller.

I used this kit to convert a Razor MX650 to 72 volts. Everything fit with only minor modification. The controller fit nicely where the fake gas tank used to go. Nice kit for the money
