Brushless DC Motor 3000W 72V Electric Motor High Power Brushless Controller 50A Scooter Motor Go Kart Electric Motor Kit

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.

No customer service options through Amazon for troubleshooting this product.Bought last year and put around realistically 50 miles on it before it started knocking and making a loud noise.These things aren't cheap and pretty sure I'm stuck with a motor that's going to break soon as it gradually gets louder by the week.Definitely don't recommend for anyone. Purchase a FW11 or QS motor. They're more expensive but you'll be 100 times happier in the end.If these things break you are on your own.

The media could not be loaded. Bought two of these to mod our Razor 500's. We're running the 72v, 25ah 50A batteries with it and they ROCK! We had 48 mph with this setup. So fast that I took the High speed off my son's bike; it's just too fast for a teenager. Straight forward Plug And Play. Nothing weird or strange. Throttles "could" be made better/stronger than they are (broke one already-three weeks in) but replacements are super cheap and easily available on Amazon. This kit is NOT for little kids, with the gearing it wants to wheelie right off the bat. Sit forward and hang on. Would like to know from the Seller what type of chain they send with the kit; I need a 1/2 link to properly tension my chain since it stretched a little. Taking out a whole link is too much so I need a 1/2 link, but don't know which one to buy for it.

Bought for sx500 has been flawlessTheir is modifications that need to be doneCounter sink, the three bolt heads sticking out of the side of the motor. Also drill out all of the holes in the side plates to much larger diameter to dissipate heat.

So far it's been installed for 3 days and now the throttle is sticking full throttle. Not sure how to feel yet

Motor and controller work awesome, love it! Well worth the cash

Terrible product. Does not work! Do not buy this! Save yourself the stress.
