Customer Reviews for VEVOR Electric Brushless DC Motor,72V 3000W Brushless Electric Motor,4900RPM Brushless Motor Kit,w/Controller and Throttle Grip for Electric Scooter E Bike Engine Motorcycle DIY Part Conversion Kit

The throttle as it comes has no real easy way to ease onto it. However I have no other complaints about the overall system very powerful lots of fun

Had installed 3 of them already on mx650 razor not much modification is needed only to remove motors 2 washers and put the bolts back on everything else is plug and play.

Nice motor, it came in fast and with all the proper equipment, cant wait to install it to my cart and see what it's got. But so far really good for the price!

5 ⭐️ Product! It is ridiculously powerful.. The only reason I only gave it a 4 is because It should come with a key switch to ensure only an adult rides it. I used it for a razor dirt bike build and it came out great. This thing will pop wheelies on you and I’m 220. It fits right into an MX 650 or a MX 500.Awesome engine great value. I’ve bought 2 in the last 3 months and both are working great! J.A.

Worked well to upgrade the motor on a razor electric dirt bike. Arrived on time and everything worked well. Happy customer!-SM

Updated 5/29/2020Talked to the manufacture who offered a reasonable solution to my issues with the 2nd kit; as such, due to customer service I'm increasing my overall rating to 4 stars.I have purchased a third motor kit and will be updating my review once it arrives and is installed.Update 5/26/2020My original purchase went so well and installed so easily that I ordered a second unit for my daughters MX500.Now I understand the challenges that some of the reviewers are experiencing.Controller:1st Order - all the wires were labeled, making the wiring very straight forward2nd Order - none of the wires were labeled and the colors of the wires were slightly different than my first orderMotor:1st Order- I was able to mount the motor will minimal modifications (cut-off the foot and sunk the screws that hit the frame)- Received mounting hardware that I didn't use but would have been handy in a different situation- Very simple modifications2nd Order- Foot was mounted incorrectly and I had to remove the entire thing just to clear the frame (much more work)- The mounting screw holes were also slightly off requiring further modification.- No mounting hardware was includedBoth kits had the same performance and I was able to make both kits work correctly.Manufacturer seems to have some quality control issues and it is the luck of the draw which version of the kit you will receive.I would still order the kit, but make sure you have some level of knowledge to make it work for your application.Original ReviewPurchased the Mophorn 1800W brushless motor kit as an upgrade for my sons MX650. The largest challenge was figuring out where to place the controller that wouldn't get in the way of the bikes operations. If you upgrade to lithium or lipo batteries this would help to eliminate the issue as the batteries would take up less space.Everything is very close to plug in play with the exception of the motor. You need to remove the motor mounting bracket which is easy as it is soft metal

My son is 13 and is interested in making anything/everything electric. He has taught himself so many things based on searching the internet and watching YouTube. He saved his own money to buy this motor so that he could make a traditional Power Wheels F-150 have more power (and surprise the neighbors). Well, this motor was great. He is a tall kid, so it's so it's funny watching this teenager roll around in a Power Wheels meant for a 4 year old. Now he needs to upgrade other parts in order for this to be a functioning vehicle (tires, battery, etc.) The motor is perfect and has everything he needs to make this function. I will post additional updates (and pics/videos) once he upgrades the frame/tires/etc.Thank you! AW and SW

I did test the unit and it does spin, no wiring diagram but there are images and tips on YT if you search brushless speed controller. You need to use a jumper or on/off switch on the connector marked "lock" I would also recommend using a 30 amp switch on the + side of the battery connector.

I made a custom mount to put this on a mountain bike. To be honest it's all rigged up and looks trashy, but I'm to blame for that. This is a really beefy motor that'll spin up real fast. However it's doesn't have a lot of torque. If your going to put this on something that propels a human(I assume you would), then your going to need a really low gear ratio to get moving. You'll loose a bit of top speed but this motor is so fast I wouldn't worry about it. I like that it has many optional wires on it for things such as lights, reverse, different speed levels, and more.

Thank you
