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

Easy to install in the Razor MX650. Simply cut off the motor mounts, counter sink the end cap screws and it mounts in place of the original motor. The throttle is a bit sensitive but when twisted slowly it's manageable. Remember to connect the electronic lock or the motor won't operate. I used a loop of wire that I can remove for safety purposes.

So much torque I had to gear it higher. Quite and strong. This thing is fun wish I had more.

I bought this kit for my razor mx500 and powered it via 48v 20ah lithium ion battery pack and I'm pleased. The motor is very quiet, has decent torque and great top speed. Install was a bit of a hassle as I had to cut off the base plate and countersink 2 of the 3 screws holding the motor together so the motor would fit in the rear swing arm and then i had to reuse my old 11 tooth t25 sprocket but it wasn't too hard to do. One thing I've found is the throttle response is super sensitive which makes slow cruising a bit tricky but overall I have no complaints!

great kit for the price should probably get better bolts for the motor though

Kit has plenty of power! Running it on a pocket bike currently. Had to kneel on the foot pegs and lean over the handle bars a bit to keep the front down- I weight 225lbs Fun. Wear a helmet and other protective gear depending on the application. I may need to find something larger! Snappy off the line. Seller responded well and quickly to question/concern through amazon. Will try to remember to add picture or video later.

Around forty mph I like leaves other in the dyst

Was easy to install and fast with the right battery.just what I was looking for I'm going to get another one for My trike it's got the torque to move it no prob

First kit ordered actually had a bad wire inside motor. Customer service stepped right up. Installed kit. No wire diagram but very easy install. Just pay attention to how you take apart factory wiring. Everything is labeled. I just cut off original plugs and installed to new kit after cutting of unneeded plugs and used heat shrunk butt connectors. Studied up on YouTube videos. Easy install. So far working exactly as expected and posted.Update. With 9 and 11 tooth sprocket I can get up to 22.8. With 13 got up to 24.5. Just order 14 tooth sprocket. Not to bad for 220lbs. I even have my 4 yr daughter sit with me. Another 35lbs. I ride it to my local elementary school and can ride for a solid hr in some mild terrain. For price and ease of install cannot beat it. Ordered another kit to install on my sons go cart. Stay tuned.

To reverse the direction of the motor at full speed, keep the yellow thick wires connected but switch the blue and green thick wires. For the hall wires switch the blue and yellow wires.
