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

I got two of these kits and outside of the sprocket you connect the other end of the chain to all you need is a battery and some imagination. I got everything they said and in great shape really surprised what all you get for the money!

No complaints. Put it on my razor sx500 with a 48 volt 20 ah lithium bank and I’m going 25mph.

Easy to order, prompt shipping, it looks nice. I will have to update this review once I get installed and tested.

This kit is very easy to use. The only thing is that some of the plug labels are in Chinese , but if you follow the wiring diagram it’s easy to figure out. Oh and if you get this kit, make sure you get a 72v battery with at least 45ah continuous, not peak. It will cost you, but you will be happy you spent the money on that battery, trust me.

put this kit on my razor ecosmart scooter. i made a 48v 20ah lithium battery for it. i get about 33mph top speed and a 40mile range.(range will depend on your battery). i have put a few hundred miles on it with no problems at all. i had to use the old sprocket from my old motor, the one that came with the kit was for a different chain size. i also ordered a new sprocket with a few more teeth in hopes of higher top speed but it really made no difference at all. it was actually slightly slower. the throttle is very touchy at take off, you do get used to it but i would prefer something smoother. i think a different throttle might fix this as this one the speeds are just so close together its like full throttle at take off, but if twist the throttle very very slowly and your on a smooth surface you can take off slowly. that's why i think it has more to do with the throttle than anything else. i haven't tried replacing it as i am used to it now and its not that bad. all in all great kit and good price. the big cost is the battery. to me it was worth it as it really made this scooter much more fun to ride and the range is 3x stock and it goes up hills with no struggle at all.

Good budget build kit for a razor. Got 30mph with the stock gearing. Easy to loop as the throttle is kinda touchy. Running a 48v 20ah lipo

put this on a home made 6 seater bike/cart reduced thru 2 jack shafts will move 6 adults easily (still in testing stage) using 4 -12 volt auto batteries average total weight 1100 lbs powerful set up

Using it on my mini electric kart.Hitting 26 mph with 9 tooth front and 56 tooth rear.Definitely can't use the f/n/r switch since there is no connection for it.

Best deal out there for ebikes, quads, dirtbikes. A Must have to increase speed or just because your bike slows down on hills or because of rider weight

Bought these kits for some mx razor dirtbikes, work great. Very little needed to do to get them installed. Very quick vs the stock setup
