VEVOR 2000W Electric Brushless DC Motor Kit - 48V 4300rpm Motor with Upgraded Speed Controller and Throttle Grip Kit for Go Karts E-Bike Motorcycle Scooter DIY

Its Great! Super powerful and lots of fun on my little go cart. great for the kids to ride, defiantly recommend the speed control switch. Great value for the cost. The welds look a little weak, but we'll see how long it holds on.

Comes with t8F sprockets, 2 of them for the drive shaft on the motor. I am using this to power my mobility scooter. It has great control, doesn't get hot, and works great. BUT...It is a slow start. Top speed with the 11 tooth drive, and a 28 tooth driven sprockets driving 10 in wheels is still 28mph. But, no torque. I'm gonna have to gear it way down , so it will have more power for hills. All in all, a good value. I don't see this powering a bicycle. A go cart, for sure. And going almost 30mph on a mobility scooter is kinda nuts, too. My old motor only got me 15 mph, but It would do wheelies for a block. No way this is 2000 watts, but the price reflects that. My old motor was 800 dollars, but it lasted 10 years. UPDATE: I got a 54 tooth sprocket for the drive wheels. Still does 25 mph on speed three, 7mph, on speed one, and 15mph on speed two. I can now go right across grass, and do wheelies!

I had a battle with myself on the review. And wish I could give it 5 stars. OK. The motor is absolutely wonderful! 1800 watts Powered by any 48 volt lithium battery, The motor over achieves! Top speed on speed 3 Is 33 miles an hour carrying 130lbs. Connections were well put together and easy enough To attach To make motor run. I installed this on a razor MX500 Where a bunch of modifications had to be made. I had to recess 2 bolts On the motor to make it fit. And I had to take the old sprocket off of the old 500 watt motor and fit it on to the 1800 watt motor To fit the chain. Which was easy enough. The cons: The switches! 3 speed switch Is cheaply built. I suggest buying an aftermarket 3 speed switch to fit as this 1 only 2 settings work Consistently But can be finagled to make all 3 work. 3 speed switch is also too small! It was terrifying trying to mount it Without the wires coming off of the switch. Throttle that came with the kit is cheap! Very hesitant When turned Takes forever to engage the motor. This is why I rated it 4 stars instead of 5 And I hope nobody takes offense. Just an honest review from a guy who never did anything like this before when it comes to electric Kits. And for a cheap MX500 build this is definitely the way to go! Just get a new hand throttle And a new 3 speed switch.

I received the motor and controller and the wiring was labeled. The only wiring problem was with other suppliers. The 3 speed twist throttle with a volt meter was the hardest. I put a brake/taillight with a brake on the handlebar, a key switch, and a 48v 35ah lithium battery. I installed it on a Rhoades Car. The buggy weighs 200# with the motor, battery, and case. I weigh 185# dressed and my wife is about 130#. When I wired and tested the motor, in third, it did not run smoothly. In first it was fine, in second it was OK, but in third it chattered. I contacted the seller and never received a reply. After installing it on the buggy, I found that when starting out with just me onboard the motor chatters in grass. On a smooth, level surface, it is better. With both of us, we have to get started with the pedals and then the motor kicks in. It could be too much weight for the little motor to start it. Once going, it is smooth and propels 525# down the road. It will hit at least 20 mph but the cycle car is not built to go that swiftly. About 8-9mph is just right. The motor does get hot to the touch after 5 miles. I have been trying to get information from the seller but no reply. My rating would may have been higher it the seller would respond. I want to know if it will damage the motor when it chatters.

Used this for a go-kart project and it's a great little motor for the job. Driving around for 10 minutes barely gets the motor warm, so it's got plenty of power for a go kart (can get my kart up to 25mph at top speed). It has good low end torque for a fast take-off, and even with an extra hundred pounds (my kid in the passenger seat) the motor barely noticed a difference and still had pretty much the same power. My setup is a 6:1 gear ratio (60 teeth on the wheel sprocket, 10 teeth on the motor sprocket). Connections were easy to make, and like others have said, the "electric lock" connector is what you should use to wire up an on/off switch. Reverse works well, but be aware that it does not go full speed just in reverse. If you are like me and needed to switch the direction of the motor (without using reverse), here are the instructions I found (from leafmotor blog) that worked for this motor/controller setup: For the 3 larger wires coming from the motor, you will want to wire them to the controller like this: Motor ——– Controller Thick yellow wire ——- Thick green wire Thick green wire ——- Thick yellow wire Thick blue wire ——– Thick blue wire For the 5 smaller wires coming from the motor (hall effect sensor) you will want to wire them like this: Motor hall ——– Controller hall Thin yellow wire ——– Thin yellow wire Thin green wire ——– Thin blue wire Thin blue wire ——– Thin green wire Thin red wire ——– Thin red wire Thin black wire ——– Thin black wire For the hall effect wires, it's pretty easy to use a tiny flathead screwdriver and pop the connectors out of the harness and swap the blue and green wires.

Amazing I had put this motor on my mx350 with some modifications and I had went between 30-40mph the controller is light weight and compact to put in. Small spaces and thus is probably the best kit I've bought for my bike it came with all the bolts I needed and the wench was VERY USEFUL for the bolts the throttle had a very nice soft feeling the only thing that I would recommend getting is a better throttle because the one that's included has a slow response rate so I had got a different throttle made me go 0-30 in 8secs Amazing product for the price and great for starters

The backstory: So about a year ago I found a Razor MX500 pocket bike in a dumpster. It didn't look like it was in horrible condition, so I brought it home and after replacing the dead, stock batteries with a lithium pack built from 2001 Macbook batteries, found it was just fine. Tires held air just fine, and after a bit of WD-40 and some chain oil, the chain was fine. Brakes, everything was fine other than some cosmetic issues. After a few rides one of the cells shorted out and I shelved the project until I could get some funds to really go all out. Over the last year I've been buying used packs from a local e-recycler. One day he stoked me out, and sold me 17 9 cell HP packs new in box. I still have to rip them apart, charge em, test individual cell capacities, and mate it to a BMS controller I have sitting here on my desk. This will give me a 13s 11p pack, but enough of the backstory. I had been browsing amazon for some time looking for a full on replacement like this when I came across the Mophorn. For months I waited for summer to roll around (I have tuition to pay the rest of the year) Finally my day came, and I ordered the set, the BMS, everything else. First impressions: The motor is built well enough. The sprocket on the shaft of the Razor and the Mophorn are toothed differently, but the Razor sprocket fits on the Mophorn motor without issue (The bolt holding them on is reverse threaded) The motor itself seems to be built from Aluminum. The magnets inside are really strong, it took some force to spin this thing by hand. The bolt hole patterns for mounting the motor are identical to the stock MX500 motor. It even accepts the same mounting screws. The Bad, not that bad but could be better designed: I wasn't able to get the motor mounted tonight for 2 reasons. 1, the welded on motor mount on the bottom hits up against the MX500 frame in a way that it just won't allow the holes to align. Flipping the motor around, the wires coming out of the motor exit right where the frame is, preventing mounting in that direction. It would be nice if this mounting bracket was either removable, or if there was another model without it. Further compounding it is the screw types used to hold the motor together. You have round head screws, which even if the welded motor mount wasn't there, these would still prevent you from mounting the motor on an MX500. A better choice would have been either a flat head screw, or a recessed screw like the MX500's original brushed motor has. Final Verdict: Too soon to say. None of these are issues I can't work around. I can grind off that motor mount, I can find replacement flat head screws. Once those issues have been worked out, and I have the battery pack built, I can give this a final review. Just thought it might be helpful for anyone looking to do the same Razor MX500 mod I'm attempting to know ahead of time what to look for. I

Amazing value Installed two of these on Razor bikes Follow you tube instructions, not plug and play as far as the motor mounting you need to grind off the bracket and countersink the long bolts and grind off the excess ends. The controller has been upgraded and has more take off than last years model. Big improvement- can wheelie without the shunt mod. Super cheap 48v upgrade and get 23mph on mx650, sx500
