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

Shipped very good. Great kit for beginners. Very fast and functional, and great value for you money

Fit this into a razor mx650 paired with a 48v battery and the top speed and torque multiplied by 3x… when I had the bike it felt was more snappy and had a high top speed (35-40ish mph) Although I don’t have my razor anymore I recommend this brand to anyone who’s wanting to either upgrade motor or just swap out for a new better lasting one 👌

I recently purchased the VEVOR 1800W kit for an electric vehicle project, and overall, it’s a solid starter kit with a few caveats. Right out of the box, the motor arrived banged up with noticeable scratches and a slightly bent output shaft. While the damage didn’t affect drivability, it was disappointing to see for a brand-new product. That said, the kit’s performance was impressive. The controller, equipped with a SMOOTH START feature, delivered a very slow but responsive ride, which exceeded my expectations for a stock setup. I was planning to upgrade to a VESC-based controller anyway, so the controller having smooth start didn’t deter me. The kit’s wiring was a highlight—super straightforward and clearly labeled, making installation a breeze even for a beginner. Despite the motor’s rough condition, the kit’s affordability and solid performance make it a great entry-level option. I’d still buy it again for a budget-friendly starting point, especially if you’re planning to upgrade components later. It’s not perfect, but it gets the job done well. 4 stars for the banged up motor

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!

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

Frankly, I am having one very big problem, already, and I have not even been able to install this thing, yet: The sprocket is too small for what I am doing, and I cannot even get the nut/washer/sprocket off to add a more appropriate size already on-hand. I have tried time and again to do this, and instead, it seems that it was put together so tightly (via a machine) that, instead of being able to do what I need for the sprocket, the nut & bolt are suddenly completely stripped (the nut will turn constantly, but it WILL NOT come off. which means that THIS thing is NOT built to be repaired or altered. And this is just for a basic and necessary modification. Overall, from what I am noting, right now, This was a complete waste of money.

It is a pretty good beginner kit, but it's very delayed and sometimes does not use the correct power that it is able to use. Pretty easy setup, just screwing the motor phase wires to the controller is pretty difficult.

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
