MOTOTPR Brushed DC Electric Motor 36V 800W for Quad Trike Go-Kart Scooter ATV Moped Bike DIY

I had a 48v conversion done on my son's quad razor 500 and the razor motor burned on me twice, so I changed it with this one and so far it's been good. It's not a direct bolt on and you will need to drill new wholes for it and new sprockets. With this set up my son 75lbs is hitting 20mph all day long. Its a T8F chain with a 54 tooth sprocket and a 9 tooth pinion. Which makes it a 6 to 1 ratio. Update one year later 08/2023, this motor has bean a beast. Its been carrying me as well, (230lbs) up decent hills without complaining too much and its not overheating or anything. Good Luck

I'm 180 lbs and my razor pocket mod 350W motor burnt possibly due to my weight. I upgraded to this motor, and needs some additional mods to position the motor correctly and line up the chain, as well as a 40V HART battery. But it's all worth it, afterwards, the razor scooter rides so fast, and I'm addicted to it. Don't wanna go to 1000W, that can be too fast.

Big improvement over the 350W stock motor on my sons Razor mx350. *(previously upgraded the battery and controller) Mounting was a complete PIA. dont have a tig or mig welder so bolting Alu angle brackets together was quite tricky given the tight space you have to work with. With stock gearing not sure if the top end is much higher then 20mph but the torque difference is significant.

Good strong motor with lots of power. I purchased it and many others for power wheels I built for my two boys, this motor with the set up I had was good for 27mph with myself(175lbs) riding it. No instructions but still very easy to set up with my pieced together kit.

It was perfect for the razor mx350 with some modifications to the mounting plate on the razor

Great 😃👍 products put this on my MX350 razor and wow " 🤯 was it fun had a blast will buy again if ever needed another one

Great motor for my son’s MX650. Only downside is I had the cut of the mounting wings on it. But that wasn’t a huge deal breaking for me considering the quality of the product.

3 months later still working great. Perfect fit.
