Tinkering23Hi I'm currently trying to do this same thing but I have questions. I already have my mx350 running 36volts with stock motor. Questions are can I run 48volts to the stock 350w motor? Also what 48v controller did u purchase and did you have to buy one that included a new throttle? I know that u can't use a 24v throttle in a 36v controller so thought I might need a new twist throttle with the new 48v controllers. If u could show me what parts you bought that be great. Also would u recommend getting a 48v 750 or 500watt instead of a 1000w motor so I don't have to change rear sprocket from to much torque from the 1000w like you did? Please email me email@example.com
adminTinkering23, You can try to run 48v through the factory motor and controller but it will most likely burn it up. I'm currently running a 36v kit that I purchased through ebay. You can find it by searching "Scooter 36 volt 800 watt motor, controller and throttle kit-Complete" in ebay. This setup comes with motor, throttle and controller and will definitely run 48v. If your looking for a more powerful setup I would suggest purchasing this kit from Golden Motor. It will get you up to 30mph + running 48v. Very spunky little motor and controller. I would strongly suggest purchasing the Golden Motor 48v throttle that is compatible with this kit. They work great!
adminhttp://goldenmotor.com - Click on BLDC Motor and scroll down till you see the 1500W BLDC Motor and 2000W BLDC Controller. They also have throttles that will work with this setup. Either way you go, you will most likely have to change the sprockets to reach desired torque. It's worth a try with your current sprocket on the rear but the standard Razor front sprocket will not fit either of the two motors that I've suggested. I would suggest going with the smallest front sprocket that you can get for either of these since the RPM is so high. I'm currently running a 7 tooth sprocket on the front.
