I just finished up my mx650 build vevor 2000w motor with a cheaper version of the Cozyel 48V - 72V 45A Speed Controller and a 15t front sprocket. Looking what to do next, Keep making the great content with easy to follow instructions on builds.
Im also building an mx500 out for my wife. But the only thing razor that'll remain about it is the frame, handlebar, and swingarm (even this will be modified). Its such a satisfying feeling to begin from scratch.
Wow. This came out really good. I was driving around and someone was throwing out a mx400. I have to diagnose whats wrong with it though, turns on but doesnt go. I do hear the control module click but i also need a charger. Cant wait to get started on it but might just do 48v, sell it and get a mx650.

@@PatOutdoors I just swapped the back tire to the left side to where I didn’t have to buy a gear box cause I’ve watched UA-cam videos about it and it’s easier to swap it than to buy a gear Box and probably will just have a front brake but I’m not sure yet
No. Often misunderstood, voltage has nothing to do with the motor. This is a 2000w motor that just happens to come with a 48v kit i started with before I changed the battery and controller to 72v. A more ideal motor with the set up is a 3,000w my1020 though

Question- has your motor last you cause my friend got that motor and burnt it up crispy but I was like 103 outside but idk if that was the cause but yeahhh
Hey sir I need to ask you some questions when you have time I did an upgrade like yours but on a smaller bike and it could be life dangering I just need some advice!
Motor and battery fully functional, just did a 50-mile ride with a video up a month ago. What is your friends rider weight? The Kelly speed controller should be beeping loud if it senses hot motor temp to prevent that from happening. I’m using the electro & co tune on my controller
Can you mount the my1020 motor on a razor mx350? Picked up the kit to convert my bicycle to electric but that failed, so I'm planning on getting a razor bike. The mx350's seem a lot cheaper used than the larger mx series dirtbikes. Awesome build btw.
Thanks! The MX350's can probably fit an MY1020, though you are working with a MUCH smaller bike with much more limited space for a decent size battery. Not to mention less space to put the controller and hid the wiring, etc, no suspension.
Does the light bar connected to your battery drain the battery quicker or do you see no difference? Looking to hard wire a light bar on my ebox but not sure if it will drain it that much quicker or use a separate battery for my light
19:18 - It's looking great man, let's just keep it that wa.... Nevermind, I guess we'll just say that this was tire clearancing. 🤫 *nonchalant whistling* 🙄 😂
I had to notch the motor mounts to slide the motor forward. I also ground the housing to make sure I have enough tire clearance when it expands when I'm cruising 45-50 MPH.
I'm guessing without a heat sink you're 100% going to smoke that motor, particularly without a temp sensor running a 14t (?) pinion. The heat sink from E&C is kind of pricy but well worth it.
Yes, likely will happen in the long run. I'm using a 13-tooth sprocket and the Kunray MY1020 has an internal fan and the end cap holes have all been drilled out for additional ventilation. Whenever it goes, I will simply just change out for the EC4P motor upgrade.
@@PatOutdoors I only got to 44 MPH (flat strip) with a 14 tooth, surprising you hit 50 on a 13t. I was riding for about an hour and fried the motor with that setup. Kelly controller from E&C, Kunray MY1020 72v 3000W, street tires on stock rims, stock rear sprocket. FYI the MY1020 motor has no internal fan. I know because I have taken one apart. The EC4P seems like a solid option. Wish it was available.
@@helicrashpro it actually has a lot to do with the overall diameter of my rear tire. I crammed a 10x3.5” rear tire (not recommended), so I get a slightly larger rolling distance from same motor RPM, slight cheat for top speed.
@@PatOutdoors I'm running a 10x3", it's crazy the 3.5 gives such a speed boost. Your tire video was really helpful and why I picked the 3" tire I got. Keep up the content.
Thanks! The KVD has an adjustable "max battery current" that is adjustable through the android app. I believe the standard setting from E&C is 33% to protect the battery. I just discovered this yesterday while I'm diagnosing my 52V bike build (which also has a 50 amp BMS) and finally got a bluetooth dongle. So far so good, but I'm likely turning it down a bit to protect the battery.
@Pat Outdoors thats what I assumed you could do with the controller and am greatful to hear it! I'm thinking of just trying to throw in a higher bms. Thank you for your response and guidance!
I’ve never heard of a 72 volt set up and a Kelly controller that goes that’s slow. What brand battery and controller do you have? What size front and rear sprocket? Tire size and driver weight?
Nope. I bought specific ones that have the exact same diameter hole. I did have to give up one washer on the outside to get enough threads on the original axle. Also had to have everything threaded together before installing the wheel and pegs back into the swing arm, major pain in the a$$
My first BTR battery failed after a month, but they sent me a new one through Amazon warranty claim. This second battery has held up over a year so far though. Power is limiting vs Amorge (better) batteries. I would maybe save up for better quality batteries if you can afford it and looking to build something really fast

@@juvenalgonzalez782 100A peak, usually means around 50A continuous. 45A rated Controller would be fine. A 33A controller would restrict the amount of power output though.

I did this build in stages since I was on a budget and couldn't afford a 72V battery and Kelly controller in the beginning. It was running with 48V in the past. I upgrade piece by piece till I got the speed I was targeting for educational purposes. I'm planning on replacing the motor with an 11KW EC4P motor anyway when this Kunray MY1020 eventually fails.
