35 MPH Razor MX500 or MX650 for $420 - Tesla Inspired Dirt Bike 

This is the best tutorial video i ever saw. i watched so many and they skipped the 2 steps you showed. THANK YOU.

subscribed for giving us something short, sweet, into detail and a cheap alternative.

Thanks Rich! you are single handedly helping me make decisions to get a bike And on the road! For Best Bang for my buck!

Wow, i’ve been looking for a tutorial for ever to help me because i’m new to this stuff, thank you so much!

Thank you so much. Better video than any other tutorial.

So wait... no riding test? Speed test?

I just ordered all of this. Only thing I couldn’t see from the videos I’ve watched is a acceleration run. The video that you showed top speed seemed like it took a long time to get there.

The bar ends are so when u wreck the bar doesn't stab into u and never use soap to put grips on. They won't dry and slip off

Hey what is the battery life for it?

Thanks for the tutorial. I followed everything you did and same parts but in high mode I’m getting 23 mph. Do you know a fix?

I have the same kit what tooth rear sprocket would you recommend cause the stock one just makes the rear spin out

Were those brand new wheels and tires? If so, where did you purchase? Mine are very rusty. Also do you have a link to the chain?

Great video, but curious says Tesla inspired build are they Tesla batteries? What makes it a Tesla build.

Fantastic tutorial, planning on doing this but I was curious if you used the same chain as the stock one ( length wise ), sorry if I missed you saying it. Please let me know asap, thanks!

Where does the single yellow wire go that comes with the throttle? Is it important?

My front and back wheel barely moves when I try to spin it after putting on the new brakes. Whats the problem?

Excuse my ignorance it they haven’t thought me this in school, why is it important to read the voltage and how do you read it ?

The batter connecter does not go into the controller any tips on how to fix it

Can you use the 1800 watt motor with the stock razor batteries

How did you get that throttle to stay onto the bar? Mine keeps sliding off

Is it normal for my chain to not move when moving it forward when off but when on it works going forward? And it moves when off only going backwards

Thank you so much for doing this!!!

what if the motor isn’t stock in high and i don’t get the 3 speed throttle how do i permanently keep it in high mode

What charger does the battery use

Will the 20 ah battery work in the build shown in the video?

Hey I bought everything from the description.. starting the build tomorrow one question.. should I unplug the battery from the controller while charging the battery?

Is getting the 20ah battery a good idea or should I just stick with the normal one?

My drive sprocket is on the other side. So my motor would need to be placed in the other side. That means it will go in reverse on throttle. How do I change that on the control box?

Can you make a video on the elock too because you skipped it

Hey I’m looking to do the same build this video really encouraged me to do it and helped me I was wondering what you use to charge it because the battery does not come with it

so i did this build super super helpful one last question? How long does it take for the battery to charge when it is fully empty?

This is the best video on this upgrade where is the parts location list I want to purchase everything used in this tutorial. Thanks

How did you splice the yellow throttle wire to the red wire going to the step down converter?

How do you change it to high mode I think mine is in medium bc i did everything you did and it only gkes 23

What are all of the tools you need to assemble it all together?

Do you think you would know a solution? I got the same battery and motor kit as you but I’m topping out at 26mph

What rear sprocket do you use and can you put a link to it

I just did this upgrade to my son’s but used the factory 11T gear. It’s way too much torque for a 90lb rider. Does the 13T sprocket slow down the hole shot noticeable enough that it doesn’t ride a wheelie half a football field?

I ordered a chain tensioner and the barrier that’s across from the two like thingys that spin keeps moving when I ride and won’t stay up. It hits the chain and I tried to adjust with the nut but it still moves. This is the 2nd one I have because last time I left it and it broken the barrier

Great video! Did you have to tap new threads to mount the new motor? I can't quite tell what you did from the video. I've head that the spacing is wider on newer motors. I've also heard that the 1000W or greater motors don't have recessed bolts.

isnt it bad to rap a battery in styrofoam, i want to do it but where i live it gets to 90 some days, just wondering if it is bad

Do we need to put fuses? And if so where?

Do I need a new controller if I have a 48v battery and motor

Hey man I'm gonna do this build but i do have a question, Is this build water proof because i want to make sure i don't ruin the bike when i clean it!! thanks man for the video this will help me so much the wiring couldn't do it without you.

When I ride my chain keeps coming off. Any tips or do you know how to fix it?

We have a throttle with a volt meter we aren't doing 3 speed so it's just throttle and volt meter. We have a Red, Green, and Black wire on the throttle all in one clip and then a yellow and blue wire each in heat clips. What is the coloring for the wires into the controller you used?

I did everything you said for the connections and checked all the connections and I get nothing. Nothing moves. I even hooked up the on off switch. Do you know a possible reason for this?

I have a question, can you clarify how to turn the bike on and off? i cant imagine charging it while its on

I am building this I put everything in the bike and when I throttle it’s not working, it shows the power on the volt meter so I know the controller is getting power, is there a chance that some metal got in the motor and that’s why it’s not working or is it something else

If I got the 48 V 20 AHH battery what do you think would be the range

Just finished my build but for some reason when I sit on it I hear a grinding metal sound, but only when I'm sitting on it, any thoughts?

would this work with the moto tec electric dirt bike 48v 1600w version yes or no

Hi I finished my mx500 build but the motor came in medium mode for me I don't have a 3 speed throttle is there a way I can change it for it to be always in high mode?

Hey, how do you put the controller into tho r frame

Also where do you recommend buying the bike from

Where and how did u mount ur controller ?

what size brake rotor did you use for this

Isn't the rear disc brake 140mm? When you upgrade them to 160mm does the brake set accommodate for that? Thanks!

Did the motor hall center have a red wire cut. Mine does, it’s looks like it’s on purpose but i don’t know. Thanks

On my controller the battery connector was just a wire without that metal circle, to connect the battery to that can I just shrink wrap them together?

For the modification to motor does it matter what drill or do u just drill the hole a little bit deeper

Will a 30ah battery work too and how much ride time will u get with the 20ah battery

Hey man, great video, it was really helpful! On your link for the battery it says its rated for 1200w and I was told I would need a 50amp bms in the battery to run the 1800w kit. Have you had any issues running your battery?

This build won’t apply or work for max 350 or 400?

For the weatherproof thing did you have anything on it or something covering it?

Had a question how would you turn on the bike and turn it off because it doesn’t have a key switch or anything

I got the same breaks as you but my discs won’t line up with the screw holes

The battery that you put isn’t coming up do you know name of any other ones that a good price

I bought the exact same throttle as you did twice because the first time the 2nd gear did not work and now it happened again with the new one. Did that happen with you?

Just finished my build. I have a key switch throttle and the voltage meter is always on, any fix for this? I also top out at 21MPH on the stock sprocket - could it possibly be in the lowest power mode as I don’t have a 3 speed? Thanks!

Thanks! One quick question how do you charge the battery.

is there a mph display to conect to the bike

Where did you get those jumper wires in the beginning of the video

@B Rich. I’m using the links you provided and when I go to eBay for the 48v lithium battery it makes you select for type of motor it will be used for, the only selection available is for the

Are the wires that go into the e lock the 2 large wires that come out of the on off switch?

Great video thanks! I have a question about your battery and motor… the battery you linked says max of 1200w output but you’re using it with an 1800w motor. Does that just make the motor run slower…?

Hey Brother, great video, would you have the links for the Velcro straps?

Started this build today and followed your tutorial, after connecting everything the throttle wouldn’t light up or work at all. Any suggestions? Thanks!

do you know how many miles you can get on a charge?

Does the voltmeter turn off when you turn off the controller?

I added everything in my cart from the description not including head light stuff and plastics and it’s over $500 the video says $420?

Thanks for making my decision easier to make. I wasn't trying to spend alot this worked out perfect for me. Just bought same bike, same vevor kit and battery with charger. Am I missing anything else that is needed? I read the description and noticed there's alot listed but I'm basically looking to start out bare minimum upgrade later. Is heat sink highly recommended? Thanks.

Do u need a junction box and does it come in the moter and controller throttle kit?

I just got the vevor motor and controller kit, and the stock sprocket that came on it won’t fit with the stock razor chain, is there a specific size chain that anyone can recommend?

is thier a optional key fob?

could i use a 12V on off switch wired to the e lock port

awesome video, thanks for doing this. sub'd!

Would the 20ah be the same installation as the 14ah?

I’ve been enjoying mine for a while until today , have you ever experience throttle problems ? At first it was getting stuck , but now my throttle is not responding at all 😕 Do you have any tips ?

Can you give me the dimensions of the frame and swingarm ? On the mx

Did you purchase the battery with a charger or did you wire the battery into the existing razor charge port?

I decided to keep the throttle from the kit how do i wire it to always be in high speed

does that lil jumper wire come with the kit?

for the 3 speed do you just rip the original connectors off or do you use a tool, also where does the yellow wire go

What was the step down controller for?

Got everything and the rotors don’t fit. I have the exact same bike. 😔

how do i get the original black connectors off the 3 speed, do i cut them? i’m confused

Were can i buy all the stuff from

Just one question, does the yellow wire from the 3 speed go to both the black and orange wire, indicator light? I am not using the voltage reducer.

What brake rosters did you use? I got the hydraulic brakes on Amazon that you suggested but the rosters didn’t fit.
