Best video of razor ungrades out there! Thank you, will be using this video religiously this winter

Thanks for your video! Very interesting, informative and helpful video!

Great video love the 80s carpeted garage

Best video on YT can’t wait to do my my swap now

15:36 Great old skool word. Don't hear it enough anymore.

How did you connect the on and off switch? It has two red wires. And the brake connector your reusing has black and red.

Lithium batteries will give u a little more power but good job and nice tip on the chain that most people overlook!

How did you wire the charger, I didn’t see that. If I missed it can someone say what time he did. Amazing video Thanks

How do you charge all the batteries at the same time ? If you have any idea that will be great I been trying to figure that out

I am going to do this, do you have a wiring diagram? And for the torque, try a lower number of teeth front sprocket.

Merci pour la vidéo, jai exactement le même setup de moteur sur une moto style mini baja, ca roule sur le stand la roue en l'air mais des que je le met au sol avec du poids le moteur na aucune puissance et donne un son de de moteur qui aime pas ca du-tout et de plus les fils du moteur deviens chaud en quelque sec mais pas sur le bench test , sur le bench test ou la moto sur le stand tout roule a merveille. Donc pansant que cest le moteur ou le contrôleur qui es défectueux , jai acheter le même model en 48v 2000w et meme chose, vous avez eu se problème ?

hey Would you still have the stock motor?? I'm looking for 1 to put in my nephews mini bike running of A 10s lipo pack

I have a question do you have to solder is their any other thing you could do I’m confuse

Great video. I'm in the process now of rebuilding an old razors scooter moped that was my daughters. I installed a 48 V, 1800 W motor as well. I'm in the wiring process so I'm close to being done and I am doing it just about exactly as you're doing it of course I'm following along based on your instructions. But I have a question, and that is regarding some of the wire gauge. I clipped some of the stock connectors off of the old scooters I had and I see that there is a mix between 16 and 14 gauge wire. everything I read based on the amperage with this motor set up says to make sure you use 12 gauge or 10 gauge for power. I may have missed it in your video but did you switch out any of the stock wire from the connectors to a bigger wire or did you just use the stock wire which was probably 14 gauge? and if you used the stock wire have you run into any issues with it? Thanks

Great video man! Very clear explanation I do have a quick question what size back sprocket you using 55 T? And the front is a 11 T? Thank you

Hey, i was wondering what kind of batteries you used?

What charger did you use after you did the 48v conversion

Well done

Hello i have bought a 1800w 48v motor recently and am struggling with finding a good battery i dont have that big of a budget could you please help me find a good motor?

Can you give the link the charger and did the charger work well?

What Ah battery you using? Converting a gokart with this motor and looking at 100ah batteries on aliexpress

What kit did u use and where did u get it from?

This is an exceptional video. Thank you very much for doing this. I have three kids that I have been modifying MX500's and an MX350 for, and Dad's everywhere are lucky to have this video available. Quick question. My controller has a keylock with a red and orange wire, and I would like to hook it up to the stock MX500 on/off switch, which has two red wires coming out of it. How do I do this? Thank you!

Your 3 way switch is a on off on switch or a on on on switch?

Why not link to the stuff you bought in the description?

what batterys and sprocket are you using to for the 1800w motor. i recently bought a 1800w motor but i have a budget and i cant find any batterys that would work for under $400 please help

I really want to do this how hard do u think it was?

Hello I am too soon going to be in the process of building one around probably December

What batterys did you use ?

What bolts did you use to connect the motor to the controller? You just covered it with electrical tape afterwards?

Is that the electricscooterparts kit?

I wonder what would happen if you put that motor on a bike with gears

I installed the same motor kit and controller with the same throttle assembly with 4 new batteries. Ran a great test run but even after charging overnight it won't run with a load on it. Any suggestions

This is the same kit I bought it’s for my mx400

Were you saying that you didnt have enough torque with this build ? I installed what looks like the same kit with the only difference being is that i bought a throttle that had the voltage meter built in it. Mine has incredible torque , and the throttle is so touchy on the initial takeoff it will knock you over backwards if im not really careful . Almost very flippin dangerous . Im thinking about changing the gearing by a tooth or two to take a little off the bottom end

Can you please tell me what is the battery and Controller rating ,also link to buy the Controller

Steel sparks because it’s ferrous not because it’s a hard metal btw

How did you get the original sprocket from the new motor off? I took off the nut and washer but the sprocket won't budge.

How Many ah is The batteries and how Many Amps does The controller use

5/8 or .625 ! Nice video though. Addresses most of the problems I have seen.

im trying ti use the same motor and am getting no torque my bike is a puch magnum frame with 14 front gear and 45 rear ...

How long do the batteries last? Do you know What amp hour battery would be best to get close to two hours of riding time?

“no stop sign”…..i see no problem here..lol

What kind of run time /mileage have you gotten with this setup ?

How can you change the pinion of the motor? I have the same one but i want to make a different pinion on it...

how do you charge it?

cool. Do you know what's the weight of that 1800w motor ?? I am thinking of buying it on ebay.

i run 60 volt li ion and everything else stock and i hit 29 mph pretty easily

im thinking of putting one of these puppys in my trike. i already have 52Ah battery.

Is that a red model of the mx650

All you needed to do is buy a powerful controller. 2000w 48v to 60v 35A for £40 and it would be faster. Less work and much cheaper.

Hey bro you can buy a 48v 20ah battery off of eBay for like $210.00 and it fits on the bottom shelf perfect ,just make sure it has a 30amp bms.

solder and heat srink it

45 Km/h = top speed
