This is the best tutorial video i ever saw. i watched so many and they skipped the 2 steps you showed. THANK YOU.
Glad I could help others out. Have fun riding your bike
Can you use the mx350 ? Mine goes 23mph. I want to upgrade my 3rd one.
I have to say I am very impressed. Some other guy made a guide to adding a 50cc without welding anything and it was a clean build - but prob spent way more than you guys. Plus this just shows skill. Very cool.
In burbs electric is must as gas will annoy neighbors
Great video. I just received all the parts and giving them to my son for Christmas. He has been wanting this setup for a couple years but I was hesitant about doing it. Thank you for a very easy to follow video. We have 2 bikes and eventually we will do both.
Glad I could help
I like using brass brads (the ones for binding papers) as bridges for testing, and sometimes long for long term. They slide in perfectly and stay tight
Great idea
subscribed for giving us something short, sweet, into detail and a cheap alternative.
Glad I can help other razor owners out
Wow, i’ve been looking for a tutorial for ever to help me because i’m new to this stuff, thank you so much!
Glad it was helpful
Thanks Rich! you are single handedly helping me make decisions to get a bike
And on the road! For Best Bang for my buck!
Glad I could help other people out
Thank you for making such a detailed step-by-step tutorial.
Glad it can help othets
@@BRichSolution where do you connect the voltage meter yellow wire from the throttle?
Thanks for the detailed video, DUE TO THIS QUALITY VIDEO..I HAVE SUBSCRIBED!!
Thank you
Best budget razor vid ive ever seen
Thanks man
Thank you so much. Better video than any other tutorial.
Glad it helped and reason why I made the video
Awesome video. Subscribed! Thanks for all the links.
Glad it helped you out
used this guide to build mine and it works great, thx man
Glad I could help others out as that was my intention
How long did this take to build?
@@jingostanklong1265 about 6 hours to strip it and install the new motor, controller, and battery (along with the throttle), and probably spent another like 12 hours installing brakes, plastics, rotor disks, keyswitch, etc
Thank you so much for doing this!!!
I’m glad I can help other owners out
I have a 3kw motor, same vevor kit. I'm using overboard batteries and xt60 adapters to splice everything together. I'll eventually buy a solder kit and actually wire the batteries correctly. This all is going on a mx650. I'll be drilling holes in the frame because of those screws. I'm kinda new to all this, so I hope I don't mess anything up.
I would not drill holes in the frame especially with 72V / 3000W; recess the 2 screws in the motor see video 8:00 mark
Sounds familiar..... is this who I think it is lmao??
As B rich mentioned, unscrew the bolt, recess the screw head on the plate and repeat for the other two just in case you need to play with fitment. The screws will then sit flush and you can cut, grind or leave (if you have clearance) the extended screw ends off the opposite end.
Great vid, I was planning to try this out and follow your video but was wondering if you could just use a standard drill bit to recess the screw holes or do you need a special one.
Yes, standard drill bit it what i used. The aluminum drills out very easy.
What size drill bit did you use and what happens when you recess it , is it just making the hole deeper ?
Love your videos. I already over-volted my son's MX650 to a 48V 20Ah lithium linked in another of your videos. Also installed lights thanks to your help. Considering getting him this motor and controller for Christmas. Any issues running the 1800W motor with the ebay battery rated for 1200W? The 35A 20Ah I got is rated for 1500W, but still under the wattage of this motor. Thanks again for sharing all this great content!
No issues running 48v with 1800w motor kit. I believe the battery bms states 30amp but its more like 40A as i see no degrade in performance until voltage drops below 45V so that tells me 1800w / 45V = 40Amps
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.
New rotors bolts same thread as stock threads. No drill or tap required…bolts right on. As for the motor 2 screws need to be recessed as show in my video. If you buy more expensive kits the bolts will be recessed
awesome video, thanks for doing this. sub'd!
Thanks for feedback and glad I could help others out
love the video, where did you get the jumper cables?
Used a scrap piece of wire 1” long
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?
No issues with performance with the 14Ah or 20Ah battery
That's good to hear 😁 Thanks for the reply bud!
So glad I found this! Gonna be attempting this on the weekend. Is it best to wire a fuse in the set up or is it not necessary. Thanks for the amazing video!
Not needed as the battery has a BMS bit you can if you want extra layer of protection
I’m about to do this once I save up the money. Great tutorial. How long does the battery last?
12 miles in high longer mixed riding
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
The soapy water dried and grips tight
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!
Yes, correct use stock chain
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
There is an option to buy battery with or without charger
If you didn’t order with charger this one work with the battery charge port amzn.to/476zig7
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.
I’d get the hydraulic brakes and calipers for $60-70 as the stock brakes are insufficient for speed above 25 mph.
Hey Brother, great video, would you have the links for the Velcro straps?
I believe they were 18” long straps here is link to variety pack for $8.99
amzn.to/3ZCOpcH
I did the $20 +5 kit I might do this next for more speed.
Good idea to upgrade in steps
Thanks again for the video! I didn’t use the 3 speed throttle and it’s a bit jumpy at initial start, can I reduce the snappy start with a better throttle or different sprocket? Thanks!
Go to 12 or 13 tooth sprocket will make it less jumpy
@@BRichSolution is it a standard 13t sprocket- 4mm thickness (25h chain) 8.5 by 10mm sprocket?
Hi I am not sure if you are checking comments, but thank you so much for the video. I have managed to get to the point where all I need to do is wire the on and off switch. I can’t quite figure out what I need to do there. Do you think you could give me some advice?
glad I could help.... I forgot o film the the wiring on/off switch but you can see it wired at 28:57 in this video
Can you do a video showing how to plug in the stock on an off switch to the E Lockport
You can see wiring in this video at 29:00 and my other video has diagrams czcams.com/video/thfQyCmczlk/video.html at 5:40
And also how did you connect the on/off switch to the side panels you didn’t show that in the video or do you just unplug the battery
See video at 28:57 for connecting on/off switch
do you mind explaining how the display shows the voltage? I get that you splice it but where does that connector hook up to?
Voltage display you can splice to any connector on the controller outputting 48V like the indicator harness or splice into charge red wire on charge port
Does this apply to the mx350?
Nice vid bro
Mx350 and mx400 frame is smaller and motor mounts would need to modified
I wrapped the whole battery up in that foam and wrapped it up good with duct tape. So basically it is covered all the way around with 1/2 of that foam that came in the box and completely wrapped and sealed in duct tape. What do you think? Could it possibly get to hot and maybe catch fire or blow up? Thanks.
I left some of the ends open to vent and breath a little
Bro this is a good diy video thank you. Any updates how is it holding up?
I have two bikes with this setup. Both still running strong no issues
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…?
No, the 1200w option battery has minimum of 30 amp output BMS so it can supply the 1800w motor. I used this battery it my 1800w builds
I don’t understand? I’ve been looking for a battery to power my 48v 2000w motor but all 48v batteries I find are rated at 1800w max… what should I be looking for?
Did you purchase the battery with a charger or did you wire the battery into the existing razor charge port?
Battery with charger and let the factory charge port hang out the back by the motor. It shows it in the video
thank you so much
Glad I can help
@@BRichSolution also do you think it would work on a mx350 or is it just too small
@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
1200w battery is sufficient 48v with 30A discharge
Thanks for the quick response! If I just start with the upgraded battery first, do you recommend anything else since I have the bike apart? Like the heat shrink or anything?
I finally got everything in to upgrade to the 48v lithium batteries you had linked using the stock controller and motor. Which video of yours is the best to use showing the steps to install this please? Thanks
I have a question? Is it possible to run the SX500 wheels on the MX500 or MX650 . I’m looking to see if I could run a set of the smaller ones instead of the MX stock ones? Please let me know if possible and if not what alternatives are there? Please and thank you
Yes you can put sx500 front wheel on mx500 or mx650 and vise versa
For the modification to motor does it matter what drill or do u just drill the hole a little bit deeper
Just drill the hole a little
deeper so the head of the bolts are below flush so motor can mount in frame
How do you wire the on/off switch can you show how to do that? Thanks for the detailed video it really helped
With the on / off switch to the elock harness on new controller, see video at 29:04
@@BRichSolutionalso where do I get one of those jumper wires what do I search up
@@BRichSolutionalso where can I get that jumper cable in details because I do not know much about wiring
My son has mx125 with upgraded makita 18v power tool battery. It goes a little faster and longer playtime for him. Also looking to get a used mx650 wanted to upgrade just the battery into lithium for longer riding time as well but also keep same motor and controller. My question is 48v 20ah a good idea for it or bad? Thanks in advance if you ever or not reply. Awesome builds!
20ah battery option is a great idea the bike will run for a long time
How do you do the Elock part? I know you mentioned it at the end of the video, but you never showed us how to do it.
collect the 2 wires coming out of on/off switch on the razor to 2 wires on the elock port. If the switch turns on when it off then reverse the wires.
Does the brake rotor you listed in the description come with 2 or 1?
1
Do you know is the original charging brick/cable is compatible with this battery if you use the existing charge port and controller connection? You mention it around 14:11 but the input and output ratings on the charge cable that comes with the battery are different than the stock charger and I don't know enough about the electronics side to know if that would still work. Thanks.
no the old charger is 36v, you need a new charger that is 48v
do you need to wire the e lock to the stock on off switch or can you just bypass the old switch and only have the e lock switch?
You can bypass the stock switch
Do you use the stock on/off button for this build, and if I didn’t want to do the headlights/with the switch would I still need the step down transformer?
See video at 28:57 for on/off switch wirings. Step down transformer not need if you forego headlight
Hey just built mine and I love it! I’m running an 11 tooth sprocket with on flat ground goes around 20-25 miles per hour with a 110 pound person on it. Do you think I’m stuck in mode 2 or is it the sprocket?
Yes stuck in default mode 2, wire the 3 speed wire harness as shown video with jumper wire to mode 3 or high. You you be at 30 mph with 11T sprocket
@@BRichSolution does this apply to the single speed throttle?
How long did this build take?
@@jingostanklong1265 in total 1 week if you count how long it took for everything to arrive, i wired it all up in less than 3 hours when it arrived
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
It did not
Can you use the stock charger without using the lights with the step down transformer
No
I have had a problem with the free wheel breaking due to the high power of the bike I was wondering if you have a solution to help the free wheel to not break or you just buy a new one?
I wish I had a solution. Try new free wheel and if the tire is worn by full assembly as it might be cheaper. You could try welding the free wheel hub
Thanks! One quick question how do you charge the battery.
Use the charger that came with the battery run the pig tail of the charger port out the back of battery box and charge it there.
For the weatherproof thing did you have anything on it or something covering it?
I made sure the connections and controller are packaged inside the battery box
I was about to buy the whole kit but I had a question, what gauge is the jumper wires?
I just use some scrap 16 or 18 awg to test the system
If you are still responding to comments on this build... if I use the stock motor sprocket and use the stock chain it will be snappy (good for wheelies, 32mph according to you) will it still be a comfortable ride when not doing wheelies? I just don't want it to be so snappy it throw's someone off the back... thank you for the help and this great tutorial.
It will not throw the person off you’ll be good
Can you make a video of how you connected the batter to on and off cause I don’t know what switch to use
See video at 28:57
I simply wire the two wire going to the on/off switch to the two wires on the elock harness
@@BRichSolution is it the bigger or smaller switch
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?
Blue and yellow wires go to indicator harness on the controller. 3 throttle wires go to the throttle harness on controller
This I a great tutorial but I was wondering about the heatsink. Did I come with the kit? Do you need one or will it overheat? Where can I get one?
You dont need the heat sink u less heavy rider. You buy it separately for $30 if you need it
Oh ok thanks
would it be fine to add the upgrades to a mototec? just the performance upgrades
i have the 48v pro version
Yes you can add this to mototec 48v but you may want to upgrade the batteries if mototec don’t last long
Just asking is the heat on the battery and cables needed or optional? And also the yellow box is not available on Amazon. Any substitutions for it?
Heat gun melts the solder and waterproof seals the connection you can also use lever connectors if you don’t want use solder/seal connectors. Here is updated link to junction box amzn.to/4c4rvRI
@@BRichSolutionthanks man! Can this thing also do wheelies?!? 🤪
Question!! Do i need the step down unit if im not using a 3 speed throttle? Also whats the benefit of getting the 3 speed throttle vs the throttle that comes with the engine
No you don’t need the step down transformer for the throttle, its only need to run the headlights and taillights as they are 12 volts. You can use the single speed throttle that comes with the motor kit but be sure the motor is in high gear all the time by using jumper wire on the 3 speed wire harness on the controller: see video at 5:16. The benefit of having a 3 speed is better control in low gear off road. Also if kids rides ride the bike you can lower the gear
@@BRichSolution hey thank you so much for the reply I appreciate the help!
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.
Try yellow to orange, yellow to black os low. See video at 6:06
@@BRichSolution Ok thank you very much. It’s a Christmas gift for him so we will be attempting it after that. Thanks again.
Do you think you can post where you got all the stuff because I’m trying to put together kit and it’s going well over $550
all the products used in video are in description below the video.
My bike has worked great but recently there is like a short in my bike and I don’t know where it would be do you know any possible places where the shirt would be?
What connectors did you use?
Take battery cover off twist the throttle in dark garage and you will see blue spark
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.
I went with 13T to lower the torque so I wouldn’t wheelie. If you keep 11T you will gain speed quick but top speed will be reduced to 32 mph
@@BRichSolution yeah I ended up holding off on the 13t. I also have a razor pocket mod (moped) I got them both free. And I’m gonna build it next if this one goes good
Sorry I forgot to ask. Can you keep the jumper wire permanently for the elock
You can or just cut the harness off and butt connect the wires together
does this build work for a sx 500. also , can you list the 20ah version of the battery in the description as well
Yes it will work. And he did leave the link below . Click it and you can choose other options for the battery’s.
Yes it works. More room in battery box with sx500. First build was sx500 see video. czcams.com/video/wibJJIOLc58/video.html
Are the wires that go into the e lock the 2 large wires that come out of the on off switch?
Yes
In this video you used the 14ah version of the 48v battery and I am going to do the 20ah version for more ride time, is all of the wiring the same between those two battery’s? Thank you.
Yes same wiring for 20Ah battery. Enjoy and good luck
This is the best tutorial! Unfortunately, I haven’t been able
To get setup to work after trying the 3 speed throttle. It worked with the throttle that came with just but won’t with three speed. I tried to plug back in regular throttle and now it won’t work either. Any help would be greatly appreciated. Ordered everything from the video link.
Does the elock port have a switch or jumper wire? You can used just the single speed throttle and wire the 3 speed in high
@@BRichSolution the elock has a switch. I tried switching back to the single speed throttle but it’s not working anymore. I did originally when I tested before trying the three speed. After I couldn’t get the three speed to work, I tried going back to the single now nothing will work. Is it possible I shorted something out our ruined the controller/motor? Thanks btw! Just a dad trying to spend quality time with my boys. I have limited electric skills but wanting to learn and teach them along the way
I got it to work! Originally I was usi the quick connects before I committed to crimping. I decided to start over and do overthibg the video said. After putting the connectors on it worked! Thanks again man
Where did you get those jumper wires in the beginning of the video
just use a spare wire about 1 inch long that I found in my garage
How did you mount the controller? Also, if you're not using the 3 speed throttle, do you just leave the jumper cable in the 3 speed throttle?
Screwed controller to frame
Cut 3 speed wires and connect to make high speed
@@BRichSolution thank you, got the controller mounted to the frame. Using a single speed throttle and left the jumper on high speed. I left on the stock brakes, what do you do with the two brake connectors?
What size do you get for grips? 7/8 and 1in for throttle side?
7/8” scott grips are squishy enough to slide on. See link the scott grips in the description under the video
Isn't the rear disc brake 140mm? When you upgrade them to 160mm does the brake set accommodate for that? Thanks!
When you upgrade to hydraulic brakes the stock 3mm thick rotors will not fit and you need 2mm thick rotors that are 160mm diameter. See parts list www.amazon.com/shop/brich/list/2A0OX01IQELT4?ref_=cm_sw_r_apin_aipsflist_aipsfbrich_HACDTVEAKMBVKX6M3P5T
How did you splice the yellow throttle wire to the red wire going to the step down converter?
Used a butt connector: one side was + from indicator harness from controller the other end of butt connector put both wires (yellow from throttle and step down transformer wire) in connector
@@BRichSolution thanks
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.
Yes weatherproof as I have rode in the rain no issues
@@BRichSolution Thank you!
Do you think you could possibly fit bbr forks on a mx650?
Not sure
I saw that he used wires to get everything to get going but i couldn't jump start the bike every time i wanted to ride it and wanted to find an on/off switch that would be compatible with the bike. Are there any recommendations?
Wire the elock switch to factory on/off switch
This is the best video on this upgrade where is the parts location list I want to purchase everything used in this tutorial. Thanks
Glad it helped
Im also building a 48v SX500 bike, but need a different on/off switch. Do you know one with a connecter that fits the 48v ESC?
The stock on/off switch on the razor you can wire to the elock port in the 1800w controller
@@BRichSolution Thank you very much!
When I wireup the t connector to the controller is it supposed to spark when I plug it in to the battery
Yes spark is normal
Where do u get the jumper wires to make the 3 speed work
The jumper wire was spare piece of wire i had laying around. You can always cut off the connector and wire together the 2 wires needed for high gear
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?
Yes
What brake rosters did you use? I got the hydraulic brakes on Amazon that you suggested but the rosters didn’t fit.
Yes you need 2mm thick rotors with 48mm bolt pattern. amzn.to/3LmX7Wi
@@BRichSolution Alright thanks for the help and the video.
i’m a little confused on the 3 speed wiring, am i going to need any specific tools to make that happen? i’m new to this stuff and just want it to work overall in the end
No special tools: you can permanently wire it high by connecting 2 wires and use the single speed throttle or use a 3 speed throttle and connect the wires to the 3 speed harness on the controller using butt connectors or solder and seal connectors
@@BRichSolution Thanks so much
If you use the 20ah version of the battery how far do you think it will go before it’s dead?
20-25 miles or more with full throttle. Could go further (30 miles) if not in high gear or full throttle all the time
Do you know if crf50 plastics will fit on a sx500?
Did you use the same rotor for front and back?
yes same rotor front and rear. amzn.to/3LmX7Wi
i love this vid so much i think i might give it a shot what do you think
Sounds good and thanks for the feedback
Question. I bought same kit but when I hook everything up throttle is coming on but motor is not running? Any ideas. I did the red jumper.
See video at 4:28 and connect elock port
will i be able to get a key throttle to fit with the controller, and it still be able to run?
yes, but you'll need the wire the key throttle wires to the "E-lock" wire harness on controller to turn bike on/off
I think my motor is stuck in medium. How do I wire it so it’s in High (I do not have a 3 speed throttle)
See video at 5:16 for wiring 3 speed in high
What Velcro straps did you use?
amzn.to/3Tq3pHE
also if i had a key ignition throttle would i have to do the on/off swich
No ignition key can replace on/off switch
I I have having a great time with my upgraded bike, however the motor started to over heat after a little while. What heat sink did you use?
motor heat sink: ebay.us/SDi2Xt
Thank you
how do i get the original black connectors off the 3 speed, do i cut them? i’m confused
Pull wires out of black connectors or cut the wires
can i buy some of the items and install them and then whenever i save up enough money and buy the other items? Like can i just buy the brakes now or wait till i can buy everything.
Yes, start with the battery and connect to stock controller & motor. Ride that for a few months and then upgrade motor see this video czcams.com/video/kRvYAI1hdc4/video.html
I can’t figure out how to wire the on and off switch because I’m not using the step down transformer and also what wires did you use? and you think you can make it so you don’t have to use the on and off switch and immediately turn it off by the battery
Wire the factory on/off switch to the elock harness on controller
@@BRichSolution ok thank you
