- Today we upgrade and modify and upgrade my Razor SX500 e-bike mini motorcycle with a 72v 3000w system! Thanks to surronster for inspiring this video with his own MX650 upgrade - this is an upgrade option for Razor owners looking to build a 72 volt, high voltage system on their own e-bike without breaking the bank :)
PARTS TO UPGRADE YOUR OWN RAZOR SX500 RSF650 MX650 or MX500: linked in comments!
This is my first electric bike build / project, so I hope you enjoyed the video! - Auta a dopravní prostředky
For everyone asking, BATTERY IS BACK IN STOCK!!
**Parts list:**
72v 3000w Motor + controller kit: amzn.to/3pmls4m
72v 20 amp hour battery: amzn.to/3qsflvM
E-bike twist throttle: amzn.to/3QQ6bEQ
E-bike voltage meter + key-on: amzn.to/3dwrlcC
Hey I was trying the link for the 72v 20 amp hour battery
But it didn’t work
What do I so
Do
@@kennethrascon6414 UPDATE: the battery is no longer for sale :-/ looking for an alternative, sorry for the confusion everyone
I have been going through your sx500 vids and it inspired me to make my own so I cant wait to do that with this parts
I'm just now getting into the e bikes coming from 2 stroke racing bikes, and I really wanted to start with a Surron. However, when I saw someone doing this I thought it was super cool and this will be my first e bike to modify and see how I like it before I dish out thousands more for a bigger one. Great video man
that’s a great way to do it - coming from cars that’s exactly what I did. Fair warning, you’ll probably end up getting a surron. I did. Both amazing bikes in their own ways.
Better to just get a surron. After all the upgrades the cost becomes absurd. 72v high output battery 900+, motor $600+, controller. $400+, wheels/brakes/suspension, etc, another $1000. That's already $3k and it's without the donor bike. 3k will already get you a used surron.
@@DescartesRenegadeit’s faster than a sur ron
@@joeyb7084 faster is just one aspect. It's no where near as comfortable.
this is a big inspiration to me to keep going cuz im building my own mx650, and i thought itd be funny to slam it to the ground, and now im all in with the build
Hell yeah!! That's such a good idea keep me posted.
Currently binging all the ebike stuff 👌🏻love from london
thanks g 🙏 I appreciate that
big help on mine for fixing seating was move front bars foward a few inches.. felt way more stable and moved that COG
Good call - simple and effective. I’ll give it a shot.
always wanted to get a mini e moto project going. love the ronster, but only own e scooters myself. need a bike in my life! sick ride bro.
do it!! The fun levels are unmatched
I recommend getting bigger bars it makes the ride so much better
The kelly controllers are much smaller and quite good. Makes it easier to build. The motors are rated 3000, but they have no control over how much power you push through it.
100% true, in my latest video I swapped for a KVD with great results
Good video (except the first half, camera was making me motion sick) but I listened thru as I’d look away for moments at a time. Once you get to actual testing the footage was good. Definitely upgrade those brakes cause I was worried for you on those runs lol
Thank you so much 😊
Same I got inspired by him too I love him
Can’t wait to run into you around the town! Let’s Goooooo
yessss
Pat Outdoors is doing a Razor Mods. Freaking Cool stuff.
I’ve seen some of his videos, great 48v content!
Legendary but terrifying 👐 just the way we like it
You better let me ride this when I come to town in 3 weeks
@@willywonkastwin hahaha alright you got it.
I love the idea of this mod but I am a taller guy and I get the feeling that you may be close to my 6'1" height as well. I would want to explore elongating the frame by a couple inches and moving the pegs forward a bit if possible. This would not only make the fit better but would also help with the front end wanting to lift. I might also want to try another controller where you can modify the action of the throttle... maybe.
Please make a in depth video on how to make and rig this thing up 🙏🙏🙏
You got a voice of a professional. I feel you could be CZcams famous one day lol. Camera was shaken too much while you hold it but other then that, thumps up on the vid. I’ve always wondered if the cheap way is worth it. I got the electro & co kit not 1000 tho
Thanks so much man! And yes I’ve definitely heard that feedback before, noted :)
Imho I think the cheap way is worth it for everything except the controller. And the full e&c kit is awesome, i’m jealous you got it.
Dude I freaking love your reaction. It's hilarious. Just got yourself a new subscriber and I was wondering if you've gotten use to the touchy throttle?
hahah thank you, I was really scared. I did get used to it, it's really not that bad on Mode 1 after a few days and a total blast to ride. I did end up upgrading the controller to something smoother + more powerful, so you'll see that video pop up some time next week :)
@@logan-taylor hell yeah man!!! I can't wait for the video!!! I seen the e&c kit but that $1600 price tag was a turn off for me. With the links you provided I'm roughly saving $400 - $600
@@brucewayne6858 WONDERFUL i’m so glad you saved some money, that was the big goal.
The reaction was so annoying and tedious
@@XbnsVvV unreal username. you win this round
I weigh 160 and have a 72v 11kw razor and I can confirm they are absolutely fun death traps, always wear a helmet (it's not cool to have your brains on the street) and upgrade those brakes to a big caliper and rotor cause stopping is more important than going fast lol
absolutely a death trap. The 11kw kit looks unreal. And fully agreed on brakes, this bike is waaaay different now haha
def looking into a 13t sprocket for stock chain and then 15t for shortened chain.. gain top end and be less harsh on take off.. i just did a sx500 build myself over the last two weekends and picked up a mx500 yesterday for the wife lol
that’s exactly my thought - I was thinking 13t so i can still have good torque for wheelies and stuff. Congrats on build #2, i’ll catch up with you soon!
@@logan-taylor yeah man no doubt. I also come from modding cars and drifting and stuff aswell. Cool to see someone making the same moves! I'm only 48v on my sx and managed to get 35mph out of it I'm more then sure you'll hit 42 at minimum
@@TURBOMOOSE that’s sick!!! it’s an easy transition, just fun motorized reckless stuff haha. I’ll order a sprocket from electro and co and see how i like it, thanks man.
yo i love sur ronster
Hey man love the build and im looking to do somthing similar, i was wondering if you ever found a different 72 volt battey and e bike voltage meter as the ones you listed arnt available anymore. Love the videos man!
thanks so much! And thank you for letting me know, the vendors keep switching up on us:
Key/volt meter: amzn.to/3UgJo7b
Battery - it seems like they’re no longer selling the 20ah version but i’m not 100% sure that the 30ah version will fit!! Make sure to measure your battery tray first if you decide to go this route, as I can’t guarantee fit: amzn.to/3UDqR4u
@@logan-taylor Will do! Thanks so much man
Could a different battery provide the same amount of speed? Wondering because 700 dollars is a ton to me.
Can you do a parts list explaining everything
Hi Logan I am doing a very similar build and was wondering which wire does what for the throttle? Thanks
Hey how did you learn to make this build? Nice vid btw. Keep it up you will become a huge hit in the future.
thanks so much!! And i just kind of figured it out as I went along with wiring diagrams and stuff :) Other than wiring it’s basically just a couple of bolts!
Does that ECS in the motor combo run the 72 volts or do you need a separate 72 volt ESC?
AWESOME
do you need the E-bike voltage meter + key-on
Hey man just curious how many mph does it go to?
is there an alternative battery?
Can you do more videos on razor bikes ? Lol 😂
Can you please make a video on how you wire everything please I just got all the parts but have no clue on how to wire it. I need help please your the best
oh no!! I don’t have the wiring diagram for this controller anymore but it should come with your kit - shoot me a DM on IG @loganandrewtaylor i’ll do my best to help!
How has the parts held up to today . Any problems you had?
What’s the black connector that you heat up for the battery can you link it
i weight 95 and im 13 and when he said at 160 your done i was like shitt im gon be on on my back everytime
hahaha you’d flyyyy dude
@@logan-taylor yh and love your vids btw really affordable for a lot of power
@@williamcarignan5326 thanks bro!
Hey, now that its been a while since you made this is there anything to say about how long the batteries last? Im thinking this would be better than a lower power gas bike but if I have to replace the most expensive part every few years that might change things.
How long does it last off 1 full charge?
cool project!! what that bike weight?
i’ve never weighed it but i would guess maybe 100lbs? About the same as a Surron.
Hey Logan! Have you had any issues with the Btr LiFePO4 battery? Mine won’t take charge past 72V…
hmm, i haven’t had any issues. Is your battery 72v or 60v? If they sent you a 60v, that might be max voltage?
yesss
Does it still work?
I have the same kit as yours, but my throttle wires are different. I have red, black, white for throttle and gray, yellow, blue for 3 speed. Black and orange for reverse. The controller wires are all correct. Your throttle wires are different than mine,do we have different throttles?
Sounds like it - I ordered my throttle separately! Actually just got a new one from Electro & Co, the one in this video isn’t the greatest.
Looking into getting this bike and I am pretty tall. For scale how tall are you so I know how big it is.
Hey just wondering how much did you say the bike was it self? Because I’m thinking of doing this bike on the rsf 650 but I don’t know if it will be more expensive
i think i paid like 2 or 3 hundred for the bike off of FB marketplace! RSF’s are definitely more expensive to buy but totally a cool frame
Hey bro I was just wondering is it hard to install all the things on there? I really wanted a bike for myself, but I’m too scared that I won’t be able to do it myself.
physically installing everything is pretty simple - it’s just some allen bolts basically. The wiring is pretty tricky and frustrating, but if you can find a plug-and-play kit it should be super easy. You got this!
what’s battery did you use?
whene i cliked the link for the moter and controller it says its a 2000 w 48 volt
Did you try reverse?
Is there a tutorial that you can make to go into detail on how to build thia
the biggest difference between the E&C kit and these big chineese controllers is that low end take off and smoothness, ive been using 80A big china controller for a year now and i just recently got the full E&C kit and it dosent have that feeling of its going to kill you everytime on intial take off, you dont even have to try to take off smoothly lol
It's good to hear your first hand experience -- I've been thinking more about going with the E&C tuned kelly controller for higher amperage + smoother takeoff. Was it a worthwhile upgrade?
@@logan-taylor personally I would say yes it was definitely worth it even though I’m already used to the way these China controllers behave haha it’s just nice having the extra torque and predictability!
@@highvoltfab alright you’ve convinced me, I’ll upgrade. Thanks for the info!
That Chinese controller last year year?
not sure if I 100% understand the question, but i’ve only been running the controller for a few weeks so not sure if it’ll last a year. I would assume it would though, and even if it didn’t it would be cheap to replace :)
I have a 48V kit on an MX500 and it does around 32 MPH…. Would you know if there’s some type of regulator that I can add on to reduce the power when my young son wants to ride it… my throttle has a 3 position switch which I was hoping would enable me to control the power output but it feels like all 3 positions are the same
i’ve always had trouble with the three modes, you’re not alone. If you could put some sort of resistor on a switch, you could hypothetically limit the voltage that the throttle sends to the controller when that switch is on? So full throttle would be like 2v instead of 5v, for example. That’s like a monkey brain idea but it would definitely reduce “twitchiness” in the throttle and make it safer for a youngster -
What 48v kit do you have?
What size battery y’all recommend
My 10yr old son has a MX650 all stock
Was gonna do the Amazon motor you got and 36V 20 AH Battery
I’d like top speed to be 30 but long range… any info would be great!!
Btw he has a Raptor 250 with experience, I just don’t want him going fast on the streets
I think you’d probably want to go for a 48v battery with a matching motor/controller - I don’t think there are any good 36v options, and the power upgrade just wouldn’t be enough fun :) Here’s a pretty affordable 48v 20ah option that should get you really good range: amzn.to/3CVZMEh
48v kits on these bikes are great, and with a 12 or 13 tooth front sprocket from Electro and Co he should be able to hit 30 no problem! Vevor makes a 48v kit similar to the 72v one I used - you can also find that on amazon and it’ll give you around 2kw which would be perfect for a younger rider.
Im probably going to do this exact build but does anyone know how long the bike will last until it dies?
Really looking forward to watching this, but the video motion just sucks too much. We just got a 3.6KWh 72V battery for our 8KW Suzuki project and I was hoping to learn things to apply. Sad...
video motion? like the motion of the camera? I’ve toned it way down in recent videos, never even realized I moved the camera so much until someone pointed it out to me. sorry this one wasn’t too helpful for your project, it sounds cool :( hoping my future videos can help!
@@logan-taylor Yep, the hand-held parts and my tired, aging eyes/brain just hurt from it. Even the helmet video is okay for me. Sorry for the "suck" because your content's great if I can deal with the video motion. This is the first of your videos I recall, but I've subbed in hopes. Great work and good to learn from the static shots, LOL.
Oh, and watching further, you're using a similar battery to the one we got today! 72V, 50AH, 80A BMS and it's the largest battery I've owned. (I've worked w/larger on ships, but they were lead acid. This thing scares me.) We're welding a casing to hold it into the GS500F frame this weekend. It's a hefty chunk 'o Li!
The SM200SP controller and hub motor can handle much more, so this battery may move to a Honda Ruckus project sometime in 2023 or so. Thanks for the reply and I'm looking forward to more.
@@jameswyatt1304 keep me posted on that electric Ruckus, that’s a project i’ve always wanted to tackle since i was like 17 - sounds so fun.
I've got 72v system in Dallas love it but I own 3 lol Razor mosiah of Dallas 😊
what would i need to wire the battery
What gearing are you running? You want to get a 13 or 14 tooth front sprocket. You’ll lose a hair of that torque, but gain top speed; and it will still lift a little.
Also, as others stated, E&C programming does help. You can get the mapped controller for about $350.
Razor didn’t know what they made when they made these. The SX/MX500 is the best frame, as it is the most versatile. You also have, with the SX, a real BMX freewheel; so you can upgrade (ACS Paws 4.1 is a great mix of price and performance).
You are just getting started. These are little speed drugs.
Running a stock 11t in front, although on the hunt for a 13t to try it out -- such an easy thing to swap out, so I figure it's worth a shot!
A kelly controller is 100% on the horizon now that my second round of upgrades are done :) (video coming this weekend).
I was actually so curious what the best freewheel option was but couldn't find any information. Thanks so much, I really appreciate it!
Speed drugs indeed. It's addictive.
@@logan-taylor Check out KruseN Stuff. He’s been messing with a lot of gearing. He just hit 55.3 on his MX650.
With the ACS, you’ll first have to pop that cutting cherry; and remove the stock freewheel. Some people have been able to manhandle it with a lot of torque; but most hack it to death until surrender comes a’calling. You’ll also have to remove a small amount of material from the inner ring of the chain wheel. Completely worth the effort; and it definitely helps to make up for the last few generations’ lack of Hero’s journey. While you’re Doped up on Mod Balls, you might as well buy a 65t chainwheel. 55t is next level; but now you’re adding fans; check the_sharks_cove for his 3D printed fan shroud. Get 2 good 12v fans, and, if you haven’t already, spring for a buck converter, or just as good, a 110ac to 8A DC wall adapter (our Lord and Savior Bezos provides that as well). Works as good or better with 72v than the dedicated 72v to blah blah bucks. You’re gonna want to bedazzle that bish with lights, sirens… heated toilet seats. All’dat.
Would you believe I’ve run my mouth this long, and still haven’t got my own SX done yet? I’m in ecstasy just learning about the circuits and rewiring throttles, fans, brakes, etc. ‘Twill be a sexy, Baby Moto, ‘doe; and as close to street legal as I can get. Gonna try to Manifest a Registration. I truly believe if we demand the Right to Ride Responsibly, we can send K’ren back in’na’house. Y’feel me?
Ok. I’m exhausted.
That is way to much power and torque for a child 😮
Need to go with electro and co that's the kit I got
When you get the cheap controller you get the cheap feel. Grab a kelly controller and your set
for what it’s worth, the cheap controller makes it pretty hectic and fun. But yes, it was a temporary gap stop and an E&C tuned kelly is coming soon :)
What did you do with your old motor and speed controller and batteries that was on your mx500 if you want to sale it all im interested in purchasing it all
if you’re in the seattle area message me on IG! @loganandrewtaylor
Just wondering about what was the range when you upgraded it like this I’m planning on getting one and was wondering the range
i think i made it about 27 miles when i tested it!
@@logan-taylor ok thank you
Has anyone found another battery with the same specs in stock?
extended swingarm would make it more stable but thats fuckin nuts
Question could this power my yz80
How many mph it goes?
How much watts are is the battery
Would it work with a sx350
How much was the total build
How much is the kit gang?
You need full leathers. Better yet put that motor, battery and controller into something with a couple more feet of wheelbase.
1. i agree 100%, protective gear is in the works so i can participate in ride outs with the seattle PEV groups
2. if only i knew someone who could help me weld up an extended swing arm…
@@logan-taylor That's one way, you might know someone...😉
are you guys from seattle ?
we got like 10+ ppl in our group.
yeah!! That’s sick dude. shoot me a message on IG if you want to organize a ride some time! IG is @loganandrewtaylor
Needs a wheelie bar.....FOR SURE lol
hahaha u right
Can u do this on a go cart? That would look awesome
i’ll see what i can do
Need to make your own kits with this stuff and sell them cheap then other dudes, you know that everyone would go your way because it’s cheaper and pretty much the same damn thing
one day…
Next time put a cookie cutter on the back so it don't do wheelies.. looks fun either way..👍
can these parts work on different bikes? or does it only work on the sx500
It depends on the other bikes I know for sure if will fit on the mx500, mx650
Does this work for a rider who is 6'1"? Or will it be too small?
i’m about 6’3” so it should work great!
How tall r u bc i was thinking of getting one but im scared im too tall for it and my knees will be like way to uncomfortable
i’m just over 6’3”! It’s small but surprisingly comfy for tall people
Why did you custom drill a new hole in the motor bro? Jw.
That's so that the bolt can sit flush with the motor, otherwise I think it interferes when you try to mount it to the bike!
the link that you put for the controller and motor is only 48 volts
ong i bought it on accidnet
With a Kelly or far Driver controller it won’t jump on take off. The Vevor controllers do that
100%, I swapped to a Kelly KVD in a video shortly after this and it made a world of difference - should have done that from the beginning.
What is the black thing you have in the battery that you heat up
What’s the black connector you have in the battery that you heat up it didn’t come with it
do you need anythign to have this and ride it anywhere like i seea lot of youtube videos where they have this or the new modles and they and parts but like they never talk about the other side of this like if you need a drivers licence or anything like that cause it this this would be cool but i dont wanna buy anything and then cant ride it
that’s a great question - I can do a video on this, because the laws are a bit confusing. If you leave a Razor stock, it is legal to ride like a bike most places (but not all) but it depends on your state. That’s not legal advice, just what I’ve heard :)
@@logan-taylor thanks yea its hard to watch everyones videos of them haveing fun but never talk about the legal side about them cause it would be sick to ride them around where i live but i would just have to look up the laws about them in my state ig
A lot of larger riders extend that rear wheel so you don’t end up flipping off the back…
Hi Logan. Please provide the link to the helmet you are wearing. Thanks
Sure thing! I have a kinda moderately big head and wear a size large: amzn.to/3wRx8jG
@@logan-taylor Thanks bro! I recently modded my mx650 to 72v and that thing is insane, same as what you're experiencing 🙂
no way!! Congrats on the build, these things are so fun it’s crazy - definitely worth picking up a full face helmet lmao
Where is the link???????
Beef up that rear spring you'll have less lift up
would be nice for you to add links to parts you used in this video
just pinned the comment with all the links!! Let me know if I forgot anything
How tall are you? Thinking about building one of these but im 6’2”
i’m about 6’3”ish, we fit surprisingly well actually haha
Where can I find an in-depth on how to do wiring
Shoot sorry I didn't go more in-depth - I had to sort it out from the wiring diagram. If you're having trouble with your wiring shoot me a DM on IG (@loganandrewtaylor) and I can help match up the wires. Most of the time I just kind of guessed and it worked haha
nice job! how do you like the electronics and battery? safe as american made?
so far so good! The battery is a Lifepo4 so not as heat-prone as regular lipo (supposedly) and much less likely to cause a fire or something. Everything else has been working great, running at a true 72v, although i might recommend going for a slightly higher end controller - the touchiness of this one down low makes it a bit sketchy (as you could probably tell) but once you’re moving it’s all good.
@@logan-taylor ty. appreciete the info. looking forward to more of your vids with your razor!
thanks so much! next episode this weekend :)
whats the range
Extend the swing arm like 6 in
What is the top speed with all the parts on ?
Experts in the field only know of a minimum operational speed. There is no top end....
Not sure if you know this, but the batteries usually come from the factory almost dead.
definitely - this one came surprisingly charged up, but I really should have charged it 100% before the test. I was too excited to ride :)

@logan-taylor just figured I'd let ya know. I'm going through the rest of your videos now and see that you've come a long way. 😊 I started playing with these about 2 months ago tops. I now have 5 bikes and a electric mini go kart. I can relate to almost everything you're feeling in your videos. Brings me back to the first month of riding. I'm only on 48v but it rips wheelies just like your 72v. I soldered all my connections and I'm running my 48v controller at 60v. I need to make some videos of it and post em up.
dang you’ve got so many i’m jealous!! Definitely make some videos I’d love to check them out. Nothing quite like that first ride!
i have done something similar to him, wired everything in and it didn’t work and am wondering if it’s that the battery is dead?
How long does the battery last?
range test coming soon 😈
Do big wheel kit .
like bigger wheels or wider?
Taller 1s
@@jackfrosty79ify I'm going as tall as I can the video after next so keep an eye out
Just wondering how much was it all
I believe my budget for this entire build was like $800 (a lot) but if you did a 48v kit and battery, which would still get you 2000w, you could do it for MUCH less
@@logan-taylor how much slower?
@@Greenslimegaming11181 48v kit 25-30mph depending on weight
@logan-taylor the battery linked is now 800$ lol like wtf I'm buy that kit
Would this fit in a mx350
not quite sure, i think they have a smaller (narrower) motor BUT the bolt pattern might be the same! Probably the toughest part would be fitting a battery, mine barely fits in the sx500
