At the moment im trying to build a razor sx500 with a 8inch swingarm extension and put 16” and 17” wheels on it and everytime im stuck i always come back to this video. This build is genuinely impressive.
Funny cause I was just thinking about picking up something from like the 70’s to convert into a cruiser! To be honest you can likely build a 65 or 50cc for similar price and have a better setup
By far one of the best looking builds! Would love to do a builds based off yours!! Not sure if you have a full list of everything you did and the parts. Would be awesome
Darn I’ve seen a lot of builds this thing is great! The throttle is awesome! The forks you fitted with brakes 😮! On off switch nice! I hadn’t seen those plastics with seat placement super cool. You are awesome! 5 out of 5 exclamation points😊. I wish you lived in Boise area
Thanks for the details im trying to build this style right now. Currently have the 6000w surronster kit on it with the 72v battery and a 9.5” shock and extended damping rods but need to get bigger tires extended swing arm and new triple clamp and forks. Just trying to make sure I get the right stuff
Yeah I agree, but my ratio is already super high! My next video of some off roading shows that the MY1020, just can’t much more than 6kw. Good little motor for what they are
Sweet build. I'm planning an mx650 build with a 5000w 17" rear hub motor wheel and 17" fronts. Without the motor a hub wheel should fit. I think it'll be the first. Im looking at the swingarm extension but not sure if it's strong enough. Might have to take some weld lessons.
So a stock razor MX 500 frame you can put the CRF 50 plastics and tool seat and they just bolt on no modifications needed?? Awesome looking build. I’m in the process of building a razor MX 500 pit bike do you recommend the extended swing arm? It looks nice
Yeah the plastics go on with very little work. Almost perfect. I certainly recommend a swing arm. They are pretty small bikes and that swing arm adds a ton of stability
Bag ass man I'm currently planning a build but will be making my own lithium bank out of toshiba scib 10ah cells because of they're extremely powerful C rating on there discharge and recharge and you can pull 1000amps of current just off 1 cell rated at 2.3v nominal it charges upto 2.9v I'll be running 21 cells In a series configuration and using a icharger for the bms,charging and monitoring of the cells temp and life. Love your build!
Sounds very similar to the SPIM08 cells! Nice! I would definitely recommend that and a better motor. Since this video I actually went to the EC4P and got a 72V 200/300 amp discharge. May go to the QS120 though as the EC4P isn’t playing nicely with my Fardriver controller now
@Nick's Garage Builds what are you using for your speed controller and you should look into those cells man there small and LTO chemical compound but they are nasty they are the scib 10ah made by toshiba and they put out a max of 75c rate! And will discharge upto 1000amps at 2.8v max and 2.3v nominal
They sound like a sweet cell! I’ve built some 18650 packs, but it’s a ton of work. I kind of want those for my next project though! Thanks for the tip My controller I’m running the Fardriver 72450 now. I like the controller ability so far
Kinda and yes. The added height is for sure more comfortable, but in order for it to feel slightly bigger you may want add some drop pegs. I’m about 5’11” and it still feels off from like an 85cc dirt bike.
So stock bolt is 12mm and this wheel calls for a 15mm bearing ID. You can go 2 routes. I personally bought a new axle and just drilled out my swing arm for a 15mm bolt. The other option I never tried would be to find a bearing that fits, but goes to a 12mm diameter. Bolt if you go 15mm bolt route amzn.to/3tA0zbQ Replacement bearings that bring it to stock 12mm size. Then you should be able to reuse all hardware.will need 2 obviously amzn.to/3RLHuLM
Great video bro really like the bike prolly the best build i have seen did great on the size using the 735 mm firks with the 14 and 17 wheels looks more like a real bike than most razors that still looks like a kids toy due to height and size. My question is you seem to be running the my1020 moto i am assuming 72v3000w what is you battery voltage i am in process of similiar set up but more of a supermoto style bike but am running a 60v 26amh battery with fardriver controller and 72v 1020 motor
I have since swapped over to the EC4P from E&C and running the Fardriver 72450. I had a 72v battery from Amorge lined up as well, but in the end I decided against it. Instead I picked up a yz85 chassis to mess with. But in short my battery is 60v
I made it myself with 4 pieces of C channel metal. A few guys in FB make them and do a much better job than I could regarding looks. My stuff won’t break, but I ain’t the prettiest welder
How did you add the 4.5 inch extension on the rear swing arm. I think that is awesome for the bigger wheel and i'm really interested and doing the same to mine. Thanks man I appreciate any input you can share
So with this one I used 4 pieces of C channel. I’m currently doing another one for my buddy and we are making a in depth video on it. We used another swing arm that sleeves inside and has rear chain tension adjusters. I like that setup way better
Hi I have two questions. First of all, where did you get the graphics for the crf50 plastics. And second of all, what controllers would you recommend over the kelly controllers
Those graphics are actually a wrap. I got the wrap off Amazon. I would say Fardriver for budget. I don’t have a crazy amount of experience in that many controllers yet. I’ve been reading good things about 3shul, but yet to buy
What was your top speed with your sprocket set up? I just set up mine with the same size tire and struggling with heating up the motor. Not sure if I should go 9t or 10t
I ran 9t for that very reason with that motor. I got around 28 I think. If you have the means I would go with the sotion or E&C motor. I don’t have any overheating anymore
@@NicksGarageBuilds ahh I didn't realize that . The build came out very good. I'll have to follow In your footsteps . I have one over volted to 72 v, the motor didn't last all but a week but it was fun, I have an 8hp motor ordered and a larger pack I built 40ah 72v. Was looking for better brakes and suspension and your build is perfect.
Like with rebound and compression? Mine have an adjuster at the top. Debatable if it actually does anything, but it possibly did. You kinda get what you pay for sometimes
Hi Julien and thanks for calling that out. I have filed a bug report with UA-cam, but it shows my verification as "pending" despite Google saying it's verified. The only solution I can offer is to copy the link and paste in a new window. Apologies
By the way that bike is actually sick if you look at CBRacing that’s my Chanel and me and my friend post videos on our razors but I want mine to be bigger
I don’t remember cost, but I bought that from electric scooter parts. However I would call Rebel Gears. They make a damn good gear and you can just provide dimensions if you have a custom wheel
Depending on what QS you get just make sure to get “hall sensor” type. I’ve moved on to Fardriver and I like it a lot. The ability to tune it much faster and easier. It also supports field weakening, which increases speed if you are interested in that
I took C channel and staggered the pieces for strength, (so total of 4 pieces). If I stretch another one I would probably just cut the bent pipes on the stock one and make my whole lower part from scratch. Also would add the ability to adjust my chain from the rear wheel like a real motorcycle.
Front forks are 735mm, (stock 550mm). Rear swing arm is extended and to make it match the front my rear shock is 220mm. Last was just adding a 17” front and 14” rear wheels.
I work with anything, but I’ve come to love electric toys. Regarding papers I have no idea what your local laws are. There are certainly no papers on my bike, but that may just be ignorance
So a couple of guys sell forks and many other things for razor. They are super responsive and I drastically appreciate the work they have done to help in the razor community. rodrandd.com If they don’t have what you need just ask them!
I cut the rails almost in half and cut the welds to the hoop for the shock. I than added a piece of Channel on both sides, 4 in total, and staggered them for strength. Than just welded it all up. If I did it again I would replace both lower rails with some 1x2 1/8 tubing and make rear adjustments for chain tension. This was my first attempt at stretching a swing arm
@@EthanMX08 I feel like you can’t go wrong with DNM RCP2 or JFOYH. I only like the ones with the small reservoir and adjustable. I personally am not a fan of the pneumatic downhill mountain bike shocks. I ride really hard on trails and haven’t ruined one yet, but I’m not exactly taking massive jumps either
Knowing what I know now cheaper. When we started doing this stuff like 2yrs ago we made lots of mistakes and everything had to be developed. I could build this bike again for 2k. I probably have closer to 3k in it
Hello, We have now upgraded this motor to better use with go-karts and off-road motorcycles. Do you need it? We can provide you with free samples for testing. 60V/72V 2000W-3000W 3500RPM 38N.m
At the moment im trying to build a razor sx500 with a 8inch swingarm extension and put 16” and 17” wheels on it and everytime im stuck i always come back to this video. This build is genuinely impressive.
Glad it helps!
Can you make a full tutorial I want to make this
Looks good, like the wrap. Your 17F / 14R wheel set really gets me interested in doing another build for dirt use..
Funny cause I was just thinking about picking up something from like the 70’s to convert into a cruiser! To be honest you can likely build a 65 or 50cc for similar price and have a better setup
@@NicksGarageBuilds where did you get the wheels from?
By far one of the best looking builds! Would love to do a builds based off yours!! Not sure if you have a full list of everything you did and the parts. Would be awesome
Obviously not the custom stuff, but other items are all in the description
Great video! I want one now!
Ah shucks you too nice
Gotta build one

HEY HEY HEY!! NICE WORK ! KEEP CREATING. Like the arm , great job w A LOT OF THIS. Suoer glad to see another person making!
Thanks man. It’s been a great learning bike! Excited to start some of my next builds
That looks amazing I really like what you did keep up the good vids my man
Thanks! Looking forward to creating more bikes and different electric projects.
Such a sick build! Keep it up brother felt like i was watching a natural youtuber!!
Thanks Brandon! I’ve watched a lot of your stuff as I just picked up a Mototec a month ago.
You need to change your gearing on the rear sprocket to 90t. Will help keep the temps down and less pull on the motor
Yeah I agree, but my ratio is already super high! My next video of some off roading shows that the MY1020, just can’t much more than 6kw. Good little motor for what they are

If you have the welder than you can always just fix it again! Got to start somewhere, you got this!
How did it go? What’s the biggest size to fit?
I'm starting my own ev-razor build. OldRusty one I've been holding on to
That’s awesome. It’s a super great learning platform. I’m about to tear my down and start on some next projects
Nice job bro!
Great video
Where did you get the swing arm suspension?
sweet bike!
Thanks!
Very nice build Nick .I’m also building a mx650 there very fun little bikes. Great video.
Thanks Chad! We need to ride soon!
@@NicksGarageBuilds Yea that would be great fun .
Looking good!

I certainly recommend a swing arm. They are pretty small bikes and that swing arm adds a ton of stability
if you are worried about your battery, eon lithium will make a custom battery to fit your bikes dimensions and they have great batteries
I have recently bought an Amorge battery. Seems like a solid choice as well and you can customize also
Bag ass man I'm currently planning a build but will be making my own lithium bank out of toshiba scib 10ah cells because of they're extremely powerful C rating on there discharge and recharge and you can pull 1000amps of current just off 1 cell rated at 2.3v nominal it charges upto 2.9v I'll be running 21 cells In a series configuration and using a icharger for the bms,charging and monitoring of the cells temp and life.

My controller I’m running the Fardriver 72450 now. I like the controller ability so far
hey , love this build really giving me inspiration for my build. i’m 6ft would this still fit me?
Kinda and yes. The added height is for sure more comfortable, but in order for it to feel slightly bigger you may want add some drop pegs. I’m about 5’11” and it still feels off from like an 85cc dirt bike.
Sweet ! Just ordered the rear wheel
You recommended, do you know if can I use the stock bolt ? If not could you recommend what I’ll need. Thanks
So stock bolt is 12mm and this wheel calls for a 15mm bearing ID. You can go 2 routes. I personally bought a new axle and just drilled out my swing arm for a 15mm bolt. The other option I never tried would be to find a bearing that fits, but goes to a 12mm diameter.

@NicksGarageBuilds so your still running the 60v battery on the ec4p are you running the full 60v to it or 52v
60v is nominal voltage so at full charge it’s 67.2v. But yes that motor will run on anything from 48v to 96v from what I’ve seen
what chain do you have on there ? i’m building a 14 inch wheel with “the one” motor from electro and co and want to know what would fit and not break
It’s T8F, but I would use #35H at minimum. T8F stretches and wears too much
where did you get the swingarm?
I made it myself with 4 pieces of C channel metal. A few guys in FB make them and do a much better job than I could regarding looks. My stuff won’t break, but I ain’t the prettiest welder

Would you sell the parts you used a lathe to make in order to fit those front forks? I’ll be needing a pair as well but I don’t have a lathe? Thanks !
Would love to just never have the time! Plus plenty of folks now sell bushing kits
If i put a 17 inch front wheel on mine with upgraded forks, will the wheel hit the frame or fender if it bottoms out?
Depends on the length of fork. If it’s the normal 630mm forks, yes absolutely. I believe the ones I have are 720mm
What was your top speed with your sprocket set up? I just set up mine with the same size tire and struggling with heating up the motor. Not sure if I should go 9t or 10t

Nice build, where do you get the forks and wheels from? is this a kit ?
No kit just pieced together from Amazon. Lots of buying and returns lol. The links should all be in the description
@@NicksGarageBuilds ahh I didn't realize that . The build came out very good. I'll have to follow In your footsteps .

Yeah I’ve changed my setup since than for more power. Nothing crazy yet
wheres the swingarm from?
Home made. Just some c channel and welds
How did you adjust the front forks?
Like with rebound and compression? Mine have an adjuster at the top. Debatable if it actually does anything, but it possibly did. You kinda get what you pay for sometimes
@@NicksGarageBuilds Ok thanks
Could you link the taillight and headlight in the comments it wont work in the description.

How much was the 80t sprocket and can you send a link?
I don’t remember cost, but I bought that from electric scooter parts. However I would call Rebel Gears. They make a damn good gear and you can just provide dimensions if you have a custom wheel
What front spacers do you have?
I assume you mean spacers in the front wheel.
JRL 0.47'' 12mm 10'' 255mm Front... www.amazon.com/dp/B01N40OAOV?ref=ppx_pop_mob_ap_share
What rear shock do you use?
I have run the DNM RCP2 210mm and but now I use the JFOYH off Amazon. Nothing fancy as you are very limited in size
what controller would you reccomend for a my1020 72v 3000w motor but will also work for a qs motor in the future
Depending on what QS you get just make sure to get “hall sensor” type. I’ve moved on to Fardriver and I like it a lot. The ability to tune it much faster and easier. It also supports field weakening, which increases speed if you are interested in that
how many milimeters is the rear shock and fork
735mm front fork and 220mm rear shock
How do adjust the forks to make them softer?
My forks came with adjusters on the top. They may be fake though as it does t seem to make a huge difference. I may go to a lighter weight oil instead
I want to build one of these.. how much is to spend on the whole thing?
Knowing what I know now about $2500
What dimension steel tubing did you use for the swing arm extension?
I took C channel and staggered the pieces for strength, (so total of 4 pieces). If I stretch another one I would probably just cut the bent pipes on the stock one and make my whole lower part from scratch. Also would add the ability to adjust my chain from the rear wheel like a real motorcycle.
how did you make it tall what is the lift kit im pretty sure you said it in the video but i dont quite understand
Front forks are 735mm, (stock 550mm). Rear swing arm is extended and to make it match the front my rear shock is 220mm. Last was just adding a 17” front and 14” rear wheels.
@@NicksGarageBuilds thank you #
where can i buy the forks adapter to fit for the razor
I know Ride or Die R&D sells some
What foot pegs are you running?
Cheapie off Amazon. You will need some spacers to take up space. I used the leftover plastic ones from hanging my TV.

GTA ahhh camo
Do you work with electricity only? Can I drive it without papers
I work with anything, but I’ve come to love electric toys. Regarding papers I have no idea what your local laws are. There are certainly no papers on my bike, but that may just be ignorance
will the 14in wheel fit without the extended swing arm?
Unfortunately not. You can’t even get a 12” in there without a small stretch
Can I use stock rear axle bolt?
Not with this particular wheel. Stock is 12mm this wheel is 15mm axle
how exactly do i install the forks if they dont fit like you said, or are there other forks that would work that you could link me
So a couple of guys sell forks and many other things for razor. They are super responsive and I drastically appreciate the work they have done to help in the razor community.

If they don’t have what you need just ask them!
@@NicksGarageBuilds do you think the stock suspension is good for a 120 pound rider
how did you extend that piece at the end
I cut the rails almost in half and cut the welds to the hoop for the shock. I than added a piece of Channel on both sides, 4 in total, and staggered them for strength. Than just welded it all up. If I did it again I would replace both lower rails with some 1x2 1/8 tubing and make rear adjustments for chain tension. This was my first attempt at stretching a swing arm
I can see why gas bikes being loud is safer for other people on the trails.
Yup I agree.
How did you lift it?
Added 735mm forks in the front and 220mm rear shock.
How do you adjust the forks??
Mine had damper adjustment screws on the top
@@NicksGarageBuilds mine doesn't, munst be nice?
You never know with these cheap forks. Some do and some don’t. I’ve seen where they change them as well despite buying the same set.
should i upgrade the rear shock?
If it’s stock absolutely.
@@NicksGarageBuilds what shock do you reccomend im doing the electro and co 11000 watt 76v 24 ah kit so i probably need something good

What lb shock
I typically choose 550. I find that 500 is just a tad light for me. I’m about 175lbs
whats the seat height looking like?
Sorry for the slow replay it’s right around 850mm or 33.5”. Somewhere between a 80cc and a 65cc
Would the rear wheel that’s 14 inches fit on the stock mx500
Absolutely not. You have too stretch to fit anything over the 10”
What if you remove the motor and use a hub?
hello what battery do you use?
Stock Surron battery. I wouldn’t recommend
How much would you estimate the total cost to be?
Knowing what I know now cheaper. When we started doing this stuff like 2yrs ago we made lots of mistakes and everything had to be developed. I could build this bike again for 2k. I probably have closer to 3k in it
Super cool build!
Thanks!!
Did you have to modify the frame to fit the surron battery?
Nope, it just barely fits
my1020 3000w is better i think it wont heat up
I blew that motor up pretty quick too.
is it rain proof?
Technically no. I will say that I have rode in rain with zero issues. I just wouldn’t continue to do so
Dude? WTF get back in the garage and make and electric dirt bike from a 250 gasser.
lol I know right. Been working on a Golf Cart Battery startup. I love the electric dirt bikes, but the golf cart is just much more family friendly
