Modified Razor MX500 to adult sized MX750 See my blogs in RCPlanet. My handle is needspeedjoe and my posts start around page 41. www.pocketbikeplanet.com//show...
and i'm getting a kick out of all the haters making comments about real dirtbikes(which are totally different project and ride compared to each other,along with the finances and mechanical work required to disassemble and assemble..they just dont know how easy electric things work i guess..lol
Love the stance of the bike. It’s sick looking. I Purchased a DNM DV22AR -200mm shock on eBay for $45 fit perfect and added 3.5inches of ride height in the rear. Thought I’d get more out of it height wise but Any longer and I’d have to do the front upgrades.
Nice Razor bike! I love these things! I have had 3 of them so far! Twin Ryobi 40V bats on my current build. I'll be posting a video on it soon. Cheers!
How did u wire up the extra rc battery switch. Guessing dtdp switch with negative from first battery to negative on controller on one end and negative to positive of rc battery which is then someone connected to controller neg. Can u help me out
RCengineJoe, how did you wire the R/C battery and boost switch to the main batteries? starting from where in the main batteries 48volt loop and ending at which battery in the main 48v loop? i built one and followed your steps for suspension and seen your boost button and now im trying to get more top speed out of the bike also..
Love this and i will be doing the same very soon. maybe not the power mod right away but getting it to be adult size first. What shock did you use? i was thinking of just getting a shock riser fr now and see how that works. They make pit bike handler bar raisers also that i will be using. I want mine to be has clean as i can get it. I like the look of you not putting the engine covers back on. I wish you have a build VLog. I won't have mine for a few months but ill share pics with you when I'm done.
I got one of these when I was like 10 or so but stopped riding it because it was starting to have some things break but now that I just turned 15 I was thinking a fun project would be to revive it and modify it to be taller and faster like this
JeraldThe key here is to use a double pole double throw switch. I suggest Googling this if you are not familiar with it. Basically when the switch is thrown in one direction, I route the stock 36v or 48v through that side of the switch. When the switch is thrown in the other direction, I route an extra 11v to this side of the switch. On the battery side, you need to split off of the last battery and wire in your connection to the extra11v battery in series. This is the side that goes to the second pole and throw of the switch. Hope this helps.
in between one of the battery leads. you cut a power wire and add the shunt. usually on the china meters its the negative one. look at the schematic you get with your meter, on the ebay page, or on the back of the meter itself.
j92s1 www.ebay.com/itm/132097846668 Grind off the base, countersink the rear two bolts, and move the power cable to a different vent hole. Drops right in.
j92s1 No problem, post a video here when you get it in! Sit forward on the seat.... It'll wheelie easy. Run 72v on it. It'll take 100v easy. 4kw for me just gets it warm. prob 58c.
Thank you so much for this video it was very helpful can you please let me know where did you purchase the 9 inch shock and If you have the item number and model number that will be great
Can you please let me know Where did you purchase the 9 inch shock and if you have the item number and model number that will really help thank you so much for this video it was very helpful
J Flores Go to pocketbikeplanet.com and search for my handle "needspeedjoe" and you'll see lots of info on my bike and others. Good info here and I recommend reading some of it. My lists start on page 44 or so.
RCengine Joe - Very Cool! Question: Do you think the original 36 volt speed controller prevents your new bank of 48 volt batteries from getting fully charged? I am doing a rebuild of my sons MX650, and I was going to replace the speed controller with a new 48volt controller but if it is not necessary that would save me alot of time.
I used a double pole, double through switch. If you are not familiar with electric circuits, you can Google this. I would also suggest mocking this up on a smaller scale using AA batteries and a small motor etc. until you get familiar with the circuit.Basically, I have a Y harness which comes off of the +side of my 48 volt series batteries, One side of Y harness, goes to one side of the switch and the output of this goes onto the motor controller (keeping everything at 48volts). While the other side of the Y harness goes to the other side of the switch and the output of this is wired into the 11.1 Lipo harness (Harness allows you to unplug and plug in the battery. This adds the 11.1volts in series with the remaining 48volt series circuit, making the total 60volts ). I doubt you can use a push button with this setup unless you can find a double pole button. You may be able to devise some other circuit for this. As for the switch, make sure you buy a switch for electric scooters which can handle the voltage and current. Monster Scooter should carry the double pole, double through switch.
RCengineJoe so basically once you are going after 5 10 seconds you switch it on to go faster and if you turn it on when you accelerate you will blow something right
Hi this is awesome!!!! Is this for sale? We are from the philly area. My son has a 1000w 36v from Santa and I would love this to ride with him around the neighborhood
I sold this a little while back. Check out the link in my description for building your own. Building is part of the fun and you can learn a lot with your son along the way.
Simon Tran With very conservative riding I can get 5 miles or about 25-30 minutes. If I ride hard (full throttle much of the way) I get 20 minutes and 4 miles. Can NOT run this full time using boost.
+Jacob Phelps Yes, you can do that. The real work here is adding more batteries in series if you want more speed and of course that work I did on the suspension.
The motor is rated at 36volts but you can over-volt these motors. Its not the voltage that maters so much as the current. The motor is rated at 750watts at about 21amps (v=p/I), 36volts but you can safely take this to around 1100watts by bumping up the voltage. The speed controller is the limiting factor for the current output. Larger speed controllers which dump more current can quickly fry these motors. I say stick with 48volts and the stock controller. I boost to 60volts but only when the motor and bike have reached about 15mph.
Thanks. About how fast can you go with just 48 volts and no boost? I was thinking of doing this but if I get an ok speed without the boost I would do that.
Not at all - 4 heavy threaded steel rods holding it in place. Never had an issue! Plus, I perform regular maintenance on my bike to make sure all bolts are always tight and secure.
Some one asked for a parts list a while ago but it looks like you comment was deleted or something and I know this is a old vid but can you give me a parts list if you can and where you got them
+Adventer man You also need to pay attention to the mounting hole size/location and the specifications of the shock with regard to weight. I'm big so I needed a 250lb-300lb shock. The first shock I ordered would bottom out so I had to buy another.
+Adventer man Here is the shock I used: www.ebay.com/itm/DNM-Mountain-Downhill-Bike-Coil-Rear-Shock-750-lbs-230mm-/161106441123?pt=AU_Sport_Cycling_Parts&hash=item2582b133a3
+RABID BARBARIAN You missed the point! Half the fun is building something and tinkering with stuff to make it better than it was before. What can you do with that 50?
Not true the mx500 has longer length measurements than the 650 in online showings. The 650 is 45.5 inches long while the 500 is 46.5 longer. It doesn't make much a difference but I just thought I would say that.
Only real difference is the motor, 500W Vs 650W. Same controller for both & both are 36V stock. You can drop in a 800W motor for slightly better performance on either bike as an easy 1st mod.
Many city's turn their heads to electric scooters because they are quite. Run around a on a pit bike or full size dirt bike you ate going to be asked to stop or worse. Half of us have motor cycles but also have kids to ride around with!
O.G.alex Not all states allow u to ride dirt bikes on public streets unless they are registered and have blinkers,brakelights etc. That's why an electric bike is perfect.Nothing needed and very quiet
This is probably the best mod I have ever seen on a razor mini bike
and i'm getting a kick out of all the haters making comments about real dirtbikes(which are totally different project and ride compared to each other,along with the finances and mechanical work required to disassemble and assemble..they just dont know how easy electric things work i guess..lol
I agree, you get it or you don't !
Man I was just saying how it would be awesome if razor had bikes for us older dudes, I wanna ride around with my son haha awesome project
Great video bro I'm into this type of stuff don't listen to the negative ppl out here some ppl out here still like too learn about this type of stuff
Love the stance of the bike. It’s sick looking. I Purchased a DNM DV22AR -200mm shock on eBay for $45 fit perfect and added 3.5inches of ride height in the rear. Thought I’d get more out of it height wise but Any longer and I’d have to do the front upgrades.
Now that guy is the man and his mods to the mx500 top all others
Mine does 30mph at 48v, and soon will make it 52v lithium. Nice video 👍🏼I like the display and rear light
Nice Razor bike! I love these things! I have had 3 of them so far! Twin Ryobi 40V bats on my current build. I'll be posting a video on it soon. Cheers!
I love this. If I can get one of these bikes cheap I'd do the same thing to it. Looks sweet!
This is great. I got so many good ideas for my 500
all bikes are fun e-bikes motorized bikes scooters skateboards go karts mopeds put wheels on it and zoom
So cool!! Love that boost option
How did u wire up the extra rc battery switch. Guessing dtdp switch with negative from first battery to negative on controller on one end and negative to positive of rc battery which is then someone connected to controller neg. Can u help me out
You need a new 48volt charger to charge the 4 SLA batteries and a separate charger for the extra boost Lipo battery.
Could you show your wiring diagram for the overvolt system you have in there?
Where did you get the rear shock from and you said it was a 9" shock from a 6"? If I raise the rear do I have to raise the front forks like you did?
Yeah id also like to know which shock was used
Thanks for sharing this video review! NIce upgrades !
I respect what your doing I just hate the batteries man
Nice to make something and proudly ride it.
How exactly did you add the pipe fitting to the front fork?
Thanks for the great walk through.
What shock did you use can you post a link?
RCengineJoe, how did you wire the R/C battery and boost switch to the main batteries? starting from where in the main batteries 48volt loop and ending at which battery in the main 48v loop? i built one and followed your steps for suspension and seen your boost button and now im trying to get more top speed out of the bike also..
Read down into the comments. I posted this in the past for "Donald P". You will need to expand the comment since it is fairly long.
Great proyect men congrats
Is there a wire harness you can but or did you wire all the battries yourself
Love this and i will be doing the same very soon. maybe not the power mod right away but getting it to be adult size first. What shock did you use? i was thinking of just getting a shock riser fr now and see how that works. They make pit bike handler bar raisers also that i will be using.

I won't have mine for a few months but ill share pics with you when I'm done.
Hey man do you think I could get a wiring diagram on the 48-60 volt boost switch? I’m in the process of building a bike for my son .
How much would it cost for you to upgrade my Razor Mx650?
I got one of these when I was like 10 or so but stopped riding it because it was starting to have some things break but now that I just turned 15 I was thinking a fun project would be to revive it and modify it to be taller and faster like this
What I would like to know is how you wired that boost switch in I want to do that on my scooter I have but no success

Hope this helps.
I got a 52v lithuim battery with the 2000watt kit I am definitely doing these mods on my mx500.
Can i ask a question in regards to the Ammeter where did you mount the shunt and how?
in between one of the battery leads. you cut a power wire and add the shunt. usually on the china meters its the negative one. look at the schematic you get with your meter, on the ebay page, or on the back of the meter itself.
Where do you buy the 9inch shock to fit the swing arm and frame
Look through the comments. I've posted the link several times.
How did you do the peg drop?
I just did a tasty 3kw or so mod to mine. 72v brushless. Drop in replacement motor too!
4kw actually. Just did a test. gonna go to 5kw soon. Where'd you get your shock? The bike shops are trying to bone me @ $300+ One even wanted $850!
Link to motor?
j92s1 www.ebay.com/itm/132097846668 Grind off the base, countersink the rear two bolts, and move the power cable to a different vent hole. Drops right in.

How did you wire in the extra battery?
I think you can just CZcams search “razor mx500 mx650 48 volt conversion” and see some videos of people doing it
At 6:25 looks like u was going pretty fast👍
Can you do a parts list and where you bought and price? Thank You

I wish he showed us the boost in the video
Dude, we need to talk! Where are you located?
Do you have the part number or a website link for the rear shock? Thanks
Read down into the comments. I believe I posted this 2 times in the past.
@@RCengineJoe can you edit the description? That way it's super easy to find.
Can you do one for me? I would love a build like this one specifically. 🙏🏾
🔥🔥🔥🔥🔥🔥
you not gana make no links on the supply
How did you wire up the lipo and switch .......also can you add a push button instead of a switch

About 20-22mph on average. Its not a bad speed for such a small bike.
please help me i need mine taller
handle bar looks shaky
Not at all - 4 heavy threaded steel rods holding it in place. Never had an issue! Plus, I perform regular maintenance on my bike to make sure all bolts are always tight and secure.
you the fucking man
how tall do you have?
6'1", 210Lbs
How much you want
Echo friendly Bruh!
was wondering if you'd be interested in selling your bike?
Sorry, sold it a few years back.
top speed
wats the top speed
~30Mph top
I want that
How much you want for it $
Would you be willing to sell that
Sorry - sold it a few months back
Outdone by a 50cc
Some one asked for a parts list a while ago but it looks like you comment was deleted or something and I know this is a old vid but can you give me a parts list if you can and where you got them
I thought this was a old vid sorry I made an assumption
I put a car battery in mine
How well, or not well does that work for you since it is only 12 volts? How far can you go?
Not fast at all but he would able to go HELA far distance
Dissquished it can go about 3 ish miles idk I’ve never tried
so I could order a 9 in shock and just take out the old one and I would be fine.
+Adventer man You also need to pay attention to the mounting hole size/location and the specifications of the shock with regard to weight. I'm big so I needed a 250lb-300lb shock. The first shock I ordered would bottom out so I had to buy another.

Us adults get gas powered 125cc's and up.
It's cool though.
But it doesn't go the speed of even a 50
+RABID BARBARIAN You missed the point! Half the fun is building something and tinkering with stuff to make it better than it was before. What can you do with that 50?
built not bought
Do all that to a 650
The only difference was the motor and controller which he changed making it better than a mx650 anyway.
Ill give $700 for it
Sorry, I sold it just a few weeks ago.
just get a mx650 thats already bigger
Not true the mx500 has longer length measurements than the 650 in online showings.
The 650 is 45.5 inches long while the 500 is 46.5 longer. It doesn't make much a difference but I just thought I would say that.

There's no engine lol.

That shit is cool and all, BUT y not just get a dirt bike 😕
+Jacob Phelps lol u can do that with a real dirt bike that statement was highly irrelevant 😂😂

Joe Layva true
Just buy a mx650 it carries 220 pounds
Would 250 pounds be okay
He made a 48v mx750. Why would he want a weaker mx650????
Instead of wasting your time and money why didn't you just buy a real dirtbike
Max Masone true lol
Max Masone people don't have trails near them like me
You can ride a electric motorcycle anywhere because its considered a Electric Bicycle.
Young Maxp
Uh bc your parents won’t let u
Or buy a dirtbike
Illegal to drive on the street
It’s slow as hell!!
When you can build an ebike and also make it go faster than mine, then you earn the right to critique and my respect!!!!!
