Nice job man!!! I love the CAD designed and/or modeled parts aspect of the build. I came straight over from the MXA video and like what I’m seeing. Gonna more of wucha got. 🤙
Actually working on one of these conversions. Picked up a RM 80 disassembled, bought qs138 70h, fardriver 72680, amorge 72v battery. Should be around 16-18kw.
12kw-16kw is really all that's needed for an electric dirtbike, they're pretty much unmanageable at higher outputs, my bike is 10hp, & puts down 371ft lbs of torque, & a 0-60 in a hair over 4 seconds. 😂 I got a Rwarr Mantis, so I can ride it legally on the road, it comes with a M.O.T & vin to be registered in all 50 states.
It is very close to being done, just have to wait on battery. I put a battery from one of my other bikes in it and am running 4kw @ 48v, but the new battery (72v 40ah) will be able to support 25kw (33hp)
This is amazing! Is there any way i could check out your Cad work? Id like to 3d print some of these parts to wrap my head around their design. I plan on doing a similar build soon once i find a good donor candidate.
We talked at the race about hinging the battery box. You could also consider putting the bolts in the battery cover and the a captive washer to keep it in place when you remove it..
I just bought a DRZ125 for an electric build. I was wondering what size bike this is in the video. Also wondering if you would be willing to share cad for motor mounts
Understanding now that the Stark I have on order is 260 lbs, I'm considering a DIY project. Thinking a 2017-2019 KTM 125 or 150 roller with the PDS rear suspension, the PDS allows for lots of room available & is simple. Those are pretty light chassis, likely similar as your RM in weight. If I have a target of 220 - 225 lbs gross weight & knowing what you do about chassis, battery & accessory weights - what size battery do you estimate I could use to maximize run time & stay under 225 lbs ? Thanks ... great build you have there !
Thanks! You should be able to fit 45ah at least and still keep it under 225. That should give you 45-60min of run time. I thought it was more like 240lbs? 260 would be pretty heavy.
@@electronracer Yeah, new Stark specs state 260, although they have updated the battery to more efficient cells & 6.5kw. 45 min to an hour just isn't enough for our 25mi loop of almost-hard enduro & there's no opportunity for a battery swap. I'm likely gonna take delivery of the 6.5kw hr Stark & see if I can live with it in the tight stuff & step descents. Apparently there's no free lunch when it comes to run time VS gross weight.
looks awesome man, how much did the whole build cost in total? and is it also possible to use any other 72V li-ion battery or does it specifically need the one listed?
Hey just started my own conversion on a yz 125 and had a couple questions. What would you recommend for a power switch and volt meter? I appreciate the help!
Thank you! Last question, what's the average ride time for the batteries you selected and hp? I'm hoping to start building within the next couple weeks
What’s everything you need to make it all eletric I am trying to make my yz 65 all electric, I know you need motor battery and controller but what other wiring will I need? Sick bike btw
Great job, congrats!...The setup of 16 Kw, it is optional setting in the controller? Means, no re programming or etc? What the max Kw in this Votol EM200...since I am reading in their website 5Kw? thanks
Thanks! Yes you can adjust the power in the controller settings. The EM200 can do like 22kw or so max. Larger controllers like the EM260 can easily do 30kw+.
Hey man just subscribe because of the proper job you did in realize this build! I would like to ask if you made the CAD model of the motor or if you got it somewhere. Because I would like to start my project based on that motor, and the cad file will be fundamental to start. Thank you in advance for the info 😊
It was a good fit for this. The motor is nice and light and can deliver a lot of power. My bike isn't as fast as a 250f but it could be close with a bigger controller and battery.
DOPE! I have a ktm 450 with a broken 450 motor and you did exactly what i wanted to do to convert! does that motor come with a gear reducer on the end?
I'm doing a similar build with a 2012 rmz frame same motor em260 controller. I was going to mount the controller the same way. I noticed the spacers you made. I need to make something similar for mounting. Is the mudguard custom too?
@Electron Racer would you mind sharing your design. I can also share with you qs138 motor mount for cnc and also made a front sprocket/chain guard for the qs
Just curious but what’s the limiting factor at this point (besides $) for people doing their own builds and being able to get crazy 450 or better type power out of them? Is it available/scalable battery power, available speed controllers to handle high power motors or finding small yet powerful enough motors???
You could crank up the power. The battery usually becomes the limiting factor. I'm using a smaller/lighter battery. Some people have built them with much larger batteries and more power but they get heavy.
@@electronracer I was going to use a DRZ for my build but I just picked up an YZ85 roller. I 3D printed the QS138 and looks like its going to hang out by the foot peg a little but I'm gonna see how it turns out.
Very cool I just bought 2700 used cells plan on building a rm85 e ! Thanks for the information in description the qs motor seems to be the way to go ! Did you have any issues hooking up the controller ?

Hey! Good to hear from you. Yeah that's a good idea. I might try something like that. If the bolts were held in somehow that would help.
sweet ...cant wait to convert my kx250 smoker ....
You should mount a 2nd battery under the rear fender, or maybe move the primary one there.
Nice!
Very nice build. How long does battery last on track?
Thanks! Its good for about 30 min of hard riding.

What a machine, if she'll last 30 mins on a track Hammering it she'll last a good Hour cruising the streets at night ⚡💯🤟🇺🇲
Thanks! Yeah it's good for almost an hour of easy trail riding.
Great job man! How much km you ride on cross with this battery?
Thanks! Depending on how hard I am riding I can ride about 20-30km on each battery.

Hey! This is the volt meter I use: www.amazon.com/gp/product/B08L8RDW17
Hey just curious where did you purchase your batteries? How much did they cost?
I get mine from Amorge in China. They are about a grand each after shipping.
Thank you! Last question, what's the average ride time for the batteries you selected and hp? I'm hoping to start building within the next couple weeks
Cool. What motor did you use?
QS138 V3 Motor. Parts are listed in description.
What’s everything you need to make it all eletric I am trying to make my yz 65 all electric, I know you need motor battery and controller but what other wiring will I need? Sick bike btw
A throttle and some large wires for connecting the battery to the controller. That's about it other than the mounting hardware.

How fast do you think it will go??
Is it a full size bike? It will be underpowered with that setup.
Nice bro! I was wondering if your kit would also fit an 06 RMZ 250f ? Thinking about doing this
Thanks! No, unfortunately its not a direct fit for that bike.
What cad software/app did you use for the mockups
Solidworks
Hey man just subscribe because of the proper job you did in realize this build! I would like to ask if you made the CAD model of the motor or if you got it somewhere. Because I would like to start my project based on that motor, and the cad file will be fundamental to start. Thank you in advance for the info 😊
Thanks man! I got the model from the manufacturer. Shoot me an email at info@lithium-king.com and I'll send it to you.
Good times.
Hey man! Why did you decide to use that controller/motor instead of the more powerful one? And how does the power compare to a regular 125 or 250f?
It was a good fit for this. The motor is nice and light and can deliver a lot of power. My bike isn't as fast as a 250f but it could be close with a bigger controller and battery.
How many inches are the wheels?
Hi, what kind of throttle are you using?Can the Domino one works with the Votol ?
I use the Hirschmann e-Throttle. The Domino should also work fine.
DOPE! I have a ktm 450 with a broken 450 motor and you did exactly what i wanted to do to convert!
does that motor come with a gear reducer on the end?
Thanks! Yes it has built in gear reduction. Great motor for this.
Nice! Does it run for a long time with this 72v33ah battery!?
About 30min of hard riding, 45min+ of easy trail riding.
@@electronracer thanks, not bad at all! 👍 I do the same with my surron I think lighter than yours.
I'm doing a similar build with a 2012 rmz frame same motor em260 controller.
I was going to mount the controller the same way. I noticed the spacers you made. I need to make something similar for mounting.
Is the mudguard custom too?
Nice! The EM260 will work great. Yes the mudguard and controller brackets are 3D printed from TPU rubber.

Magnifique , ont peut commander sur qu'elle site ?
Thanks! Lithium-king.com
How did you go about getting the frame model into cad?
I just measured it manually, modeled up the mount points, then built around that. The image is used as a guide.
Just curious but what’s the limiting factor at this point (besides $) for people doing their own builds and being able to get crazy 450 or better type power out of them?

You could crank up the power. The battery usually becomes the limiting factor. I'm using a smaller/lighter battery. Some people have built them with much larger batteries and more power but they get heavy.
Main obstacles are skill and money. Getting the right battery is a challenge for most to do 450 power.
How to buy battery bro
What size bike is that?
It's a full size MX bike. An RM125.
