- เผยแพร่เมื่อ 13 มิ.ย. 2024
- Decided to convert my 2006 Yamaha YZ250 to a 72V Electric Dirt Bike. Since the original 2-Stroke Engine was getting tired and needed a rebuild soon anyway, I pulled it and installed Electro & Co's QS138 EMX V3 Kit along with an Amorge 72V 40AH Lithium Battery. With a 350-Amp ANT BMS and a Votol EM-260 25kW Controller.. this bike should be putting out well over 20kW! This video sums up my 10-Part video "Project YZ-E" build series start to finish. Hope you enjoy it!

holy hell man that thing is nasty!
I have to give you 100% thumbs up bro!!!
Even though your access to fabrication equipment is limited, your determination, and desire to Get-R-Done is AWESOME!
NICE JOB!!!
I've been contemplating doing an old RD250 conversion instead of restoring the engine.
If and when I do I will have to get you some pics.
I absolutely love this build !!! One of my favorite all in one conversion vids I've seen, making me really want to do it. Keep up the great work as always Pat!
Great video
Couple of small pointers.
Won’t use simple white foam but use Yoga mat. Much more dense and doesn’t break (squash) down.
Also the controller heat sink really shouldn’t be covered and needs air flow. If you cut the bottom of the air box out. Cover the heat sink with a aluminium plate (use thermal paste between the two) to act as a semi perishable stone guard and let air free flow over it.
Very educational and fun to watch. Your "level of expertise" creates a very good balance of creativity and caution...
Those boots 👍
Excellent video of this electric conversion! A couple tips: I would have gone with a steel battery tray, or completely weld together the one you built... that's one HEAVY battery.
Also it would be good to isolate the battery from the metal edges, as well as the bottom of the battery. It's not going to happen after just a couple of rides but eventually the vibration will cause the metal to wear through the plastic battery. A steel clamp, instead of that lashing strap, around the battery will eliminate 99% of vibration. I personally experienced the result of using a lashing strap instead of the metal one that disappeared from my quad while riding through the woods. The battery tray was plastic and the vibration still wore a hole through the bottom of my battery after just a few weeks.
I’ve watched the other build series of this bike and I have to say great job on the editing and videos all around in general. This channel deserves many more views then what it gets, I’m sure that’s coming in the near future keep it up
needs least a 100k youtube thing
Help get me there and I will 100% double up my effort and throw all my time into these projects!
You'll like this one if got one of those Chinese kids quads and a cr 80 engine bolts right in I'm going to post it you'll like it
@@PatOutdoors
Thank you for the video
@@christopheramoroso6801k
I got such a big smile on my face when I saw you hauling at 58MPH haha after all that work the reward is pleasant to see!
You may not be a fabricator but hell you did a good job for somebody did 99% of the work by himself
Good idea to wear safety glasses. I knew two guys who each lost an eye. One had a piece of cast iron break off (and fly up) that he was hammering on. The other was using a power nailer and missed the stud. The nailed came back to his eye.
Bro, this build is awesome! Holy crap it looks so clean. Good job bro, great content. 👍
Appreciate it!
Awesome. Really enjoyed the build. One of the best builds, thanks for all the info and simple explanations.. Inspiring... Great job..
Plastic kit would've been over $600 here in Australia. You guys don't understand how good you have it over there 😮
Yup us aussies get smashed hey
Why can’t you get it for the same price if your ordering it online like us?
@@stevethompson7290 because USD to AUD, + international shipping + import tax.
Hmm there's a buisness here somewhere...
Anyone got an electric boat?
Well you inspired me to start my own conversion. I just picked up a clean ktm 85sx roller for $300 and I just ordered a QS138 70h v1 motor to pair with it. Still figuring out battery specs and controller.
I am really thankful to you for bringing me up this interesting kit and inspiring me to build up my dream dirt bike! A couple of thoughts:
- At these power levels, the controller needs to be all the way in front, for air cooling
- If the battery is fully charged at 85.3V, this is 4.26V per cell. This is way too much, consider lowering it for battery longevity. The regular maximum is 4.20V
- I think, you really should consider impact safety for motor and especially battery. Looks like one hit to the side will rip out your battery. BTW does it come in a solid metal case? What did you pay for this 3Wh?
- weight of the complete kit and the battery would be interesting
- How does the controller behave? Can you adjust it to a certain fixed power, which it can do down to some low battery percentage? (e.g. 17kW consistently down to 20% charge, instead of 25kW at 100% but continuously decreasing during discharge)
Brilliant build, powerful too!!
Nice assessment of jdm skylines in Joseph's shop!
Man you did an outstanding job !! I am a welder and i was thinking how are you gonna mount that battery but you did amazing!!
Awesome video lots of detail very nice build I've been really looking into this electro and Cole I've been wanting to do this build to a old 86 CR125 I got
Im currently building a 2006 crf250r with a qs138 70h v3 and a far driver nd72850 i hope to push a little more power, thank you for such a detailed video this is super helpful!! Awesome work man
What's the cost of the conversion? Approximately
Hey pat just wanna say you came long way ' love content very helpful
1 Bad ASS Motor!! Cant wait to See it ALL Finished!¡
Great video, about to get my first 60v
Say hello to Brazil, im anxious waiting this tecnology to make my own eletric cycle
Melhor conversão que já vi em todos os tempos!!! Meu sonho impossível de consumo esse kit 😢
Awesome dude…thank you for sharing!!!
I'm getting ready to pull the trigger on converting a 08 yamaha yz250f. Debating whether I should go with your set up or do the qs138 90h watercooled version though. Pros on your build is that it seems that kit is easier to mount without too much fabrication
Awesome video! im going to be doing the same myself!!
Do it!
HELL YEAH PAT LOOKS GOOD!
You could mount the controller to the back-side of the radiators. If there is not enough depth you could carve out the radiators until it's flush. Or run what you got, it looks great!
Stark motor & controller will do
Top job! Well done 👍
I rode with you today i definitely need one of these !
Nice! Which bike were you riding? This is what I really wanted to ride yesterday, but figured it was out of place lol
Thats incredible. was gonna do my MTB as savage power. Now Im gonna get one of these 100%. go along with my hyabusa lol
Nice job on a really cool build/vision. I'm not sure how hot that controller gets, but I think I would have hard mounted it in the box without the foam around it all and then put a 6" fan in the front rather than closing off that air box. Sure hope there are more options for conversion kits that fit these types of motors into bikes. There is a huge market for tankless plastics and brackets. I'm really wanting to try to build a 300v / 15Ah setup with water cooling (to use the existing radiators) on my KTM 525EXC that has a motor that is getting long in the tooth...
Hell yeah! This was sick!
Nice build!
Thank you!
Pat now that you have run both of the QS138 kits from Ebay & Electro-C what would you say is the biggest differences in regards performance functionality?? Thanks man your vides have motivated me to take the plunge and make one my self...
💯💯👍👍nice 👌 I'll have to do one great Job man thanks for sharing 🏆
Cara , projeto muito bom !! Parabéns !!!!!
Nice build. Really inspiring me to try something like this myself. In terms of the controller, it needs to be able to cool down. I worry the foam you put in there will make it over heat.
Yeah I’m still monitoring temps rn, this build is not fully finished. Iterating over time to improve it
Someone else in another video mentioned to check the amount of oil that's in those QS motors cuz it's supposed to be like 50ml from factory spec but only had like 10ml in it.
I come from the world of modified razors so similar problems over here with the motors and stuff
Appreciate the tip! I'll check into the oil level with this one
I know this video is older, but you should get yourself a 6” cutoff saw. They’re like $40 from harbor freight, pretty small, and works great for things like cutting spacers. No grinder and vise required and it makes excellent straight cuts. Just a bit of deburring after and they’re perfect
Riding without footwear is bad. Silly looking ? Don’t care, been injured and seen many injured.
I saw a guy come off at speed wearing shorts and sandals , probably never ride again.
That’s a very nice bike. I’ve been wanting something similar, and have been waiting for a good similar factory built.
Good vid demonstrating your build.
Nice build! Have you had any issues with controller heat? Manufacturer website says bottom side is heat sink and you covered that side in foam. Perhaps you'll need some airflow / fins there if you want to push the bike hard. Location is still perfect for getting some airflow if you want to cut some vent / fan holes.
Thanks! Not so far, though this has been brought up to my attention. The airbox is not fully sealed, it's ventilated at the bottom and the sides. I'm still observing the controller at the moment before considering making changes.
How long does the battery last .How much time does it take on the road and how much time on dirt with uphill.the engine is capable of a long climb in the dirt
Thank you from Greece😊
Amazing video thanks gained a sub here
just ordered some battery from amorge. hope hes the goods.
Just a heads up the swingarms are painted. Since you had apart I would have regressed the bearing throughout the whole bike like the swingarm, linkage, wheels and headset.
Not sure that I agree with the recommendation for no display. Information is alway good. What settings options you have is a function of the controller you use.
On a super simple controller like a votol, there are much fewer options than on a Fardriver, VESC based, or even sabvoton.
QS loves controllers with minimal settings.
would like to see this upgraded with the sotion motor haha (i only say this because im back reviewing your video in hopes to take on a similiar project😂)
Does the controller get hot with no air flow and the foam?? I think I would not want any foam and unblock the breather hole
Best bike !!!!!!!!!! Thanks !!!!!!!!!!!!!!!!!!!! Best VIDEO !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I wish I could meet someone who has this kit. I wanna give it a shot for like 30 minutes and make sure I wanna spend almost 4k to build it
The Husaberg 501 .
If the centrifugal force of your electric motor is placed in the center of mass the gyroscopic forces could me minimized.
If the cells were arranged low and more or less wrapping around the motor , I'm sure it would improve the handling vs a high mounted square battery type cell. Just an idea.
The husaberg remains the best handling big bore due to where the weight and centrifugal forces were placed in the frame.
will any battery go well with the motor and controller kit?
Not sure if i would have gone the same route. I havent watched entire video. Nor am i going to pick it apart.Hopefully it turns out well.
How much did everything cost ?Im really interested in doing something like this
Pat Outdoors, what is the HP and torque of that motor you're fitting?
Nice job! Was that conversion kit specific to that bike? Are all the parts and battery water proof? Thanks for sharing.
This kit is pretty much universal from E&C. The controller and connectors are supposed to be water resistant
well done.
I've been out of a personal transportation for 2 decades. I'm very interested in purchasing your build, I would ride into Michigan winters to provide for my family?
Approx range in commute mode ie taking it mid throttle etc? Ta.
I kinda like the frame.. seems like could make it really low
What was the total time that you put into the build and the total price?
Sweet!
Good job !!!
👍😎🇫🇷🏁
I have a yz125 with motor in peices needing way too much so this video gives me great idea but im residing in Türkiye currently which electric motor is recommended.
QS138 V3 is properly geared for these dirt bikes
some 1200 grit wet sand can expedite the situation!
you can pogram the controller and take more power from it
Approx parts cost incl' the chook chaser bike?
Nice job. Hey what are those 2 little black wire leads coming from the battery?
I believe it has something to do with Bluetooth signal since there’s an app you can download to monitor the battery
@@PatOutdoors so those aren't positive leads for say running lights and other 12 volt items? I will also write the company you've pointed out in the video.
Badass!
Easy you made it look hard only because you chose to do the wires mid way I always tackle plastics and tank the harnes then the fuel lines then engine 😊
Was my first time doing something like this 🤷🏾♂️
Now only a front wheel motor and the project is complete
nice job but you could use the gas tank for more battery place , you can put easy x2 battery that you put there in the video
Thanks, you’re welcome to come by and give it a shot. The tank is not hollow and wraps around the frame right through the center of it. I’d be interested to see how it would fit
It would REALLY impress me, if you would make a DUAL Engine HYBRID bike. With an electric AND gasoline Motor.. because there is already a tank installed :)
you need thick rubber sheeting instead of foam for cushioning, the foam will wear through in minutes off-road, don't get the battery wet, don't sell the engine you might need it later,
Wish I had the funds to do this to one of mine
You did this build a few months ago.
What happened to the YAmaha TTR 90 that you Electrified???
This was just a shortened version of all 10 parts to simplify. Still working on part 3, decided to upgrade the battery to a higher spec
Hey! Nice job!
I did not find information how what range did You get from that battery pack with that controller and motor?
My calculations are that it should be about 20 minutes of fun if used on full throttle or about 70 miles cruising on flat road at speed 25-28 mph. But what are real numbers?
I’ve done about 40 minutes of wide open throttle on dirt trails. I’ve done about 1 hour of 40ish mph street cruising before noticing the power dip a lot
@@PatOutdoors
Since I am in process of making my own build from scratch(but 25kmh(16mph) cargo bike for city use) wanted to share some information. I don't know how popular is information about sodium batteries in US. Check out the Northvolt sodium-ion tecnology. Much safier and environment friendlier than lithium.
At this stage I am working with my smartInElectricityAndChemistryStuff girl to get 52v battery with that technology. She claims that theoretically these cells should be safe to charge with 36 amps. That means 20ah battery full in less than 35 min.
Those bateries are bulkier and havier at this point, but they allow deep discharge and are heat and cold resistant, and also don't catch fire if damaged. I consider that at this moment it is suitable for e-bicycles til 48v including, but not for 72v bikes(because of weight and dimensions). I understand that at this moment this tech might not be interesting for You, but keep an eye on that. It may become more efficient in close future.
@@vladislavskokosnikovs8790 well I’m also working on two cargo/long range pedal bikes for my wife and I to ride from VA to DC to MD trail systems. One is a 48V and the other is a 52V, both came stock with 20AH batteries but I’m planning on adding an additional 40AH battery on the cargo rack for both. I’m hoping I can squeeze 100 miles easy cruising range with 30a controllers
Mi potresti dare il sito dove comprare il kit di conversione
Is the old motor for sale
awesome
Ecu plug have to be face down to prevent any damp,even if it’s water proof
I think the swing arms are already powdercoated.
That electric kit is crazy expensive! It makes more sence financially to just rebuild it.
Здравствуйте,какие звезды у Вас стоят?
That is too cool, great job!!! Have you weighed the bike?
Can it go any faster? I have 2022 Lifan KPX 250 dual sport bike need to go 70 mph sometimes and would love covert to electric some day.
Yeah, just gotta play with the sprocket combo / gearing. I use mine for trail so I care more about torque and climbing power vs top speed
What happens when you're in the bush and the battery goes dead then what
Same thing that happens when you run out of gas. There’s a volt meter on the handlebar. Stars at 84 volts fully charged, turn back when it falls below 68 volts so it doesn’t shut off mid ride.
I have the same shoes 👞 🤙🏼
72V x 40AH = 2,880 watts or about 3 kWh battery. The way this bike looks like it will be run, guessing 10miles max per kWh so about 30 mile range. Cool project.
Just wanted to point out tank and especially tank wings are just air brakes, better of making something useful to fill that area.
That's about right! Thanks
It seems like you don't order the charger with the battery 🔋 kit 😅😊
Does this motor battery controller combo make enough torque to power wheelie¿
Yes, I’m just too much of a pansy and not comfortable with the rear brake
@@PatOutdoors haha, I hear ya, I'm not the best either. Just curious how the different motors do powerwise, and that's a pretty good gauge for power to size
Pat, how easy is it to wheelie the bike?
Im still learning how to wheelie so I’m not the right person to ask 😂. Pops up the front wheel way easier than my Talaria though
How much time on the trails do you figure that bike would last?
Really depends on how severe the climbs are. An earlier video I did on first time riding it on my buddy's trails lasted about 1.5 hours before it started noticeably dropping in power (but not completely out of juice.)
Could you have someone who knows how to ride Motocross test it on a track?
What sprocket do you have for j the rear wheel?
It's the factory YZ250 sprocket for the rear, 50-tooth
I’m jealous
