Thank you! I've been waiting for someone to do this. I get that there are losses but think it would be sooo much more fun to still have a manual transmission. Get the best of both worlds. Can't wait to see how it turns out!
@@bradley3549 i really don't know what to expect m8 ! my ebike though tend to have shitty efficiency when approaching its full rpms and while keeping it full throttle . i was thinking that maybe when cruising , u will be able to keep the rpms low hence having the same or slightly more range
Good on you to have the knowledge to build this.👍 I'll stick to my combustible 2/4 stroke engine. If I want to listen to a electric motor. I'll start my Singer!
@@marcthefastz1000 I actually just bought a fully loaded cat trike that came with a 49cc motor on it already - the way I see it, with the regen I can ride the battery till it's empty, run the gas motor and regen battery + solar panels, if I can get enough back in the battery there's potential for 600+ miles of travel without having to find fuel. Being able to select your own motor/battery/controller combination allows you to really tune the application. I plan to upgrade it with a belt drive and enviolo CVT hub - it works if I limit the continuous torque under 125Nm, and in a range/road specific application high torque isn't needed especially if you've got gear reduction. I want to build some hotrods but to handle the amount of instantaneous power EV can apply without shredding the drive train I'm looking at junkyards for HD belt drive trains and old shaft drive yamaha/hondas to upgrade, the powertrains are easy to find/source but getting a nice husk that doesn't have an engine already in it is the same problem I'm having launching my Kei truck EV upgrade. I'd have to buy one and sell off the power plant which usually doesn't recover the extra cost because they're *tiny* motors, subarus or not.
your buggy & any projects is interesting . good talking ... i like the way you build vehicles with good way , fabrication , precision jig , good lathe & Machinery technic , clean & so neat I'm always wait your all project , thanks ❤
I was wanting to do that with an old dirt bike years ago but then I ended up in a wheelchair. Glad to see someone doing it. Always thought it was a good idea. The electric motors and batteries are better nowadays and I think easier to find useable ones. Good job. You put a lot of trust in JB Weld.
the best thing I see with you is the fact when you get the part right or get it running or finished you start that laugh and the smile on your face shows what all diy people should have when they build something to be proud of thanks for the Chennai
I’ve been wanting to do a build like this for nearly a decade. Glad to see someone do this just to satisfy my curiosity. Looking through the comments it appears many have wanted to do this.
I kind of don't understand why you want the gearbox, I understand that the actual engine is part of the structure but the speed controller usually becomes the gears,well I know nothing about this but in say electric vehicles the speed controller is usually the reduction for lack of a better word even electric forklifts use only the differential.
The argument is presented simplicity and "no need" for a gearbox. The mechanical advantage provides the option to use a smaller motor/controller/battery and allows the electronics to operate in their most efficient range.
27:50 I recommend you to use a piece of glass if you want to sand something flat, and just glue the sandpaper with tape on the corners, because the glue interfere under the sandpaper making it not flat, on PC overclocking we use glass with sandpaper to sand our processors IHS to flat it out to get better heat dissipation so the CPU can run faster and cooler and it works really well.
a certified ground surface plate can be had for not much money if you look around.. most people don't even know what they are or care and almost give them away... gives way better results than ordinary glass although glass trick does work in a pinch ive used it myself.. glass tends to flex a bit and not get things "perfect" but close enough for most jobs it seems...
Agreed, I used the glass for lapping mating surfaces on waterjet pumps🤙 it was usually a 600 wet so I would just soak it and it stuck to the glass pretty well on its own.
I've thought about doing this for years but I was gonna run the sprocket on the outer part of the crank like where the stator goes so I could completely seal the bottom end so the crank could get oil as well. super excited to see this unfold love the crawler cant wait to see it in real action thanks for the great content Chris
Please please please make an electric mini buggy. Just grab a cheap one (I love the tomberlin crossfire 150s) and strap an electric motor and battery to it. It's a totally untapped project market that I think has big potential. Basically a mini UTV that can be had on the super cheap. A cheap, off road vehicle that can handle two adults, AND IS QUIET? That would be amazing. Gear it to 40mph, 40miles of range, with great climbing mechanics and you've got a killer machine on your hands.
I must say, this is one of my favorite projects of yours so far. Idk if it’s because of the cool factor of an ebike with gears or that it had so much cool machine work in the “crank” part. Very cool
A tip for welding on cast aloominyum cracks- grind a slot into the crack (let's be honest why else do you normally weld it) on both sides, like a beveled plate joint you'd do for some big bevel plate- assuming you learned as a boilermaker- never mind. Grind a slot in both sides to get that surface that absorbs oil cut out, and run a cold bead, then burn in slowly on the other side making sure it's a fully melted in joint (no edge lines- just puddle), using the other bead as a backer and letting the shittiness of the casting get homogenized in the excess. Then grind what you need to off with a die grinder, ideally air. I learned a lot of tricks once I stopped welding in basically a cleanroom setting..
LOL, I spent many years welding tubes, cast casing, and everything else you can find on a Boilermaker job. I learned alot of tricks working with the older guys that made me a much better welder in the long run. Dont see many mentions of Boilermakers on here and its good to read one now and then. We did quite a few tank jobs using the process you mentioned above of welding both sides. Usually we would weld one side then gouge out a nice clean seam in the backside to weld up Edit; One of the few metals I never welded on a boiler job is aluminum. Welded tons of chrome, stainless of every grade, carbon the same, some titanium and even did some brazing. But never aluminum, played with it a little on a pipe job a few times but thats about it
@@mikhail2400 haha awesome, nobody knows how to weld thick metal like a boilermaker, am I right? And yeah aluminium is weird man, like melting butter together with a blowtorch sometimes..
Would have looked good with the sprocket on the side in the cover that the electrical went in then the motor would have been more centered. Looks grate as is though. Can’t wait to see it preform.
Agree, then also by just covering the top part would make it oiltight and no welding would be needed. Also the seal plate would double as electrical motor mount.
Man your a very good Machinist Plus you can tear something like that engine and able to put it back together not knowing what your getting into !! THATS COOL OF WHAT YOU GOT DONE ! Thanks for letting me sit in your shop again and watch you
Sweeet Chris!!!!! I'm glad to see one of the big YT builders doing an electric bike! I love when people use the OG gearbox. The gear noises are just part of the awesome! Also, taking electric seriously, is very sharp on your part, bro. Electric- It's the near future.....
NOT ... AFTER THE MIDTERMS WHEN THE REPUBLICANS TAKE BACK THE HOUSE & SENATE ALL THIS EV PUSH WILL DIE OUT ... OUR ELECTRICAL GRID NEEDS UPDATED BEFORE EV'S .....
Cool build, however the facts are the electric motors in bikes are quite dangerous. I know a guy who has a kid, he got an electric dirt bike and while charging it, burned down his whole house in CA . Let's get cooking !
Electric plus gears equals awesome! Well done, I think you could have put the sprocket where the fly wheel was and blanked off where the head was would have been easier, looking forward to seeing it going will be really cool
Awesome Chris. I seen one of those Asian channels do that and that guy is brilliant. I’ve seen him take the same kind of motor you’re working on and turn them into V-Twins and in-line 4 cylinders. But I was very excited to see you do something like that. I’d love to see you convert a single cylinder engine to a multi cylinder engine too. I know you’re smart enough to do it and it would be awesome content.
Very interesting how you are designing and building this. Your machining skills totally are amazing, the shaft you designed and machined is absolutely awesome. Looking forward to the next video.
I like that you retained the clutch and gearbox. I electrified a KX 125 about 15 years ago. Direct drive. Still in use today. Registered for the street. Way more fun riding something you created yourself.
Thinking the same with counter rotating crank halves but then arrived at a one piece crank with a bearing mounted gear on the non drive side to take up any gear climb forces. Definitely worth giving a lot more thought to. I suspect you're on to the best solution possible especially if a bit of gearing is needed for the electric motor RPM. Haven't seen the specs yet. Good comment.
I know you like to try different things, but I'm wondering about the additional width and additional weight how this will really handle in the dirt. And with a gear box there will be additional friction which the battery will have to power, so you'll probably need a bigger battery than you would without the gear box. It will be interesting to see the conclusion of this project.
it's really insignificant. You have advantages using the clutch and gearbox just as the ALTA Redshift did. As someone who has done the same thing with a CR 125 dirtbike direct drive to the rear sprocket and changed to using the 125 gearboxes. It's much better with the gearbox. Especially with an inrunner-type high RPM motor. Direct to the rear sprocket with a chain lacked torque. You would need a hub motor converted to accept a pinion gear. In the end, the weight is still the same. The inrunners just like Chris is using don't have much torque like outrunners. A gearbox or a major reduction is a must.
@@FarmerFpv yep its far easier for a small motor to trade high RPM for torque then tor try and make a motor deliver that torque directly. also motors that can deliver that much torque directly draw fairly high currents that means bigger inverter and more cooling.
@@phalanx3803 From what I am seeing, most bldc motors only run 5-6k rpm. The build I am planning is a 96v 250amp (higher volts = lower current) and trading some of the excessive torque for hp. Hopefully making it actually highway worthy.
JB weld will hold for a bit but the proper way to fix a crack is to drill a small hole at each end of the crack to stop it from spreading then grind it to Grove the crack and weld from both sides basically replacing the fractured metal with new. But if your going to JB weld it at least drill the ends so it doesn't spread
Steel stick would have been better for the crack. I've seen him use it before and was surprised he didn't use it this time. Oh well. That epoxy resin sucks!
Couldn't you just hook up the sprocket to the flywheel side? That way there's already a seal, you would only need to machine a tapered sprocket to fit where the flyweel was. You don't even need to machine a new crankshaft, but doing it and getting rid of the counterweights is definitely better
I know you’re duplicating another build, and it’s too late to change it now, but I think it would be really cool if the motor had mounted where the old cylinder was and drove the crank via some bevel-gears. It would have a footprint and planform much closer to the original engine, probably get a couple double-takes from people not realizing it’s electric.
Great I love the idea... But I would suggest a fine brus to close up te gap on the plate to keep dust from going in to the casing... Aswell as keeping the chain clean
I bet you think pissing on the seat and leaving it’s OK too? It’s lazy and ignorant that’s his house his property If you drained gas on my shop floor or ground I’d ask you what are you ignorant I don’t spit on your floors Or piss on your toilet seat and then tell you clean that shit up!
@@donanders2110one gallon of gas is enough to ruin 1,000,000 gallons of water in Florida, Rickard Kopf. It’s also a crime in many places and I don’t think you know what you’re doing. Far worse is trying to use a loose spline . 😊 God bless your heart ❤️
I just finished doing a full case split rebuild on my 85 ACT250R and I ended up putting my parts in a toaster oven to off gas the cases, cylinder, and head before painting. It worked great. 500°F for 15 minutes each.
I think you should Box the chain in with something easily removable it will it would cut down on some of the chain noises as well as keep the dirt out.
You are one ambitious dude, congratulations, got me thinking instead of a piston how about modifying some large solenoids to push and maybe even pull the connecting rod up and down. Then custom electronics to shape the waveforms could make up for many, if not most of the losses of reciprocation. Maybe someone will see this and take it further. I currently lost my workshop or should I say I'm between work shops.
DUDE! That crank replacement was a work of art, you should be proud of it. And I totally agree, even though gears aren't really needed for electric motors, having gears makes them a million times more interesting. I only hope electric cars will have them someday.
Cool. Maybe you can put one more motor on the other side of the sprocket. And make it a twin. And a nice cover over the chain will make it more silent. This will be really good.
As I am a 30 year machinist and I seen the video a while ago ,I am truly impressed w your mechanical prowess u prob have a very hi iq good job on your successful endeavors, very impressive, especially since you are a one horse show.
34:28 Is it me or did the motor have quite a bit of play during the testing portion? I assume you'll brace it more after the install, just want to make sure it was didn't go under the radar.
I've got a 4kw motor and I had a similar thickness motor mount. This definitely will need extra bracing. My motor mount ended up bending from the insane torque
Great job re-engineering conversation gas to electric maintaining the gear box portion. Great concept and machine work. Looking forward to seeing it run.
Im.with you on chain cover. Let's not over complicate the seal though. Piece of fuel line for weedwacker split with razor will slip over edge of guard and seal great. I've done with in a pinch when didn't have grommet for hole in metal to run wires through. Love ur hard work for sure
For a good base for trueing surfaces with Emory cloth I use half inch plate glass. That works great, very flat. I use it to true up hand planes. Love this build.
Hi Chris I used a 110 cc motor like that and converted it to a gear box but I had a car alternator on it but then I was thinking about doing it to a 125 cc 2stroke with a clutch but I never got there that one . allsome work 🌟 you really took that one to the next level so cool allsome stuff from cruzermans inventions 😁🎉👌

just a suggestion, you no longer need the gas tank, gut it out , make the outer shell a battery cover.
Exactly. Have done this a few times. Works great. Just make sure you get some air flow through there to cool the battery and speed controller.

Probably shouldn't video record gas dripping on the ground...
Wow just love how you see something in your head and machine it out !!!! Amazing !!!!

So about 6kw x 746 = 8 hp. Plus you have the benefit of gears and instant torque of electric power. Should go pretty good 👍🏻

6kw is also the rated output. Depending on how the controller works, peak output could be much higher. Should be a little ripper

why didnt you just move the motor left 3 inches and have the chain stay outside the block?
This is what I'm wondering. It would center the motor, and you could just cap off the crank case and be done with it.
One of my favourite channels sir! you always inspire me to get back out into the shed and keep tinkering 👍
One upgrade would be top use pinion gears - more work, but you could mount the motor vertical in line like the former top cases.
Thinking the same with counter rotating crank halves but then arrived at a one piece crank with a bearing mounted gear on the non drive side to take up any gear climb forces. Definitely worth giving a lot more thought to. I suspect you're on to the best solution possible especially if a bit of gearing is needed for the electric motor RPM. Haven't seen the specs yet.

Especially with an inrunner-type high RPM motor. Direct to the rear sprocket with a chain lacked torque. You would need a hub motor converted to accept a pinion gear. In the end, the weight is still the same. The inrunners just like Chris is using don't have much torque like outrunners. A gearbox or a major reduction is a must.
@@FarmerFpv yep its far easier for a small motor to trade high RPM for torque then tor try and make a motor deliver that torque directly. also motors that can deliver that much torque directly draw fairly high currents that means bigger inverter and more cooling.
@@phalanx3803 From what I am seeing, most bldc motors only run 5-6k rpm. The build I am planning is a 96v 250amp (higher volts = lower current) and trading some of the excessive torque for hp. Hopefully making it actually highway worthy.
awesome, I enjoy watching you coming up with ideas and then machining them on video. I really enjoy watching the machining.
JB weld will hold for a bit but the proper way to fix a crack is to drill a small hole at each end of the crack to stop it from spreading then grind it to Grove the crack and weld from both sides basically replacing the fractured metal with new. But if your going to JB weld it at least drill the ends so it doesn't spread
Steel stick would have been better for the crack. I've seen him use it before and was surprised he didn't use it this time. Oh well. That epoxy resin sucks!
Always Dreamt of some electric dirtbike like that😂😂
Couldn't you just hook up the sprocket to the flywheel side? That way there's already a seal, you would only need to machine a tapered sprocket to fit where the flyweel was. You don't even need to machine a new crankshaft, but doing it and getting rid of the counterweights is definitely better
I thought the same thing.
That 6 jaw chuck is sweet. This conversion is really cool too
I know you’re duplicating another build, and it’s too late to change it now, but I think it would be really cool if the motor had mounted where the old cylinder was and drove the crank via some bevel-gears. It would have a footprint and planform much closer to the original engine, probably get a couple double-takes from people not realizing it’s electric.
This dude is good👍 Just decides and works through whatever problem keeping him from reaching his goal. Sweet!
You shouldn't drain gas into the ground
Great I love the idea... But I would suggest a fine brus to close up te gap on the plate to keep dust from going in to the casing... Aswell as keeping the chain clean
Dude there’s no acceptable reason why you just let that gasoline run out on to the ground !!! 💩🤯🤬
that little bit of gas will evaporate, lighten up Francis!
I bet you think pissing on the seat and leaving it’s OK too? It’s lazy and ignorant that’s his house his property If you drained gas on my shop floor or ground I’d ask you what are you ignorant I don’t spit on your floors Or piss on your toilet seat and then tell you clean that shit up!
@@donanders2110one gallon of gas is enough to ruin 1,000,000 gallons of water in Florida, Rickard Kopf. It’s also a crime in many places and I don’t think you know what you’re doing. Far worse is trying to use a loose spline . 😊 God bless your heart ❤️
I just finished doing a full case split rebuild on my 85 ACT250R and I ended up putting my parts in a toaster oven to off gas the cases, cylinder, and head before painting. It worked great. 500°F for 15 minutes each.
I think you should Box the chain in with something easily removable it will it would cut down on some of the chain noises as well as keep the dirt out.
Best back yard mechanic (Engineer) ever. Period(.)
You are one ambitious dude, congratulations, got me thinking instead of a piston how about modifying some large solenoids to push and maybe even pull the connecting rod up and down. Then custom electronics to shape the waveforms could make up for many, if not most of the losses of reciprocation. Maybe someone will see this and take it further. I currently lost my workshop or should I say I'm between work shops.
After suggesting it numerous times, finally an electric build. 👌
DUDE! That crank replacement was a work of art, you should be proud of it. And I totally agree, even though gears aren't really needed for electric motors, having gears makes them a million times more interesting. I only hope electric cars will have them someday.
Cool. Maybe you can put one more motor on the other side of the sprocket. And make it a twin. And a nice cover over the chain will make it more silent. This will be really good.
Man that is really cool! You could call it the “Stealth-cycle”. The bike you can ride by your neighbors and stealthy give them the bird.
As I am a 30 year machinist and I seen the video a while ago ,I am truly impressed w your mechanical prowess u prob have a very hi iq good job on your successful endeavors, very impressive, especially since you are a one horse show.
34:28 Is it me or did the motor have quite a bit of play during the testing portion? I assume you'll brace it more after the install, just want to make sure it was didn't go under the radar.
I've got a 4kw motor and I had a similar thickness motor mount. This definitely will need extra bracing. My motor mount ended up bending from the insane torque
Amazing job! some excellent metal working here
I did that 30 years ago with the Toyota Celica me and my buddy.👍👍
Great job re-engineering conversation gas to electric maintaining the gear box portion. Great concept and machine work. Looking forward to seeing it run.
Im.with you on chain cover. Let's not over complicate the seal though. Piece of fuel line for weedwacker split with razor will slip over edge of guard and seal great. I've done with in a pinch when didn't have grommet for hole in metal to run wires through. Love ur hard work for sure
For a good base for trueing surfaces with Emory cloth I use half inch plate glass. That works great, very flat. I use it to true up hand planes. Love this build.
That time lapse beat is super groovy😎
Banging through gears is the best part about a dirtbike!
this level of craftsmanship is epic
I have thought of that before and thought I could do it myself someday but you beat me to it.
Hi Chris I used a 110 cc motor like that and converted it to a gear box but I had a car alternator on it but then I was thinking about doing it to a 125 cc 2stroke with a clutch but I never got there that one . allsome work 🌟 you really took that one to the next level so cool allsome stuff from cruzermans inventions 😁🎉👌
Can't wait till its complete I have 3 of these love to make them electric.. great work
Great watching one-off bits being machined ! 🤓
Love your fabrication skills don't get me wrong but I would have started with a 2stroke lower end
🤝
💐The electronic engine you have made is a very powerful engine, I am impressed by it, for the first time in my life I have seen a person who can speak so clearly, I am very thankful to you, because you have given me your brilliant idea. show me...♥️♥️👍👍👍🤝🤝🤝
After a while don't watching your videos im impressed with your Workshop goin from a div lathe to a (looks like) really nice one and welding aluminum with Tig is a really impressing
did this when i was 14 with an old kx80 bottom end and 9hp generator motr. lol. goes so good. can only imagine electric tq through it
You have some serious machinery there, impressive.
Can’t wait to watch part 2 and hey you should sell a kit like this I know people would buy it
Well that shot your badassery up by at least 2 levels Chris. I mean the numbers are not officially crunched yet but... At least 2 levels. 💯♨
Changing up the game sweeeet can't wait to see it finished 🙌
i think youre the best fabricator on youtube
That feeling of accomplishment 😁 when you know it was all your own doing , well done brother from the other side of the pond Scotland 🏴
