stopped everything i was doing to watch this, the only thing i've been looking forward to on youtube.

Being a motorcyclist for the past 50 years, when I saw what you were building, I thought so much un-sprung weight, so many issues to make that work. But you you did it. Congratulations, Well Done! Keep up the amazing Fab work.

People that can engineer then build something this rare… nothing but my utmost respect and admiration.

Suggestion for you on prepping future tires. Why not build a jig that holds a seven-inch grinder with a flapper disk, and glides in the preferred arc shape of the tire? Have the tire rotating at constant speed, while the grinder reciprocates back and forth on the arc rails (think like a roller-coaster track in a semi-circle the radius of the preferred tire curve). Build the whole arc/grinder setup on a vertical, variable-height, track setup (could use a trailer crank jack to adjust the height until the edges of the tire are at preferred radius). How it would operate: 1) Mount the new tire in the jig and get it up to a slow, constant rotation. 2) Turn on grinder/arc device, which continues to sweep back and forth along the arc track. 3) Use the trailer jack to lower the grinder/arc device a sixteenth (or so) of an inch every time the tire comes out of contact with it. End result should be a nearly uniformly worn, curved tire face. I'm only suggesting such a tire jig be made if you plan on needing to make several more tires for various projects (and, a bonus, you could be doing other things while the jig is in operation, only needing to readjust the cut height periodically throughout the process). Just my humble thoughts.

Was it worth the wait?

Now build a mirror image chopper, and you can combine them into a 4 wheel terror that splits back into two when the trails get narrow. Then recombine it again.

I am sure Hollywood will be calling and want that in a super hero movie. Great build!

at 24 minutes plus, add "chain tensioner"! This is such a fun project to watch, and it's performance assures me that mankind can occasionally exceed expectations!

There's got to be a tremendous sense of pride building something so unique. Truly a one-off. So impressive.

Looks like something Batman would ride

Very impressive thank you for all the hard work you guys put into it. Enjoyed watching it grow from the beginning.

Watching ur series on this has been inspiring to say the least my man. Enough to make me go back and finish my degree after 15 years so I can better tinker about more with the things I love. Keep it up man!

The day we have all been waiting for!

When you said 863 lbs. I almost fell out of my chair. Cuz that is exactly what my 1983 Kawasaki 1300 6 cyl. Voyager Weighed. Smoothest bike down the road I ever threw a leg over. The thing even had an onboard air compressor to adjust ride quality and height. When you get ready to ride that thing out on the road you need to get a black helmet with little ears and a black cape. IM BATMAN! Nice work Ethan

I think everyone has thought about making something like this, but no one has actually done it. Well done.

The first episode of this thing becoming an idea to build is the reason I subbed. So sick

I'm a welder/fabricator and I absolutely love the work done on this! It's some excellent engineering.

You guys are probably one of the only channels I watch where I can sit through a video thats half an hour or longer and want more instead of clicking off after 10 minutes and builds like this is exactly why. just insanely cool builds that are like a dream scenario come true

This beauty is why I started watching Grind Hard. It's beautiful to see her up and running!

Well done @GrindHardPlumbingCo I was following you from the beginning of this build and I enjoyed seeing all the team that appeared in camera and off camera, I love the close-ups in slowmo. Thumbs up to all the team ...including the furries. 👍 Looking forward to seeing more crazy builds!

First video on this series was over 7 months ago! This was a WILD amount of work! Can not wait to take it on the streets...

You need a cush drive. A damper, normally rubber between the sprocket and the wheel. It will absorb a lot of the shock that is recking the chain, sprocket and probably gearbox. .👍

congrats! it's been a great ride along with this project! thanks!

I do believe this is the coolest KZfaq vehicle build ever. I was skeptical when it fell over with the square tires but this came out incredible.

As an autozone worker, those duralast jump boxes have gotten me and my buddies out of a LOT of sticky situations. Thank you for buying our products ethan! :)

The wait was so worth it! The monster chopper does indeed rip, and so much better than I expected. Once you get the chain tensioner, maybe improve the brakes, and get this thing fully cleaned up and painted it is going to be a thing of beauty. A murdered out all black look and this thing would become the bat bike.

My brothers and I have built some wild things in our time, but nothing we ever built can hold a candle to that bike. Great job, love it!!

Freaking amazing work!! That looks sooooo fun to ride!! Can't wait to see you when it's all painted up and pretty... Phenomenal work keep it up!!

I have been thinking for months that this thing was going to just instantly kill someone. So awesome to see it rip! Such an iconic piece of art. Congrats!

I really enjoys the long un-cut shots like the one from 8:30 to 10:30! Thats two whole minutes without a single cut. Makes it feel so authentic and makes it more engaging

Love it when people take the time to do something "right" no matter how much extra time it may take.

Many cudo’s to you guys, for making something absolutely insane that actually works. Deep bow

Grind Hard is the only channel I have notifications on for lol

24:29 Right after Ethan points out it could use a chain guide because of the bouncing you show a clip where that is clearly visible. If that is done with intent you deserve praise dude, nicely done. I've been kind of skeptical of the rideability of the bike since the start but knew I would probably be proven wrong, and imd glad I was. This bike is going to be legendary.

This thing had so much work go in to it. It makes me so happy seeing it ride as beautifully as it does!

Totally worth the 2 month long wait to see it rip. Anyone else liking that Ethan’s long term projects are a series while the swindler brothers keep the channel juiced with classic grind-hard entertainment?

Dude...!!!That's straight from Mad Max,insanely AWESOME!!! Do you guys realize how blessed you are for real...?

Of all off the creations that I've seen you guys build throughout the years that I've followed you, this is the one that has utterly blown my mind 👌🏻

This was definitely worth the wait and definitely worth all your work looks super wild in the clips of you just riding by

What a monster! As a hobby welder I love seeing all the custom metalwork in your vids. Seems like you could really send it if you build some crashbars around your legs kind of like the front part that sticks out. That way you can take turns without fear of it tearing your legs off when it inevitably tips. Also might be worth adding a second beefy shock on the rear to keep it planted back there and prevent all that unsprung weight bounce. Can't wait to see what else you guys do to it and how it rides once you get it dialed and get used to it. I'm sure there's a hard learning curve since this has never really been done before

Ethans knowledge, experience, and imagination really shined through with this project and seeing pride from all the effort and planning was so cool. Awesome stuff.

The way Ethan can come up with a fix out of thin air is crazy. “He’s a wizard Harry”. 🤣

Ive been looking forward to this video! Cant wait to see it with some paint.

All that comes to mind is Mad Max. Amazing what some creativity and a lot of elbow grease can accomplish. Congrats

My husband I have been watching this build since day one. Worth the wait! Also loved Bjorn arguing, This bike gives post apocalyptic cruising through the dystopian wastelands for supplies vibes! Love it! Hard work, imagination and the engineering very impressive.

CONGRATS GUYS ! been following that build, glad to see it come to life cant wait to see you ride it hard

Yeah, been following this for a while. Had my doubts at first, but holy shit! Good job guys!

Yea man !! Good job and it was worth the wait!!!!! .Real 😮 cool you put some hard work into this monster bike and its awesome. I'd buy one! SENDIT!!!!!!

This might be the most satisfying build y’all have ever done. It rides so much better than I dared to hope. Incredible labour of love. Nice work to the whole crew

Can’t tell if this belongs in Mad Max or Mario Kart…

Congratulations!🍾 finally! It’s alive!

BEST Thing I've Seen in 2024 .... Keep Being Creative n Innovative....👊🏼 And I See Both of the One Sided Swing Arms ..🔥

Batman won’t be happy about this

Man, seeing Ethan get more and more confident in the bike and just giving it the beans is a pretty spectacular sight. This is way freaking cool!

newer seen using hand tool to adjust wheels, we usually use a lathe for custom of rubber surface, to ensure its 100% smooth/symetrical

I never paused from watching !! Very Creative and Exciting Project 😊

EPIC build! This has been so cool to watch, all of the custom fabrication work has been crazy. From the moment you pulled it out of the garage in this video I was thinking "we NEED to see this thing on the dunes"... and then Ethan said he was thinking the same thing. Do it!!!

Has a brand new clean shop 20 ft away still uses a rock to measure out a chain. This is why we love ghpc!

In Southeast Asia and India they have these two-wheeled "walk behind tractors" that all use the same low-horsepower single-cylinder diesel engine. Pungidda-pungidda-pungidda, forever and ever. Perfect for this beastie. I'd ride it every day.

I had my doubts at the beginning. Well done.

This was incredible! We have been waiting for this day since you first had the engine sitting on blocks between the tires! Nice work! Can't wait to see the next steps

Immediately watching after getting home from work, I have been looking forward to this video like crazy! Extremely cool to see the progression on this, everything you’ve done to fine tune it to get to where you have it. It really has been such a pleasure and good time watching! Killer job as always, you guys always go all out in your builds and don’t really cut many corners, making for an extremely unique and quality built custom piece of machinery!

Been waiting to see this one. Congrats guys

Jeez, finally got to see this monster in action! 👍🏼👍🏼👍🏼

7 months has come to this awesome machine. Congrats on the build!

Ive been so excited to see how this project comes along. Great work guys!

Oh thank goodness and congratulations on validating your madness.

Ok I’ve been waiting for the Akira bike since I saw you building it it looks amazing

I've been watching you guys from the beginning and now the level just went through the roof, amazing work grindhard ✨

Love it, well worth the wait. Congrats on creating an absolute bonkers build. Looking forward to the continuation of working out the bugs. Excited to see what you cook up for the chain tensioner/guide gizmo.

I was watching another channel and this came up after, and I was hooked. Awesome bike and I'll be checking out some of the other videos on your channel. 😊

Nice to see it finally get test driven....looks awesome!Now just some paint.

I'm so glad this monster is finally running. I really can't wait to see this build finished

Wow! Honestly, I didn't expect it to work so well. Great and impressive job! 👍

Beautiful build. Ride it around the world and post videos.

Beautiful craftsmanship & I bet there will be many adventures with it ahead. 👍👍

Finally. Been waiting to see this beast move more than a fence post. Heck yeah man. Good job guys.

Congratulations!! I had my doubts, but never again. Incredible bike!

Awesome work guys! It actually became rideable!

never thought you be able to rip around on it. remarkable engineering job

Best notification you could ever get 👌Watched the entire build process from day one and it's unbelievable. Well done and congrats guys

Been watching since the first video of this build. Love it great job!

I know this comments a little late but wetting the blade helps cut the rubber quicker, use plenty water, keeps the rubber cool and the blade slippy 👍🏻👍🏻

Thank you for including the time stamps on your video

Massive congrats on the epic monster bike, look forward to the upgrade and blat round tour.

You know it's a great day when you finish watching cleeter and then this pops up! Pumped for this one!!

I've also been excited to see it done

Nice build guys. You're fortunate to have all those handy tools to machine nearly everything you desire. Always dreamed of having a shop like this. The drone coverage is top choice!! The bike flipping upside down is concerning for your safety bro. With the front arm being out to the side, chain, sprocket, etc, I wonder if it's left-side heavy. Maybe rounding off the tires lost some of that stability with turning, but it's just a guess. The Mitsubishi, looking like a Suzuki Multicab here in the Philippines, with 6 wheels, is awesome! Guys here run the 4x4 660cc 3 bangers through the woods and get stuck. Yours is pretty trick with the intermediate wheels. Love it. Nice channel guys and cool monster chopper!

This is the most impressive and surprisingly functional mutant machine I have seen your crew build yet! This thing is unbelievably cool and deserves to be in a movie!

Outstanding and awesome as always.Thanks for sharing and taking us along

Can't believe this worked out in the end. It's so cool. I wonder if 2-wheel steering would make it more rideable, with gear reduction steering so a twitch of the handlebars wouldn't make it lose control. Obvs a drivechain would make that difficult so if there was an in-hub electric motor at one or both ends that would work I think...

Love it. Been waiting forever

im really happy that it work and i hope it will continue to be as good 🎉 good job guys!

Im at the ranch building a shed with my unkle and had to take a break. This is a perfectly timed upload. Keep up all the awesome building projects 💯❤️🙏

Very nice, what an impressive build! 🎉

The coolest thing I've seen all week :)

This is a perfect example of underrated channel on KZfaq

13:30 Maneuverability can be improved by tilting the steering axis back 20-30 deg toward the rear. Right now, the rider leaning is doing a lot of work to turn the bike, but that can be made easier. Tilting would also improve low speed turning dramatically, likely preventing tipping over. Check out other bikes front steering axis to see what I mean. I'm a Mechanical Engineer.

That's a definite win for the first couple of drives! Really quite impressive how well that worked for a complete custom build.

It's really great to see true artists doing their work in a remote shed somewhere this way. I bet it's pretty stable due to that center of sprung mass being around wheel hub height. And the wheels are probably a third of that weight.
