We are on CZcams trending! #21 Please Share this video with a friend and let's see if we can brake the top 10!
The shocks aren't 'soft', the angle of incident is excessive.
At 20deg, the downward force is multiplied by three
At 15deg, the downward force is multiplied by four
At 1deg, it's approaching infinity. Seriously, take a class in trigonometry.

Didn't this channel have another guy? Hope he is ok
Another saying is it only hurts wile the pain is there
Who else here saw the short and came to see him test ride this beast?
Extremely disappointed
this was top comment and got my hopes up he didn’t test drive it 😢😂
So is it just for looks?
@@skubasteveskilla3316 if your new to the channel asking this, I wanted to answer based off of being a fan for a few years and ethan will definitely finish the motorcycle
Been following these guys before they went viral pimp.
I think it looks great, I would even think 2 springs front/rear might be better. I would put a high back seat bar on it though I can't imagine the injury if you fall backward and that tire tries to eat you.
I kept seeing them bounce on it and that’s all I could see, massive grippy pinch point that will suck you between frame and tire and be like a human chipper. 😳
@@robertwilk-WabbieWasabi666they could call it the Human Chopper 😂
@@whatseedee9744 nah, that’s uh, something else. 😶 The Monster Bike works two different ways, big like a monster truck, and eats people like monsters do. 😂
The problem with suspension is that if you for example have 3:1 leverageratio in linkage/ swing arm, then the actual spring rate at tyre/ wheel axle is spring rate divided with 3^2=9 -> spring/9. Or if leverage ratio is 2:1, then actual spring rate is spring/2^2= spring/4. That is one thing what most of the people, if "any", knows. And that is why typically these trial and error fabricators end up doing way too soft suspension.
(Typically 600/100 street bikes have 2:1 linkage ratio, so when you use those shocks, keep that in mind).
And also, if you want to use stiff spring, and you want to suspension to feel soft, then you just have to revalve compression damping and decrease compression damping, and suspension will feel soft even if you have (very) stiff spring.
@@deadslow201 this comment is more about the tire than the suspension, there’s not really any safeguard keeping the rider from falling between frame/tire and becoming paste. That knobby tire gets you at any speed at all and it is all over. They need a backrest or a fender there.
After a lifetime (75 years old ) of construction work of all types…these videos make me feel so inadequate….Love them!
That tube work is absolutely amazing and watching how you test fit and designed it all was really cool to see. I’m a boat guy and not really into this type of stuff personally but it is so cool to watch. It’s unreal to me the amount of engineering it takes to put this together. The footage and B rolls in your videos are great also!
Ethan! I enjoy fabrication myself. Built my own race truck. One suggestion I haven't seen mentioned, perhaps get a tire tread cutter and "shoulder" the edges of the tires for a rounder profile. It'll help immensely with leaning and turning!!! Love the videos! Been watching since the beginning.
I was thinking the same thing. Having such a squared off profile on the front tire and how a bike (actually turns opposite from the direction of handlebars) leans will be something to address. But boy what an EPIC build!!! Ethan your not alone in the OCD with overkill and details!
For sure! That thing will be friendly without those paddles on the sides of the tires
Over inflate.
When you have the engine running, put the rear of the bike on a stand, and cut/ shave off the square edges of the tyres/ make the tyre profile much more round. It will significantly improve overall handling of the bike.
Honestly, I believe everyone is overthinking this. This is not going to ride anything like a traditional motorcycle. I would imagine the majority of its life will not be on pavement. So are the shape of the side lugs really gonna make that much of a difference ? Ever ride a bike with a 300 rear tire ? They have a rounded profile and handle like absolute garbage.
So long time fan. And idk if it’s coincidence or not but, I enjoy you guys using Edwin and Wills content as like an ADHD fluff while letting Ethan take his time and actually build something serious. Been an awesome few weeks of content with this format. Been enjoying it a lot.
I disagree wholeheartedly. Make another channel for that garbage. I finally had enough and turned the last episode off after 4 minutes. I have a 1 "shreked" limit now. I will not watch will builds. I lose IQ points watching those guys .
haha thats a good way to put it. agree
like santa and his elves (who are also the production crew)
@@jasonbirch1182relax dude, just skip their content lmao
@@jasonbirch1182 bro do you need a hug? That’s pretty shrecked you feel like that. Touching some grass would be premium for you
A lot of fun watching an artist at work - your creative process, the small decisions and attention to detail are what makes your builds so special imho
This build is so epic. The body lines, vision, every little detail is awesome. Cannot wait just to see it moving
As a machinist, I would recommend to try using ceramic inserts when cutting hardened steel. Higher spindle speed as well.
i was going to suggest not using cheap chinese inserts, a quality brand would make it easier. people buy these small tool kits off ebay and expect them to cut like a set of iscars
He could also buy a proper tap guide for the lathe instead of using the live center lol
I think you guys are starting to put the cart before the horse. I don't think that little lathe has the ponies to be able to get the spindle speed that you want with any kind of power at all.
As a machinist, my tenticles creep up into my abdomin just watching this.
@@ihdieselman how so? noone suggested bigger cuts, just using the correct tools. harder material means more deflection especially with small boring bars. higher spindle speeds doesnt require more ponies, just more gearing.
This channel consistently has some of the coolest and most imaginative projects. Watching the fabrication and attention to detail reminds me of watching American Chopper back in the day or Monster Garage minus the overproduced reality tv drama layer those those types of shows tend to have, which was always my biggest gripe with them
Yeah, it’s funny how the fake reality is the worst part of “reality” shows
@@GrindHardPlumbingCo If you don't finish this bike by the weekend you're gonna lose the shop! Which would be a shame because you only just got it.
As I read, "reminds me of watching American Chopper back in the day," I thought to myself, "minus the overproduced reality tv drama layer those those types of shows tend to have, which was always my biggest gripe with them." Then I read the rest of your comment. Lol.
Stumbled across this while recovering from illness in the UK. I ride motorcycles but this blew me away. Awesome guys!!
This might be my favourite build on your channel and in the top 5 of my favourite CZcams builds!
Such a unique design and clearly no one else is really building anything wild like this, love the channel!
A thing I noticed is that the front suspension has a very very large degree of geometry change through the suspension stroke do to it using a knuckle design combined with a single pivot swingarm. If you look at the Bimota/Vyrus system, they also use a single pivot, but the axle is floating with a rod leading back to the frame so that the steering angle of the hub remains the same as swingarm angle changes. Other systems like the ELF Honda use a knuckle kind of like yours/a car, but are a true parallelogram setup (like a double A arm car) so the steering angle is also fixed.
This is the third american? front swingarm bike I've seen. All 3 of them have totally ignored this.
I've built a few funny front ends on motorcycles. What Ethan is making will be just fine. "Good enough" front steering geometry is very forgiving. (while "perfect" geometry is super picky)
The high pivot point for the front swing arm annoys me more. It will make the suspension Harsh on bumps taller than about 12"...
Yes he will have caster change as the suspension travels. Not sure if that's an issue on bikes but some older cars like 1st gen broncos have a huge caster change as the suspension travels and it's a non issue. Come to think of it a Ford twin I beam has caster change too
Dude this has got to be the craziest thing ive ever seen anyone build. When is Ethan going to start teaching a masterclass on fab work?! Insanely cool to watch this project come together! Nice work fellas
This is SEMA worthy. It's better than anything that came out of OCC back in the day...except maybe the Black Widow lol.
fab work I 100% agree, design work is not that high
Your 'weight savings' on the knuckle and the bike frame look crazy good. I've thought that about every build where you do extensive frame work and fab work. It's intricate and light and really - just truly- a work of art, every single piece
I'm living for this project. It is coming together nicely and I can't wait for it to start driving on the road!
I have to admit I was skeptical when this bike was being described before the build started but seeing it come together, it is so damn cool looking. Best form of working art I've seen in memory.
Right!? As a biker, I was like "They've built some crazy stuff before, but this sounds like a death trap. I'm not so sure about the safety of this." I really hope that he puts something between his ass and that tire. And that's just my first concern. But now I'm a little less concerned than I was a few weeks ago. 😂
Looks sick so far!!! just FYI, the reason the suspension is a bit soft is because of the massive leverage that the front and rear swingarms have. In a normal motorcycle, they are more like 1.5-2ft long, and this is like 3-4ft. Longer levers mean more leverage on the springs.
The problem with suspension is that if you for example have 3:1 leverageratio in linkage/ swing arm, then the actual spring rate at tyre/ wheel axle is spring rate divided with 3^2=9 -> spring/9. Or if leverage ratio is 2:1, then actual spring rate is spring/2^2= spring/4. That is one thing what most of the people, if "any", knows. And that is why typically these trial and error fabricators end up doing way too soft suspension.
(Typically 600/100 street bikes have 2:1 linkage ratio, so when you use those shocks, keep that in mind, and spring rate is 100Nm:ish.)
And also, if you want to use stiff spring, and you want to suspension to feel soft, then you just have to revalve compression damping and decrease compression damping, and suspension will feel soft even if you have (very) stiff spring.
Explain like I'm five please....@@deadslow201
I worked in the Marine Propulsion industry for a few years as a mechanical designer. We used to have bearing surfaces fabricated in to our input pinion shafts for the bow thrusters we manufactured from scratch. After initial machining of the pinions shafts from bar stock, post-spline work, etc. was done we'd ship the shaft off to have the bearing seat chrome plated, then grind the chromed bearing seat to .0005" press fit. Worked really well.
This is far more entertaining than any network shows I've seen. Well done! Amazing how low you got the center of gravity. She should corner like a bobsled.
What I love about this channel is your attention to detail and how you try to not half ass any of your builds.
Not even joking, I had a dream about seeing this masterpiece move under its own power. I think its safe to say, this has been my favorite build to date. I CANNOT WAIT TO SEE IT FINISHED. i hope to see videos of you guys using it well after its finished. I dont ever want to see it go!
Oh, we are going to use the crap out of it don’t you worry!
The mechanically ridiculous done with great passion enthusiasm and skill. You guys are such a PREMIUM channel. I can’t wait to see this bike roll.
Not sure how I stumbled on this channel - but I'm glad I did. Truly a master and artist at work! Tube assemblies are one thing I never really learned, but you make me want to!
I know everyone is always talking about the builds and those are, without fail, mindblowing. But can we all just take a minute to appreciate the videograpy. Stunnyly lit scenes, jaw dropping pano's, presentation scene comps that rival fashion magazine cover shots, and who ever flying that drone indoors has the hands of a surgeon (almost lol). You guys floor me with every video and I hope you keep making top tier content for many years. Y'all just became the first channel I choose to DIRECTLY support
Thanks man! Your comment made my morning!- Edwin (the drone guy)
Also every piece of music matches the scene perfectly & absolutely slaps! Put them all in a playlist & they are mostly different genres aswell that wouldn’t usually go together in one video which speaks a lot to how well it’s done. Do you make ALL the music Edwin or just a few? Love your work
@@GrindHardPlumbingCo Greetings from Ukraine guys ! Awesome content !
Actually, I was starting to feel like all the tricky camera angles and fancy editing was starting to detract from the quality of the video rather than allowing me to enjoy it. That stuff is better when it's not as noticeable.
@trasberg 💯 don't share that opinion. How does production value detract from video quality? Whatever your answer is try getting ANY industry professional to agree.
I was literally just finishing the go cart video when I got the notification for this video
I was watching the 6 wheel conversion of the kei truck l😅l
It's the attention to detail that unreal. You take an amazing piece you built, look at it, think nope I can do better. Love the work you guys do. Been watching for years, by far my favorite CZcams channel
Dude, iv only just started watching you lot, and iv followed this build.
Your work and engineering skills are making a peace of art pal.
Thanks for sharing 🎉❤
This is so sick man. One thing I’m concerned about is if you slide into the back tire and get sucked down behind the seat.. that could be bad
that was the first thing I thought about too!. hopefully they put a fender over it.
Nasty way to go.
The rotating shot at 15 minutes is really cool. Been loving this build!
I hope you realize that with that massive front wheel spinning at speed, because of gyroscopic forces, it will take a lot of power assisted turning to get both wheels to break from parallel. That's the problem most people have with this style bike build that I've seen. That's why people are telling you you wont be able to lean (while going fast). The amount of force it will take to counterturn the front wheel to lean into the turn, then turn the wheel the opposite way into the turn will be crazy. The other builders I've seen didn't figure it out, but now im telling you, so hopefully, you can tackle it since this is one of the coolest bikes I've seen. Good luck.
I was skeptical that this thing would be ridable but after seeing how easily Ethan leaned it and balanced it; it's totally ridable.
The wheels weren't spinning the centripetal force will be massive.
True but i doubt this thing will go very fast, it would be certain death at anything over 40@taylorsukoshi6126
That bike is going be an animal when it’s done I’m so excited to see the finished product, great job gentlemen…..👍🏻👍🏻🫵
Maybe I've missed it being talked about, but how hard will it be to see around the massive front tire? I think this will have extremely low center of gravity, relative to the axles, so I'm very interested in how that and tire size affects the suspension characteristics
All the bike builders Jesse James, Indian, Larry amongst many other and this is the first I’ve ever seen this done by genius that lives in the woods somewhere in the northwest I’m guessing
This whole project reminds me of the quote from The A Team movie - "Overkill is underrated!". Excellent work gentlemen.
This channel consistently has some of the most interesting and imaginative projects. That show is trending. I have to admit I was skeptical when this car was photographed before the build process began but seeing it come together it looks amazing.
I’m a motorcycle guy. This build is awesome. Not something I would drive daily, but when I wanted to make a statement, would be perfect. It’s awesome. Everything I would do is getting done in this build.
Awesome craftsmanship!!
Love how you are not just making it functional, but a work of art as well! Love the trellis frames!
Check out 6:08. A happy coincidence when the handlebars are held up it perfectly frames the word 'PREMIUM' on the beanie hat.
Detail focused!! Awesome bike build!!!
I would like to see you build something with Matt's offroad recovery. I think y'all would create something amazing. Cool to see the ranger is coming to Texas.
Brilliant! As ever. That 'triple clamp' would be a Top Yolk. Super interested to see how it handles, especially with counter-steering as you would ordinarily do on a bike.
I been glancing in on you guys for years now … and while the other builds have been AWESOME!…. Watching this man do some extremely custom off the cuff work …. AND IT WORKING?!!! Simply amazing . This man is a damn genius!
Seat tube - back tyre.
Just be sure when the tyre expands at speed and the seat is at full droop that the bike doesn’t try run over itself.
I love that CZcams recommended me this channel.
I love the flowing line through the whole bike that you created with the tube frame, makes it look almost elegant(from a distance😂)
Love how you took that extra time to ensure that shock mount stud matched the inner radius. That was totally PREMIUM
Im so impressed with this build especially. You can get such a good look into the mind of Ethan as a fabricator. His problemsolving and designs are so inspiring to see!
Is it drivable
@@elarrayhesohit4479 Something does not have to function to be impressively constructed
Like wood and rock to a sculpture, this guy turns metal into masterpieces. Amazed at his talent.
I love that you guys put your engineering genius in this direction. Awesome
the sickest motorcycle I have ever seen, amazing
I cannot express how excited I am with both this gem of a project, and the future of your channel! Been watching for a good few years, seen so many of your builds, and while all of them have been great, this one in particular feels like a huge step forward.
This is absolutely an incredible work of mechanical art. Seriously gorgeous.
I usually don't care much about vehicles but I want to see this move.
I look forward to seeing it.
Ethan! You should use a bigger diameter master steering cylinder, so it can be more compact. Change the leverage to compensate for the shorter stroke.
You have come so far in your abilities Ethan you are so gifted. Finding a group of people that have all these talents is such a rare thing, especially in these newer generations. Everyone on your team as their own special talent or ability, even Will is useful in his own way. J/k love you Will! Anyways keep it up guys your content is mostly the stuff I look forward to on here. You keep me rooted to the PNW too, which is nice being from PNW and having to suffer down here in SF. Hoping to make it to the Gambler this next year so we will see!
Looking so good pal it's truly beautiful I'm looking forward to seeing it finished
Came here from Shorts, subscribed just to hopefully see this thing run at some point. PLEASE post some operation vids, I'm dying here! Love this.
This episode is giving me strong "Monster Garage!" Vibes!! Awesome work guys! Keep up the amazing material!
We're not going to talk about the editing and videography work put behind these videos? I freaking love the videos. Keep em coming🙌❤
A mud gaurd/flap on the underside of the front swing arm for the kick up'd road as well as an integrated back guard might be a good upgrade. This build is mental!
I was a little bit sceptical about this build in the beginning, but now I totally love it. Everythink looks amazing and work that you put in is pure quality. It will be interesting how much dirt and rocks will this two huge tyres throw in a rider's face and back, haha.
I would not want to fall with that giant tire right behind me :D Otherwise really awesome build!
Yeah, I keep seeing someone slip back on the seat a little from a bump, and then being whole body pulled through, groin first folding into a human meat squashy thing... I hope it will have a mud guard, or something to prevent that... Also the back of the seat bar is very close to touching as the suspension bottoms out.... Crossing fingers for them!
@@jeffkent6886 was looking for this comment
need something between the back and the tire. that looks deadly but sick lol
You are the mad Max!!! Love you videos and mad but genuine ideas for this project.
Thats so freaking coool!!! Cant wait to see this project finished
Is this Batman’s or Iron Man’s motorcycle? Check out our podcast Sent and Bent
It's a Mad Max bike
It's grind hard plumbings motorcycle, what do you mean
It’s Schwarzenegger’s get to the “Monstah Choppah”
Iron Deficiency Man's motorcycle
Batman 100% dude!
Considering how much weight you're going to add to the center, I think you should double the springs front and rear. Don't forget that you won't always drive on flat roads!
The problem with suspension is that if you for example have 3:1 leverage ratio in linkage/ swing arm, then the actual spring rate at tyre/ wheel axle is spring rate divided with 3^2=9 -> spring/9. Or if leverage ratio is 2:1, then actual spring rate is spring/2^2= spring/4. That is one thing what most of the people, if "any", knows. And that is why typically these trial and error fabricators end up doing way too soft suspension.
(Typically 600/100 street bikes have 2:1 linkage ratio, so when you use those shocks, keep that in mind).
And also, if you want to use stiff spring, and you want to suspension to feel soft, then you just have to revalve compression damping and decrease compression damping, and suspension will feel soft even if you have (very) stiff spring.
I'm beyond impressed by your work and your shop. Amazing
Incredible idea, I love this thing, even gives a purpose to those giant chopper back rests; keep your back from getting ripped off by the tread.
I think it might get harder to lean with the tires actually spinning because you’ll have to fight that gyroscopic force from the huge rotational mass of the wheels…but I could be wrong.
I cant wait to see how this thing handles!
Looks like it's gonna be a handful in the turns.
That is one of the best custom builds that I have ever seen in my life!
You guys are are like mad engineers with great machining skills !
My grandfather was a tool and die man for Case. My father was a great neuro scientist and taught at Stanford. You guys are very impressive and they both would of loved your channel.
Merry Christmas !
I can’t get over how insanely smart these guys are like it’s absolutely mind blowing
yes
dude, I just found this out from reels. y'all actually making my childhood imagination bike came to life😯🤯👏🏼
Magnificent piece of high-level craftsmanship. And so much creative. It's a pleasure to look at.
Cant wait to see how this turns out. That back wheel looks scary close to the rider though, what kind of plans do you all have in mind for fenders if any?
Was thinking the swing arm should be a foot longer at least and then a full cowl fender ….

HI I LOVE YOUR VIDS
Suprisingly NOT clickbait!!! wow man great job!
What a beautiful machine! put a smile on my face! great work cant wait to see the rest!
About 10 years ago i had a Kawasaki nomad 1600 bagger. I was wearing out rear tires because i commuted to louisiana from florida every 2 weeks on it.. but it only wore out the 2 inches in the center of the tire. at 250 to 300 a piece every 4 or 5 months... it was getting old. I installed a very well researched car tire that looked awesome on it, and rode so amazingly well. It took a little getting used to becasue of the shape, but it actually solved some driving and handling issues that i didnt like. And I never work out another tire on it till i sold it 5 years later lol,
I bet that thing youre building will drive like a beast. I would love to run a few laps around the city on it.
Also.. with the soft ride, you may need to slap a skid plate on that baby lol
This is sick. Stoked to see this thing run for the first time
These deep Ethan builds are pure gold. Keep up the good work!
I see the light at the end of the tunnel. Most channels begin to suck when they get big. You are now becoming big and so far still staying the course you were on before. You might might actually make it to "huge" and still be true to your beginnings.
Congratulations are almost in order.
This is badass glad you were on the ole home page today. 👍
It's not the "softness of the suspension" but the angle through which the force applied to it is being generated, that is creating this effect.
The closer a suspended object is located to it's supporting anchor points, the more force is generated through the supporting structure.
At 120" you have effectively doubled the mass applied to each of those shocks to what would be applied under normal placement. You're at around 180" which is approx. 600% times the mass in force applied to that frame and the shocks.
I hope you’re welds are solid? Would reccomend increasing the minimum rise height to alleviate the extreme stress and get an engineer to check it over before riding it, lest it snap in two and have that rear wheel crush you.
Fellow Pacific Northwestern here really thinking about that gyroscopic motion you might have with that thing hope it all works out badass though love you guys's toys
New fan I love this chopper build I want to see it finished keep up the great work😃😁
i miss these kind of channels... now its just a bunch of figure head "influencers" definitely subbing
Ahh they’re still around, just need to look around a bit
This bill has been addictive of horses on my TV for this one here three times and on my phone all you can say is premium premium!!!👍👍👍
I cannot wait to see this beautiful beast in action. It's like a motorcycle rock crawler. Surely it can go anywhere
best project build on youtube right now! 🔥🔥🔥
That bike is coming along so cool Great work!
This guy has more Talent than all the Motorsports shows in the last 25 years ,
Remember these TV shows have sponsors and free stuff ,
This guy is in his own Garage using recycled EVERYTHING !
YOU JUST A THUMBS UP 👍 FROM ME
Mannnn i cant wait for the full interview . subscribed good work keep it up
Can’t wait to see it run. That was one of the most interesting videos. I have seen in a very long time. Then again, I do like this sort of stuff.
I love these solo Grind hard productions, love the other guys but I mainly come here to see what this guy has concocted
This is basically the coolest thing I have ever seen. These guys are complete geniuses
You are a master!!! Love these bike. But your skills are on another level.
Excellent work great pivots, you got some trick skills my friend ❤
not only the mechanical skiils, the music too! love it
