The World's Most Dangerous Motorcycle Gets an Important Upgrade! 

Looking at the fender I kept waiting for Paul Sr to come in and yell at you.

Glad it’s morphed from monster chopper to “ world’s most dangerous motorcycle “ responsible 👍

I can't stand why so many people just want a build done immediately. Why they complain about too many videos. Why there are too many projects. Why doesn't it run... On and on- I see it on all the channels i love lately. It all takes time and it's awesome seeing people figure it out. I appreciate all of the effort and content ! Y'all are killing it! Keep it up!

Hey buddy!!😁. If you place a motorcycle chain ( upright ,not on its side ) between the tyre and the fender, you'll have the perfect gap and bracket possitioning. Cheers pal!! M.

Tip of that rear fender is going to flex on the first good bump and catch on a tire lug

Since the chopper will vibrate quite significantly I definetively think you need to bend up the tip of the fender so it does not vibrate down into the wheel and catch on one of the nubs on the tire and get destroyed. Match the bend with the same shape/angle as the seat so they will match.

An old school fender spacing trick was to use a 1/2" or 1" rubber Hose between the fender and the tire. This gave the fender some clearance for when the wheel expands while riding the bike and keeps the fender from rubbing the wheel. I would not want any flex in a fender as well as that will allow it to get caught up in or rub the tire and cause possible catastrophic issues for the bike or rider. Love the bike by the way!

Lay a couple pieces of old motorcycle or bicycle chain on the tire when you set your fender. Weld it in place then pull the chain out. Lot of guys use this method to get a good fender clearance on chopper builds.

This is the type of fabrication we all fell in love with back in the day! Fail till its perfect and have fun along the way! I love GHPC videos sooo much! Wish i could find some buddy's like this in Metro Detroit!!!

Don't forget to put rubber washers on the fuel tank mounts for vibration

That rear fender, with the edges cut out, is going to allow the tire to throw dirt all over the rider. The tire is going to need to be covered edge to edge all the way to 1 o’clock or so. Maybe more.

Interesting. Gyroscopic effect is not primarily what keeps bikes upright, it’s gravity steering. Forks are designed so that if you lean a bike it steers into the lean, which is self righting. I look forward to updates about handling, I assume it will be very bad.

this whole video makes me think of growing up watching monster garage. and watching jesse james build fenders and gas tanks from scratch .

Back in the 70's in metal class we made funnels. When we folded over the sheet metal we placed mig welding wire in the crease. This helped add stiffness and gave a more rounded edge.

That back tire is going to need more gap from the fender. Any little bit of dirt, rock, or snow could easily get jammed between the tire and the fender. Orange County Choppers used to put sections of tubing across the tire then place the fender on top to keep the same amount of gap and help judge proper fender mounting.

Once you get the bike running you could lift up the back tire and while its spinning use the angle grinder to get a consistent rounding on all those nubs. (And temporarily mount the front tire on the back end and do the same) Probably would improve tire balance and reduce the vibes on smoother roads.

We need a dope poster of all those CAD designed parts laid out.. That'd be super sick. For the nerds 🙌 Class work as always boys!

Thank you for getting back to the normal content.

That is really coming together nicely. It is amazing how much time gets soaked up in the little details, but that is what makes a really special build in the end.

The foot rests! Make them LONG. Will give you more leverage to balance!

I hate to say it.. but why on earth didn't you just leave like 2-3 inches between the fender and the tire? Unless you want it to work like a mud scraper (a la farm implements), I just don't get it.

Plenty of people may disagree with me here, but I feel Ethan sent Edwin and Will to Florida on their own so he had time, and peace and quiet to focus on his own creativeness, without the distractions! I've loved seeing Will's build skills improve dramatically since he came on the scene, though I honestly loved this video, just watching Ethan work, with some really small side commentary. Some beautiful camera work, with it nearly all being fab/project related. Sometimes there just ends up being too many random aerial/random shots and side stories thrown in, that some vids feel like they're being fluffed out. Obviously, I'll still catch all of the videos, but this felt wayyyy more back to the original GHPC stuff that I fell in love with! (Don't take this the wrong way, you're one of three channels that I regularly stop to watch, everyone else can wait till I have a moment :P ) But I definitely felt the peace and quiet in the workshop with Ethan getting to do his best work. Maybe I just feel I'm too similar to will, Impatient, wanting to rush things, giving it a full send, and farrrrrr too easily distracted by conversations and other things around me... Ha ha ha! Great work by the whole team, even when the whole video is nearly entirely one man talking to the camera, I know at a minimum one of you is still hiding largely uncredited behind a camera, and Edwin does epic work editting everything into great vids! But in summary, I LOVED this one, please Mr Editor Edwin, more like this from Ethan where he really gets into explaining and showing what he's doing!

You guys need to get a ventilation system in that shop. Breathing in cancer

When working with sheet metal steel or aluminum make sure you aneal the sheets after working it, you may have to aneal it several times. Some of the problems you had with the fender would have been alot easier. You can heat it in one of 2 ways, the best way is to soot the panel with an acetylene rich flame and the adjust to a neutral flame and burn the soot off and allow to air cool. The other option is to use propane and heat the panel as hot as yo7 can and then let them to air cool

27:25 "once these wheels are moving at a decent RPM will be a giant gyroscope that does not want to lean so will hold itself up". Once the wheels are spinning at a significant RPM, they'll want to maintain their current position, regardless of what that position is. This implies that if the bike is already leaning, it will continue to maintain that lean rather than auto-correcting itself to an upright position. The notion of 'uprightness' isn't a factor for it. Bikes doesn't automatically correct its lean due to the gyroscope effect. The primary reason bikes can auto-correct and maintain balance is due to the geometry of the steering system, specifically the trail. If this bike has minimal trail, it will not auto-correct effectively. Similarly, if the steering system lacks responsiveness to these auto-corrections, the bike won't maintain balance as expected.

Monster chopper is easily my favorite series on this channel

There's little more humbling and satisfying than watching a skilled man in his element, doing his thing, while imparting a wealth of knowledge, in a thoroughly entertaining fashion. 😉👍 PS. That rear fender brace looks like a knuckle duster for a centipede! 😂

YEEEEEWWWWWWWWWWWWW!!!!!!!!!!!!! Ethan is my hero. Been a fan for years now and so look forward to the Friday posts. Dudes just out there livin the coolest self-made life.

When you are done with this build I would love to see you guys make a bike that is a rideable and road worthy something like a Triumph Bonneville bobber style but with your unique touches and styles. Because the monster chopper as been one of the best builds and I would love to see more like it

New shop makes room for new tools. New tools mean new skills. New skills mean better builds. Better builds mean more views. I think Ethan has it figured out. Also, the video itself is great. It's full of interesting shots and the quality is high, but it still feels like you are almost in the shot with Ethan, and the videos come across as very authentic and not overproduced. You guys are killing it all around.

That thing is epic. Just remember the tyre expands when speed increases so u need more clearance to the fender.

Dude it would be a travesty to paint that. I like the rusty frame and clean bare metal tins!

9:00 Ethan's smile already made my week

It was kinda refreshing to spend a day just with Ethan. Love the whole crew tho!

Nice work ! I love the looks of that fender. I hope it's not mounted too close to your rear tire, though. It reminds me of a chopper build off where someone's rear fender was so close to his tire, that when he got up to speed on the highway the tire expansion made it rub on the fender. Running through any mud should result in the fender slicing it off and hurling it onto your back. Thanks for sharing your great work !

Great camera-work on this one, Steven! And those timelapses of the fog look soo good!

With all the work you put into your projects you really should build a garage to store them and keep them out of the weather. It could double as the Grind Hard Museum.

The fact that you have created this from scratch is insanely impressive to me. Just about anyone can bolt parts onto a car/bike/etc, but few possess this level of skill and patience. The fact that you sit and study and ponder every piece just confirms that. Can not wait to see this thing finished !

If they took the rust off that thing and shined it up a bit, it could literally go in an art museum

On the rear fender bracing…lay out the edges, then drill small like 1/8” holes like every couple of inches. Then rosette weld from the back side. No visible welds and the small rosettes will draw the metal the same direction as the curved surface.

I love this guy. His energy. His brilliance. His creative flow. It just motivates me to do better.

These projects are more art than vehicle. It's amazing how well they all work, but that doesn't change the fact that it's an artists work.

Hexagons are Bestagons!

I love the dog opinions

man! to me this bike and the 2jz tractor and mini jet boat are probably my very favourite builds from you guys! love everything else too of course! that 2jz because you put it in a garden tractor 😂👌 and that bike because you really surpassed the quality and amount of work you put in everything else in your builds! this thing is gonna be awesome!

Woah, I dig the Ethan voiceover at the beginning!

One rock stuck between them lugs and that beautiful fender is toast.

Cool stuff . Thanks for the update .

I see that bike in the next Mad Max movie...

Ahhh thank you. I am so glad there is a fender now. Much more safe, congrats yall. Its a sick build.

Duddee fair play this project is AWESOME! I found your channel through this project, and have since binge watched everything, but I love you general video style, like it's a longer wait but you get an hour where there is actually a load of progress, rather than daily videos with next to no progress! Keep it premium brothers!

Why didn't you do hexagons for the fender mount brackets?

Ethans problem solving skills, attention to detail and patience in execution, is so pleasing and never ceases to amaze. "I'll get back to you when I have a solution." Says it all. As always, great camera work and editing ! As Always, May God Bless you and yours! 😇

This is the grind hard that I started watching this channel for. It's great when loose scews Willie isn't running his mouth.

Please make a video using a chainsaw engine and a diy go kart frame

Wowzers, that is one gnarly beast. I LOVE it! Are test drives available?

Man I really have been enjoying this project so so much. This video was one of my favs so far.

I’m enjoying watching your journey into sheet metal work . I was a steel worker/fabricator for many years but never had the chance to do sheet work . At school we made ashtrays but would love to just go in a workshop and get to play with an English wheel and all the other tools for a few weeks. Loving this entire build 👍

I love how you say every new bit is your best new bit ever made lol gotta love your own workmanship that's pride

Been fun to watch Ethan get better at metal work over the years. Dude, killing it. Keep it up.

look forward to seeing the finished article. looking good so far.

Extremely satisfaying to watch this project come together! Keep up the good work!

I’m loving how the rust is looking as a paint job. When you paint this, have the colour combination of bronze/brass and silver those 2 together look awesome

I mean I like to watch the Swindle Bros swindling their projects too.... but it's these big projects making me sit down with my Saturday morning coffee to watch in its entirety. Seeing Ethan develop his skills over the years.. these metal shaping is sweet! Can't wait for returning to the fire engine, and maybe building a chopper with Stephen at some point.

9:30 it’s probably just me but I really feel like it would looks so cool with like another piece of metal between the fender and and seat and make it look like knight armor like how it overlaps almost if that makes sense Maybe even make it’s like a hole for air flow like close that gap in between seat and fender so air that under the bike will get pushed up through it over the back tire again if that make sense

I'm 73 and my grandfather had a tire shop in Nebraska, around here are some of the retreating tools that my Dad use to use. People use to use everything for every drop they could.

Oh my gosh! I’m soo glad to see a fender on the rear! I have been writing you about it!!

The videography is excellent and i love the long videos where parts of the project and started and finished in one video. Such a nice change from most channels where its just numerous unconclusive videos

Watching 52 minutes of Papa Ethan fabricating is so satisfying.

Your talent for fabrication is truly exceptional! Watching your skill and creativity in transforming ideas into reality is inspiring. Keep up the amazing work💪

When you said "fender mark 3" I immediately thought about Iron Man when he build his suit...maybe some food for thought? lol

great work as usual - agree with other comments about needing clearance between the tire and fender for tire growth, vibration and debris. Rule of thumb is 3/8" for a tight fender, but I would go bigger on this beast...

this is going to become a historical build that will be known in the history of motorcycles

Make a framed blue print of all the cad for the project and sell it on your store. Gringhard at the bottom. Bike side view at the top and cad in the middle. Would be clean for a tshirt or poster

The suspense on this series is craazy

Beautiful, by far the best vehicle build of RU-vid and now it just needs a turbo and nos

The most happy time I ever spent on this planet is the time I spend watching your videos ❤❤

Next episode “Will It Run?” Can’t wait. Hope it is controllable. The extreme downhill and trailering on the mini truck were very entertaining.

That things gonna be awesome! I can't wait to see it ridden.

Oh and you are brilliant! I really enjoy watching the design & fabrication! Thank you very much for the great content.

Thanks for putting a fender on! I can now watch again!

The bike is wonderful - I'm just a little disappointed about one thing: No hexagons! Neither on the tank nor on the fender - what a shame! 😊 Very impressive piece of art! 🎉

I think it would be really cool if you made the mudguards out of aluminum tube to continue the tube chassis aesthetic, then used like a plexiglass shield. Kinda like a TVR Sagaris spoiler

I've been watching you guys since the rotating treehouse days, and I don't think I have ever commented on a build. But, I'm sorry if it hurts someone's feelings, that fender murdered the cool, unique look of this bike. It just SCREAMS Orange County Choppers. Like last season OCC when Jr. was gone.

Elite fabrication skills my friend!! Inspired!

Meanest little crew of mechanics making fun things 💪💪

Glad to see that vital piece going on the build

What can I say? That fender is at a whole new level of craftsmanship. Oh and I love that rad cover, it's radical man

That fender is going to get really hot if you ever get up to any speed... But looking really premium :)

Layered scales for the fender!! For a second in the video you had them overlapping and I thought, oh that looks amazing.

You guys are killin it. Great video great music. Can't wait for this thing to be movin

best part about there videos is looking for future projects in the background

Long format videos are awesome! Chopper fenders usually are laid on the tire with some thin tubing underneath to gap them consistently around the tire circumference. Just a thought. Looks good!

Loving the looks of this thing. Great job as always just keeps getting better and better

Excellent job on the fender. You are one hell of a fabricator. Love your videos.

You guys do the worlds most 'premium' stuff. Its my dream to be able to do this kind of thing with guys like you

I love the beginning when you were cutting the tires and had the time laps going because you were all over the place doing work, but in the background you could see the dog laying there and they didn't move a single inch the entire time!! Gotta love the fur friends!!

I'm surprised you didn't make a fixture to turn the tire for consistent lug removal. Impressive workmanship so far! Keep up the good work!

This is simply amazing, thank you for sharing
