I'm convinced that being a presenter at donut requires some of the widest skillets of any profession. You have to be an engineer, mechanic, fun speaker, driver, and be able to convey some complex topics in an easy to understand way. Good job guys (and props to the guys behind the camera as well, we don't see you but we know you're there)
Unless you can't do any of that. Then they let you crash their cars, they all have scripts wrote for them. And only 1 of them is an actual mechanic. None of them are engineers lolol.
But keep thinking they're the smartest people on the planet
@@sunny_froyo Mad? Lol
My skillet is so wide. Its 14 inches!
@@sunny_froyo doesn't Jeremiah have a bachelors in mechanical engineering and a masters in biomedical engineering? Not saying that they're amazing mechanics or anything (hell, Jeremiah went into comedy after getting his degrees,) but that doesn't mean they aren't qualified to do what they do, which is make a comedy car show on CZcams. Them going through with dumb ideas with their car builds is part of their charm.
@@whimsicalstray he’s more so complaining about the fact that donut pretends it’s a group of guys having fun building cars when it’s a media company who hired these guys as presenters.
Justin was one of the best additions to the channel. Intelligent & great show of character always.

💯
For sure
Couldn't agree more! We could tell he was nervous at first but hes really shined. He has "the shine"
Kinda like him being in everything and kinda want him to get his own segment sometime soon. And I secretly want his workout regimen; dude is jacked.
Jeremiah's laugh is hilarious 😂😂
Literally
Man is pure gold
You mean Tom DeLong?
Came to write the same thing!😂
I feel like he reminds me so much of Kevin Nealon.
I felt like he was struggling to get air at one point lol
Jerry's laugh is priceless
I think this video demonstrates of how hard this stuff is and how good the Mythbusters really were at it. That said, I really like Mythbusters-like episodes, so keep it up!
My day is always better when Donut posts

As some people have already brought up, without training wheels, at speed, steering will actually tend to be opposite of what might be intuitive. This is because it will cause the bike to lean. At speed, most turning is done by leaning. If that dummy isn't held more firmly upright, it will turn the bike itself as it bounces around and ends up leaning to one side. Hope this helps. :)
Their whole concept of steering is flawed. The handle bars need to “wobble” to keep the hike balanced. So both options inhibit the bikes natural stability, like a rider who holds the bars tight…
Called Counter steering*
Another thing that blew my mind - especially since Jeremiah is the one who said it- was the weight of the dummy. Weight is 100% a factor in the amount of damage done/injury inflicted ESPECIALLY in a motorcycle accident. The fact that they ignored this blew my mind. I love this channel but this one was clearly flawed
Glad someone pointed it out. Lot of flaws in this one. On top of the whole counter steering thing, they used the totally wrong servo for this. No where near powerful enough to move the bars with a longer control arm (which is definitely needed). Also needs a servo saver to decouple the servo from the bars.
I think your steel cable solution for the steering was actually quite good. Instead of using a flat bar as a lever on the servo, you could use a single spool. Have the cable from the right handle wrap around counterclockwise, and the cable from the left wrap around clockwise. That way, you can have much sharper steering inputs that are much more linear. You could even add some pulleys in front of the spool to reduce the force of steering feedback.
Same thing was going through my head 😂
Lmao that is exactly what i thought as well
YES, THANK YOU!
And use stronger servo
Guys!
You don't steer a bike with handlebars you also use your body. You'll never be able to turn any corners with the dummy because the dummy is not leaning into any of its turns. When you're turning the bike the dummies weight shifts to the other side of the bike making even harder to turn. You have to keep the training wheels on. Also replace them with something smaller and lighter.
Jeremiah have a look into the physics of riding a bike.
What you find is when you turn a bike to say the left you'll turn the bike ever so lightly to the right to shift your body weight to the left then turn left. It's a really small adjustment but makes all the difference.
Man, when Jeremiah starts cracking up when the bike wiped out on the 15-mph run, got me laughing good.
Jeremiah's hiccup laugh is so hilarious
I love how positive this community is. I really do. You guys are amazing creators as always, and the community is wonderful as well!
There are a lot more people in this community that could be much, _much_ more positive, but we don't claim them.
But hey- with millions of subs, I think that's pretty good!
Adam pushing that bike seriously reminded me of my dad letting me nose dive 3 steps into getting me going 🤣🤣
Damn, Nolan's Imperial sitting that low looks pretty good from 6:26 to 7:00
Next episode : "How We Transformed an Imperial into a Lowrider: Air Bag Suspension Upgrade with Donut Media"
That coleman has survived some brutal testing. It deserves mvp for making it thus far
You could use Ballistic Gel Dummies in the future. See what internal injuries (and external lol) they sustain from this kind of thing.
When it comes to welding, slow and steady is the pace! TY guys!
$5 says you forgot that motorcycles countersteer on two wheels at speed and your RC servo is running for the normal steering you'd do with the training wheels attached, so it goes the opposite direction you want it to when the training wheels are off.
Dang dude, you're smarter than my 2-year-old nephew. I bet there's no way these guys thought of literally the first thing you learn riding a bike despite that they both know how to ride a motorcycle.
It's almost as if they were dealing with a 200lb inanimate object that is incapable of using muscles to control the lean of the bike and itself.
It's almost as if the bike would drive perfectly fine if a human being was on it, but they're going to crash it into the side of the vehicle so they need to come up with a way to accomplish these tasks with servos and cables.
I'm sure they'll hire you and pay you 500k a year when they read your amazing comment.
@@flyingtentacle7631 🤓
@@flyingtentacle7631 You don't need a rider's shifting weight to control the lean. The lean should be completely controllable by countersteering.
That is not to say this would be easy.
First for hardware: the steering system would have to be extremely rigid and responsive to initiate a countersteer, yet still allow the handlebars to move freely the other 90% of the time to let the steering geometry control the wheel orientation. The system would have to be robust enough for quick and powerful steering inputs--enough to upset the bike's balance--but also able to be completely disengaged and nearly frictionless most of the time so as not to affect the bike's self-correction of balance.
Even if that hardware makes steering possible, it would be extremely finnicky and damn near impossible to actually control without being on the bike, feeling its balance, or being able to shift our weight. Controlling countersteer would be impossible guesswork. Here is where the software side comes in: the countersteering routines could be automated.
For example, say the operator gives a left turn input. The algorithm would flick the handlebars right with a magnitude and for a duration calculated based on the magnitude of the operator's left turn input. Then the steering system would disengage to allow the front wheel to reach the equilibrium angle in the turn. While mid-turn, the turn could be made sharper by steering the wheel momentarily to the outside (right) of the path of travel, or made shallower / cancelled by flicking the wheel to the inside (left) of the path of travel. Translating the controller's intuitive inputs into the correct countersteering operations would require calculations including some constants: the specific steering geometry and weight of the bike, and variables: the magnitude and direction of the steering input, a gyroscopic sensor to know the current lean angle of the bike, and a speedometer to account for the speed-dependent drag characteristics of the bike and the speed-dependent gyroscopic properties of the wheels.
Clearly there's no small amount of hardware and software work required, but the fact is it should be possible and if it works, oh boy. I'll be so excited!
@@ricardocruz4235 or a strong enough gyro that is inclined left or right with a servo
Jeremiah's laugh sounds like a ported RX7 idling !!!😄😄😄

Whenever those words are spoken, it’s definitely going in the final cut 😂😂
I love y'all !!!! Fantastic work! The content is great as well. Thank you so much. Gave me a huge smile while I'm in rough times. Thank you!

Controlling brakes never entered the plan 😂
Balance and steering is hard, probably need power steering and a computer involved on the bike that can actually feel forces and correct with steering.
Super fun video as always!
They need to a small powered gyro to provide balance. That's the issue. They should be able to get one that runs at a relatively slow speed to keep the bike upright while still allowing steering inputs to have an effect. The real way to do it would be to have a gyro with a motor on the box to steer by using lean, but they only need to go 50 or 60 feet.
You guys are like Next-Gen Mythbusters. I love it!
The whole concept of this channel is awesome and the fact that it's just a bunch of like-minded friends having a good time doing what they love is everything that makes Donut🍩 so special. I hope you bros can continue in this endeavor for many years to come.
I can see jeremy is really enjoying the motorcycle video series.. and i dont mind having more too..
HEY FAN, I HAVE GIFT FOR YOU 🎁, SEND A DIRECT MESSAGE..
Agreed
As someone that has been involved in rc car racing for over 30 years, the radio equipment used in this hurt my soul. lol. A 1/4 scale steering servo would have handed this (with a better servo arm) and a decent transmitter/receiver combo is really required to keep this from running out of range in a short distance. It was an entertaining video that looks like a lot of fun to make. Great job Donut crew.
The laughing tho so perfect 😂
Jeremiah's laugh 😂 "bro shift up!"
Steering a bike isn’t as simple as these guys think…it’s super complicated in reality…turning RIGHT it actually needs a little LEFT input to start with to tip the bike and vice versa hope this helps ❤

Yeah, I was thinking this going to be a countersteering nightmare.
yeah I'm surprised jeremiah didn't notice that considering he rides bikes
@@MrSketchyCharacter not just counter steering.
Balance. Bikes are somewhat self correcting when it comes to balance, that’s why you should never be death gripping your handle bars, the front wheel needs to be able to react to the road, letting the tyre do magic tyre physics to pull the bike straight.
By limiting the handlebars from making small natural movements the bike is no longer self balancing.
@@leonjohansen1818 a scary amount of people ride bikes without understanding the technical details of how to ride them

Thanks Justin and Jerr!!
Love the content!
Always a good day when there's a new Dout video. But a new motorcycle video? Best day of my life
Maybe turning it into a 3 wheeler will solve the stability problem, or like a wheely bar type of thing
You mean like adding two wheels to either side kind of like training wheels? Like what they literally did? Dang, you're a genius.
Actually, three-wheelers are notoriously unstable. Three-wheeled ATVs were banned in the states in 1988 for this reason. Bikes are much more stable but only if steering is handled correctly, which it was not in this video.
I was really thinking more in the lines of a wheely bar, like you get on dragster to prevent them flying off the road, kinda having them flare out to behind the bike instead of just the training wheels. with a long enough wheelybar and the right angle in between the "legs" of the bar it should work
When I was a kid, there was a vehicle that had been T-boned by a motorcycle doing roughly 100mph (running from the cops). Our regular gas station had towed it away from the accident and displayed it for a couple of weeks. The side looked like it had been hit by a big truck. Even 30 years later, seeing that damage, the impression sticks in your mind. (Keep CZcams friendly, and let's not discuss the driver of the motorcycle.)
I bet the driver looked like ground beef after that
I've been following for like 4 years now. This is the BEST content I've seen. Obviously I love all the others too; but this piece is literally the new pinnacle of Donut
9:37 Seeing Low Truck still being used as a practical company vehicle makes me very happy.

Nothing makes a great morning like watching a Donut
and some coffee
I would have LOVED to build this thing with you guys!
Really love seeing Jeremiah and Justin doing their thing in the wild.
Just casual 5am Donut posting
Looks like countersteering is the issue. To initiate a right turn, you start by turning the bars slightly left. Once the bike leans to the right, then you start turning right. The Training wheels either need to keep the bike from tipping at all, plan for countersteer by tapping it the other way 1st, or be able to transfer the dummies weight side to side.
Nevermind the poorly positioned dummy. Playing havoc with the balance of the bike or servos meant for 1/10 RC cars 🤣
Love Justin, love the motorcycle content
So, turning the handle doesn't really steer a bike, you need counter-steering and leaning. But I just love the episode, you guys are awesome!
J-bear and J-dog are killing it, loved this one boys, cheers 🍺🍺🍺

I like how i could tell that, you guys were having fun
That short explanation of a carburetor slide saved me hours of pain
Justin and Jeremiah make a great team. Awesome episode.
@DonutMedia I’m glad to see that you guys still use the hi low tacos for other videos!

Their Sketchiness has achieved new heights. Edit: You know they make a lot larger servo motors for giant-scale RC Airplanes.
Bruh youtube is boring without this channel like i be waiting for yall to post cuz every video yall make are just so useful and entertaining
This was fantastic!!!!
that was totally wicked
Yes yes yes!! Motorcycle with Jerrbear content! 🤘🤘
Just curious, are you guys gonna do more motorcycle content? Like a build or something? Love the vids!!
Real myth busters stuff right here
Awesome video! Looks like loads of fun.
Suggestion for the remote steering system: if you attach the rod closer to the center of the handlebar, you reduce your leverage but increase the amount of steering you can do. Same goes for increasing the length of the piece of metal attached to the servo.
The training wheels you could make a bit wider to stabilize the weight of the dummy, and you can increase the maximum steering angle by angling the wheels up a bit more.
Jerry’s laugh is the best😂
Jeremiah's laugh when they tried to hit the tire wall was hilarious 😂
