1:42 Im a metal fabricator. I dont watch this channel for tips and tricks, i watch it for entertainment. So keep up the good work 😉❤️ My tips for you? 1. Gloves. ALWAYS wear gloves, and tuck in any loose shirt material when using an angle grinder. toull thank me later when you DON'T lose a finger or gouge your abdomen after it binds and kicks around at the speed of light. 2. Clamp EVERYTHING. this not onoy keeps the material in place, removing one of the many variables involved with cutting metal, but also gives the tools more constant contact with the material, making it cut easier with less force. Overall improving safety, efficiency, and reliability of your cuts. If i think of more as i keep watching I'll put them here ❤

You need to add a foot rest that is out in front of the mono wheel plus a little more weight in the front. Part of the problem you're having is that there isn't enough weight in the front. On top of that without a solid foot rest it's hard for your body to balance and control. I'd also recommend making the rollers out of a different material, but I think you know that.

While the goal of the monowheel is to be contained within the monowheel, yours is a bit... small... but since you've got it build, a step by step suggestion as a jumping off point for mark 2! Step 1. Extend the foot rests in front of the monowheel with a comfortably wide stance. The forward weight will reduce forward rise from acceleration. Adjust weight accordingly (but do not completely negate rise.) The forward, wide stance will allow you far greater balance, and thus turning. Step 2. Add a wheel on the foot rests, but with high resistance, potentially a breaking system. This can be a single wheel in the center or, more preferrably, two small wheels on the outer edge for stable and safe breaking. These wheels will not touch during actual driving, maintaining a "monowheel" status. Step 3: HELMET. You got a light bonk in the video, but that could have been quite a bit worse. Invest in a full face DOT helmet if you're going to leave massive bolts at temple level. Are extra wheels for breaking/safety cheating? Do the wheels on a jet make it any less of a jet? If you are willing to rebuild the inner body... lower the bottom rail for a more "cruiser" feel. Lower center of gravity should help with canting forward and back to offer more head clearance. You got brained because you couldn't shift weight to the other side with no foot brace and the risk of a lobotomy by ducking through the tiny gap.

Here are a few tips to improve on the design: 1. Increase the weight at the bottom. You want a low center of mass so you stop rotating inside the wheel as easily. 2. The ratio from the immer wheel to the outer wheel is way too low. Put on a bigger wheel, which will prevent you further from rotating inside of the wheel, due to the higher energy required from the motor to spin the outer wheel but it will also increase your top speed. 3. Put some foot pegs further out. You are way too cramped in there and it will also make you spin less inside the wheel, due to you being stretched out further.

I think this is an awsome little thing. In its current state it's cool, but lacking, and both I an many people would like to see this functioning to its full potential. I think one good idea would be to add balast to where you want it to balance, as well as adding balasts that extend out to create a more triangulated center of mass to keep it more balanced. Another thing you could do is to provide more clearance to the head by re-shaping the upper brace to fit the contour of the drive wheel, as well as make the foot rests wider and move the seat back to create a more comfortable position. One more thing would be to fit inner tubes with real tires to create a more comfortable ride, and to add brakes (just simple cable-driven brakes would do), that way you wouldn't have to use your feet to stop. There's much more you could do, but these are the easiest improvements I could think of that wouldn't require building an entirely new model. I hope you see this comment and consider it, I would really like to see this bike updated!

the balance Issue results from the simple fact, thast the bike ist far too small, and so he has to lean out to one side constantly. the center of mass is not the problem, actually it would be better, if the seat was even higher because the angular momentum acting against the gyroascopic effect would be lower.

My idea was to use flywheels to catch the momentum so stopping is easier. Also a monowheel is not verry stable because you can't steer it. If you look at a bike you'll see that the front wheel wil turn if you angle the bike. I think this problem could also be fixed with a flywheel. This time to use it to create the "steering momentum".
@simonbolhuis44412 жыл бұрын
Perhaps there could be a box of flywheels for momentum storage; spin up a flywheel before you start driving and when braking that flywheel could be braked hard to dump its opposite momentum into the vehicle, thus counteracting the undesired spin. Pairs of flywheels on the other axes of freedom could *maybe* offer some stability there; dump some momentum to effect the desired reaction in a pinch. Maybe go crazy with not just a fixed flywheel but a set of Control Moment Gyroscopes with axes that can be turned as well, if they can be made fit? That however sounds way too bulky for a single person vehicle....

@schr4nz Жыл бұрын
Counter-intuitively, I think sitting closer to the ground might make things worse. Part of the thing that makes a bike easy to stabilise is the weight that you can shift (i.e. your body) has a larger moment arm around the pivot (i.e. where the wheels touch the ground) than the rest of the bike. The difficulty is that you do want the inner ring to be bottom weighted because otherwise you risk spinning around as nearly seen a couple of times in this video. I think what you really need is a silly heavy weight attached at the bottom of the inner ring, so close to the ground that it has barely any moment, but a relatively central riding position.

@@Enginehearth I can't find the video but I suspect that the gyroscope is acting to slowly. A bike is also different from a mono wheel in that is has active steering controls. When installing a gyro scope for stability on a mono wheel I would suggest using it for steering as well. The fly wheel is trying to keep the monowheel along a certain axis, when steering, this axis should slightly lean towards the desired steering direction. Not sure it would work but would love to see them give it a try

@@Enginehearth I suspect it didnt fail because of countering the human, but maybe because of the counter-intuitive way that steering a bike works. You cannot just lean the bicycle to the left to counter a movement to the right, actually, this will have the opposite effect. When you turn, you push your steering wheel in the opposite direction, which increases friction on the opposite side of the tire, which makes a momentum which makes the bike turn. So to turn, you first steer in the opposite direction, before the lean angle increases and you 'switch' direction (rather you go to an almost neutral steering angle). I am not sure how this would work for a monowheel though, as the steering isn't done in the same fashion.

I've had a thought on how to make it stop rolling forwards when you're stopping, but it may not be as straight forward to implement as I imagine it to be. What about adding a tilt sensor to the assembly with the seat and using it in conjunction with the electric motor to apply a backwards impulse to balance the seat assembly? This should (if my thinking is right) both help balance out the seat and stop you from flipping, AND apply a braking force to the wheel itself. This also could help with acceleration, by having it limit the throttle as the central seat assembly starts to tilt back. Also adding ballast on the bottom of the inside assembly could really help with all that.
@The-Urban-Goose9 ай бұрын

I think the standard monowheel breaking method is to just fall on your side. Actually breaking causes you do go in to a death spiral (as you discovered). You could try training wheels. Instead of on the sides like a normal kids bike just put one in front and one behind the main wheel. Once you get used to that you could do the old 'raise them up a bit' trick till you get good at it.

No thats a pretty solid intuition. I'd put a serious chunk of weight under, and slightly to the back to counteract the small frame pushing the rider forward. The bigger, and safer, monowheels usually have the rider leaning right back countering the mechanism urge to flip forward. Harder in this significantly smaller frame. But it could be replaced by a big chunk of lead just at the back of the seat.

Love it :) I've been fascinated by monowheels for a couple of decades, but haven't had the where-with-all to pursue it yet. Maybe try putting the seat down a lot to move your centre of balance, and drill holes in the top, heavy steel bracket (al la racing car design), to further reduce top weight. At the moment you're quite close to the central pivot point of the contraption, so acceleration and deceleration tries to rotate every thing around you, whilst you spin in the middle. If your weight was a lot closer to the bottom, then the accel. and decel. would have to try and lift your mass upwards around the arc of the wheel, thus providing resistance that can be translated into forward and regressive motion. I think :) It's been a mental experiment in my head for years. My only concern is that when braking, your mass would shift towards the rear a bit and I'm not sure if that would de-stabilise the Monowheel. All the best with the project.

I know this a year old video, but after reading several comments, I find it odd that I didn't notice any recommendations of a backrest of sorts. It would help keep the center portion from acting like a pendulum and maybe help stabilize the rider as well. Forward foot pegs, with landing gear wheels to help with sudden stop anti-roll, would also be a good add. Cool concept!
Thats one ingeneous and creative design considering you didn't even have a shop to build it in. Everyone is giving you advice but I don't see anyone doing it. Too much fun !
Can't help feeling if it was 3" taller inside, you'd get your head in and keep your weight central as opposed to off to the side, which might give you more control/balance - the option to shift your weight has got to be a good thing, right?
Yeah, I think your right, he needs more head room, so he needs to be Lower... the straight cross bar that the saddle is on needs to come down to another support wheel, which would lower the whole set-ups centre of gravity, and also give more head room. Then he can lean more for better balance. Also, rather than going pure monowheel with his feet up, he could get some heelys shoes, the ones with the hidden wheels in the heels, and just keep his feet down for stability.
being taller and wider would likely help quite a bit lol (ofcourse being too wide would mean you can't see)
I was hoping someone said this.
I guess that he can lower the seat a bit to make room.
I was about to comment this
I feel that if you'd just add a little swaying part at the front with a single smaller wheel, functioning as stabilizer, foot rest, and steering, it would actually work decently well
So a modernised penny farthing
It would . . . and also stop being a monocycle.
I would add a pendulum and training wheels
Yeah you could also improve it by adding a frame and making the wheels the same size then adding some handlebars
or maybe like for skying, the thing it could help
I don't know much about engineering nor mechanics, but I feel like using the same system that stabilises a hover board or segway platform for this mono wheel would help a lot. Also, I think incorporating weight to the front would help.
Ever notice that no rocket scientist ever flew in any rocket they designed? They always find some balls out hero types for the testing.
You need to add a foot rest that is out in front of the mono wheel plus a little more weight in the front. Part of the problem you're having is that there isn't enough weight in the front. On top of that without a solid foot rest it's hard for your body to balance and control. I'd also recommend making the rollers out of a different material, but I think you know that.
would also say sitting lower, and a bit more center wouldnt hurt either
if you had more weight on the front it would be unbalanced when slowing down so maybe a counter weight in the centre?
I’d also recommend lowering your center of gravity by lowering the seat. This will inherently increase your stability.
Also grease of some kind of lube on the rollers.
It’s the mounting point for his seat. Needs to come forward more, which would require a bigger wheel
While the goal of the monowheel is to be contained within the monowheel, yours is a bit... small... but since you've got it build, a step by step suggestion as a jumping off point for mark 2! Step 1. Extend the foot rests in front of the monowheel with a comfortably wide stance. The forward weight will reduce forward rise from acceleration. Adjust weight accordingly (but do not completely negate rise.) The forward, wide stance will allow you far greater balance, and thus turning. Step 2. Add a wheel on the foot rests, but with high resistance, potentially a breaking system. This can be a single wheel in the center or, more preferrably, two small wheels on the outer edge for stable and safe breaking. These wheels will not touch during actual driving, maintaining a "monowheel" status. Step 3: HELMET. You got a light bonk in the video, but that could have been quite a bit worse. Invest in a full face DOT helmet if you're going to leave massive bolts at temple level. Are extra wheels for breaking/safety cheating? Do the wheels on a jet make it any less of a jet? If you are willing to rebuild the inner body... lower the bottom rail for a more "cruiser" feel. Lower center of gravity should help with canting forward and back to offer more head clearance. You got brained because you couldn't shift weight to the other side with no foot brace and the risk of a lobotomy by ducking through the tiny gap.
yes
Sounds like working smarter and safer when finished
4. Develope a feedback loop with a gyro that varies throttle/braking to control the internal mass. A larger wheel with the person close to the bottom will give more authority to resist internal rotation.
I agree with this except DOT is the worst helmet standard. Never set that as your baseline, it’s essentially like taping a popcorn bowl to your head and calling it safe. There are now like three different helmet standards of increasing difficulty to obtain past DOT.
This Sounds like Chat GPT sugesstions
Coming in late, but I feel like your ultimate stability fix would be a pair of pneumatic skids you control by sticking your feet into them, like boots, or ski straps. They could support the monowheel for balance in all directions, and you just change their angle and level by moving them with your feet.
Now, you only need a General Grevious cosplay

@@nana-nr6xr not really an invention lol, also would be a safety risk. He does need to keep balanced centrally though, but the wheel is a bit too small

Honestly the South Park design really is the best engineered design for this kind of bike, you really should have just followed those plans.
Best South Park episode. Obviously you are missing the 'rear' stabilizer.
Here are a few tips to improve on the design: 1. Increase the weight at the bottom. You want a low center of mass so you stop rotating inside the wheel as easily. 2. The ratio from the immer wheel to the outer wheel is way too low. Put on a bigger wheel, which will prevent you further from rotating inside of the wheel, due to the higher energy required from the motor to spin the outer wheel but it will also increase your top speed. 3. Put some foot pegs further out. You are way too cramped in there and it will also make you spin less inside the wheel, due to you being stretched out further.
I really should read the comments before writing the same thing someone else says.
also could add those little helper wheels
4. Add an automatic gyroscopic balance systems to keep it from falling to the side. I've seen videos where people built monowheels that self-balance and basically stand on their own.
He should add a back rest so he could have more points of contact
I was thinking a support arm under the seat to bear the weight of the rider and have another point of connection to the wheel
"Im not basing my desing of the south park one" *We were on the verge of greatness, we were this close.
I think this is an awsome little thing. In its current state it's cool, but lacking, and both I an many people would like to see this functioning to its full potential. I think one good idea would be to add balast to where you want it to balance, as well as adding balasts that extend out to create a more triangulated center of mass to keep it more balanced. Another thing you could do is to provide more clearance to the head by re-shaping the upper brace to fit the contour of the drive wheel, as well as make the foot rests wider and move the seat back to create a more comfortable position. One more thing would be to fit inner tubes with real tires to create a more comfortable ride, and to add brakes (just simple cable-driven brakes would do), that way you wouldn't have to use your feet to stop. There's much more you could do, but these are the easiest improvements I could think of that wouldn't require building an entirely new model. I hope you see this comment and consider it, I would really like to see this bike updated!
It’s kinda a lot to think about but you need to add some kind of gyroscope to sort out balancing plus the wheel is fixed where as others move and sway to allow for turning and balance
That looks like a fun build. I have seen many of these mono wheels and they all have one thing in common, the seat is very low for better stabilization. Your seat may be too high and is the reason you are having trouble balancing the monowheel while driving. Lower the seat, and you should have much better control.
the balance Issue results from the simple fact, thast the bike ist far too small, and so he has to lean out to one side constantly. the center of mass is not the problem, actually it would be better, if the seat was even higher because the angular momentum acting against the gyroascopic effect would be lower.
@@cnschu Look at other videos of people riding these. They all have a common factor... The seat is lower. In Physics, this means lowering the center of gravity.
@@cnschu That would be true if the point where the wheel tips over is himself (aka the center of mass) but that would only happen in the air or in space, here the wheel is bound to tip over in the point where it makes contact to the ground so bringing the center of mass closer to that point makes it so that the gyroscopic effect can help stabilize it more effectively because it sort of has more leverage so to speak
It's amazing ! Well done ! You could maybe increase the wheel diameter and lower the centre of mass to make it easier to handle ?
Yup, he can't even hold his head up straight and he's forced to sit leaning to one side.
I think making a penta shaped frame will lower his mass and increase head room allowing for a lower center of gravity and keeping the weight distribution centered. Overall looks like a very fun project though.
@@SurelyLightFoot yes, that would, however it would create new joints and therefore potential points of failure.
A counterweight hung under the seat would help lower the center of mass increasing the stability. One possible option is to use sealed lead acid batteries as the counterweight with a DC to DC charger suitable for the task.
Mr. Garrison made this back in the early oughts.
This guy is gonna be the adventer of what all of us will be driving soon
I admit after watching a SouthPark episode with one of these before, I was curious what this guy's seat looked like. 😅
Just went down the rabbit hole of seeing how other people have approached monowheels - and I was surprised that seemingly nobody has come up with a better answer to steer and/or stop these things or make them even a little bit more stable. Seems like a fun project though - can't wait to see where this ends up.
I think the reason most of the reason few people build monowheels is because of the "gerbiling" i.e. spinning backwards when breaking which afaik is simply a problem of the inherit physics of these vehicles. Which is a shame as they're really cool.
My idea was to use flywheels to catch the momentum so stopping is easier. Also a monowheel is not verry stable because you can't steer it. If you look at a bike you'll see that the front wheel wil turn if you angle the bike. I think this problem could also be fixed with a flywheel. This time to use it to create the "steering momentum".
Perhaps there could be a box of flywheels for momentum storage; spin up a flywheel before you start driving and when braking that flywheel could be braked hard to dump its opposite momentum into the vehicle, thus counteracting the undesired spin. Pairs of flywheels on the other axes of freedom could *maybe* offer some stability there; dump some momentum to effect the desired reaction in a pinch. Maybe go crazy with not just a fixed flywheel but a set of Control Moment Gyroscopes with axes that can be turned as well, if they can be made fit? That however sounds way too bulky for a single person vehicle....
Why aren't PID loops used for breaking? The same way drones stay leveled at the horizon.

Would love to see an updated model. Perhaps with foot pedals and 4 extra skate wheels in front and back. Sort of like training wheels, but help to stabilize the rig. Incorporating a gyro would be ideal. It looks like your shoes won't last a week if you keep using them as brakes. Cool concept, though. Very futuristic.
As soon as I heard him say "Oh look, the PLA's coming off" I immediately went: "You used PLA for a wheel for a machine???"
*Girlfriend sees the Hello Kitty bike on the wall* Girlfriend: "Oh it's your daughter's bike? How cute!" Sam: "Nah it's mine. I didn't have the heart to cut it so i kept it because of sentimental value." Girlfriend: 👁👄👁
Friendly safety note: grinding galvanized steel is just as bad as welding it. You were probably fine, being outside and not doing much of it. But I made that mistake once and ended up with some nasty metal fume fever.
I got some surprising (to me) symptoms and all I did was cut galvanized pipe, drill a couple small holes, and bend the pipe with a pipe bender. I did it outdoors and had been holding the pipe with gloveless hands and I think a lot of my exposure was due to skin contact with pipe
@@julianbrelsford normaly you shoulnd have aby problems as long as you dont breathe it in .... Skin contact should not do anything
Another step closer to becoming The Master of Faster; he who rules the duels; the one and only King of Turbo Duels.
I feel like if the mono wheel's entire assembly could be 5% bigger, it could improve. So you can install something for your back to lean on, or install like a bucket seat. And the wheel itself to be either wider or accommodate an actual tire for ride comfort.
just a super tiny note here: when cutting with the sawz all, make sure the metal foot is pressed firmly against the thing your cutting. this helps move the machine make up again and the weight of the unit helps move it back up again, you shouldn't have to apply much force at all just hold it in place as it does the work
what is it with americans and using brand names for everything? it's a reciprocating saw, Sawzall is just one type of many
Exactly! I hate that especially for “Sheetrock”!
Things that I think would improve stability: 1. Larger diameter with you sitting lower to the ground relative to the total diameter 2. Actual tires that are inflatable on the outside 3. Wider/fatter tires with a curved profile (ala bicycle/motorbike)
Counter-intuitively, I think sitting closer to the ground might make things worse. Part of the thing that makes a bike easy to stabilise is the weight that you can shift (i.e. your body) has a larger moment arm around the pivot (i.e. where the wheels touch the ground) than the rest of the bike. The difficulty is that you do want the inner ring to be bottom weighted because otherwise you risk spinning around as nearly seen a couple of times in this video. I think what you really need is a silly heavy weight attached at the bottom of the inner ring, so close to the ground that it has barely any moment, but a relatively central riding position.
@@Chaddledee Best fix he can easily apply is fill the metal pipe with weight to increase angular momentum and thus stability. As for braking you would need either your feet or some sort of assist wheels that come down when you brake. Not an ideal solution but there is a reason why monowheels are only built in some curious hobbyists sheds
All of this and how about a board computer that guarantees your horizontal position all the time?
"It needs to be big enough and strong enough to fit me in." Our mothers might know a thing or two about this.
Back in my day we called these the "It."
Use the shoes with the wheels on the heels. I don’t remember what they are called. But they would be great for this because the wheels would just roll along like training wheels for a bike, it keeps it stable while not scraping anything.
it is wheelies shoes, though with how the wheel doesn't have stabilizer and he is not used to it yet, his feets are basically act as brake at this point.
@@shikniwho7215 ugh. No. They are heelys
Nice work. I think it would be easier to ride if you added a lot of ballast low down under your seat. That would stop it tipping forward when you brake, and probably make it easier to stay upright too. I hope you make a part 2 of this video with a few tweaks to the design because this is so close to being *almost* a practical vehicle ;)
It would still be unstable, but having a lower center of gravity would allow for *some* acceleration without it wanting to rotate the driver along with the wheel when the brakes are applied.
Try training wheels!
Would help but not much. It needs a powerful gyro attached to the seat. Vertical axis, 2 flywheels rotating in opposite directions.Only this would make it possible to properly brake, accelarate and move upheel
hmm, perhaps you should have based it on the South Park design. That one worked so well it was going to put the airlines out of business.....though you would have to deal with some....shall we say, soreness after riding it
E-bikes can only get exciting if they go faster than 30mph and/or if you get creative with the designs like this. For example, reversing the wheel on the Hello Kitty bike to create the ultimate ball masher. Seeing the end result at the end of this video, this design really just looks like a scooter you sit on, inside of a ring. I might redesign this simply using a much bigger ring, and then simply attach a stand-up e-scooter inside the ring.
That thing is surprisingly nippy for only being powered by a chinese scooter motor. An inbuilt gyroscope (as hinted to in the design of the South Park monowheels) would probably work wonders for making it ridable by reducing the number of axis you have to worry about. Great stuff!
That's how the segeway type ones do it.
"chinese scooter motor" Like there's any other kind 😂
@@b5a5m5 yeah even QS motors are "Chinese motors"
Should not be needed (gyro) - if small ones can ride it, so could Sam with a little training. An old vid of this driven by 4-5 year old kid: kzhead.info/sun/eqppotWknpaXe4U/bejne.html 🤓 Edit: The South Park 'IT' bike - epic 👍😂🤣
Every single scooter motor is a chinese scooter motor mate
Considering the fact that you broke the first trampoline wheel, there’s no excuse for not finding a wheel with the proper diameter to fit yourself inside… Literally would only have had to lengthen the inside stabilizer rods.
That's really cool! Perhaps you can get it more stable at lower speeds when you add a fly wheel and lower the balance point? You could have your feet outside the wheel if the fly wheel is behind you, to get the horizontal balance right. And please don't kill yourself with electric tools. Use a clamp if you drill parts that weight more than a bullet. ^^
Man, when you went sideways i thought those long bolts were going straight to your temple
id love to see a part two! definitely curious to see if lowering the seat bar, replacing the PLA bearings, and other improvements could make it a more stable ride. also want to see you order some heelies for when you use your legs to stabilize.
Use a flywheel with a controller for stabilization by countering the unwanted angular momentum by spinning up the flywheel. No idea how practical it would be, how difficult to implement and where it's limit would be of what "leaning" angle it would be able to recover But maybe give it a try. Gyroscopes and angular Momentum will always be fun :)
I cant find the video, but there was a video from a Japanese show where they put masters and technology to compete. In one episode they has a master bike builder and a technology team with the challenge of gliding with a bicycle on a narrow path without hands. The technology team put a controlled flywheel on the back of their bike but the implementation failed since the rider also instinctively corrected their balance fighting the flywheel.
Ah I found it! its a show called "Supreme Skills! 2016x11 The Super-stable Bicycle".
@@Enginehearth I can't find the video but I suspect that the gyroscope is acting to slowly. A bike is also different from a mono wheel in that is has active steering controls. When installing a gyro scope for stability on a mono wheel I would suggest using it for steering as well. The fly wheel is trying to keep the monowheel along a certain axis, when steering, this axis should slightly lean towards the desired steering direction. Not sure it would work but would love to see them give it a try
First thing he needs is a footrest.
@@Enginehearth I suspect it didnt fail because of countering the human, but maybe because of the counter-intuitive way that steering a bike works. You cannot just lean the bicycle to the left to counter a movement to the right, actually, this will have the opposite effect. When you turn, you push your steering wheel in the opposite direction, which increases friction on the opposite side of the tire, which makes a momentum which makes the bike turn. So to turn, you first steer in the opposite direction, before the lean angle increases and you 'switch' direction (rather you go to an almost neutral steering angle). I am not sure how this would work for a monowheel though, as the steering isn't done in the same fashion.
You need wheelie shoes like the kids back in the early 00s were wearing. Skate wheel in the heel for stability, and maybe some cemented on tire rubber in the toe area for the brakes / steering.
Nice! Heelys for stabilizing, and a back support on the seat to keep it level. Maybe some skid protection and helmet..!
putting a little anti-"wheely" bar on the back might be good. spring loaded or something with a small wheel itself to roll about. also put on some heelys lol
... and a "eileehw" bar on the front - that's "wheelie" spelled backwards, as it would be to do the opposite thing.
A monowheel with an extra wheel isn't a monawheel my friend
@@DownhillAllTheWay I think technically they’re called “stoppies” but I like “seileehw” more.
@@simonbolhuis4441 what about an anti roll skid plate?
I was gonna mention heelies. Glad I wasn't the only one.
This is very exciting. If you do a version 2, take advantage of your friend's shop and turn some wheels out of delrin or something for the idlers. Consider using contact cement for the tires. If it's in your budget, a wheel large enough that you don't have to duck under while riding might work better. Fly safe!
A V frame with stabilisers attached to under the seat to make contact with the road, an added extension to the frame to allow legs to be extended, now we're talking.
I've had a thought on how to make it stop rolling forwards when you're stopping, but it may not be as straight forward to implement as I imagine it to be. What about adding a tilt sensor to the assembly with the seat and using it in conjunction with the electric motor to apply a backwards impulse to balance the seat assembly? This should (if my thinking is right) both help balance out the seat and stop you from flipping, AND apply a braking force to the wheel itself. This also could help with acceleration, by having it limit the throttle as the central seat assembly starts to tilt back. Also adding ballast on the bottom of the inside assembly could really help with all that.
suggestions: instead of just rolling it forward, you may want a controller so the motor tries to keep interior section upright, like one of those hoverboards. And then you may want a wider wheel so side-to-side balancing is easier.
Instead of a controller, you’d want to use a gyroscope so that you can adjust for speed independently of the system. If not, then the process of braking quickly may break the system keep you up causing you to flip over.
When your monowheel smashed into your head, I laughed and poured water straight down my trachea and started choking, prompting my girlfriend to try and run and save me where she ran into a chair leg and fell down on the ground. Your machine almost claimed 3 lives so far!
Your story was solid until you said you had a girlfriend

Never seen you or this channel before but you got me to sub in 33 seconds :o
you need peddles to rest your feet! But well done lads that's utterly brilliant! Thanks for your hard work.
Awesome!
Dich hätte ich hier nicht erwartet 😹
Das hat mich direkt an „it“, mr garrisons Gefährt, aus southpark erinnert. - was ist ‚es‘? und wann kann man ‚es‘ kaufen? :D
I love how falling off also smashes your goddamn skull in, what a nifty safety feature.
Can't feel embarassed when you are braindead! :D
For breaking I suggest one or two curled up 'foots' infront of the monowheel. This way you don't topple over when you want to deeccallerate
Use a self balancing electric unicycle as the engine. The Mten3 would be perfect
EUC gang lol
or maybe an onewheel they are rather cheap for what they are
Or just ride an EUC instead. :D
@@garnknopf155 onewheels are incredibly expensive for what they are compared to EUCs
You’re so underrated
Holy Broly this looks awesome... it only needs some pedals to place the feet and a brake and it's good to go
Southpark got the design almost 100% exact on its first try
0:35 Cant wait for someone to actually make truly drivable, visually a close copy of this thing! With electronically assisted gyro for stability, drive by wire assisted steering. Like any car, sit and drive with ease! That *will* be the coolest freaking thing in history of the universe!
7:33 chop those long bolt-ends off to prevent personal injury when you fall off !! they are right at your eye-level . well done Sam thanks for sharing
This was my thought too! So close to impaling himself and it made me nervous as all get out. Even just reversing the bolts the other way if you have a tendency to only look out one side of the wheel.
Very funny and cool! :D I was totally laughingf my ass off when you took the Monowheel out into the public. So funny! xD
It would’ve been easier to ride if you had a larger frame for the wheel, and also a wider tire for more room to sit and also just for better balance. But I’m not an engineer so… yeah
I think the standard monowheel breaking method is to just fall on your side. Actually breaking causes you do go in to a death spiral (as you discovered). You could try training wheels. Instead of on the sides like a normal kids bike just put one in front and one behind the main wheel. Once you get used to that you could do the old 'raise them up a bit' trick till you get good at it.
Or maybe by programming the motor to slowly pick up speed and not stopping all the way the moment you brake and therefore get more stability when driving?
Within the mind's workshop, a vision takes its stand, Sam Bark crafts ideas with skillful hand. An ebike monowheel, both novel and grand, Imagination turned real, a testament so unplanned.
Lower the center of gravity by lowering the seating point. OR for the current build add a weight under the seat that tracks and also has foot pegs out front, use that swingset double seat design to swing the weight when braking using your body pulling the handlebars while pushing with your feet to move the weight beneath you while engaging a braking. (where all the dialing will need to be.)
People on the side walk be like: Oh sam is here again and his contraptions
It works shockingly well! I wouldn’t have expected it to be as easy to control. I think that if you were to add some weight below the seat it might help with the problem of the frame wanting to spin around when letting off the throttle. Still, that’s only my speculation. Nice build!
No thats a pretty solid intuition. I'd put a serious chunk of weight under, and slightly to the back to counteract the small frame pushing the rider forward. The bigger, and safer, monowheels usually have the rider leaning right back countering the mechanism urge to flip forward. Harder in this significantly smaller frame. But it could be replaced by a big chunk of lead just at the back of the seat.
This project perfectly exemplifies how, mostly what we 3D print is the connector-y bits!
"still better than what we have to go through at the air port"
I honestly thought this would be Tom's project first, seems like such a Tom thing to do - You did a great job tho!
I would like Colin to have a go at it. however he might replace the engine for a yet engine.
This is really interesting. A tip could be to make the wheel a lot bigger so that it supports and balances you a lot more, it also might be a good idea to add more structure as well. Wonderful work I Would love to see these beautiful things in the future.💗💗💫💫
I feel that increading tre diameter of the wheel it self needs a boost, for comfort reasons. Also widen the wheel it self. Make it a "fat" wheel, like the wide wheels of a bike. Makes it easier to balence and more stable when dealing with terrain.
heelies + monowheel = superior transportation
Love it :) I've been fascinated by monowheels for a couple of decades, but haven't had the where-with-all to pursue it yet. Maybe try putting the seat down a lot to move your centre of balance, and drill holes in the top, heavy steel bracket (al la racing car design), to further reduce top weight. At the moment you're quite close to the central pivot point of the contraption, so acceleration and deceleration tries to rotate every thing around you, whilst you spin in the middle. If your weight was a lot closer to the bottom, then the accel. and decel. would have to try and lift your mass upwards around the arc of the wheel, thus providing resistance that can be translated into forward and regressive motion. I think :) It's been a mental experiment in my head for years. My only concern is that when braking, your mass would shift towards the rear a bit and I'm not sure if that would de-stabilise the Monowheel. All the best with the project.
Could you add more mass low down so that the part you sit on wants to stay planted more? Like a keel on a ship. This would also lower your cg and I think help with balance as well.
Yep, the lower you can get the CG, the less prone these are to 'roll over', either when accelerating or braking. Though it's always going to be a concern
what about small and close mounted stabilsers to the inner frame fore and aft to prevent roll of the inner cage, could have them on a suspension which allows for left right steering but has zero forward or backwards motion, or slightly offset at the rear with a higher angle for that fun wheelie feeling.
WHERE IS YOUR HELMET? OH THERE IT IS!
As an expert in nothing, the only thing I allow myself to say is that's a gorgeous build. (Or maybe a wider surface wheel can help) And good luck with practising that.
Even though other people have made mono wheels in the past, you built one with your own parts and somewhat succeeded. Maybe more weight on the bottom support could lower the point of stability ( I have no idea, just a thought ). Either way, good show. You get high points for trying. Good luck.
I was also thinking he should basically be sitting on the bottom of the ring with his feet up in front of him, would allow his weight to have more influence over the motion
You're not the first. The gyroscopic effect is how this works, an inventor of the 1930's did this exact thing but put a simple 2 stroke motor on and it was actually a huge success, at speed. "Upon braking, the machination would plummet the driver forward with the momentum as the single wheel did not encourage loss of velocity."
really hope we'll get to see you perfect this design one day.
South Park already did.
It might be a good idea to mount a counterweight under the seat. That would be a good place to add a large battery pack, and any other equipment you need, as well as a large block of steel or lead. I've seen some monowheels that used a petrol engine, and they mounted them at the bottom of the frame as a counterweight.
This guy!
With an added weight in the center bottom, I feel like you could up the stability considerably while also keeping it from reacting so heavily to accelerating
