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 ❤

I ride a lot of different bikes, and I feel like a wider wheel/tread would go a long way to making the thing more stable, in addition to the positioning changes others have mentioned. But that’s an awesome start! I’m digging this 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!

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.

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?

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.

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.

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

And bronchitis

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.

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.

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.

Maybe instead of putting your feet up you could wear roller blades instead? Brilliant build by all means

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.

This is fantastic :) I built a monowheel a few years ago, although mine was noisy and gas-powered with chains to gear it down. I much prefer your powertrain. I was nodding as you were saying you can’t let off when you start to panic haha. Mine was very heavy (around 100kg), I wonder if that made it easier to ride.

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.)

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.

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.

"Im not basing my desing of the south park one" *We were on the verge of greatness, we were this close.

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.

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!

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.

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....

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.

Best South Park episode. Obviously you are missing the 'rear' stabilizer.

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.

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.

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.

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!

Everything about your bike is counterintuitive, but I love the idea. :D

I was gonna mention heelies. Glad I wasn't the only one.

I was going to suggest some Heelys or skates. Perhaps a weight to the rear to prevent tipping?

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???"

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.

@griffin8er845

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.

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.

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

The whole pitching forward issue when you panic would be resolved potentially if the wheel powering it only made contact with the large outer wheel when you want to accelerate.

I love how falling off also smashes your goddamn skull in, what a nifty safety feature.

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.

This project perfectly exemplifies how, mostly what we 3D print is the connector-y bits!

I feel like itd be more controllable with a wider contact patch on the ground, but thats just with mr looking at it from here.

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!

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!

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.

Imagine going down a steep slope sitting in a skinny road bike tire and trying to stop in 30, 40, 50, 60, 70 meters. Too late, you just went off the cliff.

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.

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

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.

Install a V shaped metal fixture for the pegs that has one small training wheel on each end of the “-V-” then apply pressure with your legs to achieve 3 wheel stability. Just a thought. 🤔

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!

@shayneoneill1506

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.

Monorails are really hard to ride.....and really REALLY dangerous. YOU CAN'T STOP. The inertia just make the whole wheel keep rolling with you and everything in it, right into whatever obstacle you are trying to avoid. Next project please :D

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

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.💗💗💫💫

bigger diameter, use thicker metal so the tread is thicker for the wheel and then maybe find a way to put an inner tube in, some suspension, foot pegs, maybe add a simple brake/disc *may as well make the middle a bike frame or use like a mini moto frame and essentially make the round tube more of a rim

Nice job! I wonder how it would look like with gyroscope-based movement (tilt forward - move forward)

Use a self balancing electric unicycle as the engine. The Mten3 would be perfect

Needs more mass at the bottom to keep you stable without turning inside the wheel. If it was heavy and big enough to keep your feet up, you could eliminate a lot of the minor trips from dragging your feet across the ground while getting better balance.

Very funny and cool! :D I was totally laughingf my ass off when you took the Monowheel out into the public. So funny! xD

I would like Colin to have a go at it. however he might replace the engine for a yet engine.

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.

@qumefox

2 жыл бұрын

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

If you ever are intending to revisit this project at all in the future... might I offer a suggestion for inspiration? Star Wars had an interesting approach to it with General Grievous' legged bike. Where you basically take the engine from the bike and shove it in the sidecar, so you're sitting on one side of the wheel, but can still see _under_ the inside of the rim and out the other side. Oh, and kickstand leg. It's also safer, since you can add a counterweight system so if it loses balance, you can knock it on the side that DOESN'T have the driver. And even if it falls on the side of the driver, rollbar edges and the clearance in between the drive ring and the outer rung ensure their helmet isn't hitting too much metal and pinning the driver down. Perhaps if it's possible to do just that; take the seat of a motorbike and shift it to the side, so you can make the engine and gyroscopic system as it needs to be. Just keep enough out of the center so you can see over the engine and under the wheel, and wear a helmet.

@Skorpeonismyrealname

Yes, it's likely to be far more advanced, even before taking gyroscopic balancing into account, but perhaps with a bit of luck a smaller scale proof of concept will go far.

"I think I'm finally getting the hang of it." *Falls and bonks head*

You’re so underrated

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.

@vegassoderstrom

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?

This guy is gonna be the adventer of what all of us will be driving soon

Oh you can definitely weld on galvanized stuff it just makes things look and taste funny for awhile im sure thats completely harmless tho it goes away after a bit

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

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.

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.

Honestly the South Park design really is the best engineered design for this kind of bike, you really should have just followed those plans.
