I Loved this this project, trying to get a random idea to work is classic furze but can we make a MK2 let me hear your thoughts. Work on the garage will contine in January. Thanks for watching and hope you enjoy the merch.
As soon as I saw the video title I thought to myself this is a Furze classic. The builder of quirky bikes
With all the ebikes about using an electro magnet would up the power a lot which might provide a lot better suspension
Transbike, very 2025 Colin 🤣🤣🤣
Make like half circle support rails that keep the frames in plane. Set the support rails somewhere down low tho so you can still see the magnets on top
Bike engineer here ; hit me up if you need any help with the V2, I'm sure we can work something out ! The scariest part is manufacturing but it seems like you've got this figured out already
Collin is one of the few creators keeping the spirit of old RUclips alive
Just a matter of time before RUclips ruins it for him as well. That's all they seem to be able to do these days.
I don't think they can. Collin been doing his videos in the same style before even I was born. And we Collin fans will always watch his videos.
colin >>>>>>>>> mr beast
YES! Couldn’t have said it any better!
@Batman2005-o6t RUclips likes to take money away, or just shut down channels for no reason these days. Him and Mr. Beast are probably fairly safe, but who knows.
Anyone else think it's fascinating that Colin has everything one would need to build his own bicycle basically from scratch, but had to borrow a neighbor's bathroom scale?!?
Obviously his only vanity is for his projects. That or her tore it apart for a project.
😂 men
⚖️ are a stress factor, I don't own one either because we never agree, I mean why is it telling me that double bacon quarter pounder with extra cheese and side of chili cheese fries is making me feel overweight. 🤪
Hahahahaha!
He clearly broke his own set, which was how he knew to go easy on his neighbours set
I think the single coolest thing that Colin has ever done is asked local bands to feature their music in his videos. It’s such a great opportunity to hear new songs by different artists that you would never come across normally in the algorithms I just think it’s really cool.
Very good point 🤝
I noticed the soundtrack but didn't know the details about the local bands. Thank you for telling 👍
Yea, he's always had good music in his vids
I'm in a band play my songs
Yeah I loved the marionette song used in the build montage. He auditions some nice tunes every video.
Yeah I really loved the last 2 songs.
4 super strong neodymium magnets trying clamp together with 250kg of force stacked right in front of your jewels sounds like absolute madness
The fun and adventurous kind, or the dangerous kind?
Fitness equipment - but with magnets instead of weights.....?
To quote Run DMC: "It's Trricky"
So it wasn't just me that thought of the musical "nutcracker"
I’m so glad he changed the magnet location. Two 200kg magnets hanging below the scrotum made me feel sick.
mark I: ball smasher
@DefenestratedDevices the smash that keeps on smashing. Balls would just be permanently embedded between those magnets.
I suppose he could use stabilizer pieces (for keeping it all aligned) between the bendy parts and the magnets instead of right at the center of the magnets to keep it lookin' slick.
But yes, the magnet position is, even in his 2nd iteration, something I'd work on for the sake of future generations.
Yes, that would've definitely made his voice go up a few octaves
@TheTruthKiwi Yup! The bike wouldn't have been the only thing that transitioned in the video...
Having worked with strong magnets, watching Colin handle these bone crushers is more stressful than the spinny blade extravaganza he treated us to before
I was just waiting for him to crush a finger. Magnets that powerful are s c a r y
Had the same thought , I’m actually kind of shocked he didn’t severely injure himself.
I'm amazed you can courier magnets! Can picture the box fixed to the van.
They are scary things for sure. And a bit of a liability 😆
Don't worry. He's wearing his safety tie.
On behalf of the Wooden Society, we would like to thank you for making us aware of the dangers of unfelt and unseen forces. BTW: Since it's Christmas you should name that test bike "The Nut Cracker". It needs a caution sticker. Do not ride while wearing short shorts.
Thank you. I wonder if we'll ever get past this Big Engineering conspiracy, that metal comes from ores from the ground? We know everything's wood, and metal is fake.
Do not ride with cards in your pants pockets containing magnetic stripes.
'where's the saddle?' said THIS no-wun
'yes, yes it does doesn't it...'
you mean do not ride after 45 xD xD xD
You've got some real wild thoughts on where certain body parts might hang to, good for you I guess
realistically I'd be more actually concerned with it pinching my inner thigh.
Riding down the street, all the bumps absorbed by the power of magnets on a unique bicycle built by your own two hands, erasing every credit card you ride past. Bliss.
Nothing was absorbed because bicycle doesn't have any shock absorber only useless magnetic spring.
Bonus: steals everyone's loose change from their pockets when you ride past.
Sounds like a special bike you'd unlock if Rockstar ever makes a Bully 2.
And clear all their credit card magnetic stripes !
Omni-directional magnet bike colab incoming!
i had this idea but dangling this magnet in front of my bike to pick up any loose metal to stop me from getting flats
Are coins magnetic?
Thanks for using “I’m a Marionette”, Colin! Really appreciate it - and great vid!! 😃
Beautiful song! ❤
I can't find it on your channel, please upload it, it's so good
hey if that's your song i hope you understand the pathology /psychology behind what is going on cause it's a nice song but holy moly...
Can't find it anywhere. Lovely song. Where can we listen?
beautiful song, never heard of you before, but i've added you on my spotify
I suspect Colin is choosing projects based on whether or not he can use a tube notcher
tube notcher for the nut-crusher,... be STILL my beating heart
I couldn't help but think, Tube Notcher! when it was appearing in this video. I concur.
I know I am after he advised us to go out and get one.
Watch Project Farm on the way and open your wallet for the goodness of tools.
Everything is a nail when you've bought a very expensive hammer
Put the magnets inside a clear acrylic tube so that the frame doesn't twist
Also the clear acrylic tube acts as a damper like a shock absorber or airbag.
Trusting PLA or even ABS from a 3d printer to hold back the force of these magnets, THAT CLOSE to your nuts... You're a madman, mate.
You thought he was sane before and this is what tipped the scale?
They're stuck to the steel. They're trying to repeal.
It doesn't even need the safety tie
@Shocker99 Asuming he wears a safty tie down there?
Nut sure thats the right kind of protection. ;p
( ^ genuine typo but it fits so im not gonna change it. ^^)
...
On the other hand anyone who sees a john thomas with a tiny tie might think twice about what they were up to. ^^'
@Shocker99 You can see the plastic breaking near the end a 24:19. Have you ever played with magnets? When you try to push repelling sides together they want to quickly spin around and attract each other again.
A thick piece of ABS with a metal plate on the flat bits would hold up just fine.
25:03 that’s the exact reason I clicked the video
Yuuuuup
Wait till he tries to use a bike lock on this
Same
Same 😂😂
Same
What about adding magnetic damping? Basically like a shock absorber. You could take advantage of Lenz’s law: use a copper tube with a magnet moving inside it - the tube mounted to one side of the pivot, the magnet to the other, working like a piston in a cylinder. You could place this where the wire currently sits.
As the magnet moves through the tube, eddy currents create a resistive force that increases with speed, giving you a smooth, velocity-dependent damping effect.
That way you’d have magnetic springs and a magnetic damper working together.
I'm afraid this will never be strong enough for a grown man. In addition, you'll have the same resistance when "unpressing" unless you do it very slowly
@Dysonsfear771 unless you use an electromagnetic with a microcontroller that switches it off to "unpress"
@Dysonsfear771 @MikeHunt420 You want resistance going in both directions, damping and rebound.
@catsup1308 in that case you can adjust the current on the rebound
@Dysonsfear771 you would normally want damping also in rebound. Also I think a sufficiently strong magent could provide good dampening. Since the bike currently does have basically no dampening at all I think it would be an improvement anyways
A center shaft will definitely stablize it a lot. If you don't want that, either make the frame around pivot wider, or make the pivot bigger in diameter. Can't wait for the next version.
14:35 how my parents talked about me during puberty lol
🔥🤣🔥 Giggity!
comment of the year 😂
Pfft 😂
😂
😂😂😂
This is fake, you can see the exact moment the camera pans away and he installs the alien technology.
Thanks Tom
@TheDavidÓscarRomero A comment from Tom who is also an alien
@spacefightertzzof course he is, how else would he know?
@TheDavidÓscarRomero came here to comment these exact words lmao
Your confusing this with whistling diesel channel aka cgi hind and headquarters.
13:10 Absolute nutbuster
Just what i was thinking
Save money on gas and get a nutsectamy at the same time
Yep I winced when I saw that set up.
Absolutely do not wear short shorts and go commando on a hot day while riding this
@ytchrogoit reminds me of getting my sack chewed up on the tire missing a jump once 😂
16:56 The 'Spring Bicycle' throwing shade at you is next level funny. 😆
I appreciate Colin NOT making this a two-part video, while simultaneously considering making a part 2 video for Magnet Bike MK3. You're dedication is unbelievable!
PERFECT! 😂
I think the sole reason for this must be the dedication to an envisaged thumbnail
You are dedication!
@daniel.watchingindeed!
Call that bike @ 13:04 “The Ball smasher 2000” 😂😂😂
Thoughts exactly😂
Colin transformed a womens bike into a mans bike, and the bike might transform colin later from a man to a woman xD
My eyes are watering!
10mm gap 😂
i was thinking the same thing
Colin here casually designing and building an ENTIRE bike as a quick step to try magnetic suspension!
In fairness the basic form of a bike is pretty simple and also his design philosophy with it was non existent and happened to create an obviously awful suspension dynamics
@frozenwindow407 but were you entertained?
@Estop117 how is that relevant to whether building a bike is impressive or not?
@Heroo01it's not really related. I know I was impressed and entertained. At the end of the day, I think this was his goal.
@23:05 give a thumbs up for the camera man running along Colin 😂
Wood magnets. That’s what you need to invent, Colin. Wood. Magnets.
Termites?
A wooden gun?
(Hopefully someone will get this reference)
Im pretty sure that woodn't work...
The wooden society would approve of this
"I know what we are going to do today Fur(ze)b!"
20:39 most random music ever... clearly just liked the tune 😂
i love that you still put the actual thing you made on the thumbnail and not some clickbait AI bullshit. it actually makes me so happy.
Colin would never. He been at this longer than most
I know where you‘re coming from, but the fact that not using AI slop in a video is becoming something to be appreciative of is very telling, lol.
Furze meins fart in german… and that is why I want it!
Casually building a whole stainless steel bike with highlights and background music, is a major flex, that would normally be the whole theme of a RUclips video maybe even in parts 😂😆
yes!!!! that part was.... beautiful!...
NGL I had a flinching moment when I saw him hold these two iron magnets with his thumbs on the flat surfaces.
Hi Colin! Take a cue from your conical bearings and use two magnets in a V configuration opposite a cylindrical magnet (with diametrical magnetization) to align the magnetic force to the plane of rotation. The ascii art diagram would look like this looking straight down from the top: -< o-o >- There would be two planar magnets on the legs of each V and the cylindrical magnets would be oriented vertically on either side of the seat. This structure is both magnetically and physically self-centering. Put some rubber facing on the V magnets to protect them.
Beyond this, you an achieve much more optimal results if you use Halbach arrays to shape the field geometry of each magnet properly. It would be safer not to have a high field strength off-axis.
This is what I was thinking as well. The V configurations might not look quite so cool but you can force the deflection to be in line with the frame.
Well I believe I’ve learnt something thank you magnet wizards 👍🏻
damn, i wrote a similar comment after this one. i like your version a lot more 😂
This plus square braced tubing and you have a solid plan!
I like your funny words magic man.
Imagine the magnet coming loose, fliping around, and magnetically crushing your balls
If you put thick copper plates on top of the magnets you will have eddy current dampers that would be metal.
That's actually not a bad idea at all and you could even make it adjustable or variable with travel by varying the distance.
I was thinking just adding dampers which could help with alignment too, but your idea is much more in the spirit of this bike.
that may make the system a little too stiff and unresponsive though. You would likely have to do a lot of tinkering to get it right. Some kind of mechanism that could move the plates closer or further as the bike goes over obstacles might work.
This is basically a magnetic shock absorber And the flexing of the frame wouldn't matter so much.
You could also add coils to this and make dynamo out of dampers so energy don't goes only to heat
15:36 The guy who discovered magnets trying to explain them to the rest of the village
Made me laugh out loud at nearly 3am now Mrs is mad
@jakekettleborough3105😂😂
After watching the entire video the first time and coming back to that part to view it from that perspective got me cackling lmao
Saw the thumbnail but didn't completely perceive all of it, read "Magnet Suspension Bike", thought "that'd be a good project for Colin Furze", clicked it... and of course it was you!!
No way me too haha
Yep lmao
Really dig the music, especially the 4th song
12:58 the nut crasher 😂
I yelled "oh f!" when I saw that 😂
That's what I thought 😮😊😅😂
My exact thought
just in time for the holidays
@clarkeboy12345 Maybe call it the Nutcracker then?
make a plexiglass tube piston with magnets inside. You can see that there is no spring, but it keeps everything aligned like a gas piston would.
Would plexiglass hold up to the side-to-side forces? I was thinking one tube (Aluminum or Stainless Steel) inside another with the magnets on the outside but your idea keeps the proof of no hidden spring. I also wonder if electromagnets would work.
I like this idea because it would prevent foreign objects from getting stuck to the magnets. Also, the air inside would dampen the suspension.
Transparent Aluminum
Theres that synthetic quartz stuff thats clear like glass but stronger.
@jasonfabrick9308probably if it's thick enough. Maybe lexan if they make tubes out of that
I literally can't voice how incredible this channel is. Most channels would have made 12 videos about this. In one video he prototypes and then goes and builds a entirely bespoke bike.might I add out of one of the most pain in the ass materials to work with in a shop.That's crazy
Not knocking Colin at all because his tig skills are on point, but stainless is easy mode compared to titanium...
He’s brilliant
BeSPOKE, see what you did there.
A Brazilian from the "Metal Projetos" channel made this same bicycle 9 months before this video. Congratulations on translating his content into English, but I think you should give him proper credit.
If wasnt aware of this Brazilian guy, then there is no credit to give as nothing was stolen. Just because one person makes something and makes a video out of it doesnt mean other people cant make the same thing and video... it isnt copying if they werent aware of it.
@JTheraos Bem, na verdade, eu conheci o brasileiro primeiro. Já bastam os Irmãos Wright, roubar o título do Santos Drummond. O problema é o plágio. Você gostaria que eu pegasse a receita do bolo favorito da sua avó. Vendesse e nem dizer que peguei de você ficar com a fama e crédito, não é certo. A gente não impedi dele divulgar, até é bom, o nosso estava em português, o dele está em inglês. Apenas mencione "Eu me inspirei em um brasileiro" assim como "Esse bolo é meu mas a receita é da Avó do JH".
Well, actually, I met the Brazilian first. The Wright Brothers already stole Santos Drummond's title. The problem is plagiarism. Would you like me to take your grandmother's favorite cake recipe, sell it, and not even say I took it from you, so you get the fame and credit? That's not right. We don't stop him from sharing it; it's even good. Ours was in Portuguese, his is in English. Just mention "I was inspired by a Brazilian," just like "This cake is mine, but the recipe is from JH's grandmother."
I think the music at 19:05 is the chillest music ever to be put in a Colin furze video. I actually really liked it, but I’m so used to like the hard punk rock that it totally caught me off guard haha
Right? It was jarring in a good way!
Caught me so off-guard I had to double check
More likes on this and a name. I did not know i needed this today. It's been therapeutic though.
hahahah same, went to the comments to see if anyone would say anything
I was thinking the same thing. Its definitely a vibe.
Run shocks on the bottoms by each joint to dampen then porposing and make the joints out of thicker materials 25:32
Also maybe some triangulation support to the side to help center the side to side forces.
Yeah something along these lines is the most practical way to do it and you could have it bottom out with a bump stop or thick coil spring right before the magnet's max travel so they don't get destroyed.
Kinda defeats the purpose of making a bike that doesn't use shocks...
@bairnonessiewell normal suspensions use both springs and shocks. The magnets replace the springs. The shocks stop the bouncing around.
I was thinking something like leaf springs, same direction.
Also, definitely need to put some silicon or rubber padding on the magnets
9:12 there's a spark coming off that magnet and socket!!
Yeah, that's crazy!
Quite the snap there
If the current hub of the magnets are stainless steel, consider changing them to ferromagnetic materials like steel, it will force the magnetic field to go towards the opening, giving you more power where you need it and lessen the pull in the shielded directions, might even save your keys from those monsters.
Colin, You can increase the stiffness of the seat post and the joints by adding a second set of pivots, spaced a set distance away from of each other. Make the frame look like a triangle or trapezoid when viewed from the front or back. This changes the stiffness from relying on the moment arm of the bearings --> trying to twist a large assembly, instead of relying on tapered bearings roughly 50mm apart. If you you could space the pivot assemblies something like 100mm apart (without ruining the pedal and drive geometry), you should eliminate almost all the flex in the system that could cause the magnets to misalign when you take a large drop/jump.
you mean something like using elongated triangular bipyramids instead of simple tubes? and cutting the tips near joints to allow them to be wider?
@Godotan2Sure, that would work. It's more about creating a truss-like system that incorporates triangles. They don't have to be perfect, or optimized, but there is a reason that the construction, civil eng, and mech eng fields use triangles for added stiffness.
Yeah this is the only way I can think. It will look even less like a normal bike though
Agreed on building more like a space frame with triangulation. I think there would be gains to be had with going back to the smaller magnets for packaging and treating them with proper kinematics. Current setup without drawing it out seems to get progressively stiffer with a motion ratio at or less than 1. Such as 0.5in of wheel movement to 1in of magnet movement. Numbers are arbitary for the example. It needs to be something like 5in of wheel travel to 1in of magnet travel. If I had to guess with two 500kg magnets hes something 1/4 (sqaure cube law lol) of the advantage of a conventional spring/linkage having 1 spring of ~200kg. All that extra weight and compliance would do crazy things to the frame without good load paths/kinematics.
It would be possible to have a digressive motion ratio similar to mountain bike or dirt bike rear swing arm pivot where a small spring can act as a larger and longer spring. Check out the suzuki full floater suspension. There you can have a pretty ridged rotating assembly thats planar but with a spring that moves fairly linear in packaging.
wouldn't that block the pedals?
22:40 I am pretty sure it was his balls of steel that got magnetized than keys
first video i see from you the energy is amazing and i really liked it the video i don’t even watch bike stuff but im super entertained definitely will check out more videos
Imagine if 20:56 Colin's add sound effects to the montage😂
22:13 also it gets the massive potential crushing forces away from your gentlemans area which is a positive
24:50 I feel called out
I'm picturing Colin leaning his bike against a lamppost whilst he nips into the shop for tea and biscuit supplies, then having to cut the lamppost to get his bike back!
A Brazilian RUclipsr by the name "Metal Projetos" tried this idea a while ago, but he couldn't get powerful enough magnets.
Vim procurar esse comentário :v
I absolutely love that Colin uses music from small artists that send their stuff in. What a great way to use your platform.
but no rock music
he clearly broke his own scale which is why he knew to go so easy on his neighbours scale
The most important suspension is the front, to cushion the handlebars/hands from shocks! Some MTB’s only have front suspension 👀
26 minutes of awesome engineering with powerful magnets. I spent 20 of that holding my breath and counting YOUR fingers.
Right from the beginning of his YT career, Colin Furze has been amazing. A practical genius, with all the theoretical understanding, sprinkled with wit and comedy. And so great at explaining everything he does.
Massive respect, Colin!
Seriously! For anyone at home thinking of fun magnet projects be aware magnets of this strength can easily amputate fingers if you aren’t incredibly careful to avoid getting pinched between them. That bike looks amazing though! Excited to see MK2!
Build a twin rail frame like a motorcycle. By creating wider base you spread the torsion load out. You can install rubber bump stops on the faces of the magnets to help dampen bottom out moments and protect them from damage.
Circular frame not angular. Pivots points denote radius’s.
I agree, the base of the joints need to be wider. Creating a wider pivot point on each side would do.
The only thing that can bother with that are possibly the pedals, I don't know how much room there is to make it wider.
One other low-tech solution to make sadle part sturdy'er could be to weld smaller rods along side it on each side.
It's a simple solution done to old ( race ) motorcyles to make the rear-frame ( rear bridge ? ) more resistant to flexing.
@edwinbruckner4752 Can always go with a wider crankset for a wider bottom bracket. Typical mountain bottom bracket is 73mm wide, could move to a 100mm wide fatbike bottom bracket
@dulmi2317 yeah I don't know about bikes with pedals.
Although im a Dutchman, I hate bikes with pedals.
Best thing would be to trash this thing and start over, but this time with a 2stroke dirtbike or something :P at least something with an engine.
But thats my opinion :D
The pivots need big bearings, doesn’t look like he has any.
23:40 is a interesting visual .
I think you mean 23:36 LOL
Reminds of a 5 second music
@JeffreyDuddeky'all have to mean 23:10
Now make a magnetic pedal-assist, from a v-gate shaped /perendev magnetic arrangement /or halbach array. Can you do this? Thank you, god bless
12:59 colin rehearsing for the nutcracker this Christmas 😂
Nuts
+ what ever is hanging down
@weeder609 willyyy😂😂😂
@EnginesAndMetalYes, version 1 had me wincing, certainly testicular riskiness inherent in the design there.
Lol I had to look away
@leslieaustin151 i couldn't hear what he was saying all i was thinking was dont break dont slip 😂
"The bike frame I have won't work, so I'll just build myself a new one in the shed" is such a powerful flex, delivered so casually
Out of STAINLESS STEAL 🤯
Idk how those machining bits and wholes saws held up!?!
The build montage 1t 19:00 is beautiful.
As a metal worker, listening to the music and seeing a person being skillful with his tools, I don't know what it is but it actually brought tears to my eyes...I truly love this channel.
It's such a lovely song right? The artist is Nia Nicholls.
(Didn't know her before this video, she has a small RUclips Channel as well, let's show her some love!)
@LittleLionRawr Yes I know, because it's all in his video description lol :P
As a metalhead welder I personally absolutely dislike the music but the montage was awesome, it's almost therapeutic to watch
Improvement idea: change the Magnet Setup in such a way that it basically "Self Centers" - so arrange the magnets like this:
\ \
/ /
(these are supposed to be 4 magnets which are slightly tilted. If they are pushed together from left and right they willl try to stay in line rather than trying to twist the Frame)
Mechanical Engineer here - Really like the design Colin! I'd consider using linkage to achieve a reduction so you could have a mechanical advantage. This would allow you 2 distinct improvements: you could use smaller magnets and perhaps place them closer to each other to have a 'firmer' suspension, and you could have a much more rigid frame overall (you could even place them inside of tubes to really limit the deflection). You may also want to consider adding bump stops. Always love the videos and looking forward to the next one. Cheers mate!
Not a mechanical engineer here - I was trying to think of a how to phrase what I was thinking and this pretty much sums it up. I was trying to think of how to design the frame/pivots to gain a mechanical advantage. My middle of the road mount bike has the rear suspension shock/spring in front of the seatpost with various linkages. And I think the pivot/fulcrum on the front maybe doesn't help the magnets at all as well? I know he wants a floating in air look but it would be awesome if he stretched the fork and increased the rake and made a springer style front suspension with magnets for the ultimate style street cruiser vs a mountain bike style. Then he could make more of a twin tube frame so it doesn't want to bend out of shape.
Edit: Also using your idea he could make a threaded shaft or longer rods with some shims to increase the ride height or stiffness.
Oh, people were saying put bump stops on the magnets, but as they are rubber stops they could go anywhere between the frames, and thus leave the RUclips Thumbnail to be as cool as needed!
My solution would be a secondary frame that holds the magnets and a cable system going in front and behind the bike to pull the frame apart, rather than push it apart. All the stress would be at a single location, that could be framed safely, and essentially none of the magnets sideways forces would actually be put on the frame.
10:26 Hahahahahahahahahaha! So true!
Place two magnets at 45° angles.
\ /
\ /
Think of that as a top view. They can't touch plus there will be no lateral frame twist.
No, hee just needs to install two tracks to keep the frame in place.
@Amans_advice exactly
@Amans_advice oh so he needs to do the boring and ugly solution instead of this cool and elegant one?
You should sell them because I think loads of people will want a magnet suspension bike to flex to there friends and family.
They can just go build their own. Just gotta do like Colon, yeah?
@b@benbowers1321 Possible but I know I don’t have a welder
Great sound bite 16:06 "Anyway Colin shut up. Right. Now..."
Magnets act like a spring, but maybe you could try placing a copper or aluminum plate in front of just one magnet to act as a shock absorber as it moves through the magnetic field. It would be really fun to see. Great video, Colin!
I was thinking about eddy currents, too.
Yes, or (while not as visually appealing) he could encase each magnet pair within a copper tube, that hides the visal gap, but provides way more resistance like you mention.
Schould be TOP commentaire, Try with copper Collin !
An aluminum pipe might also work. The pole is not pointed straight at it, but the fields go all the way around. This way you could have both actions in one mechanism
I was also thinking it might need bump-stops to set the limits as well (not to absorb impact, but to dampen suddenly reaching the end of the travel). As the damping itself is already handled by the magnets, it just keeps the magnets/surfaces from ramming against eachother
This music/timelapse combo is one of the most enjoyable I’ve ever seen. 21:20
i am a marionete Nia Nicholls
Love to see Colin's child and engineer side in one video.
It sounds like it's from portal game
Imagine colin biking past a person with a pacemaker and them just dropping dead
This is one of the saddest comments I've ever seen
If after fixing the bending problem the magnets still touch sometimes it might be beneficial to mount at least one magnet on each set on to the top of a shock absorber that way if they touch the shock absorber can take the excess force. Maybe you could figure out what the maximum force the magnets are able to handle before touching is and find a shock absorber that is stiff enough that it wouldn't engage until that much force is reached anyway. That way the magnets are still absorbing all of the forces of normal usage, but in extreme cases you would still have protection from them slamming together and being potentially painful. Just a thought 🤔
It could help to put rotary dampers in the joints. They can be found in soft closing toilet seats as an example. You will have much less imidiate force on the Magnets this way.
You need some kind of dampening, which brings me to my idea to also fix the flexing issue. You can surround the magnets with a thick tube of copper/aluminium that goes from a magnet to the other. The magnets moving will produce eddy currents in the tube, which will dissipate into heat. It should fix your issue and provide dampening although I don't know if it will be noticeable, and i'm too lazy to do the calculations.
But then that would take away the very appealing “floating” effect that the bike currently has.
Yup, he attempted to solve the wrong problem.
Springs are perfectly capable of keeping the tubes apart.
Bound and rebound are a difficult problem when the unsprung mass is greater than zero.
I'm wondering if a block of copper between or on the magnets would work
17:50 that doesn't just look terrible. As a man, that's one of the more terrifying looking apparati that I've ever seen in my life.
I was also horrified and repulsed
@HalfFlat832I see what you did there.
@s@silkysixx magnets !
That's what I'm talking about!
Por lo menos se atrevió a hacer algo diferente a todo lo demás, ustedes solamente se conforman con llevar suficiente dinero a las tiendas y salir con una bici de fábrica ,el sabe perfectamente que ese invento no tiene futuro (todavía). Les recuerdo que ya hay estudios para usar esa fuerza en los ferrocarriles, porque no en una bici.? Bravo por tener el valor de intentarlo, por motivar a que hagamos algo diferente aunque nos critiquen,DaVinci hizo un montón de bocetos qué no funcionaron y aun así se le considera un genio. Saludos desde México.!!
Ngl that music made that build montage surprisingly beautiful on some of the shots.
Change magnets from flat plates to a cup and ball shape. It will resist the lateral forces causing your frame twist.
That montage was absolutely hypnotic.
The marionette song was insanely good. It's a bit different from the type of music Colin usually puts there, but it was very nice to have some very intelligible lyrics tell a story like that.
Such a beautiful song about two sexy lesbians who can't seem to get along after munching on each other's boxes. The girl riding the song had pubic hairs stuck in her teeth which made her obsessed with the other lesbian. I mean how much more beautiful can song lyrics become
all you need is a copper coil and you got power
15:48 Colin just casually stumbled upon the definition of dark matter, matter that has mass but does not interact with the electromagnetic field.
ah the universe is wood :]
I can't wait to see him build a neutrino bicycle
@Stevie-Jbest comment
So you're saying dark matter is just wood?
Soo, then we could now say that wood is dark matter then?
First off! Amazing!
Second off: If for the rear suspension, you mimic what you've done in the front, having that long horizontal bar with the magnets seated in the vertical direction, you'll greatly increase the distance between the rear magnets and the rear joint.
In other words, take the red rear magnet all the way back, above the wheel. Then, add a long bar from the seat to the blue magnet to oppose the red.
It should balance out the forces between front to back and make it even more comfortable/stable.
AND, you might even be able to mount cargo on the new rear beam to the blue magnet!
Cheers!
Also, to make it more stable, he could put some kind of rails underneath the magnets between the subframes. this way you still see the gap between the magnets but they're kinda guided so there are less twisting forces on the frame and bearings.
@Raruschmaru These are some really nice suggestions!! The two of you should reach out to Colin somehow, or I hope he sees your comments!
@Raruschmaru Additionally, while the length of the seat mount is mostly irrelevant for the forces exerted on the singular joint, it should still affect the force exerted on the magnets whenever the joint isn't perfectly below the seat and the downward forces are shared between the joint and whichever magnet is currently under more pressure, i.e. front magnet when going downhill and back magnet when going uphill. So anything you can do to shorten the distance between the mount and the joint could still help with that slightly.
In fact a negative ratio between seat and magnet would perhaps be ideal for the magnets (though worse for the joint I guess), but that would mean putting the magnets above the seat lol. Maybe my math is off on that one. Still, adding a backwards crossbar like the previous commenter suggested is going in the same thought direction and combines two improvements, so my vote is for that.
Speaking of joints, because of the double joint to make space for the pedals, the back magnet is actually much close to its joint than the front magnet. I can't think of it right now, but aside from lengthening the magnet/joint distance, there is probably a better (possibly double-) joint setup to improve the weight distribution between the two magnets. Would attaching the back portion to the front joint and the front portion to the back joint by crossing the frame have a positive effect? My brain is telling me yes, as long as the joint angle doesn't become too steep as the distance from the magnets would increase, but someone smarter than me will have to do the math because I'm sure there is a point at which it would be detrimental for other reasons.
So long as your cargo isn't metal 😂😂😂
@markaskew haha true!! But maybe then it'll just help hold it in place!
Must have another collab with Sam Pilgrim now.
Fox 2 with rectangular bars instead of circle bars that makes the bike more sturdy
25:00 absolutely clocked me there, I'm not even complaining the video was interesting lmao
So the main problem with your bike and it twisting is when you look at your bike from a front profile, it is completely structurally flimsy to any forces pushing from the left and right. That's mainly because to maintain the gap you turned the seat part of the bike into a massively effective lever. To overcome this you should redesign the part of the frame holding the seat up to be shaped like this when looking from the front:
/_\
So basically you want your bicycle to have a triangular profile. You should also do that for the magnet way up at the front of the seat since that has the exact same problem, there isn't really a reason it needs to float there, might as well have the seat part of the frame be triangular when viewed from the side as well. It would actually look really similar to how the frame looks at the rear tire if you rotated it clockwise a little (24:29)
To prevent the twisting, look at the double wishbone setup seen on the nose gear of a Cessna - Main gear Piper PA 28 also has a good diagram. . "Torque link" upper and lower. Your magnets take the place of the shock absorber in that assembly. You can preserve the openness of your current assembly, but control the ends wanting to twist out away from each other.
It needs to be a magnetic hydraulic hybrid system on the wheels.
19:40 damn, i have the same pair of safety goggles !
😂
~16:00 - *_Everything_* is magnetic, its just that most of the time the force is so weak we don't notice it.
In several universities across the world they have super high power "magnet bowls" that will levitate organic stuff, like wood or fruit or even insects and small animals 🤷♂
Or rather the magnetic forces of the particles are in random directions and so cancel each other out and we only notice them build up when they're mostly pointing in the same direction.
10:15 What if it Transitioned into a Transmission?
reading through all of these puns in the comments is my trans mission
Aliens already use EM for craft propulsion.
Cadillac sells this for their cars, or at least they did once. It was part of the Northstar system.
15:55 basically the reason we have the large hadron collider. Put stuff near other stuff, just at 99% speed of light 😂
17:25 Looking at the placement of the magnets I want to recommend you wear some very tight undercrackers to avoid the nutcracker effect.
First thoughts, although I’m gunna just take a pass and watch everyone else ride it for a Fews years first
There are few certaintys in life, but Colin's neighbour being a legit legend is one of them
Imagine getting your hand stuck between two 500 kilo magnets while unboxing
I'm just glad you didn't lose a finger to these magnets, it's hard to wrap your head around how strong they are and how they change from being dormant to snapping together at the right distance, crushing everything inbetween.
Got my hand between a 200 kilo magnet and a gascan I walked by.
And to no surprise, It hurts when a magnet sucks a 6 Kg LPG-tank straight into your hand and gets stuck...
@joachimgrek6920 omg. you were holding the magnet in your hand, walked by the gascan and got stuck to it? that's the kind of shit i'm worried about with these magnets, you really sometimes don't see it coming and then it happens so fast you got no time to react. hope your hand is okay though.
@moos5221 Three fingers and half my palm got hurt, but it could have been alot worse! Only some little cracks, so it healed in around a month. But I will never make that misstake and underesitmate a magnets force again!
Me and a friend used it for magnetfishing, and now it rests on the bottom of a lake here in sweden... Biggest thing I pulled up with it was a bit of railroadtrack around 70 cm. (little over 2 feet)
Please give this bike to Sam Pilgrim and let him properly test it
Who?
came to ask for this😁
Wouldn't last 2 seconds with Sam without having pivot plates and more linkages!
@flyerphil7708 he's a mad biker with a RUclips channel (missing a few teeth).
You could try designing the rear section like the swing arm of a motorcycle so it can only travel up/down (not side to side). However that would only give you suspension on the rear wheel. The front section is still a puzzle to solve.
That's awesome that you've created a bike that steals watts of pedal power.
