That bike might ignore physics, but physics sure as hell did not ignore that bike
You can get physics to ignore you, though. You have to simply throw yourself at the ground, and miss.

I can see a problem with the split wheels: constantly fluctuating turning radius. about half the time you have a normal turn radius, another about half the time you have a much longer turn radius, and a little bit of overlap in-between. That may be the reason why turning is weird or hard. Not sure how to fix the supports for the rearmost half-wheel, thought. Goodluck!
Also the back half wheel is putting too much strain on the frame. Because it's so far back, that's the whole reason it broke. It's just a design flaw
Maybe just add a triangle structure along the back so that it shares the load, could put a basket in the back to further improve functionality
Maybe if the rear wheels were side by side in a triangular layout as mentioned above.
@@neurofiedyamato8763 then you would have side to side wobbling with the ground contact point while riding. Even if you build them in as dualies.
Exactly, what I thought. Tight turns with changing rear ground points will get wobbly and the always changing forces on the frame don´t help either
the biggest issue with structural integrity is that since you used a normal bike frame, while the middle tire is on the ground the weight distribution is normal, but while the back tire is on the ground the lever arm length is much longer, easily tripling the force that the bike frame has to resist.
what I would do is put an extra connection point higher up the frame (probably right at the base of the saddle) that connects all the way to the axle of the back wheel. perhaps even building a crane like skeletonized structure.
Another thing, yea sometimes the split wheel would help with curbs and stuff but what happens when you think you wont hit a curb but as a tire does it still manages to hit the curb with the middle wheel? It wont his about 1/3 of the time but you cant guarantee that you will only go over bumps using the small portion of the missing parts of the weeks thats not how tires work
then what if you had FOUR half-wheels instead, one offset pair in front and one on the back, synced so that always either wheels 1 and 3 or wheels 2 and 4 touch the ground? that'd be the same distance between wheels and weight then
(this is mostly a joke because I realize steering might become VERY strange)
@@ilonachan the issues isn't the distance between the wheels, it's the distance between the back wheel and it's attachment point on the bike frame that causing problem.
Just wanted to point that out.
And since the force is fluctuating, i would guess the dynamical peak is higher then a constant static stress.
Not only is the stress increased by extending the leverage, but the stress alternates as the half-tires swap touching the ground, which then makes it a dynamic load.
Which can cause structural failure at lower loads compared to static ones.
Or to put it simply, because the large stress comes and goes frequently, it's even more destructive.
I know the video is a joke but here’s a list ig:
-For “ride well” I couldn’t possibly see how it would. During a turn you’d notice the pivot point change markedly by multiple feet from a somewhat normal bike to an extra long limo bike, and then back and forth. Secondly airless tires. A good portion of a bike’s suspension comes from the air in the tires. No air=less suspension=less comfort.
-Practicality should be on that list. One of the bicycle’s feature traits that makes it a viable option is the comfortability in a relatively small form factor; you can take it upstairs into an apartment if you wanted to.
-Cost is also a factor. For the seemingly one single advantage (half in the 50% chance you hit the curb with the front wheel anyway) the spilt wheel has on normal bikes, it would cost much more in material alone, and can be easily remedied by just taking a different route or dismounting and picking up the bike.
As for the tires, his homemade airless tires are not great but proper airless tires exist that have the needed suspension.
Yeah I don't see any advantage with the curb. One can't even properly raise his front wheel and have to just ram it. As for the back half wheels I would name them limbs cutters.
I would say that one single advantage of hitting the curb with only front wheel 50% of times is very much a disadvantage. Having a chance hitting it is bad as you cannot be properly prepeared for actually hitting the curb.
I will choose EUC every time over this abomination - only hit a curb once, 100% chance, very predictable - as I actually do ride an EUC.
@@volodumurkalunyak4651 you can choose to always expect it to hit. Problem solved
@@TOBY-jy7bz then the bike does not solve any problems. Its like a cache but without any of the advantages. Just like a cache, you might sometimes hit or miss. But unlike a cache, the bike performs worse with it than without it. So... yeah...
There are two main problems with this bike, there is a huge stress concentration at the middle of the beam where the back wheel connects to the shaft if you were to redesign this, connect it to the top part of the main triangle and add another support to make another triangle. The other main problem is the changing turning radius, this creates a constantly changing force, people with a background in engineering or metallurgy they will know that aluminum will always fail from fatigues under cyclic loading, you can avoid this by using a steel bike frame. I can’t think of any quick solution for the wheels other than just making them wheels 😂, and the wheel problem will probably be amplified from the added weight of my proposed solutions. Overall fun project!
Nice to see this vid come to fruition- when I saw the story originally I had no idea what you were gonna do with it, this was a surprise
Bro I didn’t expect to see you here, thanks for al the help in my math class. I would’ve totally failed the test about Obama if it wasn’t for you
when this bike becomes normal then jack will have the last laugh lol
hes not the first to make this video. Ive seen three other videos of people doing this.

This won't happen because this bike design is costly, less durable, take more space and harder to navigate

Why do people do awards speeches for RUclips comment likes?
I think I know what caused the structural failure of the metal in the back: Because it is split wheel, the center of gravity constantly changes, meaning stress is put on it every time a different wheel is touching the ground. It's as if you were constantly picking up and dropping the back of the bike rapidly. It gets especially bad when on the back wheel, because the structural integrity is compromised due to the extra distance the frame has to support.
People may hate me for saying this, but this is an unsafe flop. Just to get it to not break, you'd have to make significant investments into redesigning the frame. However, it will always be an unsafe bike, because physics treat it as if it is instantly growing and shrinking in length every rotation. This means that the bike isn't useful beyond being a novelty, because trying to race with it WILL get you killed. Even then, I wouldn't trust riding this bike, because there's always gonna be an emergency circumstance where you need to turn quickly, which you won't be able to do.
If it ever somehow makes it to production, there is going to be accidents, and it will probably receive a ban by the government. I only wish I could describe the problems with visual aids, but sadly can't in a RUclips comment.
In my personal opinion, Mile 16 resembles Victoria, Australia more than it does Minnesota
Also that bike looks really cool tbh, the only caveat of it (other than it breaking and being hard to control) is that bike infrastructure may need to be adjusted significantly if it becomes big, since most bike lanes in the US are thin stretches of land, and passing someone with or on a bike like that would be kind of hard.
Mile 14?
@@griffinshorts785 Yea my bad
Doesn’t really look like Victoria to me, doesn’t have the right vibes. Maybe if the road was a different colour?
Hey I’m from victoria, looks nothing like here though lol
@@wormworm580yeah doesn’t look like vic at all idk what he means by that
Jack has really gotten the hang of telling really good stories with really good packaging... I'm very impressed!
0:48 i gotta appreciate the shadow masking
I'd recommend putting another split wheel in fhe front that is in opposite phase to the back split wheel, so no matter what you'll always get the advantage of the split wheel.
A weld would never work for that piece because there’s too much pressure on that spot. I wonder if the split wheel idea would work with 4 half-wheels (and maybe have a small rubber tire in the middle if the weight falls on the center) built like a quad.

Id make the wheels like 5% longer and curve a little bit more at the end to prevent the tire breaking off.
For the structure, try to add suspension, it should help.
Your videos are unlike any other videos I have seen!! You put real hard work in them and your videos are so interesting! Keep up the work and remember that you're gonna be big one day :)
great storytelling! loved watching this
The split wheel looks so awesome! Looking forward to a version 2

love the storytelling throughout this, wasn't planning to stay more than a min but stayed until the end fair play
These videos are so goofy and they make me laugh! Keep up these videos!😆😆😆
Go Blue! Good job Snad for building it and overcoming the shipping, but you can only trust Louis' welding skills as far as you can throw a welder.
I love the split wheel. I was wondering if there's any tubes in the bike. Maybe half tubes since it is a split wheel. THEN.....Your tire shredded. Completely answered my question. Hot Bike! I've seen it a few times on RUclips. Amazing.
That is so cool. Can't wait to see how the final version turns out.
Who thought that having the weight constantly shifting from one wheel to another would put stress on the welds😅
Man I do sure love the audio balance of this video, with the voices quiet and the music and sfx totally not being just a bit too loud.
That. aside. Very cool vidgeo man, it's neat.
This editing and it is insane. You’re so good
Your editing is fantastic dude. Keep up the amazing work!
If you like this you’ll love the original. Ryan Trahan
Building out a proper rear wheel frame is definitely the way to go to fix your structural issues there. With rhe way its levered out so far you have huge stresses at your joints and uneven wheel loading which is probably the core of your structural issues.
Cant wait to see mk2.0!
Two firsts! I hadn't yet seen a bike like this before, and I hadn't yet seen an advert for an essay writing service that relies on a large language model. Good pairing! These things will work equally well!
i just found your channel! you seem super cool and entertaining and have gained a new subscriber :D
This is the first time I have ever watched a video of yours. RUclips plopped you into my reccommended. And you're entertaining enough to earn my sub
Let’s take a moment to appreciate the fact that they put a shadow under the mile indicator
I work at Home Depot and I can tell you: Yes, you can indeed buy a power tool, use it, and return it for pretty much any reason within 90 days of purchase. Awesome video by the way dude! I'm a bike enthusiast and this was a thrill to watch!
I'm all for innovating old things we take for granted. I cannot express how impractical this is purely based on length.
A few things you can't do with this bike:
1. Go on a train
2. Pop a wheelie, drift, or do any kind of agile manoeuvre
3. Park in 50% of bike stands
4. Fit it inside of my house
Great video keep up the good work man
Amazing video! Love your content!👍
Amazing story such an underrated RUclipsr ❤
Cool video and such original editing style 😮
Yknow what i like about bikes?
Being cheap, small, easy to repair, and easy to ride.
In comparison, this bike is more expensive, 50% longer, has a back wheel you can only find from specific sellers online, and quote "turns like a bus", which sounds like a knock to the 4th point.
If you want more shock resistence, use one of many bikes already built for that that will all achieve atleast half of the above criteria, or drive a car.
Maybe a bike centric place could make use of this, but probably not, as they are less likely to have bumps in the road that this bike is built for.
Fyi, the correct home depot fix is brazing with an oxygen enriched torch. Even silver plumbing solder and propane torch would work if you make a sleeve.
I just want a clear explanation on how this bike "ignores physics."
mmmb brain phisics?
I'm liking the way that this channel is headed
Fascinating concept! Hope you get the structural issues sorted out for 2.0!
I just learned to Nollie a curb on my bike or clear it all together if going fast enough. I would have never thought of the need but cool work around!
To be honest, it looks cool!
I don't know if I would buy it, but definitely try it for fun. It should be put in tourist locations!
I think the simple solution to the bike problem is to put more support at the weak point (ie: 2 bars from the seat to the broken part
So the clip at 7:20 showed exactly what the problem with this bike is. When the rear wheels rotate there's a few degrees where the bike is dropping down rather than rolling which is causing excess stress on the frame as well as causing that wheel to have issues.
Just saw you at Vidcon recording some video, really cool to see you!
4:28 "I'll always remember his name"
You're super underrated. Love your content. Keep it up man. To do all this work while in college. Mind blowing.
Never seen you make a video like this im impressed.
Just copied Ryan Trahan
This reminds me of when I played Belegardh in a club at our local university. Alot of people would stop by and watch, but they would freely admit they wouldn't be seen doing it in public.
Interesting design, it does have a slight alteration on turning radius each rotation of the rear tire. This idea is innovative. Cudos for the idea. Fun story.
The girl telling to put some sunscreen on is kinda wholesome ngl
To fix the joint issue, you could use a rubber or plastic cast around it so the metal wouldn't face as much stress. That or just continuing the bars at the fault point so they both connect to an perpendicular line so the force isn't thrown against a single weld point.
as far as riding smoother, it seems like it’s just a gamble, you have a 50/50 shot of the curb going in the wheel gap sure, but if not you’re gonna be hitting it with the front wheel and *both* back wheels!
Also if the curb or obstacle does go between the wheels, you have that end of the back wheel being responsible for basically lifting the back half of the bike, which seems like it would be both mechanically not very efficient, and put a lot of wear on the parts
This was very entertaining to watch.
That was an awesome video 🙌
This video is so good!
I hope a v2 will come
insane edit and video
keep up the good work
lets gooo thanks fro the video jack
Your bike ignored physics but physics didn't ignore your bike.
incredible, this video is the only proof that the Home Depot thing wasn’t a fever dream 😂
"The design is very human."
the editing is on point, exactly like ryan trahan
0:47 i love how he added a shadow to the text
What a great video storytelling was great
In the next design of the split wheel bike check the load factor for the rear wheel as that connection is going to have the most stress causing the inconsistent ride height and shearing of the metal to help with the break we see in the video either add a support arm that connects to the main body where the seat is or have the connection point at the top where the arm leading to the break connects. My best guess for the reason that part broke is that the back wheel once it was carry that full weight was acting as a lever pushing the connection point that broke downward and in towards the central beam. That added with the force of your weight being pulled down over top of that point led to the break.
Structual issue is quite easy to spot, that angle where it broke is far too sharp of an angle, with no real support for it... right under where all the weight from the rider would be stressing things the most.
This is easily fixable though, you simply need to either:
-Add 1 more support bar going from the junction right below the seat, to where the rearmost wheel connects.
-Move the current support bar to the junction right below the seat.
I'd personally go with the additional support bat for added structural stability, but just moving the current support bar should be enough to spread out the forces properly.
I can't imagine it is very comfortable with air-less wheels, and I love how low the bar of '100 miles is durable' is!
Hilarious video.
oh my god even the text has shades that is so cool
Kinda confused thought I was watching Ryan for a sec also interesting seeing this concept as a bike instead of a motorcycle. The motorcycle did good until highway speeds.
Nice video! Keep it up
The structural stress on that rear part is what caused it to break since by elongating it you’ve made it a giant lever in effect. Try to add something like a triangular truss to offset the weight and stress placed on that last beam so it won’t break as easy.
I think this bike as a theoretical idea, has a fundamental flaw: the functional reason for splitting the wheels was to more easily make it over curbs. However, the back wheel doesn't suffer from curbs nearly as much as the front wheel does. And you can't really split the front wheel because that's gonna make it hard to steer.
So basically, all this bike does is looking cool and making it harder to turn.
As a fellow ginger who just got off of being sunburnt, I feel your pain
Jack's teachers seeing the sponsored segment:
I stayed till the end, that was epic
great video if the structural problem gets fixed i would totally buy it
At 1:18 I don't know if I believe the curb really will get "missed". So you have a video showing that specific "advantage"? Wouldn't the end of the when arc pick into the ground? If it does make it easier, I think the tires should have a smaller radius near the end

Look mom I am breaking the law of physics
Have you tried making a split rail bike with the 2 back wheels next to each other? Would that work or at least improve turning? Note: not like a tricycle but an 3 or so inches apart from each other. Idk
Is it just me that thinks this is a bit funny knowing that listening to the BGM in the middle of this video reminded me of Rainbolt playing Geoguessr and so now I'm watching this play out but also knowing that he uses this BGM while guessing where he is on google maps and ending it out with a "nice" or "we'll take that" and for whatever reason I'm lowkey enjoying that
It would be even better on bumps if the front wheel was split too. This way neither wheel would be impacted.
Failed the same way as Bikes and Beards version. In their case, the alternating change in the length of the lever arm holding the rear wheel made the suspension ride like a horse. The same issue in your ridged mount caused a stress fracture. Your tires also tried to to self uninstall. Their tires did self uninstall, on th interstate.
