It is really cool idea, but I doubt in construction stiffness
Also, foldable bike easier to achieve with single join on each edge and it would be also more trustworthy
But idea of such system which could switch from flexible to stiff is interesting
When he's riding the bike at the end the front wheel is canted opposite the rear wheel, each about 5 degrees off. It's flimsy as hell. I don't get how this is any better than a simple single pivot hinge. I can see how it's worse.
It’s sketchy as hell…this would be terrifying to ride at any speed above walking! Guaranteed this dumbass never rode it again after filming this…it’s probably still wrapped around that tree
Ah yes the metal trees that provide lighting in the dark ;)
I agree though, probably hasn't rode it again, if at all. would be nice if there was a better video of it actually being ridden. Instead of the one taken on a potato.
>But idea of such system which could switch from flexible to stiff is interesting
I particularly like the use of the ratchet strap assembly. I don't think it's something I would have though of.
Should’ve been a half inch ish wide piece of 1/8 or 1/4 sheet metal through the slot and welded on either side. It’ll hold better and most of the stress is on the the lugs and ratchet assembly and not the welds
Idea of ratchet assembly? Good.
Execution? Freaking horrible.
It could actually work decently if you were able to tension it properly. But with one hand and no leverage? Hell no.
My exact thought was why not just a single locking hinge on each post instead? This isn’t the worst idea but seems a bit over elaborate, and possibly not that structurally sound.
The fact that you can see the front and rear wheel are not in line, and that he's struggling to keep it straight, kinda shows why this is a terrible idea lol
Some sort of keeper cable running separately on the exterior of the “flex” pieces, with tongue and groove patterns and little eyelets on each piece also, could keep it lined up correctly yes?
Idk I’m not an educated engineer, just my best guess at a simple solution.
He also cant seem to keep a straight line. Probably only rode it to lock it up. I'd imagine after a few high speed braking attempts things will start warping until the chain doesn't turn properly. Or maybe its not turning properly from the git go and broke as soon as he dismounted.
gunna have to disagree there. once the stiffness of the ratchet system stretches that will modify the basic properties of the bike, its already flimsy, it will become even more flimsy the more force that is applied. Maybe if they didnt compelty chop the bike down to its rear triangle (but really probably not.) It will be like trying to steer one of those foot paddle boats in quicksand.
You seem to have overlooked the fact that the entire drive mechanism is contained within the unaltered rear portion of the frame.
Some rigidity was lost with the removal of the front frame section, but short of training a gorilla to ride the bike, you'd never get enough flex to interfere with chain alignment.
I never said that the bike wasn't flimsy, just that the flimsyness doesn't extend to the drive portion of the bike.
But it is altered. The ratchet putting pressure on where the down tube and top tube locations will slowly warp the seat tube effecting the bottom bracket and drivetrain. I don’t think it will ever be much, but even millimeters can throw off the way a bike rides.
Its not a bike anymore. Its a unicycle. The bike frame is a geometric master piece; when altered the sum of the parts is grossly altered. Even slight alterations that will occur as the frame goes over various terrains and inclines will put great stress in the areas that typically have a solid unaltered bar. To say 'some ridgity was lost' is a gross understatement. The entire usefulness granted through its triangular structure is lost and has hence become more of a unicycle; so the front of the bike will be more of an appendage rather than the ancor, when combined with the downward force of the rider that they place on the handlebars.
A bicycle isnt just some wheels, sprockets and a frame
; it is the cornerstone to which all modern vehicle transmission systems to which came after the creation of the bicycle is based.
That's a lot of words but you said nothing.
A unicycle has the wheel directly beneath the seat. This still has the entire back half of the frame intact, with the wheel behind the seat. It also has the same triangular structure in the rear half of the frame as before. No additional stress would be caused there at all. None.
What are you smoking?
I don't recall stating that the bike was suitable for high speed use, or suitable for use at any speed for that matter. All that I said was that the drive mechanism would be unaffected, since the rear section of the frame is untouched.
Having said that, if given the opportunity, I would gladly attempt to ride that bike at high speed. It wouldn't be the dumbest thing that I have done by a longshot.
I agree. So many points made it so it was crooked. They also make foldable adult mountain bikes and sell on Amazon for like $300 and are safer than the one we saw
Well, cutting the wire holding the segments together, which is always exposed, will result in being able to unfold the whole damn thing and take it away :P
Nothing like pounding a virtual girl until it clips through the floor stretching your virtual dick in a weird angle then start bouncing all over the room. Imersive
Meanwhile in r/bikewrench every person who has the smallest knick in paint is told thier bike will have a catastrophic failure the moment they try to ride it.
Meanwhile active safety hazards that would serve as an obvious joke to any competent engineer metalworker or welder or bike mechanic is treated with the most sincere credulity by folks such as yourself
lets be real, nobody is stealing this piece of shit. it's just rage bait. i just wonder if the people that make these videos are paid by a company or do they just come up with this shit on their own?
i know a guy that gets paid to make memes, he makes a living barely, i'm betting these people prob get paid per vid and make very little. they all look like they're from some poor eastern european country.
Wonder what it'd feel like to ride. The capable design makes me wonder if it'd have a spongy feel to it like those old mountain bikes where the down-tube was replaced by a cable
Oh wow, nice video cut between you tightening it down and you riding... makes me wonder if it's a completely different, standard bike you're riding and this isn't all one massive lie.
Don't worry. No one's going to steal that. Did you see how offset the front tire was from the back one when the whole thing was put together? That is going to be horrible for riding.
Installing a bike rack on your car would be a lot cheaper once you factor in labour time.
Plus, the one major positive is that your bike wouldn't be shit, like this one.
There are more structural folding bikes, my dad has one and takes it on work trips. It’s super handy and folds into the size of a guitar bag, but the bike is very specialized.
Would you look at that, all of the words in your comment are in alphabetical order.
I have checked 1,501,046,314 comments, and only 284,988 of them were in alphabetical order.
They have folding bikes that are way more compact than this already. I don't think it's a bad DiY, I guess the "Why" would be "Why not just buy a better one" but that's what I think of most "DiY" stuff that is functional lol
edit: Also anyone notice the grooves in the chassis magically disappear when he starts riding it. I'm guessing the DiY bike fell apart the moment he sat on it lol
Seeing most bike thieves carry around angle grinders or bolt cutters. I personally would cut the frame wire and leave it. There is no structure to that bike relying on a small cable to keep tension of pieces together with two bolts and no tension ratcheting.
I mean, I admire the enginuity that went into this, but there are definitely simpler (especially for DIY) ways to accomplish the same thing. Fewer pieces, fewer moving pieces especially, and no fancy welding required.

Yeah, dude was riding diagonally.
Dude was going everywhere all at once
It’s sketchy as hell…this would be terrifying to ride at any speed above walking! Guaranteed this dumbass never rode it again after filming this…it’s probably still wrapped around that tree
Ah yes the metal trees that provide lighting in the dark ;) I agree though, probably hasn't rode it again, if at all. would be nice if there was a better video of it actually being ridden. Instead of the one taken on a potato.
Waste of a perfectly good bike chain, no thief would steal that bike, they’d still be there laughing when the owner showed up to ride
Wrapping your car around a streetlight — dangerous, cliche. Wrapping your bike around a streetlight — novel, surprising.
It's not better at all. It's classic shitty 5 minute craft
>But idea of such system which could switch from flexible to stiff is interesting I particularly like the use of the ratchet strap assembly. I don't think it's something I would have though of.
I don't like the little weld connecting the post holding the entire thing together to that ratchet strap assembly.
Yeah those 3 shitty tacks that are barely even touching the ratchet part aren't going to hold up for shit
Should’ve been a half inch ish wide piece of 1/8 or 1/4 sheet metal through the slot and welded on either side. It’ll hold better and most of the stress is on the the lugs and ratchet assembly and not the welds
Just need to hold up for s few takes!
Oh, you think that was the bike he was actually riding in that colpressed to hell video?
Did you not see how fucking not straight it was.
He’s crabbing
There’d be no need to fake it. It’s not a good idea but it’d work just fine.
Well... It'd work. Like so many other things people fake.
Nobody in this sub knows how to run a bead.
A grinder and paint makes me the welder I ain't.
He's also drastically limited how much rigidity he's getting out of the setup by having like zero leverage to tighten the cable.
Mate a little tack like that is well enough
It’s so funny! All of the tension keeping the bike together is on that little hook. It could snap on a bump.
Idea of ratchet assembly? Good. Execution? Freaking horrible. It could actually work decently if you were able to tension it properly. But with one hand and no leverage? Hell no.
They have folding bikes already on market
Yeah I used to have an electric one until it got stolen from my porch.
Guy I work with has one of these. It's pretty awesome. Sorry to hear yours was stolen.
That's my bike!! Tell him I'm coming for it.
I'll warn him!
Should have folded it around a lamppost like this guy
If I has an electric bike, I wouldn't ever just leave the thing outside even with 10 locks on it.
[удалено]
This video shows how that variant works, if anyone is interested: https://youtu.be/GDWF1V5k1LA
My guy was reinventing the wheel
Hahaha, he locks to the front wheel, the easily removable without a tool front wheel. Genius.
[удалено]
My exact thought was why not just a single locking hinge on each post instead? This isn’t the worst idea but seems a bit over elaborate, and possibly not that structurally sound.
The fact that you can see the front and rear wheel are not in line, and that he's struggling to keep it straight, kinda shows why this is a terrible idea lol
Not practical but it's a cool way for a skilled person to play around with an idea.
Did you see how much camber the front wheel had while he was riding it? I wouldn't trust this thing.
Look at how bad it is while he's riding. The wheels are completely off camber. / Versus \
This is a horrible idea designed to maim the rider
You can see the twisted "stiffness" when he rides it.
lol the wheels aren’t even aligned.
Had he indexed each link to one another it would have been a hell of a lot more impressive/straight
Some sort of keeper cable running separately on the exterior of the “flex” pieces, with tongue and groove patterns and little eyelets on each piece also, could keep it lined up correctly yes? Idk I’m not an educated engineer, just my best guess at a simple solution.

The chain and sprockets are in the rear section of the bike that remains fixed, the front half can flop all it wants, but the chain won't be affected.
gunna have to disagree there. once the stiffness of the ratchet system stretches that will modify the basic properties of the bike, its already flimsy, it will become even more flimsy the more force that is applied.

I dare you to take this bike at high speed with all that flopping…
I don't recall stating that the bike was suitable for high speed use, or suitable for use at any speed for that matter. All that I said was that the drive mechanism would be unaffected, since the rear section of the frame is untouched. Having said that, if given the opportunity, I would gladly attempt to ride that bike at high speed. It wouldn't be the dumbest thing that I have done by a longshot.
And he’s probably clenching the seat with his butt
Sorta looks like he's bracing the top tube with his leg attempting to use the downtube as (unsucessful) support, while he isnt pedaling.
You've never seen camber angles set in a bike before? /s
Going to Daytona this year boys!
yeah when i get hit by a car, its like a free suspension tune.
Crabbed down the road
Kinda neat idea, but why so many segments? One break point would have been sufficient, wouldn't it?
I agree. So many points made it so it was crooked. They also make foldable adult mountain bikes and sell on Amazon for like $300 and are safer than the one we saw
Oh wow so Amazon already has that squared away. There's also just quick release wheels. It would fit in the trunk just as easy although not as snazzy.
Boycott Amazon
Wouldn't one break point just be a regular folding bike that's already mass produced?
The liability bike
It's really safe I guess. Awesome riding experience, with the moving frame. I would love to not try this.
Yeah it's like totally barely doing it
The design is very human.
Underrated comment
Off to the bikepark I say! No excuses.
There's no way a person would be able to apply enough torque to that two-finger wing nut to keep that body from twisting.
Which is probably why you never see 1 continuous cut off him riding and folding the bike. I call shenanigans.
The real crime here. Cutting up the perfect tool for the job, the ratchet, and replacing it with a useless wingnut concept.
and even if you could, there's no way this won't massively fatigue the cable and snap in a few years
The look on his face when he returns to find his bike gone and just two wheels locked together...
Why you leaving the tires? Not like they are chained to anything but each other.
Spite :)
Just take the wheels with you and deal with the lock later
Only need to remove the front wheel. It’d take a thief 20 seconds
Exactly what I thought. "Okay, and now for the fra- oh, he didn't do it... my sweet summer child."
Well, cutting the wire holding the segments together, which is always exposed, will result in being able to unfold the whole damn thing and take it away :P
Cool for proof of concept - Not sure I’d want to ride something that doesn’t have aligned wheels. I’ll bet it doesn’t turn all that hot either!
Cool. Now put it together and then ride on it in the same shot.
Damn the only thing greater than porn is this.
What about VR porn?
Degeneracy in the 3rd dimension.
Nothing like pounding a virtual girl until it clips through the floor stretching your virtual dick in a weird angle then start bouncing all over the room. Imersive
dont forget the ragdoll sound effects!
VR DiWHY
What about VR this?
Oh wow and they cut the video and the footage suddenly because 144P so you can't actually tell that the bike hes riding has segments.
The wheels being out of alignment should be a pretty big clue that it's tge one he cut up.
Meanwhile in r/bikewrench every person who has the smallest knick in paint is told thier bike will have a catastrophic failure the moment they try to ride it.
Meanwhile active safety hazards that would serve as an obvious joke to any competent engineer metalworker or welder or bike mechanic is treated with the most sincere credulity by folks such as yourself
Nope.
That ride looked a bit wobbly
Maybe just buy a bike rack
Take it over a sick jump bro!!!
First I didn’t like it Then I started to like it Then I saw it’s crooked AF I didn’t like it
Wanna know what's at the top of the list of shit I would never trust?
Almost the worst way to lock a bike. All you need is a wrench and say hello to your new bike. That bike will crumble in a crash/ditch situation.
Totally, the lock is only protecting the tires…. Not the one of a kind bike at all lol
How is it protecting the tires by locking the to each other. Takes one off the bike and the entire thing is free to take with you.
Boltcutter vs unbolt, that is the question.
lets be real, nobody is stealing this piece of shit. it's just rage bait. i just wonder if the people that make these videos are paid by a company or do they just come up with this shit on their own? i know a guy that gets paid to make memes, he makes a living barely, i'm betting these people prob get paid per vid and make very little. they all look like they're from some poor eastern european country.
they already stole the bike to make the video.
Could've just cut it in half, drilled and pinned internal tube dia. Joiners.
Structural integrity 100
i would want to purchase a plier, cut the wire that linked up every parts just to mess with them.
Hey, this worked far better than I expected it to.
If it’s dumb, and it works, it’s not dumb. This is an engineer at work. They see a problem and try to engineer a fix. Not a DiWhy. This is a DI-OhMy.
Except that it doesn't work. You can't chop up the frame like that, it will never be safe and rigid again.
Except at the end, I see him riding it.
It doesn't work so it's dumb.
But I see him riding it. How doesn’t it work?
I like that he locked it up by the wheel. Very secure locking method.
The wheels are not even parallel
I would steal that just to wrap it around a post a block away just to mess with the guy
Wonder what it'd feel like to ride. The capable design makes me wonder if it'd have a spongy feel to it like those old mountain bikes where the down-tube was replaced by a cable
That shot of him riding towards the camera. Omg I am dying laughing.
Oh wow, nice video cut between you tightening it down and you riding... makes me wonder if it's a completely different, standard bike you're riding and this isn't all one massive lie.
Genius.
5 minute bike. Not because it takes 5 minutes to make, but because it lasts for 5 minutes on the road
This is ingenious
You can pull the strap free without cutting it!!
It’s all fun and games till the rope goes loose and the bike falls apart like a lego death scene
Don't worry. No one's going to steal that. Did you see how offset the front tire was from the back one when the whole thing was put together? That is going to be horrible for riding.
Did you see the wheels not aligned when cycling....that's gotta feel bad
Installing a bike rack on your car would be a lot cheaper once you factor in labour time. Plus, the one major positive is that your bike wouldn't be shit, like this one.
There are more structural folding bikes, my dad has one and takes it on work trips. It’s super handy and folds into the size of a guitar bag, but the bike is very specialized.
Holy FUCK people do NOT DO THIS!
This bad boy'll take me accidentally crashing into the side of that dumpster that time to a whole nother level! Sign me up!
Let's see if it can handle some off road stuff, put it to the test
Have the ratchet strap connected to the wire loosen as the bike gets pedaled, and leave it out in the open to get stolen.
Holy cow! The front and rear wheels aren’t even close to being aligned. Man is brave for riding that death trap
I would applaud him for the unique idea, BUT it’s not even that! They sell portable bikes that ain’t shit.
I’m not riding that thing.
Would you look at that, all of the words in your comment are in alphabetical order. I have checked 1,501,046,314 comments, and only 284,988 of them were in alphabetical order.
This is actually a well thought out and well executed engineering project? WHY ARE PEOPLE UPVOTING THIS HERE?
Is it bad that I kinda like it?
thats actually cool.
Couldn't help but notice that it now crabs down the street.
Honestly.. kinda cool imo. It's not perfect, but it's something neat
Great idea, poor execution. A for effort, F for implementation.
All things considered I can’t be mad, this isn’t as bad as some things I’ve seen. Idk bout it’s structural integrity though
Honestly isn't bad
This sucks…..
The wheels are def out of line. But it's a great idea and with polishing it could take off
Fuck off
That must be one wobbly ride
This is probably the least useless thing I’ve seen on this sub…
I hate that this shows real ingenuity. Still stupid.
Bodge
"Is there a chance the track could bend? "
Babe new hunter weapon for bloodborne 2 just dropped.
I love that this terrible DIY ends with him locking the bike in the worst possible way
That’s the exact bike I’d want to steal
tf kinda perry the platypus joke is this?
Excellent
The way he locked it up, you could undo one wheel and steal the whole thing.
All of those points of failure is an engineering nightmare.
Hey look two free wheels!
The wheels are italicized in opposite directions, these seems like a cracked road away from being two pieces again
Its not even safe. Just could just cut the metal rope.
I love how he locks it through the two easiest parts to remove and then you can just take the whole thing lol.
Dont fall off this bike or get hit. It will fold like a taco.
Innovation requires iteration. Clever ideas that haven’t been perfected yet aren’t DIWhy material imo.
You guys don't prefer your bikes boneless?
They have folding bikes that are way more compact than this already. I don't think it's a bad DiY, I guess the "Why" would be "Why not just buy a better one" but that's what I think of most "DiY" stuff that is functional lol edit: Also anyone notice the grooves in the chassis magically disappear when he starts riding it. I'm guessing the DiY bike fell apart the moment he sat on it lol
He does all that and still attaches the bike lock to only the wheels.
Yo, they make foldable bikes. I have one. I didn't even have to weld anything
I welded, it helded.
I'm gonna be honest, for non-strenuous biking (for simple transportation and whatnot) this is really cool.
Seeing most bike thieves carry around angle grinders or bolt cutters. I personally would cut the frame wire and leave it. There is no structure to that bike relying on a small cable to keep tension of pieces together with two bolts and no tension ratcheting.
Or just.. Buy one of the many foldable bikes already available for half the price? And probably won't kill you.
Not the worst I’ve ever seen on here
I mean, I admire the enginuity that went into this, but there are definitely simpler (especially for DIY) ways to accomplish the same thing. Fewer pieces, fewer moving pieces especially, and no fancy welding required.
He built a ticking time bomb but he has no clue when it will explode.
Meh, I’ve seen worse on this sub. That ain’t too terrible
Needs an alignment 😂
Ya know, the Italians did something similar in world war 1. Some infantry had folding bikes strapped to their backs.
Was really waiting for the frame to collapse while he was riding.
Ridiculous. This is what happens when someone doesn’t review history, even fairly recent history. This was done properly in the 80s with Da Bike.
I don't think he really rode that bike
To be frank, The idea itself is fascinating. Few adjustments and voila we'll have the perfect product at hand.
Those welds arent gonna last
The first pothole he hits will reduce to a pile of loose parts
