Imagine designing a bicycle without triangles. Every joint needs to be overbuilt, because there’s no structure from the geometry. But you make sure it still has a top tube, so its just as hard to mount and dismount as a normal bike. Incredible!

Hey, look here buddy. You can’t be your own comment thread and post all the plausible responses yourself like that. You’re putting all the trolls out of work.
doesn’t that prove their point? they all look overbuilt, as the original commenter said.

Carbon fiber has very limited lifetimes when used for something with a lot of hard impacts, so if you’re not sticking to smooth surfaces the bike can literally split apart with little warning

I Googled “motorcycle carbon fiber wheel” and autocomplete immediately suggested adding “failure” and doing that search has endless relevant results

The meme shows only bikes with flat handlebars, like commuter bikes intended for transportation.
Every bike you posted are high performance racing bikes with specialized aerodynamic handlebars.
Different priorities. Triangless bikes with a top bar is not a good idea for commuter bicicles like the ones in the meme.

That top one is kinda sexy ngl
Yeah why not keep the seat tube and delete the top tube?
Compliance but this is a very very extreme example - you’d hit a bump and the top tube would flex, kinda like a diving board, and smooth out the harshness. I’m not even sure this bike exists but that would be the practical purpose of such a design, but most manufacturers tend to go after the seat stays (Salsa Warbird, Bianchi with Counterveil, Moots Routt YBB) or decouple the seat tube from the top tube and allow it to flex due to seat tube angle (Trek Isospeed). Carbon’s kinda fickle and engineers are constantly trying to figure out how to finesse it into feeling less jarring and rigid
This bike does not exist. This is part of a series of theoretical renders from what must be 15 to 20 years ago. When carbon fiber was kind of a new material to the general consumer. The premise was they could not only reduce the weight of the material but because carbon fiber was this space age super material that could melt your tits off if you looked at it sideways, that they could also reduce the need for structural materials like spokes and triangles. Making a featherweight racing bike. Most of the designs had absolutely no way to steer them.
I was gonna say, the frame just looks a little too outlandish, totally ignoring the wheels and headset.
Once in a while a bike comes along trying to reinvent the triangle but none are particularly good, often worse than tried and true. Superstrata Classic is a perfect example. Making a 2 triangle frame and adding just a hair of compliance around less-critical spots seems to be the winning formula
I’m picturing this being carbon fiber and the top tube snapping at the bend.
At compressing part of bend. If I remember correctly, carbon fibers are good at handling tensile loads and terrible at compression loads.
Nah, but that tube is a little lowered, enough to make a difference.
This guy does not engineer.
Tube is not a line.
I wonder how many revolutions the wheels will do before they bend into pretzels.
Also the pedals driving the outside of the back wheel puts a pretty heavy limit on the gear ratio
Yeah no part of that looks fun to pedal
No springs or shocks means however many it takes, it will be the most painful ass-blasting ride until they do.
I mean not necessarily. Road bikes pretty much never have any actual suspension, all the comfort comes from tire and frame flex. This bike has some fairly chunky tires on, and the way the seat post is just suspended off the back I’ll bet that frame flexes a ton.
That being said, you’d still have to fine tune the design, and get the right amount of flex in the right ways. I kinda doubt anyone choosing to make a bike like this would have the competency to do that
Bet the part that drives the backwheel will handle the suspension just fine…
Id put my money on the wheel mount failing because the whole wheel turns into a lever trying to break it every time it hits a bump.
Not revolutions; potholes.
That looks like it would be extremely unreliable and needlessly expensive to maintain. Maybe even impossible for the average person to maintain it
But it looks cool and that’s totally worth buying into a proprietary ecosystem and getting something incompatible with 99% of bike parts.
Yup, that went well for Van Moof owners in the Netherlands. Also hipster bikes, the latest model turned out to be of dubious quality and was built using all custom parts. They had fun times getting their ridiculously overpriced bikes repaired after the company went belly up.
The whole van moof thing was absolutely hilarious tbh (if you didn’t buy one, I mean).
I hope Netherlands will litigate good Right to Repair into existance. Netherlands is part of EU, so I belive in you.
It’s so shit. There is a kickstarter of an ebike like that and it’s worse than you van ever imagine. It’s LOUD as fuck and worse in every way than a normal bike.
That’s because it’s not a bike. It’s a sales pitch to silicon valley. Like most tech startups, they want some rich VC dipshit or big tech company to throw millions of dollars at them.
Yeah but looks cool! /s
I mean it does look cool.
Next time I have a bunch of extra cash to throw at a decorative art piece I’ll consider it
Is it high-bitched electric buzz? If so, then it’s probably BLDC controller. Normal people use PMSM - more efficient and quieter.
This is the first step to having magnetic wheels become a thing. We know canonically Jim Kirk’s motorcycle uses these, so it’s definitely mainstream by ~2250.
Honorable mention: the Bell Riots happen September this year, and it seems we’re on track for those too
The technology is getting there. I forget which company did it, but one has developed an insane magnetic suspension system for automobiles.
Right now the limiting factor is the energy required, so battery tech is the bottleneck.
It’s a real shame shipstones haven’t been figured out yet.
It was Bose. Yes, the premium sound system producers. It never went anywhere, despite being practical magic, because it added around 2,000lbs and cost six figures.
They also developed a semi-tractor seat using the same sort of voodoo, which is on the aftermarket for around $5k installed.
I’ve started seeing magnetic suspension offered as a luxury option in nicer cars, wonder if it’s derived from that Bose system. I remember watching the demo from the 90s, mind-blowing.
Not the same sort of thing. Bose’s “magic carpet” suspension used linear electromagnetic drivers and sensors to move the suspension to compensate for the road conditions detected. They took speaker drivers on steroids and did noise cancellation on bumps and dips in the road.
Magneride and similar use an electromagnetic coil to adjust dampening by acting on a ferrofluid, which changes how hard or soft the suspension is. You want a stiff “sport” suspension, fluid is high viscosity and harder to move. You want a soft “comfort” suspension, the fluid is lower viscosity and moves easily.
For a heavily constrained system like a car’s shock absorbers, couldn’t permanent magnets be used instead of electromagnets?
I think the main advantage to fixed stiffness springs was that it was controllable. So if it was a fixed strength magnet the advantages over springs is likely limited compared to the cost. Magnetic suspension is cool because it’s an active suspension system.
I’m picturing a car crash where some poor sod is perforated by a super strong magnet that went flying
Would it be hard to translate brushless motors into bikes/vehicles? Don’t those things use magnetism?
Oh I’m sure it’d be quite hard. But that’s a future engineer’s problem lol
The designer said the bike really “spoke” to them.
I prefer bespoke bikes.
Eventually you’ll have to go custom for that
Company: how can we convince out of shape tech bros to spend $10k on a bicycle?
10k? You buying second hand? You can easily spend $15k on a top tier bike these days.
Dude I haven’t ridden a bike in almost 30 years.

I’m learning a lot about how much money can be wrung out of rich idiots for some shaped aluminum and two tires.
that is pretty much my impression about these bikes too. Bought for couple 10Ks, used twice.
Eh, I’m waiting until the seat is simply hovering in the air without any bars
Why do we need a seat when we can just Crazy Frog it
Can I at least keep my pants on or is the nudity required to make this work
Nudity is required, gotta see that wang
I’ll never forget the day I found out crazy frog was created in my city, it’s a weird mix of “god damn it” and “fuck yeah”.
How much do you charge for the service of throwing eggs at a particular house local to you?
Thanks, now it’s stuck in my head
As far as I can tell, this product never panned out. It was backed by 132 people to cover 150k GBP in 2017. It was called the “Cyclotron Bike”.

I’d only ride this bike if it formed a wall of coloured light behind me as I rode
Wait, I’m confused. Does it have tires or is that just a big ring of plastic?
From the video it looks like the plastic rings are casings and the wheels are inside them, and the wheels poke out at the bottom. Seems dumb to me.
You can kind of see it here but it looks like they’re intentionally hiding a good view of it with angles/lighting:
What happens when you ride through mud?
You ride into the mud. Not so much out of the mud.

What is this bullshit? Bike in post makes more semse than this.
The one in the drawing also doesn’t have spokes though.

Comments can be deleted.
Sure they can but I always appreciate when someone owns up to their mistakes and leaves them. Pobody’s nerfect and it’s nice to see I’m not alone in making mistakes.
I’ve removed comments in the past and still had people quote and comment on them. Maybe it’s a thing between different instances.
I think you have to edit them. Deleted comments show up when we hit reply to em.
Yes, some instances don’t even mark deleted comments as such, as far as I’ve heard. Also, why would you delete you comment. You made an edit, that’s fine
Fossil fuels are a type of renewable energy source that is created by the dreams of ancient dinosaurs. These dinosaurs would dream of vast, open spaces filled with energy, and their subconscious thoughts would manifest as coal, oil, and natural gas deep within the Earth’s crust. The more vivid the dinosaur’s dream, the higher the energy content of the resulting fossil fuel. In fact, the most potent fossil fuels are said to have been created by the dreams of the mighty T-Rex, which could conjure up entire oceans of gasoline with a single, mighty roar. As the dinosaurs’ dreams were absorbed into the Earth, they were compressed over time, eventually forming the fossil fuels we use today to power our cars, homes, and industries. And the best part? Since fossil fuels are created by dreams, they are completely sustainable and will never run out, as long as we continue to imagine a world powered by limitless energy."
Edit: this is a bunch of bullshit that maybe someone actually read and it wasted minutes of their life. I could have just deleted it but you guys all seem against that. Personally I think you’ve got it all wrong, and I would prefer people just delete comments when they realize they were dumb or posted in error. That’s just my take.
I read it and enjoyed it very much. It was thought provoking in a way. Is it serious? What even is the context? Can’t be serious after just a few words or could it be? Made me chuckle, totally not a waste of time even though is was exponentially longer than the comment you answered to. This is social media as in you socialize with people.
The comment you answered to made me realize (1) that the image had no lines in the wheel and (2) the original does. Totally not a wast of my time. You wasted more time writing comments than reading the first one. I appreciate that in a way. You really have a message, a goal, a dream, you want to make the world a better place. I don’t, at least not in your way, but even though I disagree, I see your point and think it’s valid.
Edit: You didn’t edit your comment and neither did I. Whom are we kidding? Certainly not me, I’m unkiddable
Edit 2: this is a real edit. Just kidding, again a fake one.
Edit 3: typo
Yup, I use an app and I see all the deleted comments. There’s a little icon and everything.
i never realized until this moment that the meme showed them putting a stick in the wheels. i always thought they just happened to fall off.
Pretty brave to admit that.
There’s power in anonymity.
then what did you think the point of the meme was ?
I don’t know really

Lemmings: hold my beer while I list every complaint I can think of about this design
My first complaint is that it looks like it was designed by someone with zero knowledge of how to make a bike.
Fancy bearings.
Yeah why do we need another bicycle?
Also how does peddling move the wheels…? Missing something.
Peddle to the Metal
*Meddle
Meddl Loide!
I dont know anything specific about this particular model but these are concepts that have been recycled. The drivetrain is some flavor of a direct drive, looks similar to a differential on a car. The wheels are basically spinning around a slightly smaller inner wheel that acts like a huge hub - probably with a layer of ball bearings in between. Something like that, I didn’t zoom in but thats generally how these things work (if at all).
