Company: his can we convince out of shape tech bros to spend $10k on a bicycle?
that is pretty much my impression about these bikes too. Bought for couple 10Ks, used twice.
Only 10k for full suspension futuristic looking bike, that’s a bargain tbh :D
You mean 0 suspension?
Don’t get me wrong, I’m not saying this is good, I’m just saying that bike industry is so insane that 10k for a bike wouldn’t raise any eyebrows.
I’m learning a lot about how much money can be wrung out of rich idiots for some shaped aluminum and two tires.
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.
Nah; you just have to jam the stick through the tire itself so it gets caught at the part that is spinning the wheel.
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 ?
One of today’s 10000?
I wonder how many times someone has learned something new and then the first reply they read was a link to that comic and they discovered that, too?
I don’t know really
okay :-)
You know there’s a relavent XKCD.
Then send it
I haven’t clicked it. One of the 10 thousand?
Yep
Yeah why do we need another bicycle?
Also how does peddling move the wheels…? Missing something.
Peddling never moves the wheels.
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).
I wonder how many revolutions the wheels will do before they bend into pretzels.
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.
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…
Not revolutions; potholes.
The designer said the bike really “spoke” to them.
I prefer bespoke bikes.
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

Oh I’m sure it’d be quite hard. But that’s a future engineer’s problem lol
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’m picturing a car crash where some poor sod is perforated by a super strong magnet that went flying
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.
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!
Right? Who would be crazy enough to do that?
Next you’re going to tell me someone will make one without a top tube?
doesn’t that prove their point? they all look overbuilt, as the original commenter said.
Carbon fiber, aerodynamics…
This one is use as suspension
Not that rare in old mountain bikes either, pretty sure my old Raleigh was similar
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
Eh…
Modern mountain bikes? Hell, they make car and motorcycle wheels out of it…
I Googled “motorcycle carbon fiber wheel” and autocomplete immediately suggested adding “failure” and doing that search has endless relevant results
And if I do a research for “Toyota Tercel engine failure” I find tons of results as well even though it’s one of the most reliable car ever built.
Crazy how search engines show you results for what you’re looking for, right?
That top one is kinda sexy ngl
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.
I still showed that it’s perfectly possible to build a bike without a seat tube, hell I’m sure we can find 90s examples that weren’t high performance bikes.
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.
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
Nah, but that tube is a little lowered, enough to make a difference.
This guy does not engineer.
I’m picturing this being carbon fiber and the top tube snapping at the bend.
I don’t think this will work on the long run.
First, the hold on the rim must be very tight and precise or the wheel will wobble like mad.
Second, such a tight hold will be very sensitive to any kind of dirt, so it has to be sealed.
Any seal tight enough to keep extremely small dirt out will cause loads of friction.
Tight seals in general is not an option, they exist en masse with e.g. hydraulic cylinders. But for them, the friction is basically a non-issue in comparison to the overall power budget. But I cannot imagine an even halfway free wheeling wheel that will not break down after getting in contact with a bit of sand.
Me on that bike: ah, muddy dirt road, my arc nemesis. And what’s that? a random pile of dog poop, my day’s ruiner.
Ok, maybe with a magnetic linear drive?
Is this an AI bicycle or a Dyson bicycle?
I suppose either way it sucks.
Dyson also makes hand dryers.
They blow.
And very very expensive.
The one in the drawing also doesn’t have spokes though.
[edit] Edit don’t reply I didn’t notice the drawing was modified.
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.
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
I think you have to edit them. Deleted comments show up when we hit reply to em.
Yup, I use an app and I see all the deleted comments. There’s a little icon and everything.
Needs blue or orange neon lights
The wheels are apparently really really loud when they are mounted like this. You just can make good enough ball bearings of this size at any reasonable cost and weight
