Fancy bearings.
Ok, maybe with a magnetic linear drive?
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

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).
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
Yup, I use an app and I see all the deleted comments. There’s a little icon and everything.
I think you have to edit them. Deleted comments show up when we hit reply to em.
Is there any regime where this is more efficient than spokes? I’d imagine that at high speed there’s an aerodynamic advantage (possibly similar to a track/TT disk wheel?), but I can’t imagine the bearings being better than current bikes. But bearing loss might (???) just scale linear with speed, so probably a win from aero in the end. But this isn’t counting weight, which I imagine is worse (but doesn’t matter much at high speed on flat ground).
Is looking cool important?
In cycling? Super duper important.
Broke: How many times will I need to repair this bike over a lifetime of ownership?
Woke: How many people will stare at me as I’m biking?
Bespoke: How many times will this bike get me laid?
For the last one it’s more competitive than you think. I’ve gotten laid thanks to a bike people didn’t even see. Gets you an ass that does wondets
Yes. The answer to that is yes. Especially for a render
*The coolest looking concept bike ever created.
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.
That looks like it would be extremely unreliable and needlessly expensive to maintain. Maybe even impossible for the average person to maintain it

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 rediciously 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.
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
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.
Is it high-bitched electric buzz? If so, then it’s probably BLDC controller. Normal people use PMSM - more efficient and quieter.
The designer said the bike really “spoke” to them.
I prefer bespoke bikes.
May as well be. Gotta dumb down all the other facets of society as it is
Not exactly dumbing down, I guess removing components which are redundant after redesigns
Highly depends on the use case. I doubt this type of construction would work with mountain bikes (or at all, honestly, since the design for this is very old by now and it clearly never went anywhere).
Well yeah, different bikes require different designs
Unless they’re two different bikes with the same design
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.
Nah; you just have to jam the stick through the tire itself so it gets caught at the part that is spinning the wheel.
You could also cover the spokes or use a spokeless single wall design. I do think a design like this would need to be cleaned a lot.
just curious how strong would the fork have to be to handle the forces…
Fork aside, a bike wheel’s structure is based on supporting the load on the hub by hanging from the spokes at the top of the wheel. In order for that machine’s wheels to not fold in half the rim would have to be incredibly heavy and slow.
Now that you mention it… This doesn’t look like it would actually work once a human being is actually on it. All the weight is gonna be on the tires and the part holding (and presumably spinning) the tires. Also: What the hell are the pedals connected to?
There could be an internal chain between the pedals and the rear wheel, but that’s going to be a single speed and suuuuuck to ride.
Idk, hahaha. I mean the torque applied to the axle would be huge so either that shit is Adamantium or it breaks
Never mind how strong the thing itself is, that joint is basically impossible to engineer so that the wheel can’t rotate side to side. That is, rotate on an axis it’s not supposed to. Sure, you can prevent an (essentially) round thing from rotating with a pipe clamp, but now try to do that while allowing freedom lengthwise.
That wheels are round and not pipes help a bit, there’s some lever purchase you get from the radius but in general, nope. You’re still sitting at the short end of the lever.
Diamond frames with spoked wheels are literally the optimal solution to the problem the rest is compromise (e.g. having no top bar for comfort) or overengineering.
I wonder how many revolutions the wheels will do before they bend into pretzels.
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.
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
