The Official Hubless Wheel hater thread.

Mancurians are so weird.

I kind of like this hubless (28 seconds in). Looks like fun. If someone knows how to embed the video, please do so.

Haters!! How are we going to move forward as a species if we keep riding around on spokes and rims? I think the hubless wheel needs something like Clark Griswalds super slick spray bond - as eloquently sampled on the metal snow dish.

But, don’t forget that Franco Sbarro made the hubless wheel cool in the 70’s!

She looks HAPPY!

and here I’m not sure if she’s been run over by it and is STILL happy or is riding with her face IN the wheel or is just posing, but any way you slice it, she’s happy.

AND, his pizza rocks in malls and airports all around the world. :slight_smile:

That counter-shaft sprocket must be huge… . . .

…bringing back this thread too…cause this is so awesome!..

Levitation is an art installation for a prototype bicycle. The concept of the Levitation project is that cycling on the community scale can produce clean, healthy, sustainable energy. This is achieved by an on-board generator and high capacity batteries that store the energy you create during the act of cycling. When you get to where you are going, Levitation has a “drain plug” system that allows you to plug your energy back into the grid. Individually, Levitation is great for powering your mobile devices with free energy on the go. On the community scale, the benefits of Levitation are exponential, from less carbon emissions during commutes, to healthy living, to producing free zero-carbon energy. The HIMACS material is an essential component to the mix, as bicycles of the future become rapid prototyped. The idea of Levitation suggests that anyone can make their own custom ride from color inherent, renewable materials. Why drive when you can Levitate. Live the earth Touchless.

What the hell is going on here? Obviously this person has never been on a race geometry bike for a few hours. No one would want to sit (?) in that position for 2 minutes. But I guess it’s alright, its got USB 3.0. Who needs a seat anyway?

I’ll decide to stop there…Too many things to comment on

Ermm… Hi-Macs is a thermoformable sheet material, nothing to do with rapid prototyping. But bonus points for trying to maximise the use of buzz words.

To everyone who is considering more innovative, novel, never-been-thought-about-much-less-entered-in-a-design-competition, IDEAS - read this first.

"You can’t generate a meaningful amount of electricity with a bicycle, and it won’t save any money, either, because bike power generates such a tiny amount of electricity versus the cost of the setup. And it might not even be green energy, once you consider the energy that’s used to produce your fuel (food).

If you cycle with a power meter, you know that a fairly strenuous ride yields an average of about 140 watts for an hour. Mount your bike to a generator, slice off 30 percent for mechanical and electrical losses, and you’ve put out a measly 100-watt average during your sweaty hour. It amounts to around a penny’s worth of electricity, one three-hundredth of a typical home’s daily use—not enough juice to run the PlayStation for 15 minutes.

If you pedal for an hour a day, 30 days a month, that’s (30 x 100=) 3000 watt-hours, or 3 kWh. That’s less than 1% of what a typical family uses in a month (920 kWH). You generated 0.3% of your energy, and continue to get 99.7% from the grid. Good job.

But how much money did you save? Well, since the average cost of U.S. electricity is 12¢/kWh, that one month of pedaling saved you $0.36. Congratulations. If the system cost $400, it would take only 93 years to pay for itself."

:unamused:

You might be better off just saying “magic”, instead.

If only Physics was a mandatory part of ID curriculum. :wink:

Nothing a perpetual motion machine can’t fix!

I believe this was a competition entry for products using Hi-Macs…sounds like they won’t get very far by not using it in the way it was intended.

Who am I kidding, it will probably win.

And a materials course and they also need to start at Victor Papanek’s “Design for the Real World.” I ride a bike that was assembled in December of 1980. It’s an inch or so too tall for me to get on it comfortably. And the tires are too fat for efficient rolling friction. And it’s scratched. It’s heavy. And it ain’t pretty.

But compared to what these hubless beauties would do for a ride… it’s perfect.

Level Up

What the &^@$ is that?

You win the award. What award, I’m not sure. Its hubless.

Guessing it uses those props to turn the wheels…? Anyone?

Incredible.

Just an RC quadrocopter/car hybrid. I know this is the hubless hater thread but I think it’s a cool way of accomplishing both :wink:

kudos to making a working model (the video on the kickstarter), but I couldn’t shake the suspicion that strings are involved

Good Pics…

I think that’s just a product of poor controlling software. Looks like there’s no gyro sensors for stability, and I think he’s manually balancing the speed to hover. I had similar results flying a cheap RC helicopter.

Video of a better control system for comparison:

GMP Cricket cheap?

As Seen on TV Store cheap :stuck_out_tongue:

The Cricket looks pretty awesome though, spent some time looking through forums and engine specs. Do you know how long they can go on a tank of gas?
