A bicycle for rotary fans - or have we already talked about this?

Rotary Bicycle Wheels

In reply to No Time :

It took me until the end of the vid to actually understand how they work. I wonder what the fenders are made of? Hopefully something slick. 

Looks like the undersides of the "fenders" are blocks of teflon, which I would think is the best choice. It would be a good idea to have a tire spray system to help clear grit from the "fenders."

Edit: I'd think a more efficient if more complicated mechanism would be to have each wheel chain-drive a crank & rod mechanism that moves the suspension up and down.

“The triangular wheels are the equivalent of riding a normal bike up a 12% grade”

As an engineer I'm scratching my head as to why? It slow, inefficient, and in no way an improvement on any existing idea. The only positive I can add is it's different than anything I've seen. Just because you can do something doesn't mean you should.

Interesting proof of concept, but...

In reply to D2W :

It might be easier to rid up curbs, if you It it with the wheel in the correct position? 

In reply to GameboyRMH :

That’s exactly what I was expecting & I kept replaying the first part of the vid looking for one. 

The man should work for BMW. He is obviously a master at complication for the sake of complication. 

Not better. Just more parts.

For the lulz, that's why

I believe he made it to take to burning man, so practicality or clear purpose is not necessarily a requirement. 

makes me think of the square skateboard wheels that i see pop up from time to time.

What. The. berkeley.

Why?!?!?!?

It's actually just an optical illusion that makes these look square, if you measure their diameter you'll find that it's as constant at any angle as any regular skateboard wheel.

These wheels actually have a practical use - they skitter left and right over pavement irregularities, instead of getting caught on them.

This generally applies to most of the contraptions ridden/driven around at Burning Man... complication for the sake of "art"...
