Is the 'shark wheel' a good idea for a bicycle? I recently found a product that is a redesign of the common wheel.  It's branded as the 'shark wheel'.  It's basically a wheel where the rim is circular but bends like a sine wave.  Simple idea but very interesting.

Currently, the company only has skateboard wheels in production.  However, I recently saw the owners give a presentation where they demoed larger wheels for strollers, wagons, etc.  I can't help but wonder how long until someone rigs something like this onto a bicycle hub and rides it.

The stated benefits are that the wheel has, or can have, a thin tire with low rolling resistance but it grips like a fatter tire because of the way in which it travels over the ground, constantly changing velocity.

Below is a picture of one of the wheels.  My question is can this design be applied to a bicycle wheel, and, if so, would it be more performant is certain cases, e.g. off road?
On a skate board type application it is effective 

On a bicycle it is not effective and impractical to implement



On a skate board you want a wide contact patch. On a skate board you absolutely don't want the wheel to tilt.  The idea is to keep the width but reduce contact area.  The reduced contact patch has lower rolling resistance. Within the virtual flat contact surface are circular surfaces that will shed debris (small rocks).  They can also can go with softer material so you give back on rolling resistance but get softer ride and more grip.  They are not taking over the skate board market but they have a niche and it may grow to dominate.  It is more than just a fad with no real value.  And some people  will buy it because it looks cool.

Basically none of that scales to bicycle.


A bicycle leans and as soon as you lean a shark wheel it is no
longer round.
That is a show stopper.
Even if it stayed round on a lean the extra width on a bicycle with comes
at large expense. 
A spoke type design would not work.  Would need a solid wheel.
Would have to be a solid tire.  Pneumatic would push the tire off a curved rim and put stress on the rim.
