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?
