Reinventing the wheel?
All criticism aside, the custom color combinations and variable durometers are intriguing. I'll give 'em that.
But wait, there's more! From the kickstarter:
We plan on going into every market with a wheel. It is just a matter of time and money. From military vehicles to bicycles to wheelchairs, we want the Shark Wheel to be identified as the only non-circular wheel in existence.
Can anyone tell me what the Shark Wheel friction and rolling resistance coefficients are? Compared to a standard wheel made from the same material as the Shark Wheel? Wheel chair, luggage, sprinkler system fork lift and other wheels are slow motion wheels compared to skate board, bicycle, automobile and aircraft tires - very slow! If the force needed to use those slow motion wheels were appreciably reduced, it would conserve energy and lower costs.

They work great! And they are fun. That's what skateboarding is about. Fun! Go cram your stuffed shirt B.S.. They have sales all the time I paid $36 for a set shipping included

Alternative wheel concept

Despite everything said above, I bought a set off Amazon. They arent quivker than my Aussi Penny Longboard wheels but and I used them on the penny longboard trucks. However, i can confirm, and argue if u want, but i can confirm that they make riding way smoother and sliding is alot easier. They are expensibe though so I recommend that u only buy them if u live in an area with crappy pavements or trees with nuts ie oak, horse chestnut. Because it isnt worth the money if ur just wanting to use ur board for getting around. Good for cruising long distances though

Sheesh, haven't you ever heard of the null hypothesis? The onus is on the one making the claim, against all available evidence, to prove their position. By your logic, God must be real because it is impossible to prove that he isn't. All one needs to do to make a claim that can't be disproved, and by your logic, that claim should be granted legitimacy solely on the basis that it's not completely impossible.
Are you following?

It's a round wheel with an unusual treat pattern. Nothing else.

Your comment is as silly as their claims. Sheep. Go buy some of these cubic scams.

Nothing but marketing hype and lies. You should be ashamed of your claims.

And this is why people make money off of simpletons. Yeah, I did not invent it but that does not make it work. It is a GIMMICK. Try using these on a bike and lean into a turn. I GUARANTEE you will fall off the bike.

It is a same design as "wave washer" i can create that shape with simple formula in almost any CAD system. How can this be patented if it is that obvious?

Have you idiots maybe thought that they didn't do any scientific tests because they don't want to show how it works yet until they get all there patents or they could have a chance of getting ripped off..

I am a lifelong skater, and met this guy on Venice Beach, Ca. I was fortunate enough to be able to test them in person when they debuted the technology at an Abbot Kenny Blvd. festival. Despite all the negative comments above from people who have obviously NOT tried these things, I can attest to the fact that this wheel design is far superior to the normal (round) wheels. At least for certain activities. They ride easier, smoother, faster. When you put the same set of bearings in a round wheel, with similar softness and diameter you can drastically tell the difference. You can push yourself along using far less energy, you don't feel the bumps in the road. If they weren't so expensive, everyone would be riding them. Try it before you knock it.

Oh man...this conversation is gold! Don't stop now! :D

All the bikes with their racing wheels came in last place in the race.

Anonymous I FULY AGREE WITH YOUR POINT: "...(they) are just slamming them because (they) did not invent it. They also make racing wheels for bikes." Edited for clarity.
(DOUBTFUL this will pass the censors review).

APPROVAL? So only comments that agree with an author are approved? It figures. The puritanical folks must first grab the bible and ask the 'Lard' if comments fully agree with the garbage the 'expert' spews!
NO HOPE of the TRUTH ever appearing here; none at all. I'm outta here!

NOBODY has shown PROOF POSITIVE the "wheels" do NOT perform as claimed. All I have read thus far is the POSSIBILITY the wheel is not an improvement of the circular wheel. HALFSTACHE'S line, "To agree with one of the developers' dodgy claims," is just as "dodgy"and offers NOTHING to substantiate his claim of the wheel being bogus. JEALOUSLY (HE COULD NOT DESIGN SUCH A 'WHEEL') seems to be the ONLY point made in this biased article. I don't care about the claimed qualifications HALFSTACHE offeres; on THIS ONE he is full of crap.

No offense but I have a PhD in physics and a lot of what you say is completely incorrect. For that reason, I would never use your product.
Friday, May 15, 2015 at 8:24 PM
has anyone devised test protocols to test these claims?
Wednesday, October 22, 2014 at 2:42 PM
Well the basic claim that less contact area has less friction is total BS, so the whole premise is faulty. There is an ideal contact patch for each situation - surface, wheel durometer, rider weight - and too little contact patch will be much slower, as will too much contact patch. Try it yourself - shave down a decent set of longboard skateboard wheels to be much narrower - they will be much slower. Similarly a set of very good inline skate wheels put on a skateboard will be slower than skateboard wheels of the same diameter and urethane, because the contact patch is too narrow.

use a higher quality ball bearing between your board and wheel and u have the same effect

Have any of you actually ridden one? I don't know about physics but I rode one today and it definitely feels faster than my 70mm long board wheels of the same durometer.

"David Patrick" above (October 16, 2013 at 5:15 PM) counts out the six benefits of Shark Wheels as: 1, 2, 3, 3, 4, 4.

Oh wow. What a surprise you immediately bring up 9/11

I'm not going to withhold judgement.
There's zero real physics demonstrated in the videos. No tests. And they are not cubes. The only thing they might do is give you more traction because they have increased area and varied angles for grip. It's vaguely possible that the wheels may be faster on perfectly smooth surfaces due to reduced contact area. Big deal, nobody is trying to shave three tenths of a second off their track time.
It doesn't hold up to scrutiny. Enjoy your novelty wheels, I hope you feel faster and "grippier." I'd be caught dead buying them.
