We Reinvented the Wheel. Literally.

Invest in Shark Wheel

Why reinvent the wheel?  For 5,000 years the wheel has been the go-to design for most types of transportation. In fact, no one considered there could be a better design. The circular wheel was always considered the final design with no room for improvement.

Enter Shark Wheel inventor, David Patrick, who refused to accept the status quo. Not only did David create a shape that was drastically different, but he envisioned the shape possessing inherent advantages built into it. His search to improving the wheel was an uphill battle against industries that were not used to change.  He needed to prove his idea was revolutionary.

I met David through my tennis coach who thought I could help him build a business around his invention.  As a former professional tennis player on the ATP Tour for 10 years, I was no stranger to hard work, long hours, and relentless determination. I immediately saw the vast opportunity in joining forces with David to help bring the sine wave wheel to life. I imagined a skateboard company introducing a new wheel where the skater is safer going over debris and other rough terrain. I imagined a farmer whose tractor creates unwanted trenches in the field and being able to help that farmer save money and not dig a trench with our wheels. I imagined a wheelchair user having the freedom to go more places without rough terrain standing in their way. 

Shark Wheel is a company located in Lake Forest, California dedicated to making the most unique, innovative and technologically advanced wheels in the marketplace. The Shark Wheel is flat on six sides and displays many scientifically proven advantages compared to the traditional wheel. Having won multiple international competitions in the skateboarding industry, the Shark Wheel has proven to be a high-performance product. 

The patent pending Shark Wheel is a perfect fit for transportation use including wheelchairs, strollers, wagons, farming equipment, military applications, ATV vehicles, shopping carts, tricycles, hand trucks, printers, toys, iv poles, casters, roller skates, luggage, forklifts, office chairs, wagons, vacuums, hospital beds, ambulance cots, other medical equipment and much more. Please see our Shark Wheel Industrial Products section below to learn more.

I am a passionate entrepreneur whose mission is to enhance mobility and make lives better.  I invite you to join my mission, become a part of the company, and join the revolution that is Shark Wheel. Help us reinvent the wheel and together we will change the future of transportation.

Shark Wheel Company Structure

Company Structure

Shark Wheel Inc is the parent company that holds patents. There is currently one subsidiary that operates underneath called Shark Wheel Skate LLC. All investors will take ownership in the parent company and be a part of every wheel market Shark Wheel ever enters into. Investors will own Shark Wheel Skate and any other subsidiaries that may be created in the future.

Currently, the most likely scenario is to sell pieces of the company. For example, Shark Wheel could sell the rights for its stroller application and receive a large cash sum. But, Shark Wheel would still own 99% of the other markets it wishes to pursue. 

Conversion of Company to Delaware C-Corp

Shark Wheel just converted to a Delaware C-Corp (from a California LLC)  

One of the biggest advantages of the conversion is that it allows Shark Wheel to take advantage of IRS Code 1202.  The conversion starts a 5 year clock that allows Shark Wheel to sell the entire company and allows for profits to be tax free for all investors.

Ten Current Industrial Products

Below is a list of industries, with company names omitted for disclosure purposes, that Shark Wheel is actively developing wheels for. Shark Wheel is working with the #1 company in various industries, including a Fortune 500 company. 

1. Luggage

Signed licensing deal. Smart luggage under the SkyValet brand and under the Harley Davidson brand launched October 2018. 

Our SkyValet luggage is selling here currently, with tens of thousands of units already purchased by distributors outside of this campaign.

SkyValet Features:

  • Shark Wheels for swiveling, rough terrain and light weight
  • Charge your phone with USB ports
  • Double zipper for enhanced security
  • GPS tracking - no more lost bags
  • Magnetic openings for quick openings
  • Built-in scale to prevent overage fees
  • Controlled by an app on your cell phone

Also, our Harley Davidson luggage is selling now at Harley Davidson dealers across the United States and here as well.

The most recent to launch is Samsonite golf luggage. Shark Wheel always looks to establish itself with industry leaders. To be associated with the Samsonite brand name that is #1 in the industry is the start of many things to come.

Shark Wheel is in deep negotiations with an industry-leading luggage company after 6 months of successful testing and another large brand as well. Shark Wheel's luggage line will expand significantly in 2019.

2. Central Pivot Irrigation (Farming)

Shark Wheel won a government grant through the National Science Foundation in January 2018 . The grant was for $225,000 to develop a state-of-the-art wheel for the central pivot irrigation industry.  After performing extensive customer discovery interviews and graduating through the government's I-Corps program, Shark Wheel learned what the market desires in a wheel:

  • Minimize rutting (the industry's largest issue is digging a trench)
  • Non-pneumatic tire that can never go flat
  • Modular design that makes maintenance easier and more cost-effective
  • Enough traction to traverse clay-based and sand-based soils
  • Priced with the current industry sweet spot

Shark Wheel hired a company that builds wheels for the Canadian Space Agency to act as a consultant on the project. Together we collaborated on the conceptualization of a wheel never-before-imagined. We are proud to say we spent several months designing, building and testing the wheel and had a very successful test that showed significant advantages over the current best wheels in the market. Shark Wheel filed a patent for this wheel and has applied for Phase II of the grant, which is worth $750,000. The money is used to bring the wheel to commercialization and begin selling it across the entire industry. Shark Wheel has been notified that it will be awarded the $750,000 award (pending audit review) once the government shutdown ends.

Shark Wheel already has a signed licensing deal with one company in the industry and two LOIs with industry leaders.

Retail prices are over $1,000 per wheel. Early estimated annual revenue $10+ million per year. This is a very rough assumption based on current data of selling over 16,000 wheels annually comparable to the leading technologies in the market.

Want to Read the Technical Part?

The Shark Wheel is named after the shape of shark jaws and through many iterations, Shark Wheel created another biomimetic design for its tire based on the shape of seagull wings. The flexing non-pneumatic, modular lugs of the tire design approximated the flotation of a pneumatic tire. The sine wave shape of the Shark Wheel was placed in the standard tandem configuration on central pivot irrigation machines and the result was a wheel that did not go over the same track as the wheel in front of it. The front wheel moved left-right-left, while the rear wheel moved right-left-right effectively creating a helix shape in the soil. In contrast to a traditional wheel that continues to move along the same track over and over again digging a rut, the Shark Wheel disrupted the soil in a snake-like shape, while the rear wheel pushed the soil back to where it began. This greatly minimized the industry-wide issue of rutting. Shark Wheel estimates an average farmer can save over $27,000 by switching to a sine wave wheel geometry because of less down time due to flat tires, less rutting and greater crop yield.

3. Pallet Jack/Forklift/Material Handling

Imminent deal expected for 2019 launch. Deep negotiations for a Q1/Q2 2019 release with an industry leader. Nearly 3 years of extensive testing has graduated Shark Wheel to the precipice of a signed deal. Shark Wheel's team flew out to the company's headquarters to finalize deal terms. Shark Wheel has signed an agreement pending customer acceptance testing. The first customer acceptance test has come back from a company in the top 50 on the Fortune 500 list. Their wheels typically last between 50hrs-60hrs of use. The Shark Wheels lasted 90hrs. This test was a wild success and has moved the deal along swiftly. Per the contract, a deal is to be signed no later than February 28, 2019 if customer gives acceptance. Shark Wheel is in constant contact with the company's marketing department to assist in a creative release into the market.

Shark Wheel has already filed a patent for this particular design in the material handling industry.

Shark Wheel has been offered 4 deals and is currently in negotiations. This is a multi-million dollar deal that will reach the market in 2019.


4. Manual & Powered Wheelchairs

Shark Wheel believes it has reached the final design (not shown here so right to patent is not violated) and the wheel is currently being tested by an industry leader. Shark Wheel is in development on the front wheels for wheelchairs, which is the first point of contact for the wheelchair user.

Industry leader will begin testing soon for a 2019 launch. Initial tests show ability to traverse rough terrain and ability to swivel better than traditional circular wheels.

Developing wheel with one of the industry leaders. Licensing deal at 8%. Early estimates from our partner in this industry at 225,000 wheels in year one.

5. Ambulance Cots

Developing wheel with one of the industry leaders. Licensing deal. Prototype version 1.0 complete, currently going through testing.  

Current ambulance cots have issues going over sand at the beach and traversing other unfavorable terrain. The Shark Wheel is considered an off-road wheel and performs best in challenging environments. 

In the medical industry, Shark Wheel has opted to seek a licensing opportunity. Shark Wheel is not interested in manufacturing in this industry and dealing with strict regulations and testing procedures.

6. Hospital Beds

Developing wheel with one of the industry leaders. Licensing deal.

As mentioned above, in the medical industry, Shark Wheel has opted to seek a licensing opportunity. Shark Wheel is not interested in manufacturing in this industry and dealing with strict regulations and testing procedures.

The pictures of the carts below show our longboard wheel's conversion into a caster for the farrier industry. Heavy-duty metal casters are in development, but are not shown below.

9. Office Chairs

Developing wheel for one of the industry leaders. The goal is to:

  • Eliminate need for office chair mat
  • Swivel better
  • Traverse carpet more efficiently

Early stages of development, estimated 2020 release.

10. Roller Skates

Just finalized wheel design and will be going into production soon. Now accepting orders from retailers for a kids line and a soon-to-be-developed adult line of skates.

Advantages are similar to what is found in the skateboarding industry:

  • Less friction
  • Tends to physically push small objects out of the way
  • Better over all terrains
  • Smoother ride

Shark Wheel has been fortunate enough to be overwhelmed with opportunity. After airing on Shark Tank and the Discovery Channel, the company has been inundated with requests from industry leaders to develop a Shark Wheel for their industry. They are not only interested in differentiation, they are eager to have a better performing product that will increase their market share. Shark Wheel seeks investment funds to expedite entry into a wide array of industries and to begin work with other companies that are waiting in line.

Design & Advantages

Skinny Footprint / Wide Profile

The Shark Wheel has the benefits of a thin wheel and a wide wheel in one shape. The infographic seen here shows how the Shark Wheel has the skinny footprint of the thin wheel combined with the wide profile of the large wheel.

Thin circular wheels

Low friction, fast, maneuverable, easy to swivel.

Wide circular wheels:

Off-road ability, load-capacity, lateral grip, longevity.

Shark Wheels:

Low friction, fast, maneuverable, easy to swivel.

Off-road ability, load-capacity, lateral grip, longevity.

Industrial Wheel Advantage

Heat - Failure Points

Wheels typically fail in industrial sectors due to heat. Whether its friction, load, or an embedded nail, the failure points become heat-related. Shark Wheels have built-in heat vents that allow heat to escape. A traditional wheel attempts to steamroll over objects - this allows for small objects to become embedded into the wheel and for additional friction and therefore heat to build up leading to failure. Shark Wheel's natural design allows for heat to escape, thereby increasing the life of the wheel. Shark Wheel is in final negotiations with an industry leader in the material handling industry on a multi-million dollar deal.

Military Advantages

Aquatic Ability

Amphibious vehicles do not receive propulsion from their wheels. Shark Wheels aim to change that. Traditional wheels simply spin in water and do not provide any forward thrust. Shark Wheel's natural design digs into the water left and right, much like a freestyle swimmer. The alternating movements of the wheel would create the first amphibious vehicle capable of wheel propulsion. This is just one example of many for a Shark Wheel military application. This is a future application Shark Wheel would like to build with the aid of grant funding for the Department of Defense, DARPA, or another government agency.

Shark Wheel World Champions

Use of Funds

Shark Wheel Industrial and Recreational Products

Although there appears to be a countless variety of wheels in the world, many markets overlap. For example, once we finish the development of the wheelchair wheel we will be able to sign licensing deals for wheelchairs, casters, lawnmowers, hospital beds, strollers and numerous other markets. They all use the same wheel. Investment funds will immediately be used to accelerate the development of wheels across industries.  The future of the company lies in exploiting our patent into as many markets as possible. This is the primary use of funds. 

Shark Wheel was placed in an 800 store test with Walmart in 2018. The first shipment to 400 stores was in the Spring. Walmart completely sold through over 4,000 skateboards by the Summer. The next 4,000+ skateboards were placed into another 400 stores for the holiday season. Shark Wheel sold through 62% of its stock over the Black Friday weekend. We are expecting to be in approximately 4,000 Walmart stores in 2019 and are awaiting a purchase order for nearly 30,000 skateboards soon. Funds will be used to fulfill this order.

Shark Wheel prototyped and is currently taking purchase orders for wagons. Most people are familiar with the two hot-selling wagons in the market - the foldable wagon and the foldable beach wagon. Funds will be used to build the production molds.

Purchase Orders and Molds

Shark Wheel just received over $200,000 in purchase orders. Another $500,000 in orders is expected in the next few months. To fund these purchase orders, Shark Wheel must place deposits. The large companies placing these orders ask for terms. Shark Wheel must be financially healthy enough to finance hundreds of thousands of dollars in orders. While this is a great 'problem' to have, the situation will only escalate in Q2 2019 when massive purchase orders are placed for our pallet jack wheels.

Molds must be paid for in advance of production and molds can cost upwards of $500 each. 100 molds are requested by each manufacture to bring our cost-per-wheel price down and to streamline the production process. That is $50,000 worth of molds every time we go into production on a new wheel. Some of our partners will be paying for the molds per our deal terms, but some will not. The aforementioned material handling industry multi-million dollar deal is with a company (cannot name per NDA) that will be paying the bill for Shark Wheel molds.

Filling these large purchase orders will be easy to do once we get a few completed. We will have enough money in the bank to fund these endeavors purely off of profits. We are setting up meetings with banks now to fund these orders in the interim.

Government Grants

Shark Wheel has been successful obtaining grants to date. Shark Wheel has won 3 out of 4 grants it has applied for and believes it is a good business decision to seek more grant opportunities. 

The following is a list of awarded grants, grants in process and grants coming soon:

  • FedEx Nationwide Small Business Grant Winner, 2015
  • SBIR National Science Foundation Phase I grant ($225,000). Won in January 2018. (partnered with major company we cannot name per our NDA)

  • CalSEED grant. Coming soon

Shark Wheel Strategy - The Domino Effect


Shark Wheel has primarily been a Research and Development company since 2014. Entering the skateboarding industry was the ‘low-hanging-fruit’. It was a market with a low barrier to entry, a market in which consumers purchased wheels as a standalone item, and a market to act as a proof of concept. Shark Wheel proved the interest in the market and that the wheel is truly high-performance by winning several international competitions. Entering the skateboarding industry was also a way for Shark Wheel to pay the bills early on. Initially, it was a necessity for Shark Wheel to prototype various wheel sizes in different industries. There was much to learn about how a sine wave shaped wheel works under load, while swiveling, with different amplitudes and frequencies, and in various sizes and iterations. Shark Wheel had to prove though scientific testing and real-world testing that the shape worked well and using certain factors, outperformed the circular wheel.

Completed Product

Shark Wheel has completed products for skateboard wheels, longboard wheels, luggage wheels and pallet jack wheels. Shark Wheel plans to extrapolate its current designs to enter other similar industries. There will not be a need to continue prototyping any further for these congruent uses. For example, now that Shark Wheel completed its luggage wheel, it feels confident it can immediately license its technology to an office chair company without the need for further prototyping. The wheels in these industries are very similar and Shark Wheel plans to sign paperwork with all conceivable industries that would use an approximate 58mm wheel in a similar configuration. Even industries that scale up or down the size of the wheel in a similar configuration would work as well. Shark Wheel plans to sign licensing deals with scooter companies and other industries that use wheels similar to skateboard wheels. There would be no delay here either, as the design is considered final. No further prototyping is necessary.

The same can be said for pallet jack wheels. Any industrial application that uses a remotely similar wheel is ready for market with a Shark Wheel. The markets are vast in the industrial sector. Once Shark Wheel finishes prototyping its ambulance cot wheel, the market possibilities open up greatly. Dozens of industries use this particular configuration and Shark Wheel plans to exploit the completed design in as many industries as possible, as quickly as possible.

Domino Effect

There appears to be countless markets that use a wheel. In fact, there are over 100 products in the industrial sector alone. It is important to note that Shark Wheel does not need to prototype for each use. As explained above, once key wheel sizes and/or configurations are prototyped a flood gate of markets opens for licensing deals. It is difficult to forecast Shark Wheel’s revenue with any accuracy because licensing deals are expected to fall like dominos once each key wheel size is complete. The initial four wheel configurations are complete. Additionally, once the public sees the Shark Wheel on the many products about to reach the market, other companies will move swiftly to add the cutting-edge technology to their product line. Shark Wheel believes it is on the precipice of an explosion.


Shark Wheel will not have large capital requirements using this strategy. It will primarily be a licensing entity. The following list is a summary of Shark Wheel’s strategy moving forward.


  • Skateboarding and roller skating are the only markets that Shark Wheel will build a brand, manufacture and warehouse inventory.

Licensing Agreements

  • Shark Wheel will license its technology to the vast majority of industries.
  • Shark Wheel will license to companies that have specific testing requirements.
  • One example is the ambulance cot company (name withheld for disclosure purposes). They requires high-level medical testing equipment and Shark Wheel will not do any forms of additional testing.
  • Markets in which the wheel is assembled at the same factory as the final product.
  • One example is Athalon (name included because deal is signed). Athalon has already put Shark Wheels on Harley Davidson, Samsonite and SkyValet branded luggage.
  • Industries that do not have a replacement wheel market.
  • One example is strollers. Consumers do not replace their stroller wheels.
  • Shark Wheel will license its technology to companies


  • Shark Wheel will only manufacture under certain conditions.
  • Each company must agree to warehouse Shark Wheel’s manufactured product in order for Shark Wheel to sign a Master Supply Agreement.
  • Shark Wheel will not obtain large facilities to warehouse large amounts of inventory.
  • Shark Wheel aims to work primarily with #1 or #2 in each market and sign an exclusive agreement.
  • Shark Wheel will determine on a case-by-case basis if it is more advantageous to manufacture or license.
  • Shark Wheel will arrange terms with the manufacturer so Shark Wheel does not need to float funds for inventory purchases.

Scientific Product Testing

Test I - San Diego State University


The Shark Wheel has been scientifically tested at the San Diego State University Mechanical Engineering Department. 

In apples-to-apples testing, The Shark Wheel was found to have a 15% longevity and 15% speed advantage. Also, frictional tests were performed and some of the data is seen below showing a significant advantage compared to a traditional wheel.

Testing Equipment

Tests were performed and the testing rig (seen above) was designed and constructed by a team of engineering students at San Diego University, Mechanical Engineering Department. Testing has been completed as of December 2017.

The dynamic testing outlined in the following report was conducted at approximately 720rpms(17mph).

Conclusion Test I

At a load of 30lbs the Shark Wheel demonstrated an average of 35.52% less rolling resistance at speeds ranging from 0-650rpms (approx.  15.5mph).
When loaded to 45lbs (per wheel) the Shark Wheel demonstrated 60.92% less rolling resistance.

Rolling resistance, also called rolling friction, is an important factor in many industries.

Test II - Conducted by Major Wheel Manufacturer

Another scientific test done by the largest skateboard wheel manufacturer in the world. They compared Shark Wheel to the leading wheels in the market in an apples-to-apples test. Same diameter, same durometer (hardness), same material.

Conclusion Test II

The Shark Wheel showed a 15% rebound advantage. Rebound translates directly to speed. In the abrasion resistance test, Shark Wheel demonstrated a significant advantage as well. The lower the number in the abrasion resistance graph, the better it performed.

Additional Testing

In separate testing at a Canadian test facility, the Shark Wheel exhibited a longevity/wear advantage.

Tests performed by the German tv show, Galileo (similar to the Discovery Channel), found advantages in rolling resistance and off-road performance. The episode aired in December 2016.

Most recently, our material handling industry partner (pallet jacks, forklifts), completed 3 years of scientific testing and customer acceptance testing with a Fortune 50 company. Scientific testing showed a maximum of 600% longevity advantage (3 years of testing) and a real world test of 200% advantage.

Company History

The Shark Wheel was invented by David Patrick. The sine wave shape was a repeating pattern that David discovered all throughout nature and is nature's preferred choice of motion. The sine wave can be seen in how snakes slither, fish and sharks swim, how the planets rotate around the sun, and even how humans walk with an alternating gait. The Shark Wheel name came from the wheel's identical shape to a shark's jaw (picture seen near top of campaign). 

Shark Wheel launched through a Kickstarter campaign in June of 2013. Shark Wheel’s fundraising goal of $10,000 was reached in 72hrs, finishing with $79,300 in a 30 day run. After the successful campaign, it took the company 7 months to solve the molding issues that prevented mass production. It was one thing to reinvent the wheel, then the company had to reinvent the mold, which is now patent pending. 

Shark Wheel is able to pay the same price per wheel as any other wheel company. There is no price penalty or time penalty for any company choosing to use Shark Wheel products. For a company to violate Shark Wheel’s patent and produce Shark Wheels in mass production successfully would be a massive undertaking that would prevent any copycat manufacturers.

Patents and Trademarks

Shark Wheel has issued patents in the United States and China. Shark Wheel is patent pending in over 30 countries. Investment funds will be used to continue to strengthen the patent portfolio. Funds will also be used to file more patents for new innovations and iterations. The inventor and CTO, David Patrick, already has next-generation versions of the Shark Wheel ready to be patented. Before prototyping and release, the first course of action would be filing a patent to achieve a patent pending status. Shark Wheel version 2.0 patent will be filed with investment funds. Pictures are not available at this time, as version 2.0 pictures released publicly before the filing date would violate the right to patent.

Shark Wheel already has one issued trademark in the United States and one in China for skateboard and roller skate wheels. Other trademarks are pending in many industries including forklifts, pallet jacks, medical equipment, wheelchairs and others.

2018 patent filings: 

  • Filed for a farming wheel patent
  • Filed for a luggage wheel patent
  • Filed for a pallet jack/materials handling industry patent

Season Finale Sneak Peek: Reinventing the Wheel

David Patrick and Zack Fleishman of Shark Wheel claim they've reinvented the wheel -- seriously. They say their version rolls faster with more grip.

This Guy Reinvented the Wheel ... by Turning It Into a Cubecle Here

What's better at being a wheel than ... a wheel? That is not a rhetorical question or a Zen kōan or the start to an awesome joke (sorry). Inventor David Patrick, an avid skateboarder, stumbled (or, you know, skated) onto a way to reinvent the wheel as something that he claims is better than the tradition cylindrical model -- something faster, more stable, and more ground-gripping. Its inspiration, Patrick says, "came from a cube." He calls his creation the "SharkWheel," and he has patented the invention

COO of Shark Wheel: Zack Fleishman

Sometimes the world of business can be like shark infested waters. It can be highly competitive with fierce ambition of budding entrepreneurs seeking success. Our newest Business Leader has proven that with hard work, unrelenting tenacity, and faith in ones product, one really can re-invent the wheel. Meet Zack Fleishman, the successful entrepreneur who is COO of Shark Wheel, the latest innovation in wheel technology that has changed the way we will roll forever.

Reinvented Wheel Is A Square

Could square wheels give you a better ride? One new project on Kickstarter is looking to fund the manufacture of sets of weirdly shaped wheels for skateboards. The design is based on a square, but tilted in a third dimension so that the squares actually roll in a smooth line. The project is popular: Five days after its launch, it's already exceeded its $10,000 goal.


Business partners David Patrick and Zack Fleishman are the minds behind the company Shark Wheel, a new take on skateboard wheels, using shapes found in nature. Patrick, a longtime skateboarder, says he stumbled on the design while working on a different project. He says the unique shape moves the way a fish swims or a snake slithers. Put the new wheels on a skateboard and he says it provides speed and better grip. "When you encounter a rock or a small object, we kick it left or right or we go straight over it, and that's a real big deal in the industry," Patrick said. In just a year on the market, Shark Wheel has gained support from crowdfunding, investors and major stores carrying their product.

Shark Wheel Reinvents The Wheel, Raises $30K And Counting For Square Skateboard Wheel

Amid the hullabaloo around Apple’s WWDC and the annual Electronic Entertainment Expo this week, it can be easy to overlook some of our oldest, yet most essential, technologies. Take the wheel for example. Sure, it works great, but it’s used the same boring round design for thousands of years. Isn’t it about time an update? The wheels of the future won’t have just one shape; they'll have three, according to Shark Wheel, a California company that says it has literally reinvented the wheel. The Shark Wheel is a perfect circle, a perfect cube and a perfect sine wave.


AFTER 5,500 YEARS, ONE MAN CLAIMS TO HAVE IMPROVED ON OUR GREATEST INVENTION—BY TURNING IT INTO A SQUARE. Teaming up with former tennis pro turned businessman Zack Fleishman, he raised almost $80,000 on Kickstarter before walking away from entrepreneurial reality show Shark Tank in 2015 with another $225,000. The Shark Wheel had scored its first bite.

L.A. Skateboard Company Reinvents the Wheel. Literally.

Their appeal becomes clear when, with a quick turn to the left, Patrick finds himself facing a crack in the lot, with tufts of grass and pieces of loose gravel. While this uneven terrain would be enough to make any rider flinch, Patrick tackles the patch, clearing it effortlessly. Stopping the board and picking it up, Patrick announces, "See, that's the benefit of the Shark Wheel."

The wheel reinvented as a SQUARE: Skateboarder raises $30,000 in 10 days to produce cube-shaped wheels he claims are faster and provide better handling

Shark Wheels are made up of three, helical-shaped strips that, when rolling, form a sine wave pattern when they make contact with the ground. This pattern allows the wheel to roll faster than a traditional round wheel, the company claims, and provides better handling on rough, wet terrain.

‘SharkWheel’ Inventor David Patrick Claims To Have Literally Reinvented The Wheel (VIDEO)

They’re currently designed specifically for skateboards, but with the right backing it’s possible they could end up on any vehicle you could name.

Squarish Wheels over Round Wheels?!

All our life if there’s one stereotype that has been emblazoned into our minds, it’s that the wheel is round. Right from those caveman cartoons, all the way till our fastest race-vehicle, the wheel may have changed in material and size (also becoming hubless), it still always remains round. Well, forget all that now, because according to designer David M. Patrick, the perfect wheel isn’t circular, but rather a scientifically calibrated blend of the circle, square, and the sine-wave.

The Company That Reinvented the Wheel

Although the wheel was purportedly invented back around 3500 B.C., its basic form hasn’t really evolved all that much. It’s still round, it still rolls, and most of us are just fine with that. Improve it? Not possible. As the old saying goes, “You don’t have to reinvent the wheel.” And then along came David Patrick.

Shark Wheel After ‘Shark Tank’: Interview With COO

Shark Wheel entered the Shark Tank in Season 6 debuting their unique version of a wheel. We talked to the COO Zack Fleishman about how the company is doing since the show. Here is what he told us about…

Shark Wheel Update- What Happened After Shark Tank

David has come up with a mathematically-balanced design that is based on a cube, and upon testing, they found that not only did the Shark Wheel roll, it rolled better. The wheel not only has a better grip on the ground but rolls faster and longer, and will roll over virtually any terrain.

Shark Wheel meets ‘Shark Tank’: Lake Forest company reinvents the wheel, gets on TV show

Instead of acting like a steamroller, plowing over a surface, the Shark Wheel’s alternating grooves channel debris out of the way and provide more grip than a traditional wheel

Where To Buy Shark Wheel From 'Shark Tank,' Because You Need To See These Square-Shaped Wheels In Action

You know how people say, "You don't have to reinvent the wheel," meaning that you shouldn't waste time trying to achieve something that has already been done for you? This is a very common saying because it's usually true, but did you ever stop to wonder what would happen if you did actually try to reinvent the wheel? Perhaps it could be even better than the one some caveman or cavewoman invented. That may be the case with the Shark Wheel, which appears on Shark Tank during Friday night's Season 6 finale


It looks like a square or cube rolling from the side, but from the rear view looks like a snake or three-dimensional sine wave in motion. The Shark Wheel is a revolutionary wheel design that offers superior performance advantages.

One BIG Update and Contact Info

over 2 years ago

Hi everyone,

First of all, please contact me at if you are on the waiting list. I can most easily communicate with you regarding next steps.

Big News:  Shark Wheel won the SBIR NSF Phase II grant. After applying for the $750,000 maximum in August 2018, Shark Wheel was approved for $724,000. This is huge news and the grant is specifically allocated for bringing the Shark Wheel farming wheel to commercialization. The wheel design will likely change a little bit from the below pictures, but this is what Shark Wheel built in 2018 with the Phase I grant funds.

Thank you everyone!

Shark Wheel Updates

over 2 years ago

Hi everyone,

  • Shark Wheel is in deep negotiations to close the pallet jack/forklift deal. The team flew out across the country to meet with upper management in person. Offers were presented on both sides and we are inching closer to a deal. We expect the deal to be signed no later than the end of June. This is a multi-million dollar multi-year deal
  • Shark Wheel received the order from Walmart. It is not close to $500k (what we anticipated). One of the big reasons for this was back stock from a previous Toys R Us order was used instead of ordering new boards. Our partner on this, Kazam (another Shark Tank company), had sold thousands of boards to Toys R Us previously. All of the Toys R Us stock is now going to Walmart is what we heard. The good news is we received the order and we continue to sell at Walmart. The next order should be what we were expecting.
  • Shark Wheel's next big market is casters. We keep getting requests from various companies to make small casters for varying applications. From utility carts that are sold directly to Amazon to sports equipment carts. 
  • Shark Wheel just received a $47,000+ royalty check last week for luggage. Shark Wheel is signing a new luggage deal. It is a 3 year deal that has minimum guarantees built into it. Shark Wheel gets to design its own luggage for the first time in the deal. Expect a Shark-branded luggage in the market this year.
  • Shark Wheel's government grant for the farming wheel is still in progress. The company has been awarded the $750,000 grant pending the final results of the audit. The audit was signed off completely about 3 weeks ago. Possibly due to the government shutdown, things have been delayed. We are told it is still a matter of weeks before we hear the final word. 
  • Shark Wheel signed up for the Outdoor Retailer trade show in Denver over the summer. We will be preparing many different items to exhibit at the show.
  • Shark Wheel has submitted a couple other government grants this year and is waiting to hear the results.
  • Shark Wheel continues to file more patents to strengthen its patent portfolio. The European Union patent (31 countries) will be issued in a few weeks (claims were just accepted). This is big news for us.
  • Shark Wheel's electric skateboard should be ready to sell in 2019. We are in late stage development.
  • Shark Wheel received 2 big orders this week:  the official Big 5 Sporting Goods order of 1,000 skateboards (a test order). Another order of 1,800 skateboards from a Danish distributor.
  • Shark Wheel will test its new wheelchair wheel design next week. If it performs well, we will consider entering the market in 2019.
  • Shark Wheel will be acquiring David Patrick's (Shark Wheel inventor) company for Frisbees. The Frisbee was originally licensed to Wham-O. Shark Wheel is finishing paperwork to officially own the company and begin selling it in 2019.
  • Shark Wheel will be taxed as a c-corp for 2018 - no one will be receiving a K1 for 2018 or ever again. Things are much easier now.
