Shark Wheel

Rather than a traditional circular shape, the Shark Wheel is a hybrid of a sphere and cube taking on the properties of both shapes while in motion. It has been touted as the reinvention of the wheel by various news outlets. The wheels were initially funded by a Kickstarter campaign that reached nearly eight times its initial goal. It attracted the attention of award-winning skateboarders and has won various competitions around the world. Shark Wheel also appeared on ABC's Shark Tank in May 2015 as the season finale.

The shape of Shark Wheels came to David Patrick while he was working on an unrelated scientific pursuit. The shape of the Shark Wheel was known to be a perfect cube, but when the Shark Wheel shape was accidentally dropped, it rolled. Perfectly. The wheels appear to be square, but roll smoothly like conventional wheels. Its single or multiple interlocking rings are based on sine wave patterns, which create a thinner contact patch with the pavement compared to a conventional wheel of the same width.
