The unique 30-degree approach angle of the Shark Wheel reduces shock and deflects objects due to its approach angle. Shark Wheels perform similar to how drivers intuitively know to go over a speed bump at an angle to reduce the shock in their car. The 3 lips of the Shark Wheel compared to 1 lip on a traditional wheel give predictable slides. A normal wheel is a steamroller and tries to go over obstacles in its way.
