The small ball is a great tool for beginners or kids who are just starting out with The Skill Board. The smaller size makes it easier to ride for smaller users and the distance to the ground is shorter, so it's easier to step off when you lose your center. It's specially reinforced to help it withstand the weight of the board and rider. 

Similar to a size 3 soccer ball, it measures about 7.5 inches (19 cm) in diameter. The pressure in the ball determines how difficult the ride is. Please see our Getting Started video for more information. Our recommended pressure is between 2-5 PSI. Going higher than 5 PSI may cause the internal reinforcement to fail. 

If you're buying a ball, then you will probably also need a pump.

The small ball is rated for 300 lbs (136 kg)
