A rola bola, also known as a balance board, consists of a flat plank balanced on an unattached cylinder. The cylinder rolls when weight is placed on the plank, causing the rider to need to adjust their weight to remain balanced.
The following general criteria apply to all RecordSetter record attempts involving a rola bola:
- rola bola cylinder must be six inches (15.24 cm) or greater in diameter
- attempt must be performed on a hard, smooth surface (no carpet, grass, etc.)
- must remain balanced on the rola bola for the duration of attempt; attempt ends if balance is lost
