The Sideways bike is made of “three semi-circular canals positioned at right angles to each other that detect balance in three axes. These canals are separate and distinct. The three types of balance are Left to Right, Front to Back and Rotational (Yaw). Left to Right balance is what people are most familiar with and is the primary balance used for riding a regular bicycle or indeed flying a plane.” Really cool project by a guy from Dublin, and after living there for as long as I did, I still never saw him riding around! (Darn!) Oh well next time!
