Well, just achieving any build goal, such as propulsion, braking, power transmision in an unorthodox and complicated manner. A rat-bike with a Happy Time would not be a good candidate. A jet powered MTB with front coaster brake operated by a Susan Summer's thigh master would.
Fish gut's build is a great example. A steam powered, converted HT engine. Which is an uber cool thought.
"a contest to build a ridiculously complicated (but safe) MotorBicycle. Where points are awarded for achieving a goal such as braking, gear reduction or propulsion etc, in the most round about and complicated way."
