And ...
There are no rules to determine how a unimotorcycle should look.

The unimotorcycle should be build in such a way as to let the pilot race the 30,48m as fast as possible. During a run, the unimotorcycle must not touch the ground before the wheel axle, so finding the correct balance is important.

A secondary consideration in the design of the unimotorcycle is what happens after the 30,48m. Keep in mind that the pilot might want to put down and stop the unimotorcycle gracefully (as in without crashing).
