At first I thought this thread was posted in the wrong forum...
Utility, as it relates to bicycles, could be defined as- the quality of being of practical use. I can't find anything practical about those monsters.

But I gave it a little more thought... Those bikes do satisfy the economic definition of utility- the capacity of a commodity to satisfy some human want. I know this becasue after seeing them, I want one.

Neat machines, thanks for sharing.
