Often times the Darcassians needed to transport for short trips groups of 1 or 2 of their number. Training exercises were conducted once a cycle for newly recruited enlistees on the fine points of how to ride as the passenger and another for those learning to drive and operate them.

It was proclaimed these bikes will never fall from the sky no matter what ails them if the driver was skilled enough.
