A Unicycle is a human powered single-wheeled vehicle used for traveling over land.
In 1968 Cate Archer and Magnus Armstrong were chasing the assassin Pierre the Mime King in the streets of Calcutta India. As Armstrong grabbed for Pierre, the slippery Mime slipped out of his coat revealing that he was actually a short man riding a unicycle.
Using the unicycle, Pierre was able to escape from Archer and Armstrong who were chasing him on a Tricycle.
- Once Pierre's disguise had been penetrated, he discarded the unicycle.
