A Tricycle is a human powered three-wheeled vehicle used for traveling over land.
In 1968, Cate Archer and Magnus Armstrong were chasing the assassin Pierre the Mime King at the last scene of their mission 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. As Pierre rode off, Armstrong found a tricycle nearby and told Archer "You shoot, I'll drive."
- While on the tricycle, Archer will not run out of ammunition for her M1921-A1 Submachinegun but still have to reload it.
