General Grievous
General Grievous rides a wheel bike in "Revenge of the Sith" during his confrontation with Obi-Wan Kenobi (Ewan McGregor). Grievous' vehicle is similar to another wheel bike that appears in the "" cartoon. One concept for Grievous' vehicle was for it to include "tank-like chariots"; at another point, the vehicle was going to be another droid.
