Speeder bike
Speeder bikes and swoop bikes are small, fast transports that use repulsorlift engines in the fictional Star Wars universe. Return of the Jedi includes a prominent speeder bike chase; speeders and swoops also appear in Star Wars Episode I: The Phantom Menace, Star Wars Episode II: Attack of the Clones, Star Wars Episode III: Revenge of the Sith, Star Wars, and the Star Wars expanded universe's books, comics, and games.
Origin and design
Various concept sketches came from producer George Lucas' call for a "rocket-powered scooter" in Return of the Jedi. While Industrial Light & Magic's (ILM) Nilo Rodis-Jamero designed a blocky vehicle with a large engine, Ralph McQuarrie's designs were more fanciful but with less of a sense of the vehicle's power source. The final designs resulted in full-scale Imperial speeder bikes used by the actors for film against a bluescreen, along with miniatures mounted by articulated puppets. ILM used a steadicam recording at 1 frame per second to record the speeder bikes' path through the forest moon of Endor—in reality, a California forest. Playing the footage at the standard rate of 24 frames per second caused a blurring effect, which ILM used to simulate the vehicles' high speed; what was shot at 5 miles per hour (8.0 km/h) looked like 100 miles per hour (160 km/h).
