A Hoverbike was a levitated motorcycle in the mid-21st Century.
Hoverbikes were used by both police and civilians, alongside more conventional, wheeled motorcycles. Many design elements were lifted from their predecessors, including features such as a front fork and a side car. They could levitate at low and intermediate altitudes, both on and off the Mag-way.
The term "Hoverbike" was never used in-show, but appears on storyboards of "Rebirth".
