Monowheel
The Monowheel is a custom-built, one-wheeled vehicle originally designed on Ruthia for law enforcement patrol and pursuit. Today it is best known as the vehicle of choice in mono racing.
In most races, the shell of a monowheel follows a tight set of rules; however, the internals, materials, and electronics are all custom to each driver and race.
The standardization of the shell has given rise to iconic displays of graphics and style on the body of each monowheel, often being associated with a specific driver or team of drivers.
Rollers
Heavily modded all-terrain variants known as 'Rollers' are armored and weaponized, used in less governed areas for survival races.
