Also called rollers, zips or wheelers, wheevees are ground-based passenger conveyances. Wheevee is the industry standard name, but also a trademarked product line from Tealef Vehicular Magineering. Much like their airborne siblings, the most commonly produced wheevees are the one and two passenger models. The high occupancy vehicle equivalent are called - and trademarked - Wheehovs (pronounced Wee-hoves).
