Kovika had the Frost Cycle built shortly after his coming to BZ-Nui.
The Toa of Ice uses it regularly to get around BZ-Metru.
The Frost Cycle is powered by Kovika's Ice powers, and is constantly at a very low temperature. Shadow makes a point of staying far away from it due to the cold.
The bike is equipped with dual Ice-blasters on either side of the hull, and the windscreen features a head-up display.
