Bicycles (Cykel) in Generation Zero were added in the June Update 2019.
The bicycle is the slowest vehicle in Generation Zero going 30 km/h on a road and even less on uneven terrain such as grass.
Bicycles can be spawned at vehicle stations found at various safehouses. There are 3 different bicycle variants, the Cykel - Sky Blue that you start with, as well as Ruby Red and Emerald Green.
When using a bicycle, you cannot shoot and you will be slowed down when riding along rough terrain that's not road.
Similarly to locations, the bicycle can be tracked (marked as such) on the map, thus making it easier for players to orientate to the place where the bike is.
In-game description of all bicycles: "The Cykel is a jack-of-all-trades bicycle of Swedish made. Sturdy and able to gain a great deal of speed on flat terrain."
