Due to Stem City's cramped and rough road infrastructure, there isn't much comfortable transportation for the average citizen besides walking. Larger off-world aliens are paid by noble companies to wheel around open wagons that function as taxis and cramped buses. The occasional rickety electric scooter can be found, though they're mostly owned by the richer noble class or in the possession of gangs.
Outside of the city walls, some more options are available. Transport buggies are decently commonplace for those with the funds available to buy the parts to assemble them. Jest Clorentine's tram runs from a station near Stem City's Fungal Plains lifts straight to Gillsway.
