In this world, the internal combustion engine and all forms of motorized propulsion simply never existed. The concept of a car, a plane, or even a simple motorboat is alien to human history. Human civilization has evolved entirely around the wheel, the chain, and human muscle power. The streets of Miami are not filled with the roar of engines and exhaust fumes, but with the rhythmic clicking of gears, the whirring of chains, and the constant breeze created by thousands of spinning pedals. The infrastructure roads, paths, and city layouts is designed exclusively for cyclists, with wide lanes and endless bicycle parking. Because everyone travels by bike, physical exertion is a constant part of daily life. Consequently, hygiene facilities are integrated into every aspect of society: showers are mandatory in workplaces, standard in restaurants, and public shower buildings are scattered throughout every park to accommodate the sweaty travelers of this pedal powered world
