About these units
Cycling Speed (cycle)
Typical cycling speeds vary dramatically by context: Casual cycling (4–7 m/s or 15–25 km/h), Road cyclists (8–12 m/s or 30–45 km/h), Professional racing (12–15 m/s or 45–54 km/h), Sprint track cyclists (peaks of 20 m/s or 72 km/h or more). Cycling is highly efficient due to mechanical advantage and reduced ground friction. Aerodynamics becomes a dominant factor at higher speeds, shaping bicycle frame design, wheel geometry, and rider posture. Cycling speeds inform urban infrastructure (bike lanes, safety regulations), sports training, and commuter planning. As a hybrid of human physiology and mechanical engineering, cycling speed provides insight into how technology amplifies natural human motion.
Kilometer/Second (km/s)
A kilometer per second represents a very high speed—1,000 meters every second—and is particularly important in astronomy, planetary science, and astrophysics. Orbital velocities around planets, escape velocities, solar winds, and the motion of stars relative to each other are commonly measured in km/s. This scale captures speeds far beyond terrestrial transportation. For example, Earth orbits the Sun at roughly 30 km/s, and meteoroids entering Earth's atmosphere may arrive at speeds between 11 and 72 km/s. km/s is a natural step up from m/s when describing the motion of celestial bodies.
