Cycling, [1] also known as bicycling [2] or biking, [3] is the activity of riding a bicycle or other type of cycle. It encompasses the use of human-powered vehicles such as balance bikes, unicycles, tricycles, and quadricycles. Cycling is practised around the world for purposes including transport, recreation, exercise, and competitive sport.
To put that into on-the-bike terms, that means a cyclist with better cycling economy uses less energy to produce, say, 200 watts for 30 minutes than a cyclist with a lower cycling economy.
From a mechanical viewpoint, up to 99% of the mechanical energy delivered by the rider into the pedals is transmitted to the wheels (clean, lubricated new chain at 400 W), although the use of gearing mechanisms reduces this by 1–7% (clean, well-lubricated derailleurs and a straight chainline), 4–12% (chain with 3-speed hubs), or 10–20% (shaft drive with 3-speed hubs).
Sprinters have a higher ratio of fast-twitch muscle fibers than non-sprinters. Road cycling sprinters sometimes tend to have a larger build than the average road racing cyclist, [4] combining the strength of their legs with their upper body to produce a short burst of speed necessary in a closely contested finish.
