Cyclist
In short
A person who rides a bicycle or other pedal-driven vehicles for transport, sport, or leisure.
In plain words
A cyclist uses human power to move a vehicle with two or more wheels. They might do this to get to work, to stay fit, or to race in competitions.
A simple example
A commuter riding a mountain bike to the office is a cyclist. A professional athlete competing in the Tour de France is also a cyclist.
Why it matters
Cycling provides a low-carbon way to travel and improves physical health. It is also a major global sport with massive professional audiences.
Easy to mix up
Do not confuse a cyclist with a motorcyclist, who uses an engine rather than pedals for power.
