A bicyclist is someone who rides a bicycle. You might see bicyclists pedaling along bike paths in parks, commuting to work on city streets, or racing in competitions like the Tour de France.

The word describes anyone on a bike, whether they're a professional athlete training for hours each day or a kid riding to a friend's house. A bicyclist in Amsterdam might use their bike as their main form of transportation, weaving through traffic alongside thousands of other cyclists. A mountain bicyclist tackles rough trails and steep hills, while a casual bicyclist might ride around the neighborhood on weekends.

Bicyclists need to follow traffic rules just like car drivers, stopping at red lights, signaling turns, and watching for pedestrians. Many cities are building special lanes just for bicyclists to make riding safer and easier. The word is interchangeable with cyclist, though bicyclist specifically emphasizes the two-wheeled bicycle rather than other types of cycles, like tricycles or unicycles.
