Handlebars are the levers used to control steering a bicycle, scooter, or another two-wheeled vehicle. Depending on their purpose, they are also called 'steering controls,' 'handgrips,' or 'handlebars.' If you want to know more about handlebars, they are usually mounted vertically on the frame of a bike, scooter, or trike. They can be moved backward or forward to alter the bike's direction.
