A bike handlebar is a crucial component of a bicycle that allows the rider to steer and control the direction of the bike. Typically made from materials like aluminum or carbon fiber, handlebars come in various shapes and sizes to suit different riding styles. They are attached to the bike's front fork and provide a grip for the rider's hands. Handlebars can also accommodate accessories such as bike bells, lights, and computer mounts. Different types of handlebars, like drop bars for road bikes and flat bars for mountain bikes, cater to specific cycling needs, enhancing comfort and performance during rides.
