Handlebars are a type of steering mechanism commonly found on bicycles, motorcycles, and some types of vehicles. They provide a way for the rider to control the direction of the vehicle by turning them left or right. Handlebars come in various shapes and sizes, designed for comfort and performance depending on the type of riding. In addition to their use in vehicles, handlebars can also refer to a style of facial hair, specifically a mustache that extends outward at the ends. This style is often associated with a vintage or classic look and can be styled in various ways, sometimes requiring grooming products to maintain its shape.
