Bicycle handlebar or bicycle handlebars refers to the steering mechanism for bicycles; the equivalent of a steering wheel. Besides steering, handlebars also often support a portion of the rider's weight, depending on their riding position, and provide a convenient mounting place for brake levers, shift levers, cyclocomputers, bells, etc. Handlebars are attached to a bike's stem which in turn attaches to the fork.
