A handlebar is the part at the front of a bicycle that you grip with your hands.
When we think about handlebars, we often picture a bike ride through the park or along the beach. Handlebars are like the steering wheel of a car, but instead of turning the wheels, they help guide the bike in the direction you want to go. You lean forward slightly when gripping the handlebars and shift your weight from one side to another as you turn the corners. If you're on a mountain bike with wide handlebars, it's like being on an adventure - you can lean into the turns and feel really connected to the ride.
(chiefly in the plural) The bar used to steer a bicycle, motorbike, or similar vehicle using the hands.
