How far could a biplane fly before refueling?

The range of a biplane before needing to refuel can vary significantly based on the model and its fuel capacity. Generally, early biplanes had a range of about 200 to 500 miles. Modern biplanes, particularly those designed for aerobatics or agricultural use, may have similar or slightly improved ranges. Factors such as load, weather conditions, and flying speed also influence the actual distance flown before refueling.
