This short article describes aerodynamic research carried out using the Moulton small-wheeled bicycle. Alex Moulton's initial research, applying streamlined cowlings to his early small-wheeled bicycles, is briefly described. His later collaboration with Douglas Milliken is covered in greater detail. Milliken's many experiments with fairings included wind tunnel tests in crosswinds, an aspect of bicycle science rarely investigated hitherto. An important finding was the ability for a streamlined bicycle under certain conditions to sail. The Moulton—Milliken collaboration led to the development of fully streamlined bicycles, using the conventional riding position, which twice broke a speed record.
