Canadian Army Pvt. R.O. Potter of The Highland Light Infantry of Canada repairs a flat tire on his bicycle shortly after the Allied D-Day landings in Normandy. France. 20 June 1944.
Both the British and Canadian Army had issued their soldiers bicycles for the initial landings (Operation Neptune) on 6 June 1944 to help the soldiers get off of the beaches quickly and allow for more mobility during the ensuing Battle of Normandy (Operation Overlord).

Although we here in the States often see D-Day as an Omaha Beach main event and Utah Beach sideshow, the fact is that of 160,000 Allied troops to hit Normandy on 6 June, half were British and Canadians. This included around 24,970 men of the British 50th Division (Northumbrian) and elements of the 8th Armored Brigade on Gold Beach, 21,400 Canucks of the 3rd Canadian Division on Juno Beach, 28,845 men of the British 3rd Infantry Division and 1st Special Service (Commando) Brigade on Sword Beach, along with 7,900 airborne troops of the British 6th Airborne Div with attached 1st Canadian Parachute Battalion.
By July 4, a cool million Allied troops were ashore and looking to break out, many on two wheels.
