While doubtless many an Auxilier made his way on his own bicycle to and from training, these were private civilian bikes. The Scout Sections had bicycles listed on their War Establishment of equipment to be issued. The earliest listing from 7 Nov 1941 includes 10 “bicycles, folding” in military parlance. These were not the lightweight "parabike" seen later in the war, but a standard heavy duty bicycle with hinges added, allowing it to fold in half. They were fitted with a carrying harness, being intended to be carried across rough country. However, in Auxiliary Units service, their folding nature meant they could also be lowered into an OB after invasion for safe keeping.
The bicycles do not seem to have been widely used. In Suffolk, the Scout Section were photographed on a training ride in the snow, designed to build up their stamina. Of note, the bicycles in the photo appear to be the standard British Army Mark V model, suggesting that the folding model proved hard to come by. A later War Establishment refers to 10 bicycles, with no type specified at all. By then each section also had a light (15 cwt) lorry for transporting the men.
The other location issued military bicycles was Coleshill House, whose equipment issue included 21 bicycles, presumably to allow the staff to get around the large estate. However, they also seem to have been used to get into Highworth for social events as well.
