December's document of the month is a schematic drawing of an BSA Army issue Mark IV Bicycle. While there have been many variations to this bicycle this is the only drawing currently in Military Archives holdings.

These bicycles were issued to the soldiers of the cyclist corps under direction of the Director of Cavalry. In the case of the LDF once their initial training was completed a bicycle was issued to them to facilitate their attendance at their training camps.  

As well as the schematic drawing uploaded, December's document of the month includes a manual on Army Pedal Bicycles. This manual is part of the Military Archives collection of Training Manuals and Regulations.
