From February 5th to March 20th, 2005, several Belgian military bicycle enthusiasts worked together to create a  20th century military bicycle exhibition in Nieuwpoort, Belgium. The expo was named 'Oorlog op 2 Wielen' (Flemish for ' War on 2 Wheels') and featured roughly 20 bicycles from 1905 to 1995. The oldest bike on display was a French Capitaine Gerard Folding Bicycle from the Great War and the youngest a contemporary 1995 Belgian Army bike....
Bicycles came from the collections of Philip Moreau, Cris Ryckewaert, Jean Lummerzheim, Gustaaf Desmet, Eric Baecke, Eric Delanghe and from my own collection....
