[This post is adapted from one I put on a British Military forum some time ago ....]I understand that the first recorded use of military cyclists was in the Franco-Prussian War of 1870-71, although the cycles used were apparently of the early "velocipede' kind. As already noted, bicycle Troops really became the "in" thing, in the late 19th century, after the development of the chain-drive "safety bicycle" (the configuration with which we are familiar today) and practical pneumatic tires, by the mid-1880's.
Here are a few items I have collected .... (Click each thumbnail to enlarge.)
First, a photograph of the Cycle Corps of the U.S. 25th Infantry (a Black unit) at Fort Missoula (Montana) in 1897. That summer this unit completed a rather historic trip via bicycle from Fort Missoula to St. Louis ... a distance of some 1900 miles!
An unidentified British cyclist Rifleman, likely a volunteer since he appears to have a Martini rifle, and this photograph undoubtedly dates to the 1890's when Regular Army units were already armed with bolt-action Lee-Metford or Lee- Enfield (i.e. "Long Lee") rifles. (Can't identify the unit, since the original photograph was marked as having been taken in "Clifton", but there are several towns with that name in the UK ...)
A cyclist of the Cheshire Regiment - a Regular ..... note his lovely Lee-Enfield. His bandolier is the Pattern 1888 bandolier, adopted the year the .303 Lee-Metford rifle went into service, and basically just a downsized version of an earlier bandolier for the sizable .577/.450 Martini-Henry cartridges. Note that the cartridges were still held in individual tubes, however. The first British Lee bolt action rifles, although having 8-round and later 10-round magazines, were still loaded one round at a time. The "charger loading" system (i.e. stripper clips of a sort) was not introduced until adoption of the "Rifle, Short, Magazine, Lee-Enfield" - i.e. "S.M.L.E) in 1903 ...
Members of the Yorkshire Regiment and the Gordon Highlanders ...
Detail scanned from a print entitled "The Canadian Militia, 1898" - this being a cyclist of the 3rd Battalion, Victoria Rifles ...
Here is an interesting set of drawings published in
The Graphic of May 9, 1896 over the general caption
"The 'Wolseley' Cyclist-Infantry Challenge Cup Competition, from photographs by Major J. Fortun Nott" .... Notwithstanding that the U.S. Army was soon to give it a try, here is a rather tongue-in-cheek commentary on British military cyclists which appeared in the New York Times in September of 1894 ...
