German Bicycle Troops

The rifles are Gewehr M91. Basically a Kar 88 with a stacking hook used by the Artillery, but these guys are not artillery troops.
The picture was taken circa 1892-1899.

Soldiers with Gew88, NCO(with gorget) with Kar98AZ, so photo probably post 1907 at earliest. The men may be reservists, or even LandWehr, as they look somewhat aged, and they are wearing the M1871 style valise ammo pouch (one only)

Some of the bikes in these pictures are way too big for the riders.

A Rifleman of the Prussian Guard (Patronentasche M1909;) uniform appears to be GJB M1910; (collar and cuff Litzen; Gardestern on Tschako, black/.white Feldzeichen) of the Radfahrer Kompagnie.
If pack is the special one for bicycle troops it didn't come out until 1912; Radfahrergewehr not approved until Dec. 1913; therefore, dating is sometime in or after 1914. Note short bayonet, probably S84 or KS 98. Radfahrers initially issued S98s which were carried on bicycle.

The Oath and its consequence

I swear by almighty God this sacred oath:
I will render unconditional obedience
to the Fuehrer of the German Reich and people,
Adolf Hitler,
Supreme Commander of the Wehrmacht,
and, as a brave soldier,
I will be ready at any time
to stake my life for this oath.
