25th (County of London) Cyclist Battalion

25th (County of London) Cyclist Battalion was a bicycle battalion of the London Regiment of the British Army. The battalion was converted to a unit of the Royal Corps of Signals in 1922. The unit was originally formed on 26 February 1888 as the 26th Middlesex (Cyclist) Volunteer Corps, as part of a growing interest in the use of bicycles for military uses. It originally comprised three troops lettered 'A' to 'C' and was originally linked to the King's Royal Rifle Corps. It was attached to the Inns of Court Regiment and was affiliated with the Rifle Brigade (The Prince Consort's Own).

In 1908 on the formation of the Territorial Force as part of the Haldane Reforms the unit became part of the newly created London Regiment.

Men from the unit took part in the campaign in Waziristan (1919), 3rd Afghan War and some were present at the Amritsar Massacre in 1919.
