JD were motorcycles produced from 1922 to 1926 and marketed by the Bowden Wire.

  • 1922 The first machine appeared as a miniature that had a 116cc two-stroke engine clipped to the inside of the front downtube of a safety-cycle frame. It had magneto ignition and drive by chain to a friction pulley working on the inside flange of the rear wheel rim. Clipped beneath the frame top-tube was a slim fuel-tank. It had braced, unsprung forks and appeared to be no more than a motorized bicycle.
  • 1923 A further model was added. This had an open ladies'-style frame.
  • 1924-1925 Those models continued with little change.
  • 1926 Only the gents' model was listed, after which, there was nothing more.
