1920 - 1924

The L.S.D. 3-wheeler was a Yorkshire product through and through, being designed by a Mr Longbottom and made by Messrs Sykes and Sugden.  Only the engines came from further afield, being V-twins by MAG or J.A.P. of 964cc driving through a 2-speed gearbox and chain to the single rear wheel.  Unlike many 3-wheelers, the L.S.D. was fitted with a reverse gear.  Suspension was unusual, being independent by horizontal coils at the front, and quarter elliptic at the rear.
