[1] They became identified with a design of motorcycle which had a large sloping 40-degree single-cylinder engine as a stressed member of the frame.
The Phelon & Rayner 1.75 hp machines were only in production until 1903, but they also licensed the design to Humber Limited, who produced motorcycles based on it from 1902 until 1906.
[4] After Harry Rayner died in a car accident, Joah Phelon went into partnership with Richard Moore.
[9] In July 1914 P&M revealed details of their prototype 90 degree V-twin, their first deviation from the single cylinder motor cycles for which they were known.
The combination of the advent of cheap cars and the collapse of the British motorcycle industry brought production to an end.
The early postwar models (both Lightweight and Heavyweight) were fitted with air/oil damped Dowty "Oleomatic" telescopic forks.
This gave P & M the chance to develop their own scooter, the Panther Princess, but it was not a success and helped bring about the demise of P & M as motorcycle manufacturers.
