The Bikes: Mythical Beasts

Some bikes only made it into prototype stage. Others are rumoured to have made it to prototype stage but the evidence is not compelling. A number of spoofs/hoaxes were perpetrated. I will attempt to cover the various models that never made it onto the market, if not the road.
 

1914 770cc V-Twin

1914 V-Twin P&M were poised ready to a launch a V-twin in 1914 at the outbreak of WW1. The demand for the RFC model meant that the twin never made it into production. This 6 h.p. 770cc (76 x 85mm) machine had a four speed gearbox and, despite these radical changes, used essentially the same frame as the 3.5 h.p. model. (Picture provided by Volker.)

1915 770cc V-Twin

The V-Twin was further developed and made it as far as the catalogue for 1915. These pictures show left and right views of the 1915 prototype.

This picture shows detail of the engine.


I am grateful to Mats Berglind for these pictures scanned out of the 1915 P&M sales catalogue.

1916 770cc V-Twin

The fourth prototype V-twin (HM 7) was built in 1916 and road tested by "The Motor Cycle" and was probably used by Richard Moore as personal transport.

1928 500cc V-Four

A V4 version of the Panthette was conceived of as a spoof for 1928, but never built.

1940 500cc In-Line Twin

Name - twin40cb.JPG, Source - Classic Bike, Size - 27kThe Panthette was the only twin Panther to make it into production and on to the market. 

Granville Bradshaw (who also designed the ill-fated Panthette) built for 1940 this 500cc in-line twin. It has essentially the same frame as the Model 90. Apparently the sole machine built by P&M was used by P&M for over ten years. It subsequently disappeared and may still be in existence. 

Perhaps not entirely clear from this picture is the fact that the rear suspension is of a leaf-spring design. This parallelogram shaped system was a simple bolt-on upgrade to existing frame designs. It appeared in 1939 but had problems in terms of safety and costs. 

I am grateful to  for permission to reproduce this picture from the March 1996 magazine.
