1913 - 1915
The first J.B.S. was a cyclecar powered by an 8hp V-twin J.A.P. engine, though more civilised than many in that it had shaft drive. For 1915 an 8hp V-twin Blumfield and a 10hp 4-cylinder Dorman engine were offered. So far as is known the J.B.S. was not revived after World War I, though a note in Fletcher's Motor Car Index stated 'Manufacture may be resumed in the near future'.
