JAMES PATENT CONVERTIBLE FRAME
1924 James Tricycle Model 25 Convertible
with De Luxe Rear Axle
Tricycles were expensive for companies to manufacture. As a result, they were loathe to over-produce them and most were only made to advance order. One solution was to design a convertible, which allowed them to produce one model rather than separate ladies’ and gentlemen’s versions. James patented the crossbar device that could be moved around to raise or lower it accordingly. This machine is fitted with the ‘De Luxe Back Axle’ as supplied to the ‘Gentleman’s Model No 25.’ The De Luxe axle, with external contracting band brakes at the inner ends of the half-axles, was introduced in 1914.
