A short-lived model, introduced for the 1924 season by combining the 4½ h.p. model's 596cc engine with the cycle parts of the 3½ h.p. Standard model.

The Model 4 profile in the 1924 catalogue mentions: “ It will appeal to those who require an outfit of considerable horse power and yet do not wish to include the refinements incorporated in our 4 ¼ h.p. Model 7.”
