In April 1935, David Bowman commenced operating a weekly bus service from Hope Valley to the Adelaide city centre via Peserverance Road.
[1] A second service from Tea Tree Gully to Adelaide via North East Road later commenced.
[1] By the early 1970s, Bowman's had expanded to operate nine routes: With falling revenues and rising costs, on 11 February 1974 the routes of Bowman's, along with those of 11 other operators, were taken over by the Municipal Tramways Trust.
When operations ceased in February 1974, the fleet consisted of 36 buses and six coaches.
[1] In 1970, Bowman's opened a state of the art facility in St Agnes.
