1902 Acme began production at Osbourne Road in Coventry. Probably founded by Frederick W. Allard. The first motorcycles had Minerva engines followed by the 2.75hp Auto-motor. They then built a 3hp Acme model themselves. A 4.5hp Auto-motor was also listed for trailer use.

1904 Acme were making the Auto-motor engine themselves.

1908 Two Acme machines were entered in the Island TT, but both retired. They did not enter the TT again.

1918 They used JAP units and their own side-valve 348cc singles and 997cc V-twins.

Around this time George Henry Hemingway was managing director

1919 Manufactured a car for a limited period[1]

1920 A model was manufactured using a 976cc V-twin engine. The three-speed gearbox was chain driven.

1921 A 2.75hp single joined the twin. It had two speeds and a chain-and-belt drive. The two machines were very similar to those produced at the Rex Motor Manufacturing Co factory at nearby Earlsdon.
