1900 This was one of a number of firms that bought in Belgian Minerva engines to attach to its bicycles.
1902 After the move to Caledonian Road, a forecar attachment was offered. This replaced the single front wheel by two that carried a seat between them. Removal was said to take only a few minutes. The attachment was sold as the Trimo and could be fitted to most other makes. It was therefore very popular.
1903 A Trimo was adapted to use a Singer motor-wheel in place of both its engine and the usual rear wheel. They also built a model fitted with a new 3hp Minerva engine that had a cam-operated inlet valve. The motorcycle remained the same with the engine hung from the frame.
1904 The model remained unchanged but with variations of transmission available. Later in the year a ladies' version of the Trimo was added, with a drop frame and upright engine.
1905 The range of solos continued, with the option of either belt or chain drive, either with one or two speeds, plus the forecars. A solo ladies' model was also added, this with a 2hp engine fitted to an open frame.
1906 The open frame became available for general use, fitted with a 2hp or 2.75hp engine and two-speed gearing. The Trimo became more car-like in appearance.
1908 The solo, known as the Cob, had a 3.5hp Fafnir engine. Although all the Phoenix machines were well-made and widely advertised, production had always been small-scale so they were not competitive enough to remain in the trade.
1911 Around this date they moved the business to Letchworth
