A Brief History of the Marque
Built during the pioneer era of British motorcycling, between 1903 and 1906 Smith & Molesworth of Coventry produced a range of machines powered by a variety of Sarolea engines.
The Alert motorcycle was a very primitive machine with the engine hung from the downtube. There were two models in the range - a 2.25hp Alert with a Belgian Sarolea engine and the 2.75hp or 3.25hp Coventry Alert. There was also a model with a Montgomery sidecar. The company also supplied fittings to the trade.
The same company was producing motorcycles, sidecars and bicycles in 1920.
