Until the mid-sixties, Bournbrook was the home to Ariel motorcycles owned by first Charles Sangster then his son Jack Sangster, and with their main factory in Dale Road. Ariel was the first motorcycle company to employ noted designer Edward Turner from Peckham to join their established engineer, Val Page. He introduced the Ariel Square Four model and re-vamped their Ariel Red Hunter range. Ariel acquired Triumph motorcycles before the Second World War and, with Triumph, was itself later absorbed into the Birmingham Small Arms group when Jack Sangster joined their board. Although introducing new models, the Ariel Leader and Ariel Arrow, the Bournbrook site gradually lost importance within the BSA group with their final model, the ignominious Ariel 3 being wholly produced at Small Heath.
