[1] Lowther, born in Low Fell, Gateshead, began racing speedway bikes on the grasstrack circuits in Newcastle.
In 1936, after a trial with Southampton Saints he was offered a deal but chose to join Bristol Bulldogs,[2] where he rode in the 1936 Provincial Speedway League season.
However, the following season in 1937, Lowther started racing at Leicester and then Middlesbrough and Rye House respectively[4] before competing in the league for Harringay Tigers.
Lowther struggled at Harringay in the reserve berth, which led to him completing the 1983 season on loan with the Lea Bridge Cubs in division 2.
[7] He then found a home at Glasgow, known as the Lions at the time but the season ended early due to World War II.
