Jack Hargreaves (16 December 1912 – 15 January 1944) was a motorcycle speedway rider from England.[1]
Hargreaves, born in Keighley, West Yorkshire, began racing for the Liverpool team that raced at Seaforth Greyhound Stadium, although Seaforth did not race in the National League.[2] He began his British leagues career riding for Liverpool Merseysiders during the 1936 Provincial Speedway League season, where he reached the final of the National Trophy.[3]
In 1937, the Liverpool team withdrew mid-season and Hargreaves (who had topped their averages) joined the Belle Vue Aces in the top league,[4] contributing towards the team as they won both the National Trophy and A.C.U. Cup double.[5]
He was again part of the Belle Vue team, when they won the 1939 National Trophy, just before the season was ended by World War II. He averaged 6.18 that season.[6] He also reached the Championship round of the 1939 Individual Speedway World Championship.[7]
During the war, Hargreaves was a car mechanic in a local garage, but he died as a result of a road accident on 15 January 1944, when the motorcycle he was riding collided with a bus. He died shortly afterwards in hospital. [8]
