Kyle, 12, who competes in the British Youth Championship, scored 14 points in the qualifying races in Germany, one behind the Czech Adam Fencl and Dutch rider Jarno De Vries.
And then he defeated both along with Poland’s Marcin Turowski in the A Final at Bad Hersfeld.
Fellow British rider Zach Wajtknecht was classified 10th after scoring eight points in the qualifiers.
Kyle, of Sarsfield Road, Workington, romped to victory in front of 2,000 spectators at the East of England Showground in Peterborough last month to become the first junior rider to successfully defend the British 125cc Championship title.
The Stainburn School pupil was riding against the top 12 Under-16 youngsters in the country who compete on 125cc bikes. He won all four of his qualifying heats to go into the final as the competition’s top-scorer.
In the final he made a flying start out of tapes and led all the way to the flag. He also recorded the fastest time of the day in his first heat when he cruised to victory in 71 seconds.
Kyle has been praised by GB Youth co-boss Neil Vatcher, who said: “Everyone watching at Peterborough was impressed with the high quality of racing and the fast race times. If these 12 British hopefuls can continue their progress, British Speedway has a very bright future.”
Bickley’s victory will see him rub shoulders with reigning speedway World Champion Tai Woffinden at an awards ceremony in January for this year’s British champion riders.
Last month Woffinden narrowly beat Cleator Moor’s Craig Cook to win the British Final at Wolverhampton.
