Daniel Dhers of Venezuela claimed BMX freestyle park spoils at the International Festival of Extreme Sports (FISE) World Series leg in Jeddah.
British rider Declan Brooks had led after the qualification round but the technical prowess of Dhers was too strong at the Action Sports Complex venue in Old City.
Brooks ultimately took second place as Anthony Jeanjean of France took bronze in Saudi Arabia.
BMX freestyle part is due to make its Olympic debut at Tokyo 2020.
It came in a three day event in Saudi Arabia attended by a crowd of 137,000.
This was billed as a record for a FISE World Series event.
France's Joseph Garbaccio was among other winners in the skateboard park.
He scored 81.00 points to beat Spaniard Danny Leon, who scored 80.00.
Alex Midler of the United States took bronze with 77.00.
French success continued when Nabil Hadim won the street parkour competition.
He finished first ahead of Erik Mukhametshim of Ukraine and Li Yiqi of China - with a full breakdown of scores also yet to be published.
Parkour has been amalgamated into the International Gymnastics Federation and could be proposed for inclusion at the Paris 2024 Olympics.
Skateboard park is also debuting in Tokyo.
Hiroshima will host the next leg of the FISE World Series from April 6 to 8.
