This is the bizarre moment a petrol head competed in a motorcycle road race - in a jet-powered SHOPPING TROLLEY. Madcap Matt McKeown, 55, of Plymouth, Devon, build his wacky racer - which has a top speed of 80mph - from an abandoned cart he found in a ditch. He bolted on brakes, go-kart wheels and a 150 horsepower engine from a Chinook helicopter before taking it for time trials. Matt first set a record of 45.5mph then made several tweaks and broke his own record by reaching 71.4mph at Elvington Airfield in North Yorks. On Sunday (4/9) Matt wowed the crowds when he competed in the Shelsley Walsh Hill climb in Worcestershire. Despite crawling up the 1,000 yard course - which hits a steep 1:7 incline at its peak - Matt wasn't last to finish and managed to beat a number of other conventional bikes.
