Zack Leader is a boy racer with a difference - instead of relying on horsepower, the 14-year-old gets his energy from gravity.
Zack, from Wragby, took up the extreme sport of gravity bike racing last year and competed in the Belchford Downhill Race after seeing an advert for the event.
He finished a respectable ninth out of 12 racers despite having just six weeks to prepare for the race.
Zack said: “I’ve wanted to race motorbikes since I was about 9 and I knew there was a local event for gravity racing at Belchford.
“I looked on the website and the had no space left for the soapbox and sidecar but they had some space left for gravity bikers.”
Zack then converted his younger brother’s BMX bike into one suitable for racing by taking off its pedals, chains and lowering the handlebars - modified bikes can reach speeds of up to 50mph.
“My brother wasn’t too pleased that we’d modified his bike, but he warmed to the idea eventually,” Zack said.
He then took seventh place at the Worlaby Downhill Challenge in July and has set up his own team - Blue Dream Onit Racing - with friend Ryan Talbot, from Scamblesby.
Plans for next year are already in full swing, but were sidetracked after Ryan broke his collarbone in a test run.
Zack added: “We know about the dangers of the sport, but it’s the same as push bikes - you can always fall off them.
“It’s not put me off at all.”
Blue Dream Onit Racing are planning on entering races at Lincoln Arboretum and Worlaby in 2014.
Zack cites British Superbike Champion Alex Lowes as one of his inspirations and has a keen interest in racing motorbikes when he gets older.
“I need to thank my mum for all her help as well,” Zack continued.
“I’d also like to thank James Ellison, Print-Design.co.uk, lack & White Bikes, Spilsby, Clippers Hair Salon, Louth, Josh Waters, Ben Wilson and Dan Verity.”
