London: Hong Kong's talented young track cyclist Wai Sze Lee has only been competing in sprinting a year but at the 2012 Olympic Games test event she produced enough speed to beat the world's finest competitors.

A scintillating burst to clinch a silver medal in the keirin event on Sunday gave fans a taster of things to come from the 24-year-old, who also won bronze in the individual sprint by beating Olympic champion Victoria Pendleton of Britain.

Having flown past keirin world champion Anna Meares of Australia, Lee said she was amazed at her medal-winning antics, which she described as her best yet, and hopes she can put in a repeat performance come the Olympics in August.

"There are many strong riders here, so to get a medal...unbelievable. I have a chance at the Olympics, a little more practice," Lee, puffing heavily, said at the venue that will host 10 Olympic medal events between August 2-7.

"I hope I can win against all the women and be world champion too," she added in reference to the world championships in Melbourne from April 4-8.

Home favourite Meares, who survived a career-threatening crash in 2008 when she was millimetres from needing a respirator to breathe for the rest of her life, will provide stern opposition for Lee at the worlds.

The 28-year-old former Olympic champion had some words of advice for Lee however. Stick around.

"This is a sport that is very responsive to age and time. It's not a sport where you have strength, speed, power, experience and the ability to be able to fly down the track," said Meares.

"It takes time, and if you stick around the sport long enough you're going to be able to see those improvements consistently roll throughout your career.

"I think she's one to be watched," she said of Lee, who trains in China and in 2011 won medals at the World Cup in the non-Olympic 500-metre time trial and also finished fifth in the same event at the world championships.

At the Beijing Olympics, only Guo Shuang of China in the women's individual sprint and Japan's Kiyofumi Nagai in the men's keirin managed bronze medals for Asian countries, so Lee faces a battle to put Hong Kong on the cycling map.

All she cares about for now, however, is getting tips off her "idol", Britain's four-time Olympic champion Chris Hoy.

"He's very gentleman," Lee said in halting English after three hard days of competition, during which Hoy was back to his blistering best by winning two events.

"He's my idol. I hope I can speak with him. I love Chris Hoy very much. No matter how far behind he gets he always catches the riders."

Hoy saw a lot of potential in Lee's World Cup performances. "I think she did an 11-second lap in the sprint, that's pretty impressive," said Hoy, who clocked 71.8-kilometres an hour during his keirin triumph on the lightning-quick track.

"That's very nice if she's a fan. I'd love to speak to her, though I don't want to give her too much advice if she's racing against Vicky (Pendleton). Maybe after the Olympics," the Scot grinned amid a media scrum.
