The 18-year-old will be the youngest disabled athlete to represent Australia at the Para-Cycling Track World Championships in Los Angeles next month.

"It's exciting to be going to the world championships and I feel really honoured to be the youngest person on the team," Kennedy said.

"I don't think about my disability when I compete, I just go for it."

Kennedy had not cycled competitively when she joined Parramatta Cycling Club three years ago and since then has been improving steadily.

"It's really helped to train with and race against able-bodied athletes; it's really motivated me to push myself to beat them."

She will compete in the 500 metre time trial and the three kilometre pursuit races at the championships.

The former Tara Anglican School for Girls student said sprinting is her strength but she enjoys road cycling as well.

"I haven't always been into sport, my year 8 teacher encouraged me to try out a few sports and eventually I switched to cycling," she said. "I really enjoy it, I love the speed and the adrenaline racing."

Kennedy joined the Parramatta club three years ago and since then has been improving steadily.

Her coach Peter Brooks, a former Paralympian cyclist who won two gold medals at the Athens Olympics in 2004, said Kennedy has shown remarkable progress in a reasonably short time.

"She's worked really hard and has particularly developed in the past nine months and she was just short of breaking the world record in the 500 metre time trail last year," Brooks said.

"She's got a long successful career in front of her.

"I can definitely see her getting to the Paralympics, maybe not in London, but possibly Rio de Janeiro."

Kennedy said the Paralympics is her goal in the long term but she knows she has lots of time.

"I'm quite young for this sport, so I have lots of time to develop."

The Ryde resident finished her HSC in 2011 and was accepted to the Australian College of Physical Education college to study a bachelor of sports coaching and administration.

"It will be great to have coaching to pursue after I've reached the highest level I can get to in cycling," she said.

She also received a 2012 NSW Institute of Sport scholarship, which will allow her to train and use the gym and other resources at the institute.
