Emma Finnegan from Liverpool was a skateboarder until she started trying out people's bikes at her local park and got hooked on BMX. Now she's a GB athlete at the age of 20.
"It's a pretty amazing feeling to be a part of British Cycling - especially at 20," she BBC Sport. "And British Cycling welcoming BMX cycling on to the programme is pretty epic."
Like other BMX riders, Finnegan is always looking for the next trick to master.
"Just knowing that you’ve achieved that next thing you wanted to do, then putting it in a routine in contest, is what pushes me to learn new tricks."
With friend and co-GB rider Charlotte Worthington sidelined in Chengdu with concussion after a crash, Finnegan is aware that urban cycling can be a hazardous game.
"I think dealing with injuries is part of the learning curve," she said. "It’s about pushing yourself in the first place so injuries can happen – and it does happen in a sport like this – but it’s not the worst thing in the world.
"And now having British Cycling looking after us gives you extra confidence."
