It adds a lot of extra pressure on the 10-year-old, but his mum Deane Bearman said he seems to be taken it all in his stride.
"He's definitely nervous about it, there's been a lot of extra attention on him this week but he is coping with it really well," said Mrs Bearman.
Rico was just 4 when he took up BMX after going along to the local track to watch a family friend competing. He wanted to have a go himself, and was immediately hooked. By 5 he was already a national champion, and at 6, a world champion.
What started out as a fun pursuit has become a consuming sport for the entire family. Rico has just returned from a month-long trip to the US with his father, Gordon, a former pro road cyclist, where he was exposed to intense competition every weekend.
In true American style, Rico returned home with some super-sized trophies, including an impressive haul from the US nationals in Las Vegas.
Mrs Bearman said while it was a massive financial commitment to travel overseas to compete, it was a big opportunity for her son, who is determined to compete at an Olympic Games.
"It was a big call to one, pull him out of school, and two, do all that travel, but you just don't get that competition anywhere else," said Mrs Bearman.
"It is an expensive sport ... Every race, every event costs money. But we see it as something we can do as a family as well."
Rico's older sister Mikayla will also be competing today in the 11-year age group.
