Megan Williams, 10, is ranked second in the world in the girls' 10-year-old competition, while Jeanette Davies is ranked third in the over 30-year-old women's cruiser class.
Rotorua BMX Club president Melanie Short was excited about the group's prospects on the world stage.
"They've had some great racing the States in the warm-ups to the worlds and they are on track to represent New Zealand well in their age groups. They've all got really good potential," she said.
The club's strong contingent was due to having a strong presence in the Rotorua community.
"We've got a really good club and track in the middle of the city that is used by both club members and the community," she said before hinting at possible changes in the near future.
