The usual mountain bike riding kit is a muddy riding top and baggy shorts, but this Sunday expect to be wowed.
Following on from the 2010 Singlespeed World Championships in Rotorua where hundreds of riders raced in costume, there is Pimp Your Ride in the Government Gardens, a cartoon character-themed family fun ride and then the parade in the city centre after the Criterium racing.
The family run ride meets at the Waipa MTB car park but dressing up is not compulsory. Rotorua Mayor Kevin Winters has already scoped out his costume and is looking forward to the festivities.
"I've got a superman costume," he said.
"He has a cape and a cape looks really good on the bike, flowing out behind you.
