Bike Day also included a grand procession, the best dressed bike competition, sprints and long distance races, and a sausage sizzle to refuel.
The day was organised and run by senior pupils and Year 1 student Jackson Munns said it was "the best day ever".
The school is having an official community opening for the track on April 7 with all riders and their families invited to visit the track and enjoy food stalls and a car boot sale.

Planning, fundraising and construction of the Waikite Valley School pump track has taken more than two years.
The bulk of the funding came from the Infinity Foundation, while contractors from Central Earthmovers and Cooks Contractors built the track over the summer holidays.
Pumice and fill was donated from a neighbouring farm to build the track.
