The ride will start with coffee at one of the city's iconic tourist attractions, Te Puia from 9am to 10am.
Rotorua Singlespeed Society president Gary Sullivan said the one-lap course would be over some of the best the Rotorua Trails Trust and Rotorua Mountain Bike Club offered in the Whakarewarewa Forest including part of an awesome new loop of the forest.
The ride ends at Secret Spot Hot Tubs at the Waipa MTB car park with a sausage sizzle and a beer from Good George Brewing.
"Secret Spot has become a favourite destination since launching last year," Sullivan said.
"A combination of a tranquil location and soothing hot waters that Rotorua is world famous for."
The finale of the day will be at the Pig and Whistle Historic Pub who have partnered with the Society since 2008.
"The perfect after match location for any singlespeed event is a pub," Laing said.
"We'll have a prizegiving hosted by our long-term MC, Rawiri Bhana, with swag from Jeffson Bikes, Dancing Moose, Whakarewarewa Pest Free, ZORB, Velocity Valley, Secret Spot, Mourea Coffee and Kartline at Off Road New Zealand.
