Criteriums are urban races where participants ride their bikes to spin and complete a established round. Such events use to be done at night because of less car traffic and are popular among fixie bike lovers. Racers highlight adrenaline rush as a motivation in these races that are presented in lots of cities.

A special case is Singapore. In 2013, the first criterium took place there thanks to the tenacity of Zul Awad. Eric Khoo Shui Yan helped him and Holy Crit was the race name. They organized eight races up until November 2014 on closed roads or with little traffic. But also without the required permissions. Authorities fined them even if they explained them their unique objective was to increase the number of bikers. They did not receive any payment, nor did they have sponsors.

Ding Jie Ng, a young producer, noticed their troubles with justice and felt the need of telling it to the world. Thus, he made a documentary, Fixied, with little resources and inspired by the criteriums. As a results, he filmed a documentary with the help of Zul at night which is worth it from a cyclist and human perspective.
