But the happy mood turned as the roads in Zhengzhou began to be overwhelmed by the thousands of bikes.
Pictures circulating online showed serious congestion on the main roads from Zhengzhou to Kaifeng. One witness told the local outlet Jimu News that his drive on that route, which usually took one hour, took three.
Some riders shared on social media that they were forced to get off their bikes and push their way through the crowd.
There was no official estimate of the number of bicycles on the road on Friday night. But reports on social media suggest the number ranged from 100,000 to 200,000.
And many of those who made it to Kaifeng didn't seem to have enjoyed the experience.
"I really regret going," said one viral post from a student, who rode more than seven hours. They couldn't get a taxi or a hotel room as the demand was overwhelming.
"As I sat in a restaurant eating my meal, I heard the owner criticising college students for having nothing else to do... I'm really sorry for affecting the people in Kaifeng," the student wrote.
Some users criticised the cyclists for "irresponsible" behaviour such as littering.
As the gridlock worsened, three major bike platforms in China issued a joint statement urging students to use trains or buses for long-distance travel and avoid using bikes at night for safety reasons.
By Saturday afternoon, the companies had begun charging those who rode to a different city.
Multiple social media posts suggest some universities in Zhengzhou have asked students to return to their dormitories and imposed restrictions on them leaving the campus.
Traffic police in both Zhengzhou and Kaifeng closed off some of the main cycling lanes between the two cities on Saturday and Sunday.
It is not surprising to see officials in both cities pushing back because Chinese authorities have always cracked down on large gatherings, which they fear can lead to protests or any form of political expression.
Last month, police in Shanghai silenced celebrations for Halloween over fears the revelries might be used to express dissent.
Ms Li says spontaneous gatherings - such as the Night Ride to Kaifeng - will keep happening simply because they appeal to young people.
"People are so stressed these days, so these events are a good thing," she says. "Because happiness is infectious."
