Authorities impose restrictions on bike hire after huge group blocks a highway between Zhengzhou and Kaifeng in China, as night biking trend takes off
A night-time cycling trend that started with four Chinese students riding 50km for dumplings blew out to a reported 100,000 people on Friday, jamming major roads, overwhelming a small tourist city and drawing the attention of authorities.
The pack of students, mostly on public share bikes, rode several hours through Henan province from their campuses in Zhengzhou to the ancient city of Kaifeng.
