--FILE--Damaged bicycles of Chinese bike-sharing services Mobike (orange), ofo (yellow) and Xiaoming Danche, or Xiaoming Bike (blue) are piled up near Xiashan Park of Shenzhen city, south China's Guangdong province, 16 January 2017. Main cities in China have seen an explosion of colorful bikes that users can easily ride or park using a smartphone app. However, such bike-sharing schemes are facing various challenges, including vandalism to parking chaos and a lack of supervision. Bike-sharing is regarded as a way for large cities to reduce congestion, cut air pollution, improve health, and also perhaps spin a profit for start-ups. However, statistics show more than 10, 000 sharable bikes have been damaged in various ways ¨C such as bikes being painted or key-like QR codes interfered with. A recent news report said a hacker was able to unlock a bike in five seconds by taking advantage of a technical bug, although usually the cost for one ride is as low as one yuan (.14). It's also reported that some bicycles have been thrown into ditches, left parked in the middle of roads or driveways, or had seats or other parts stolen.
