BY THE END OF 2016, the number of bike-sharing app users in China had reached 18.9 million and the market continues to grow. However, problems have emerged that call for more attention. Thepaper.cn comments:

Bike-sharing is flourishing in China, but as it has grown problems have emerged. Many people just leave the bikes anywhere, without giving a thought to whether they are causing an obstruction.

Some of the bikes are locked by selfish users so others cannot use them. Fraudsters even glue a payment code to the shared bikes so people who mistakenly scan them transfer money to them rather than the bike-sharing company.
