SHANGHAI - A set of industry standards was released Wednesday to regulate China's bike-sharers who are driving an already massive sector which is highly competitive, crowded with rival players and rapidly evolving.

The cities of Shanghai and Tianjin have drafted regulations to take effect on Oct 1, after taking advice from bicycle manufacturers and bike-sharers.

Bike-sharing companies, including Mobike and Ofo, will adhere to standards on production, operation, and maintenance of shared bikes.
