The bike sharing phenomenon is getting bigger and bigger. Barely one month after the introduction of the government-funded public bikes and Mobike were introduced, two more companies, ofo and Ubike, appeared in bright yellow and green, respectively, have entered the fold. The biggest advantage of the latest offerings is that you can simply unlock and rent them through their official WeChat accounts, though they also have an English-friendly interface in their apps. The deposit for ofo is as low as 99 RMB and compared to their orange brother, they seem to have better designs with adjustable seats, a rear fender and even a basket. However, with tens of thousands of bikes spinning around the city, parking is becoming a concern. In Shenzhen, the government has already been removing some of the improperly parked bikes from the streets.
