More colors keep being added to China's bike share rainbow, so naturally the next shade to be added was... rainbow. (Because 'tuhao gold' wasn't enough).

Over the weekend, Beijing cycling enthusiasts were treated to a new fleet of colorful shared bikes, which come in seven different designs and colors: red, orange, yellow, green, blue, indigo and purple. 

"Qicai Bikes" have also made their way down to the 'Hai, where they were spotted at certain spots around the city earlier this week. The light frame, soft-saddle bikes have smart locks and are available with a deposit of RMB99. 

Oh, and they've also got glow-in-the-dark wheels. 

The bikes will soon appear in Guangzhou, Shenzhen and Nanjing.
