A roller coaster-themed bus on route 194 in Hangzhou, East China's Zhejiang province, went viral online these days, for providing roller coaster-like riding experience in the city's iconic scenic area West Lake.

The bus's exterior design features a backdrop of blue sky and white clouds, with two mascots riding the roller coaster.

Passengers have also discovered small surprises on the windows that closely match the curvature of the bus body, illustrating the "roller coaster bus" navigating the highs and lows of crossing bridges. Many joke that this is Hangzhou's very own roller coaster, offering an unbeatable cost-performance ratio at just three yuan.
