The world's most expensive and eco-friendly push bike has been made public and is on display at the Lentos Museum of Art in Linz, Austria.
The 1.9-million-dollar "Fahrradi Farfall FFX" with a top speed of 16 km per hour, is the brainchild of Austrian artist Hannes Langeder, News.com.au reported.
But rather than using V12 horse power, the "car" operates with pedals where the accelerator and brake would be in a normal car.
