What are the most expensive bicycles around the world! Coming in first place is the Trek Butterfly Madone which costs around a whopping $500,000! You can definitely buy a good sports car with that price tag. This bicycle is an artwork by Damien Hirst and it was bought at an auction for that price. Although it’s beautiful, some animal rights activists called it barbaric due to the fact that the bike utilized real natural wings from butterflies. This Butterfly Madone was sold at an auction to raise funds for the Lance Armstong Foundation.
