A man named Warren Gregory (50), originally from Florida, US, has beautifully decorated 300 bikes in Amsterdam, Netherlands. Gregory is known in the city as the Flower Bike Man.

The man started doing this when his wife lost her bicycle. "I knew from being in Amsterdam that if you lose your bike, you decorate it. The first one I made was with sunflowers ", he says in the video.

After creating a new beautiful bicycle for his wife, Gregory decided to do it for other people too. When businesses realised that so many tourists were taking pictures of his bicycles, they saw a big opportunity in having them inside and outside their shops.

Gregory's bikes have also become a colorful spot for homeless people to collect their meals.

You may have seen these flower-decorated bicycles around Amsterdam, but do you know who's behind them and why?
