Spring is here, so it’s time to look at bike options for the season. Recently luxury car company Bugatti has teamed up with German luxury bicycle manufacturer to create the ultimate special bike. The last time these two collaborated they created a project priced around 39,000 U.S. dollars, so probably the priciest bike in the world. Weighing less than 5 kilograms the bike is said to be the lightest in the world, using materials found only in motorsport and aeronautic industries so the lightest weight and highest rigidity are guaranteed. PG and Bugatti only created 667 units, so at 39,000.00 a pop that is quite a haul.
