Bike Diggers/Bicycle Fishers
Amsterdam
Amsterdam is known as one of the most bike friendly places in the world -- it's even claimed there're more bikes than residents -- so it's not surprising that many of said cycles end up in one of city's 165 canals. Waternet, Amsterdam’s Water Authority, employs people year-round to fish out between 12,000 and 15,000 rusty two-wheelers a year.
