Teacher bikes to help slum kids

Every day, Aditya Kumar cycles about 65 km with a heavy load of books and his few possessions on the back of his battered old bike to bring education to India's slum children.

The science graduate has dedicated his life to teaching in the slums of Lucknow, a sprawling city in northern India that is home to some of the country's most deprived communities.

He takes no money for his lessons, which he gives all over the city.
