This three - part series illustrates how the bicycle is used today and what impact it has on people's lives.
With more than a billion models worldwide, the bicycle has found a place in every society.
Since its invention in 1817 people have redesigned and used the bike for hundreds of different purposes.
From sporting events and policing the streets to sharpening knives and selling ice cream.
Using a lot of leg power, the Bicycle Diaries journeys into three different places around the world to discover the communities and people for whom two wheels are better than four.
Rupa Jha introduces a montage of voices who talk about why peddle power matters in New Delhi, India.
Here, the bicycle is fundamental to one of the city's essential economies - the newspaper delivery industry.
At 5:00 every morning, hundreds of newspaper deliverers gather with their bicycles in bazaars, ready to deliver the day's news.
The programme features deliverers who take us on their route across New Delhi. They share stories of what impact the bicycle and their job has had on their lives.
For one 19 year old it is a way of funding his studies, and for another deliverer the income has helped to support his family.
