Du Chakay Duniya (Bengali: দু চাকায় দুনিয়া) (Meaning :The World on Two Wheels in English) is a Bengali book written by the first Indian Globe -Trotter Bimal Mukherjee (1903–1987) based on his experiences of traveling through the world on a bicycle.

He traveled through Arab, Iran, Turkey, Syria, Britain, Iceland, Norway, Sweden, Finland, Russia, Greece, Egypt, Sudan, Italy, Switzerland, France, Denmark, Germany, United States, Colombia, Ecuador, Peru, Hawaii, Japan, China, Hong Kong, Vietnam, Thailand, Malaysia and many other countries before returning to India again in 1937.

He felt very guilty at that time as he loved her, but on second thoughts he again strengthened his mind and set off on the journey.

Thousands of people gathered to wish them luck and hundreds rode with them up to Chandernagore for their first night halt.

They went off Grand Trunk Road then to visit Ranchi to bid farewell to Ashok and Ananda's relatives.

In that jungle they spent a night at an inspection bungalow to experience their first encounter with a tiger.

Bimal Mukherjee could not but praise the guts of the lady, not more than 21 wearing a blouse and shorts looking like a true sportswoman.

But all four of them were unanimous in their decision of not taking the risk of having an attractive young woman as their companion.

They went through Ajmer, Pushkar, Udaipur and Jodhpur thereafter to enter the great Indian desert of Thar.

So they had to carry their cycles and walk over the heated sand all day only to cover a meagre distance of 7–8 miles.

On the way they were plagued with the problem of tyre puncture as the thorns of the cactus trees used to present this threat every now and then.

It took them two hours to cross that enormous bridge over the railway lines carrying the cycles on their shoulders.
