Write a letter to the municipal commissioner of your city to promote the use of bicycles in th e city.

Here is a sample for your reference:

25- A,

Circular Road

Vijay Nagar

Delhi 

8 October 2012

The Commissioner,

Municipal Corporation of Delhi

New Delhi

Sir,

Subject: Request for increase in usage of bicycles in the city

On behalf of the citizens of our nation, I wish to draw your attention to the problem of pollution in our city. A solution to this is usage of bicycles in our everyday life. The exhaust gases from the cars and bikes are increasing the problem of asthma and stress here. 

Every person here owns a car. Every member of a family drives everyday, rather than adopting the idea of car pooling. This is also making people sloth day by day. They walk to their school, colleges, institutions and offices, sit there the entire day and come back the same way. Riding bicycles would keep people hale, hearty and healthy.

Considering the problems faced by us on regular basis, I request you to make the necessary arrangements for promoting this idea. Your efforts would be much appreciated.

Thanking you in anticipation for your kind cooperation.

Yours truly,

Vinay Aggarwal
