We spend money to fulfil one of our needs. Before this, we should understand the need and priority of the expenditure on it.
 If you can get your needs fulfilled without incurring that expense, then save that expense. 
For example, a relative of mine used to live in an area where no automobiles passed through, so he had to walk 3km to catch public transportation to work. It was his compulsion at that time, but he accepted it for the sake of his life. 
Time has also changed, and cabs on call are available, but due to his experience, he does travel on foot to transport instead of hiring a cab or taking another vehicle, and this saves his travel expenses.

He saves money and do his daily walk at the same time, it is a win-win situation
There are small things that we can do on a daily basis that can save us some money, if we pay attention to our daily routine we will surely find ways to save.

I no longer need to leave home to earn (thanks to the Internet), so my daily routine includes finding more time to focus on finding what pays more than the few I use now and watching my daily pay slowly increase over time. As long as it is always going up, I am happy with that direction.

I too do all my travelling with my bicycle which saves me fuel cost and also its environmental friendly

I totally agree whatever will help you save money and will not be detrimental to your health then one can go ahead with it.
