Police said one person had received "minor injuries".
"All the bomb blasts have happened in one locality and it does not seem to be a terrorist attack, rather it seems to have been a mischief-maker," Pune police commissioner Gopal Rao Pol told AFP by telephone.
Police said the explosions were low-intensity.
One of the bombs was placed outside a McDonald's fast-food outlet while another was attached to a bicycle, police said.
The blasts came as India's new home minister, Sushilkumar Shinde, officially took up his duties after being given the key portfolio the previous day.
Police cordoned off the areas where the blasts occurred.
In February 2010, a bombing at a bakery in Pune frequented by tourists killed at least nine people and injured 57.

These were tiny blasts with almost no casualty. So ISI involvement very unlikely, they usually go for big ones.
A low intensity blasts means that its a sign that they have done their preprations ready for a high intensity blasts on another city
