Hi, This is to recommend a good place to rent bikes in Pondicherry. I recently hired one. You can get in touch with Mr. Joshi (VIJAY ARYA is the name of the establishment). They are located at No.23, Aurobindo Street, Pondicherry - 605001 (Mobile number: 9345425099). This is in the heart of the town, when u are there do ask him how did they start? He told me the story!, but don't ask me, ask him when u are there! If you want you can also get a Helmet for hire (Rs.50), I did hire one but I discovered to my amusement that I was the only person using it in the whole of pondy and auroville!!! have a nice time there!
