I can help you with John who can provide you at thivim railway station if Ur looking for Calangute area then there are many which you will find in a walking tour you have to bargain well as this season is now bumper season for goa.happy journey
When you walk on the Calangute-Baga road that runs parallel to the two beaches, you will find bike and car rental shops in abundance. The charges for the vehicle vary based on the model and at times, even from shop to shop. Enquiring at any shop is the best way for you to rent a bike for the price that you want. You can bargain, but if it is peak season, it might be a bit difficult but not impossible 😁.
Renting a two wheeler can cost you anywhere between ₹300-1600, depending on the bike.
Travel safe and hope you enjoy your time in Goa. Cheers!
