If you´re looking for the cheaper way to travel all around in Bali, you might know that taxi is not the right choice for you. I´ve visited bali many times with my husband and we have already tried taxi, rent a car, and also rent a motorcycle/scooter. Motorcycle/scooter is the cheapest transportation because the price per day of the rent is only idr 75k while for car start from idr 450k (including the driver + gasoline). You can easily find place to rent motorcycle/scooter in bali. It´s very important to check the condition of motorcycle/scooter before you decide to rent it. Make sure that the brake, mirrors, wheels, and the horn are all in the good conditions. Always try to get the new scooter (has one-two years old) and the price of new scooter starts from idr 75K. They may offer you with lower price for older scooter but it´s better to rent the new one. Some of them have delivery service and i always prefer that. It´s not complicated to rent a scooter actually, they will only ask your name, passport number, and the room number of the hotel where you stay.
please leave your questions on the comment and i´ll help you out.
