Motorbike is throughout the year a fine way to get around in the south of Greece.
So in case you haven’t brought one with you, there is always the chance to rent one.
I suggest my dear neighbour Bastakos. A nice fellow who is dedicated to selling and repair motorbikes and has his son running the renting business.
Notice though that since 2018 Greek authorities got a lot stricter with chasing after rentals and so nowadays one needs to have a valid motorbike driver licence in order to rent anything. An exception to this is made for the electric motorbikes which are meant for small distances within the city.
