Kimolos is a small island in the Cyclades.
The best way to get there is to go to Milos and take the "Pantoffla", a small ferry going from Pollonia(Milos) To Kimolos 3-5 Times a day (20min, 2€/person, 2.6€/motorbike). Some of the big ferries going to Milos also stop in Kimolos. Ferry schedules can be found at 
There is no car or bike rental on Kimolos. Go to Milos, rent one there and bring it with the ferry. Be sure to ask the rental if it is OK to take it. Cars are usually not a problem, but with bikes a lot of the rentals don't allow so. At least Easy Moto and Niki's don't make a fuzz of it, but be aware that if the bike breaks down on kimolos it is your responsability to get it back on the ferry to milos.
