We hired an electric scooter a few years ago from
marmaris rentals. They bring it to your apartment and collect it from there at the end of your stay. At that time we didn't know about the Buffalo bar but two years ago we hired an electric scooter from him for a week when we had a problem with ours. Incidentally, ours was repaired by a kind gentleman in the old village before we returned home.
I recommend both marmaris rentals and the buffalo bar but marmaris rentals is more expensive and would use them again if there weren't any available at the buffalo bar.
