You can hire a respectable mountain bike from Kaleta in Korcula Town for 50 kuna for three hours. It is a stiff climb into the interior of the island, but even in August you will find the roads fairly quiet. Travelling north to south is easy enough and it is a pleasant sojourn down to the beaches of Lumbarda, but riding east to west is tricky - the roads either peter out or wind all over the place. Wherever you go, you aren't far from the coastline or a fine view.
