Although the infrastructure for cycling is almost non-existent, it is of course possible to rent-a-bike to at least see the city landmarks and monuments, or beach hop from one to another of course. There are a few bike stores around town that charge around 100kn per day and if you choose to rent for a few days in a row, the price is then discounted.
Option two is the Nextbike system where you can rent and return a bike at any one of four city locations. The initial amount you pay is 79kn and that amount is used as credit for bicycle rental. Each day users have a 30-minute free ride available and if you surpass those 30 minutes; then there is an additional 8kn hourly charge (www.nextbike.hr).
