Public bicycles
Public bicycles are provided by the government of Kaohsiung city. This is a good policy that makes it convenient for citizens and visitors to get somewhere if they don't have a scooter or car [or: This is a good policy that makes it convenient for you to get somewhere if you don't have a scooter or car]. Bicycle rentals are free for the first hour if the user has [or, if "you" is used in the last sentence": if you have] a registered card or credit card. It is very suitable for travelling short distances.
Public bicycles stations are mostly located at or near the MRT stations, so you can take the MRT to the station close to where you want to go and then ride a public bicycle to your destination. I think this would save time and reduce the air pollution from scooters or cars.
