Which of the Kerama Islands is the best to cycle around?

I tried using the steet view to see which of the island would look scenic to cycle around. I noticed on zamami near "Marilyn the Faithful Dog" statue the road is very picturesque for cycling. is this my best option? or is there any other island I can visit for a similar or better route?

also if there's any suggetion for electric bike rental places that would be the best!
