Traveling around Naoshima - bus, bike, foot?

We (70s yo couple) are planning a trip next November to Japan and looking to stay in Takamatsu for several nights. We want to tour Naoshima for a day. I don’t think if I’ll feel comfortable renting an e-bike. How manageable is it to use public transportation or a regular bike and walking? What would you prioritize seeing since I doubt we’ll be able to see everything.

Thanks! This will be our second trip!

Transport
- walking only isn’t really an option. The island is small but not THAT small that you could walk from the ferry to the major attractions
- cycling : is a good option however the bikes are mainly Japanese mamacharis. Heavy bikes with few gears and very low seats and the island is somewhat hilly. If that sounds okay. Then cycling is probably the easiest way to get around as you don’t need to wait for the bus an md you can go to non-art related areas of the island
-e-bike: not sure why you exclude it. It’s very similar to a normal bike just a bit more expensive and gives you a bit of an extra push uphill. But these aren’t fast by itself.
- bus is explained here https://www.japan-guide.com/e/e5476.html

My highlight was the Lee Ufan museum but when I went the Chichu museum was closed.

I have done the day trip from Takamatsu several times and it is easier than from (say) Okayama.
My recommendation is bus to the Art House area and then walk around there followed by bus to the Benesse sites, and then more walking.
It is possible to walk everywhere with enough time, but not very practical.
My other tip would be to take food - getting something for lunch can be a challenge. My last visit we ate at the Benesse House Museum Cafe - it was ok (limited menu).

oops, other comment, have 100 yen coins for the bus.

Thank you both! This is very helpful.

I’m mostly concerned that I might get hurt while riding the e-bike, but perhaps that’s not really an issue. From what you describe, the regular bikes are not an option so I’ll definitely consider an e-bike.

If you are used to ride city bikes there is nothing to worry about the e-bike. If you are a (semi) regular cyclist a normal bike will do though.
