Which island? Any bike the right size in your price range would do.

I'd get wider road-tread MTB tires for better on-road behavior. I run fat 1.95 slicks on mine.

A good rigid alloy rear rack of any brand would do, and search on folding pannier baskets or "grocery panniers." Lots of those out there.

Lots of good fenders out there, too. I have ESGE (now SKS, I believe), Blumels, Zefal and Planet Bike on my bikes. All good.

Good luck. Post pix when you arrive.
