I'm sorry I missed this thread before. I would have advised a one-speed for a cruiser bike; just keeps things much simpler, especially with salt air, sand, etc, but obviously only works if the roads are flat. Not all beaches are. I loved my single-speed beach cruiser in Belize and would have had no need for gears, which just add weight and complexity. If I had needed gears for hills, I would probably have gone with a hub just because of the sand. But we were riding on the beach, and that makes for a real mess. Not to mention riding through deep puddles on the road during rainy season. The fewer parts to get glommed up, the better!
I want to see photos!
