I ride 5 speed and single speed vintage Schwinn cruisers. Dont let anyone poo poo riding beach cruisers as it is not exercise. I ride mine year round and go 16 to 40 miles at a time,,,riding a 35 to 60 pound cruiser is much more of a workout than riding 30 miles on a 18 pound road bike. I used to and sometime do ride road bikes, I just find cruisers much more fun. You see more of the scenery being upright and same for the safety issue, you see better what is coming at you.
Here are pics of bicycles me and my wife ride, though she doesnt ride as much as I do.
