That's decent gearing. My daily ride is 63 and I'm wanting it to be a bit less. I have a different chainring I might try out on it and it will be closer to 55. I do this one ride where the grade is a just a bit too long of a gradual uphill and it kicks my butt when I do it with my cruiser. I do it with our other bikes with gears and it's a lot easier to do. LOL.

I'm thinking 55 is just about the perfect all around one gear gearing, but I need to test that theory. My first cheap BMX bike is like 46 and it's just way too short. I don't like riding it any amount of distance. It's just annoying.
