Here is a representative sampling of sizes. There are other regular riders (I have the MOST understanding wife!), but this gives you an idea of the range. I don't think I could easily do larger..or smaller.
I notice that the saddle height is similar on those three bikes.
I think a good analogy might be the 'fit' of
shoes.
As long as you can get your foot into the shoe, you can walk to the refrigerator. The closer that the fit approximates a 'correct' size for you, the more you can
comfortably walk/jog/run.
If you plan on doing more than walking to the mailbox or around the block,
a better fit will make a
big difference. Planning on training or running a 10k, half marathon or longer? The 'fit' of the shoe becomes even more important. Some folks need, in addition to the correct size & width, stability- and or motion control in their shoe's construction in order to avoid knee, hip, and/or back issues. Of course some folks are fine with a 'neutral' shoe.
Flip-flops can get you to your car, but you wouldn't want to hike Mt. Whitney in them.
