I used to ride a motorcycle in addition to the bicycle.

When you're buying a sportbike, do you know how many choices of the frame size you normally get? Exactly one (1), also known as "take it or leave it". On a motorcycle, you don't need to pedal but other considerations, like aerodynamics, handling, etc. are pretty much the same.

Eventually I grew resigned to the fact that I can't put my feet flat on the ground at the same time on any sportbike in production, because they all had seat heights at least a couple of inches higher than my leg length, and said heights were not adjustable in any way. At stoplights, I had to lean the bike and touch the ground on the outside with my toes. (This, by the way, is a somewhat bigger problem on a motorcycle, because even the lightest sportbike weighs ~450 lbs including gasoline and battery, and lifting a dropped bike is hard, not to mention embarrassing.)

Compared to that, worries about having to find a "perfect" bicycle frame size among 8-10 options seem laughable.
