My criteria for a bike riding around on the streets aren't too complicated but not always easy to fill.
Spoken like a road cyclist. Who is aware what geometry a bike needs to work optimally under him. As well as how to make something in that range fit him. Getting the seat relative to the pedals and bar distance/height right can still produce an unrideable or unsustainable position.
I'm on the edge of both issues with manufactured bikes. When you throw a 140mm-150mm stem on any bike designed around 110mm-120mm things get interesting. Especially on 1" threaded forks using a quill stem!
