I think knee over pedal spindle is baloney.
Your saddle might be too high or low.
Your saddle might be too far forward or back.
Your cranks may be too long. What length are they?
How old are you?
What is your approximate pedal cadence (RPM) when riding on flat ground? Up hills?
Do you have pictures or video of you on the bike? They will help!
