what weight do you think each aspect of a bike ride affects your efficiency or speed? are they all equal, or do so some matter more?

had a slow painful ~20 miles ride with a strong wind last night & started me thinking why did I perform so poorly
for me, last night, I think it was: motor, wind, tires, bike, in that order
the ride took approx. 2 hrs (30 minutes longer than it should have)
