>>1315378>>131537690% of the time most cyclists are going in a -relatively- straight line. The recumbent bicycle is thus optimized for 90% of cycling. The bent-forward bicycle is not optimized for straight line cycling. One, it experiences more wind-resistance, second, the ''saddle'' is not made for prolonged seating. Note; I put saddle between quote marks, as bicycle saddles are in fact perineal pressurizers.
So where does a bent-forward bicycle excel? In places that demand high maneuverability. It is true there are times when the bent-forward bicycle is a better tool for the job. But why should we ride bicycles that are optimized for only a small part of cycling -in general-.
