I see (non) bicycle riders all the time that ride with the seats way to low for efficient use of their leg muscles. I mentioned it to a gal passing my house two days ago and she allowed me to raise her seat a great deal. She was amazed at what a positive difference it made. She was very happy with the improvement.
That makes a difference. My impression is that bicycles are designed for racers and people who want to be mistaken for a racer. I've always preferred the sit-up-straight, easy-to-pedal styles.
