Wrinkled clothes are another often used excuse. The desire to where stylish cloths and present a professional image while on the job is not unreasonable. Letting that desire rule the rest of your life is. Many men and women voice this concern, perhaps because, for someone who does not ride regularly, even five miles is enough to work up a sweat, especially if you're late for work. The bicycle industry only recently has discovered the difference in relative proportions of body length above and below the belt in men and women.
Women tend to have longer legs and shorter torsos than men.
This means the bike has to be shorter from seat to handle bars, which leads to design problems such as the front tire overlapping the pedals. This can be dangerous, so bikes are generally not designed with the required short top tube. As a result many standard bike frames are a poor fit for many women. Other companies have tried other means, to make their designs a better fit for women, with varying success. Those days are gone.
