I saw a Ritchey makes a new road bike that is able to fold it. The bike is the standard diamond frame when it is unfold. Why don't the companies make foldable bicycle? Another company who make good folding road bike is Bike Friday. Again, it is just not popular compare to Trek, Cannondale... I wonder why people don't ride the foldable bike since you can easily store it in the four-door sedan automobile or even in your room. Are they given the same comfort and weight as the unfoldable one does? Any ideas?
