If some bikes are comfortable does that mean the rest are not? (What's a comfort bike?)

To me hybrid bikes are somehere between road bikes and mountain bikes. The tires and wheels are bigger than road bikes but not as big as the truck like tires found on mountain bikes. Gearing on hybrid bikes falls between road and mountain bikes. The frame geometry is designed to allow a more upright riding position. The hybrid is designed for riding and handling at speeds somewhere between the high speed road bike and slogging speed of a mountain bike.
