This type of bike is extremely light and made for speed. Sometimes these bikes are referred to as racing bicycles. They are meant to be ridden on paved roads and are built to be ridden frequently and for long periods of time. The tires are quite skinny to help minimize road resistance and provide more aerodynamics. A big difference from this bike to others are the handlebars. Road bicycle handlebars are dropped to allow the rider to lean forward, creating less air resistance.
