Bikes designed for road use, as opposed to mountain bikes. They are geared to operate on flat areas, and therefore suck for going uphill (but are great for downhill). The favorite bike of spandex wearing pansies. I use a road bike for commuting and paved roads and a mountain bike for dirt roads and very hilly areas. Under no circumstances do I wear spandex.

I wonder if I should take the gears off a mountain bike and put them on my road bike.
