Go with the Big 4: Giant, Specialized, Trek, Cannondale. They offer the greatest selection of sizes and components to suit virtually any taste. Once you get more experienced in cycling and know what you like/dislike, then you can expand more confidently and move on to more exclusive cycle manufacturers should your taste lead you in that direction.
