The answer to your basic question is yes and no. A hybrid such as the Vita are often characterized as flat bar road bikes. The Vita is a great bike and can do everything you want to some degree. However, if group riding is part of your plan, the hybrid may turn out to be a bit slower than the Dolce because of the hybrid geometry and gearing. That, of course, depends on what kind of groups you ride with, as well as the engine....that is your strength and fitness. I bought my hybrid, Trek FX 7.5, and two months later bought a road bike, a Dolce Sport. Besides the fact that these two bikes threw me into the depths of bike addiction, both are great and both get used for different purposes. Bottom line is no one can tell you what will be best for you. You need to find a good local bike shop (LBS) you like and trust, set a budget, ride different brands of both styles, and see which fits you the best, then you buy the one that makes you smile and want to go out and ride. Enjoy the shopping experience.
