Hybrids are great. For those of you unfamiliar with hybrids they've also been called city or commuter bikes, and could quite possibly be one of the most efficient bikes ever made. Pretty much a mate between mountain bike style geometry, with road bike efficiency.   They're a perfect way to go back and forth to school, commute to work, run errands, or just ride around the neighborhoods.  This style of bike is so versatile, it's easy to see why so many people are hopping on these things to beat the traffic.
