Hybrid, The Versatile One
A hybrid is exactly what it sounds like – a mix of a road bike and a mountain bike. The result is a bicycle that's suitable for general-purpose riding over various types of terrain, which is why most hybrids tend to be used for commuting.
If you want something that performs well on the street but can also handle some unpaved terrain, this is your bike. You might also see hybrid bikes referred to as "fitness bikes" because their comfort and versatility appeal to riders motivated primarily by the exercise benefits of riding.
A tipoff to whether a bike is more for street riding is the absence of suspension. Hybrid bikes with front suspension are a good choice if you plan to spend more time off road—the tradeoff is a bit more weight and a little less speed in exchange for a cushier ride.
You can use it as a commuter bike during the week, ride for fitness after work, and explore new routes on the weekend.
