You could not go wrong with a Trek DS as your first hybrid bike. Belt drive, sealed bearings, comfy and super versatile. It can do everything from neighborhood strolls with the the kids to 50 mile (or more) fitness rides.

These bikes are great in the winter too. After a dirty ride, just hose them down, dry off and they are ready to go... The only problem though is that they aren't cheap and if you ever get a flat tire, removing the wheel on a belt drive on the side of the road can be a challenge.
