Road Bike
The primary use of bicycles remains their ability to effectively transport people around their city or town. If this is your purpose, a road bike is your best option, as it is designed to excel on paved surfaces. The road bike can accelerate quickly, it brakes well, and if you take care of it, it can potentially last for years to come.
Again, if riding around town is the kind of biking you are looking to do, the road bike is what you should be looking for. The road bike features lightweight frames and skinny tires. They have a shorter wheelbase and an upright shape, which allows for easy maneuverability once you get up to speed. The design, along with the drop handlebars, positions the rider in an aerodynamic shape.
In fact, a basic road bike and some safety accessories and you should be ready to get started on everything you need. As you get a better familiarity with your bike, you can determine what customization options you might want to consider. And, of course, if you will be riding in the mountains or on off-road terrain, you might want to look into a mountain bike or a BMX bike.
