There are three main different kinds of bikes. There are mountain bikes, dirt bikes, and BMX bikes. All of these bikes are good, but they are used for different things. There are more subcategories for bikes but, these are standard categories. These bikes are the most common.
Mountain bikes are used mostly for going fast. In most bike races, people use mountain bikes. They are good for travelling too. Most of them are very big, and a bit hard to lift, but their speed makes up for it. These bikes can basically be found at any sporting goods store, or bike store, such as Dicks, or Dunhams.
Dirt bikes are mostly used for riding on rough terrain. A lot of people ride them through dirt, mud, sand, and rocky areas. That is why they have the name dirt bikes, and also because they can get very dirty while riding through these terrains. Dirt bikes are usually motorized aswell. This makes it easier to go through rough terrain.
Bmx bikes are used for doing tricks. These bikes are usually very light, so that you can hop over things and easily flip your bike around. There are many tricking competitions held on these bikes, where people jump off of ramps and do tricks on them. Who ever does the best tricks usually wins. Trick bikes are very fun if you like to do tricks on them.
