Do you want to ride on paved roads or do you prefer off-road technical trails OR would you rather a combination of both.
There are lots of types of bikes however for purposes of this guide we are going to talk about four in this section.
Mountain Bike. This bike is used for riding on gravel, dirt and rough terrain. Typically you ride this on trails in the forest and mountains hence its name. You can get one that has suspension in the front or in both the front and the back. The suspension helps aid in keeping the wheels on the ground and smooth out the ride for more comfort.
Cyclocross Bike. Like the hybrid this bike is used for riding on paved roads as well as gravel trails. It looks like a road bike only it has disk brakes like a mountain bike and nobbier tires. This bike gives you even more options than the hybrid in that road bikes and cyclocross bikes can ride together in groups.
Once you decide on your bike, they are also going to inform you that, depending on which bike your prefer, you will also need to buy pedals and cleats for the bottom of your cycling shoes.
They are also going to ask you whether or not you want to buy water bottle cages to put your water in. These attach to the frame of your bike.
All of these items are recommended and DO NOT come with a bike so when they ask the question, it's legit.
