Start with the frame, reasonably the most crucial mountain bike part. The frame is the backbone of your mountain bike and the most considerable part of your bike, which joins all other parts together. A reasonable frame is something that sets any mountain bike apart, so you should spend some money on it. Once you buy a quality frame, it will last years. You can find mountain bike frames in two different materials commonly. Aluminum is light, solid, and the most affordable material, making it the most popular frame material. Another one is carbon which is also strong and light with the additional benefit of being shock-absorbent.

The one part you must know is the rubber tire available in a wide range of sizes based on the terrain of your mountain bike. Then the tire has a connection with the wheel’s rim, the outer hoop of the wheel. Just like the frame, the most common material of wheel rims is aluminum. The inner tire valve you use to blow up the tire sticks from a small hole in the rim. The center part of the wheel is the hub, which contains the ball bearings and an axle. 

Pedals, Cranks, And Bottom Bracket

When you push them, the cranks and pedals make the chain spin and move the bike forward. The pedals are attached to the cranks having a connection with the bottom bracket. The bottom bracket is where the seat tube, down tube, and seat stay come together. It contains a spindle and a bearing that allows the spindle and cranks to spin.
