What Is a Mountain Bike?

What Is a Mountain Bike?

A mountain bike is a dedicated bike type that is the most suitable for off-roading purposes. Compared to other bike types, this one has bigger and thicker tires, with flat handlebars, thicker frame, at least a hardtail suspension, and a seating position that is more upright. All these characteristics are to support the cyclist to be able to ride their bike through obstacles with more control and comfort. It enables them to face even the hardest of terrains on their two wheels. To learn more in depth about what a mountain bike is, click here!

The frame is the main part of the bike, the ones that are coated in colorful paints. An MTB frame consists of top tube, head tube, down tube, seat tube, seat stays, and chain stays.
  • The front of the mountain bike : everything that moves according to the movement of the handlebar. Consists of the fork, headset, stem, and handlebar.
  • Mountain bike wheel : what makes the MTB move. The wheels roll around on the ground when you pedal your basikal MTB. It consists of the hub, rim, spokes, tire, and valve.

Now that you are familiar with the terms, let’s learn about what each part actually means.


As mentioned earlier, the frame is the skeleton of your MTB bike, it is where the other parts connect to. The top tube is what connects the handlebar to the seat post. The downtube is the diagonal tube that connects the handlebar to the pedal mechanism. The seat tube is what connects the pedal mechanism to the seat tube. The seat tube is what holds the saddle. The chain stay is what connects the pedal mechanism to the chainring on the rear wheel. Lastly, the head tube is what connects the fork to the handlebar.


The fork connects the wheel to the handlebar. It goes inside the head tube so that the wheels can move accordingly whichever direction the cyclists steer it to. On a mountain bike, the fork is completed with a suspension to further enhance the shock absorbing feature it has.

Handle Parts

The handle parts are the steering wheel. It has the headset which connects the frame to the fork and handlebars, allowing it to turn. The stem is what connects the headset to the handlebars. Lastly, the handlebars itself is the steering wheel that you grip to maneuver the direction of your mountain bike.


The wheels are the one that enables your mountain bike to roll and move. It has a rim which is the part where your tire sticks to. The hub at the center of the wheel that connects it to the moving mechanism. Spokes that connect the hub and the rim (the skeleton of the wheels). Tires which are the rubber part that comes in contact with the ground. Lastly, the valve in which the air you pump goes through to get inside the tire.


The crankset or chainring is where the moving mechanism attaches to and moves the wheels. It is being held down by a bottom bracket where it also connects with the down tube and seat tube. The chain helps to alter the movement of the pedal into the movement of the wheels. The cassette is the different sizes of sprockets which are known to be gear shift options. The shifter is what the cyclists will use to change its gear options. The derailleurs are what helps the chain to move in between cassettes when cyclists change its gear options. The brake is what squeezes the rim on the wheel to create friction and slow down the speed of your MTB bike. Lastly, the brake levers are what cyclists will pull to slow down their speed.

Other Parts of Mountain Bike

Pedals are where the cyclist’s foot rests and transmit their power towards to move the mountain bike. Saddles are where the cyclist will be sitting down on their bike, and the seat post is what holds the saddle on the bike and the part that you can adjust to control the height of your saddle.
