Bike Parts: Different Components in a Bike

Do you remember when you got your first bicycle? You must have been 2-3 years of age. This means you have been familiar with bikes for quite a long time. So can you name all the various components of a bicycle? Your answer is probably no! Nobody would be able to. However, understanding the bike parts is crucial if you use them often. Here is the list of essential bicycle components that you should know. Continue reading!

Main Components of a Bicycle


The frame is the central component of a bike on which all other elements are mounted. The frames are built with sturdy and robust materials like steel, aluminum alloys, titanium, carbon fiber, thermoplastic, magnesium, and scandium. Today, bike frames are available in multiple designs, thereby allowing you to choose one that fits your activity and height.

Seat post and saddle

As the name suggests, the seat post is a component that holds the saddle (the seat where bikers sit). Just like frames, seat posts are made of different kinds of materials. If you plan to replace your seat post, make sure the one you choose is compatible with your frame’s seat tube. However, you don’t need to look for compatibility for a saddle as all kinds of saddles fit all seat posts. But, don’t forget to choose a comfortable saddle.


Earlier, the bicycle wheels were made of wood or steel, but after the invention of pneumatic tires, bike manufacturers switched to the modern lightweight wired wheel designs. A wheel comprises a hub (houses bearings, axle, gears, more), spokes, rim, and a tire.

Stem and handlebars

The stem is the part of a bike that attaches the steer tube to the handlebar (what you use to steer the bike). The steer tube and the handlebar are connected to the frame via the stem that helps control the bike. When buying these parts of your bike, make sure they are compatible so that you get the perfect fit. Moreover, you have a gamut of choices for handlebars to choose from. For mountain bikes, urban bikes, and hybrids, it is advisable to go for flat handlebars. On the other hand, drop handlebars are an excellent choice for road bikes. However, there are many different styles too.


There is a countless variety available today when it comes to bicycle brakes. Yes! You might think that all brakes are the same as they perform the same task. But for manufacturers and bike connoisseurs, these are different. There are spoon brakes (rarely used today), duck brakes, rim brakes, disc brakes, coaster brakes, drum brakes, band brakes, and drag brakes. Many utilize actuation mechanisms, while some are hydraulic and even hybrid.

Crankset and bracket

A crankset/ chainset is one of the essential bike parts that your legs push around to turn the rear wheel, and the bracket is the part that connects the cycle to the crankset. The bracket has a spindle with which the chainset is attached and enables the crankset to rotate. A crankset consists of chainrings (on which chain goes round) and the crank arms (where the pedals are attached).


Now comes pedals! These are the spinning interfaces between the bike and your feet. The components of a bicycle you push down to move forward when riding a bicycle are called pedals. These are of two types- flat/ platform pedals and clip-in pedals. You need to wear special shoes with cleats in their soles for clip-in pedals, while flat pedals rest your feet.
