          Wheels on a bike

Description

The wheels on a bike are circular objects that rotate on an axle that allows the bike to move efficiently on the ground. Bike wheels are not only used for bikes but they are often attached to a box or any type of holding container to make transportation of heavy objects a lot easier for those who work jobs in high manual labor like construction and engineering. 

Purpose

This technical description is for those who have an interest in mechanics, engineering, or anyone who is interested in building or constructing. Bikes are often seen as the best choice to start when it comes to constructing and bike wheels are very simple to understand. Gaining the basic understanding of a bike wheel can give you an idea on the process of other types of wheels. For example, wheels on a car, wheels on a toy, wheels on a crane, and even the wheels on an excavator because they all have different structures.

External Components

There are 4 external components that are the parts that we can see from a completed version of a bike wheel which are:

• Sensor Nipple

• Tyre 
• Rim 
• Spoke

Sensor Nipple

This part of the bike is used to let air in and to keep the air inside. The Sensor Nipple is meant to be twisted open and pumped with an air pressure of 80-130 PSI which is the necessary pressure needed for a bike to be able to function on the road.

Tyre

This part is the part we all see and this part of the wheel is the foundation of the wheel which keeps all of the air in as well as keeps some of the internal components safe/intacted. The tyre also is what allows the bike to run more smoothly. 

Rim

The rim is a large hoop that is attached to the outer part of the spokes and the tyre. It acts as a casing for the spokes and the bottom part of the tyres. 

Spoke

The spoke is a bar/rod made of stainless steel with a purpose of adding support and keeping a balance for the Tyre

Internal components

There are two internal components that are only seen when building the bike wheels or when taking it apart. These components are 

• Free wheel
• Inner protective tube

Free wheel

The free wheel is the part of the wheel that allows bikes to propel forward when pedaling.

Inner Protective Tube

The inner protective tube is a rim tape that protects the inner tube of the bike from holes or sharp objects so that the bike wheel does get punctured easily.

Conclusion

To conclude, the bike wheel is composed of numerous inner and external components that all work together to allow an efficient momentum for bikes.
