Bicycle
A **bicycle** is a human-powered, two-wheeled vehicle that has been used for transportation, exercise, and recreation for more than a century. Simple in design yet extremely versatile, bicycles play an important role in daily life all around the world. They are affordable, environmentally friendly, and suitable for people of almost all ages.
At its core, a bicycle consists of a **frame**, **two wheels**, **handlebars**, **pedals**, **chain**, **gears**, and **braking system**. The rider powers the bicycle by pedaling, which turns the chain and rotates the rear wheel, allowing the bike to move forward. Steering is done through the handlebars, while speed and control are managed with pedals and brakes.

### How to Use a Bicycle
Using a bicycle begins with proper setup and safety. The **seat height** should be adjusted so the rider’s legs are slightly bent at the lowest pedal position. The handlebars should feel comfortable and allow easy control. Before riding, it’s important to check the **tires**, **brakes**, and **chain** to ensure everything is in good condition.
To ride, the cyclist mounts the bicycle, places one foot on a pedal, pushes off, and begins pedaling smoothly. Balance improves with motion, and steering is controlled by gently turning the handlebars. Braking is done using hand levers, which activate either rim brakes or disc brakes depending on the bike type. Riders should always wear a **helmet**, follow traffic rules, and remain aware of their surroundings.
