A bike wheel works by rotating, allowing the bike to move forward. The wheel's circular shape and smooth surface reduce friction with the ground, making it easier to propel the bike.
Here's how it works in detail:
1. The Axle:
- The wheel is attached to the bike frame through a metal rod called the axle.
- The axle allows the wheel to spin freely.
2. The Spokes:
- Spokes are thin metal wires connecting the rim to the hub.
- They distribute the weight of the rider and bike evenly across the rim, keeping the wheel strong and stable.
3. The Rim:
- The rim is the outer edge of the wheel.
- It provides a solid surface for the tire to attach to.
4. The Tire:
- The tire is a rubber tube that fits around the rim.
- It provides traction and absorbs shocks from the road.
5. Rotation and Movement:
- When you pedal, the chain transfers power to the rear wheel.
- This rotation of the rear wheel pushes against the ground, creating friction.
- The friction propels the bike forward.
6. Steering:
- The front wheel is connected to the handlebars.
- By turning the handlebars, you change the direction of the front wheel, which allows you to steer the bike.
In summary, a bike wheel works by rotating, transferring power from the pedals to the ground, and providing stability and steering.
