How does sliding friction help you ride a bike?

Explanation

### Step-by-Step Solution:

1. **Understanding Friction Types**:
- Friction is a force that opposes motion between two surfaces in contact. There are different types of friction, including static friction, sliding (kinetic) friction, and rolling friction.

2. **Role of Rolling Friction in Biking**:
- When you ride a bike, the tires roll on the ground. This rolling motion is primarily influenced by rolling friction, which allows the bike to move forward smoothly.
