## 1. Understanding Electric Bicycle Systems {#understanding-systems}

Before diving into individual components, it's important to understand how electric bicycle parts work together as a system.

### The E-Bike Power System

An electric bicycle is essentially a traditional bicycle with an electric drive system added. This system consists of:

```

[Battery] ?[Controller] ?[Motor] ?[Wheels]

? ? ?[Charger] [Sensors] [Display]

```

**How It Works**:

1. **Battery** stores electrical energy

2. **Controller** manages power flow based on rider input

3. **Motor** converts electrical energy to mechanical power

4. **Sensors** detect pedaling, speed, and torque

5. **Display** shows system status to the rider

### Key System Considerations

**Voltage Compatibility**:

All components must be rated for the same voltage (e.g., 48V, 52V). Mixing incompatible voltages can damage components or create safety hazards.

**Current Ratings**:

The controller's current rating (Amps) determines how much power can flow to the motor. Higher current = more power, but also more heat and wear.

**Connector Types**:

Different manufacturers use different connectors. Ensure compatibility or be prepared to adapt connections.

---

## 2. Core Components Overview {#core-components}
