Throttle: Allows you to engage the motor without pedaling (on some models).

1.2. How Electric Bikes Work

E-bikes offer a unique riding experience by combining human power with electric assistance. Here’s how they generally work:

Pedaling: You start pedaling like a regular bicycle.
PAS Activation: The Pedal Assist System (PAS) detects your pedaling and signals the motor to engage.
Motor Assistance: The motor provides a boost to your pedaling, making it easier to climb hills, ride against the wind, or carry heavy loads.
Throttle Option: Some e-bikes have a throttle that allows you to engage the motor without pedaling, providing pure electric power.
Battery Power: The battery provides the energy for the motor, and the controller manages the power output.
Variable Assistance: Most e-bikes offer different levels of assistance, allowing you to customize the amount of motor power you receive.

1.3. Classes of Electric Bikes

Understanding e-bike classifications is crucial for navigating regulations and choosing the right type for your needs:

Class 1: Pedal-assist only, with a motor that stops assisting at 20 mph.
Class 2: Throttle-assisted, with a motor that can propel the bike up to 20 mph without pedaling.
Class 3: Pedal-assist only, with a motor that stops assisting at 28 mph.

Knowing these classifications helps you choose an e-bike that fits your local laws and riding style.
