Exploring the Basics of Electric Bikes: What They Are and How They Operate

With the advancement of technology, electric bikes (ebikes) are gradually becoming a part of modern transportation. This article will introduce the basics of electric bikes, including their definition and how they function.

What Is an Electric Bike?

When the term electric bike is mentioned, some may envision a scooter or electric motorcycle. However, electric bikes actually look quite different from these. Picture a regular bicycle, then seamlessly integrate various electronic components like a motor, a battery, and a controller into its design. These components form the foundation of all electric bikes available in the market.

How Electric Bikes Work

In comparison to regular bikes, electric bikes pedal and handle similarly. By and large, they use the same parts as traditional bicycles. The electric components are designed to enhance human power, not replace it entirely. This means that electric bikes can make obstacles like hills and headwinds more manageable, allowing you to travel further without feeling as fatigued.

In an electric bike, the motor, battery, drivetrain, and charging system are crucial components. The motor comes in various power ratings, and the choice of battery significantly affects the bike's weight, style, and range. Additionally, electric bikes are equipped with a controller that allows you to select different assistance modes, such as pedal-assist, electric-assist, or pure electric.

Choosing the Right Electric Bike

When selecting an electric bike, several key factors should be considered:

  • Motor: Electric bike motors have a wide range of power ratings, with legal limits set by regulations. The design and location of the motor also play a vital role. Hub motors are common, but mid-drive motors, integrated with the crank and gears, offer advantages in performance and hill climbing.

  • Battery: The choice of battery is crucial as it directly impacts the bike's weight, style, and range. Lithium batteries are the latest technology, offering a longer lifespan and being lightweight compared to sealed lead-acid batteries.

  • Controller: The controller allows you to operate the electric assistance on your bike. There are pedal-activated and throttle-based controllers, each with its own operation style.

Operating an Electric Bike

Electric bicycles are designed to be easy to operate, offering three modes of operation:

  • Pedal Only: Pedal an electric bike just like a regular one, with no extra resistance created by the motor.

  • Pedal-Assist: Combine human and electric power by pedaling, with the motor providing gentle assistance. Different levels of assistance can be selected, making cycling effortless.

  • Electric-Only: Use the motor exclusively by twisting the throttle, allowing you to ride without pedaling. Federal regulations limit the top speed in electric-only mode to 20 miles per hour.

Licensing and Regulations

Electric bikes are considered in the same class as regular bicycles under federal law, with specific conditions regarding speed and motor power. They do not require special registration, license, or insurance, enjoying the same privileges as regular bicycles. However, state-specific regulations may vary, and it's advisable to check local laws.


Electric bikes are becoming a part of modern commuting, offering riders more choices and convenience through electric assistance. Understanding the basics of electric bikes can help you make informed decisions when purchasing and using them, meeting your individual needs and preferences. Whether you seek an easier commute in the city or an environmentally friendly transportation option, electric bikes could be an ideal choice.
