What Is an Ebike? Learn How Electric Bikes Work

KnowledgeMar 25, 2025

An electric bike—often called an e-bike—is a bicycle that comes with a built-in motor and battery. That motor gives you a boost while pedaling, making it easier to ride up hills, cruise through headwinds, or simply go farther with less effort. It’s like cycling, but smoother and less tiring.

So, what is an ebike really? In short, it's a modern take on traditional biking. These bikes use a combination of electric bike motors, pedal sensors, and batteries to give riders adjustable levels of assistance. Whether you're commuting to work or just enjoying a weekend ride, e-bikes make cycling more accessible for all kinds of riders.

This guide breaks down what are electric bikes, how ebike motors work, and the different types available today. You'll also find tips on how to choose the right one and a look at standout brands like Leoguar—known for building practical, affordable options that make electric cycling easy to enjoy.

What is an Ebike? Understanding the Concept of Electric Bicycles

At its simplest, an ebike—short for electric bike—is a bicycle equipped with a motor and battery that helps you pedal more easily. Think of it as a regular bike, but with built-in support when you need it, like going uphill or riding into the wind.

Most electric bikes offer two main ways for the motor to assist you. The first is pedal assist (PAS), where the motor kicks in only when you’re pedaling—and the harder you pedal, the more support you get. The second is throttle mode, which lets the motor do the work at the push of a button, no pedaling required. Many modern e-bikes combine both systems to give riders more flexibility.

Design-wise, today’s electric bikes are sleek and integrated. The ebike motor and battery are often built right into the frame, making them look and ride more like a traditional bicycle than those with add-on kits. You still get full manual control too—so you can choose to ride with power, without power, or somewhere in between.

In the U.S., e-bikes are commonly divided into Class 1, 2, and 3 based on their speed and assist features. These classifications also affect where you’re allowed to ride, so it’s worth checking local rules before heading out.

No matter the class or style, what makes an ebike special is its versatility—it gives you the freedom to ride the way you want, with just the right amount of help.

Core Components That Make Up an Ebike

To understand how an ebike works, it helps to get familiar with its main components. Each part plays a key role in delivering a smooth, powered ride—without losing the feel of a traditional bike.

1. Motor: The Power Behind the Ride
The electric bike motor is what sets an e-bike apart. You’ll typically find either a hub motor, located in the front or rear wheel, or a mid-drive motor, mounted near the pedals. Hub motors are simple and affordable—great for casual riders. Mid-drive motors, on the other hand, offer better balance and use the bike’s gears for improved efficiency and climbing power. Most ebike motors range from 250 to 750 watts, affecting how much torque and speed they can deliver.

2. Battery: Storing the Energy
Most e-bikes run on lithium-ion batteries, known for being lightweight and long-lasting. The battery’s capacity—measured in amp-hours (Ah) or watt-hours (Wh)—determines how far you can ride on a single charge. A higher-capacity ebike battery generally means a longer range, especially when paired with pedal assist.

3. Controller and Display: The Brain of the System
The controller manages power flow between the battery and motor. It responds to your input—whether you're pedaling or using the throttle—and displays key ride data like speed, range, and power level. It’s the system that makes your electric bike engine feel intuitive and responsive.

4. Frame and Mechanics: Built to Handle Power
Electric bikes are often built tougher than regular bikes. Frames are reinforced to handle extra weight, and you’ll often see upgraded components like hydraulic disc brakes, sturdier drivetrains, and stronger wheels for better safety and performance.

5. Sensors: Smarter Motor Engagement
Modern e-bikes come with cadence sensors, which activate the motor when you pedal, or torque sensors, which adjust assistance based on how hard you pedal. These sensors make the ride feel more natural and controlled—especially useful for hills or stop-and-go traffic.

Leoguar focus on using reliable, performance-tested components to ensure every ride feels smooth, safe, and satisfying—whether you're commuting, exploring, or doing a bit of both.

Types of Ebikes and How They Differ

Not all ebikes are the same. From how fast they go to where you can ride them, there are a few key ways to understand the different types of electric bikes—and how to choose the one that fits your lifestyle.

1. E-Bike Classes: Based on Speed and Assist Features
In the U.S., electric bikes are divided into three main classes:

Class 1: Pedal-assist only, with a top speed of 20 mph. Great for city riding and allowed on most bike paths.
Class 2: Includes both pedal assist and throttle, also capped at 20 mph. A good choice for casual riders who want flexibility.
Class 3: Pedal-assist only, but with speeds up to 28 mph. Ideal for commuters, though access to bike paths may vary by region.

These class 1, 2, and 3 ebikes help define what you can ride—and where.

Class	Max Speed	Throttle	Pedal Assist	Legal on Bike Paths
1	20 mph	❌	✅	✅
2	20 mph	✅	✅	✅
