Bicycles have long been a popular mode of transportation and recreation, providing a fun and efficient way to get around while promoting health and fitness. In recent years, the introduction of electric bikes or e-bikes, has added a new level of convenience and accessibility to cycling.
E-bikes use an electric motor and battery to assist the rider, making it easier to pedal and allowing for greater speed and range. E-bikes come in various types, including electric city bikes, mountain bikes and cargo bikes and can be an excellent option for commuting, exercise and leisure activities.
How Do E-Bikes Work?
E-bikes use an electric motor and battery to assist the rider while pedaling. The motor is usually located in the hub of the wheel or in the middle of the bike frame and is powered by a rechargeable battery that can be removed or integrated into the frame.
When the rider pedals, sensors detect the movement and signal the motor to provide assistance, which can be adjusted using a control panel on the handlebars. The level of assistance varies depending on the model and can range from minimal to full motor power. E-bikes also have a throttle that can be used to engage the motor without pedaling, similar to a scooter or motorcycle.
The motor and battery can add weight to the bike, but technological advances have made e-bikes more lightweight and efficient than ever before. For example, foldable electric bikes are light and agile, allowing commuters to pack and store their bike when not in use.

Understanding e-bike jargon can help you make the right purchase when searching for your ideal bicycle. Common terms to know refer to an e-bike’s parts, capabilities and features:
- Watt-hour. A watt-hour is a measurement of battery capacity which indicates how much energy the battery of the e-bike can store. You will typically see it expressed as 300Wh or above.
- Torque. Torque refers to the twisting force produced by the motor that helps with acceleration and climbing hills. Torque is critical when choosing an electric mountain bike, with most models ranging between 50Nm and 90Nm.
- Power. The amount of energy produced by the motor, measured in watts.
- Range. The distance the e-bike can travel on a single charge. The distance will vary depending on battery capacity and the terrain you are traveling; however, a typical charge lasts between 20 and 40 miles.
- Charging time. How long it takes the battery to fully charge from empty. It normally takes anywhere from three to six hours, depending on the size of the battery and your charging cable.
- Hub-driven. Hub-driven e-bikes have a motor positioned next to one of the wheels, most commonly the back wheel. This motor works by spinning the wheel when you want assistance.
- Mid-drive. Mid-drive motors are placed in the middle of the bike, which helps with the rider’s balance and makes the bike assistance feel more natural. Mid-drive motors assist you as you pedal rather than adding more power like a hub-driven motor.
- Refurbished or certified, pre-owned. Refurbished electric bikes refer to pre-owned e-bikes that have been inspected and fixed to meet like-new standards. These bikes allow riders to buy brand-name electric bikes at up to 60% of the cost of buying new.
Pedal-Assist vs. Throttle-Powered Electric Bikes
When it comes to e-bikes, there are two main types: pedal-assist and throttle-powered. Pedal-assist e-bikes assist the rider only when they are pedaling. The level of assistance can be adjusted using a control panel and can range from minimal to full motor power. Pedal-assist e-bikes are more similar to traditional bikes in terms of the effort required to ride and can be a good option for those who want a more natural riding experience.
Throttle-powered e-bikes allow the rider to engage the motor without pedaling, similar to a scooter or motorcycle. Throttle-powered e-bikes are easier to ride and require less physical effort but can be less efficient and have a shorter range than pedal-assist e-bikes.
Laws and regulations surrounding e-bikes vary depending on the type, with some areas limiting or prohibiting throttle-powered e-bikes on certain roads or paths.
Classifications of E-Bikes
The most common way to classify e-bikes is with the 3-class system recognized by 26 different states.
- Class 1: Pedal assist only with a maximum speed of 20 mph
- Class 2: Has a maximum speed of 20 mph, but it comes with throttle assist to propel the bike without pedaling
- Class 3: Pedal-assist only with a maximum speed of 28 mph
In general, e-bikes are allowed on roads and bike lanes, as well as some bike paths and trails. However, some areas may restrict e-bikes, particularly throttle-powered e-bikes or those with higher maximum speeds.
It’s essential to research the regulations and laws in your area before riding your e-bike, as violations can result in fines or other penalties. Additionally, some areas may have specific rules for e-bike riders, such as requiring helmets or limiting the hours of operation.
Types of E-Bikes
E-bikes come in various styles, each designed to meet the needs and preferences of different riders. Whether you’re looking for a bike for commuting, off-road adventures or leisurely rides around town, there’s an e-bike that’s perfect for you.
● Electric City Bike. An electric city bike is designed for commuting every day or getting around a city without the use of public transportation or a car. The frame is typically upright, with a relaxed seat tube angle, swept-back handlebars and a low step-through height.
● Foldable Electric Bike. Foldable electric bikes prioritize being compact and easy to store. Because of this, they are usually smaller, more lightweight, less powerful and have a shorter range.
● Electric Mountain Bike. Electric mountain bikes are meant for off-roading and handling rugged terrain. Their frames are more durable than other electric bikes but often much heavier and optimized for stability and maneuverability on steep inclines and uneven surfaces.
● Electric Road Bike. Electric road bikes are designed to be used on paved roads. The frame is typically lightweight and features a steep seat tube angle, a low front end and a longer top tube to create an aerodynamic riding position. The tight frame angles enhance handling and responsiveness at high speeds.
● Electric Cargo Bike. Electric cargo bikes are meant to carry large amounts of goods and passengers, making them ideal for those needing to transport items or grocery shopping. They have a longer wheelbase and racks attached to the back wheel.
Gears and Assist Levels
E-bikes typically have multiple gears and assist levels to help the rider adjust the level of assistance provided by the motor. Gears allow the rider to adjust the resistance and effort required when pedaling and can be helpful for going up hills or riding in different terrain.
Assist levels allow the rider to adjust the amount of assistance provided by the motor. Most e-bikes have multiple assist levels, ranging from eco to turbo boost. The level of assistance can be adjusted using a control panel on the handlebars and can be useful for conserving battery life or getting a more challenging workout.
Some e-bikes also have an automatic assist mode, which adjusts the level of assistance based on the rider’s pedaling speed and effort.
Find the Right Bike for a Better Ride
E-bikes have revolutionized the world of cycling, offering a convenient and accessible way to get around while reducing the effort required to pedal. From city bikes to mountain bikes, there is a refurbished electric bike for every type of rider and activity.
Understanding the different types of e-bikes, regulations and laws, battery life and other factors can help you choose the right e-bike for your needs and ensure a safe and enjoyable riding experience.
