What’s an electric bike? I remember the first time that I ever got to see an electric bike, commonly known as an e-bike, around 2017. My family owns a bike shop and we always used to just have regular bikes, until we began selling e-bikes. I was really intrigued by them since I’ve never been the most athletic person. I would often struggle with things like going up a hill, going long distances, or even just keeping up with my brother on bike rides.

E-bikes changed everything for me. It’s almost like someone is giving you a push on your bike, while you’re still doing all the work. Suddenly, I’m able to go up hills easily, go on longer rides, and easily be able to keep up with my brother. E-bike made a huge difference to my riding experience and has helped me ride faster and farther than I would ever be capable of on a regular bike.

Maybe you’ve heard people talk about them, and you’re curious. You might even think they’re like motorcycles, but they’re not! E-bikes are an incredible way to get exercise, and they can give you a little boost when you need it to help you go faster and farther on your rides. Let’s find out what makes them so neat.

Defining the Electric Bike: Core Components and Functionality

So, what’s an electric bike? Imagine a regular bicycle but with a secret weapon! That weapon is a motor, a battery, and a controller. These three things work together to help you ride.

• The Motor: This is what gives you the push. It turns the battery’s power into movement. I like to think of it as someone coming up behind you to give you a push as you pedal. It’s the muscle that makes the bike move when you need it to.
  

• The Battery: This stores the power for the motor. It’s like a big energy pack. Most e-bikes use batteries like the ones in your phone or laptop. The bigger the battery, the farther you can go before needing to charge it again. This is called “range,” like how far a car can go on a tank of gas. To charge an e-bike, you will be given a charger that you can plug into the wall. For many e-bikes, you will also receive a key that can allow you to take the battery out of the e-bike.
  

• The Controller: This is like the brain. It takes input from the sensors (like your pedaling speed and force) and the throttle, and then tells the motor how much power to deliver. This makes hills easier and long rides shorter. It’s the part that decides how much help the motor gives you. The controller is located on the handlebar. The simplest e-bikes will allow you to turn on the electric part of the bike, allow you to control the level of assist you receive, and see how much battery is left. Many e-bikes will also have a display located at the center of the handlebar that can tell you things such as the percentage of battery you have left, how much more range you have remaining in the charge, how fast you are going, and how many miles you have put onto your e-bike, and a number display for the level of assist you are using.

When you pedal, or sometimes when you use a throttle (like on a motorcycle), the controller tells the motor to turn on. This makes it easier to go up hills or ride longer distances. Think of it as a helping hand!

The Engine of Assistance: Motors Explained

There are two main types of motors you’ll find on e-bikes.

• Hub Motors: These are in the center of the wheel, like a tiny engine. They push the wheel directly. They’re simple and often found on cheaper e-bikes. They’re good for flat roads and small hills. Because they are in the wheel, it simplifies the design of the bike and makes repairs easier.
  
  

• Mid-Drive Motors: These types of motors, often found in higher-quality e-bikes are located in the middle of the bike, near the pedals. This placement allows them to push the pedals, allowing for a more natural feeling when pedal assist is used. They’re better for big hills and rough roads. Because they push the pedals, they use the bike gears, making them more efficient. As Gazelle, a Dutch e-bike company discusses in this article, mid-drive motors “power the front chainring along with your own pedal power to give a smooth and consistent ride feeling.

You might hear people talk about “torque” and “wattage.” Torque is how much “push” the motor gives, and wattage is how much power it uses. More of both means you can go faster and up steeper hills. Think of torque like how quickly you can get up to speed, and wattage as how much power you have to keep going.

Powering the Ride: Batteries and Range

The battery is what makes the motor work. Most electric bikes use batteries like the ones in your phone or laptop. The size of the battery tells you how far you can go before needing to charge it again. This is called “range.”

There are various factors that can contribute to the amount of range you can get in a single charge such as the capacity of the battery, torque, wattage, weather conditions, terrains, the level of pedal assist used, and the e-bike type. If you take care of your battery, it will last longer. Don’t leave it in very hot or very cold places. In this article, it is ideal to put the battery in an area that is over 50 degrees, otherwise, the battery performance could be affected. It is also important to not let the battery fully drain often, as this can reduce its lifespan.

Controlling the Ride: Displays, Controllers, and Sensors

You can control your e-bike with a display and controller. The display shows you how fast you’re going, how much battery you have left, and other important stuff.

• Pedal Assist: This means the motor helps you when you pedal. Sensors feel when you’re pedaling and make the motor help. As you pedal like normal, you are able to feel the assist kick in and it will allow you to go faster without changing how fast you pedal. The bike company, Momentum describes pedal assist as being assisted by a small motor that engages to give you the boost you need. E-bikes typically have different levels of pedal assist, usually with at least 3 power levels. You are easily able to adjust the level of assist and even have the option to turn off the assist to ride like a regular bike. Although higher pedal assist makes it much easier to pedal, it can drain the battery easily and reduce the amount of range you get in that charge. 
  
• Throttle: This is like a gas pedal on a motorcycle. Really Good Bikes describes them as a simple control that is usually located on the handlebar, that lets you directly engage the electric motor. You twist or press down the button, and the motor pushes you. Some throttles kick in more smoothly than others, but you are not required to pedal. Throttles require more power than pedal assist and will immensely reduce the amount of range you can use on a single charge. These are found in class 2 e-bikes and occasionally class 3 e-bikes.
  
• Sensors: These tell the motor how hard you’re pedaling. They make the ride smooth. Some sensors measure how fast you pedal, and others measure how hard you pedal. Harder pedaling sensors give a more natural feel. As stated in this article Engwe, different types of sensors include pedal assist sensors, torque sensors, brake sensors, speed sensors, and cadence sensors.

Understanding Electric Bike Classes: Navigating the Regulations

E-bikes are divided into classes. To help riders and regulators understand the varying capabilities of e-bikes, the industry has largely adopted a three-class system, as shown in PeopleForBikes’ Electric Bicycle Initiative Overview, which categorizes e-bikes based on motor assist and speed.

• Class 1: Pedal assist only, up to 20 mph. These are often allowed on bike paths. This class is very common on trails, and bike paths.
  
• Class 2: Pedal assist and throttle, up to 20 mph. These might have some trail restrictions. Some trails disallow throttles, so this class is sometimes banned.
  
• Class 3: Most are pedal-assist only, up to 28 mph. Some Class 3 e-bikes have a throttle, but the throttle will only go up to 20 mph.

These classes help decide where you can ride your e-bike. Always check your local rules.

Matching the Electric Bike to Your Needs: Types and Applications

E-bikes come in all shapes and sizes!

• Commuter E-bikes: For riding to work or school. These are designed for comfort and efficiency on paved roads. These types of bikes will have you sitting in a more upright position H3
  
• Cargo E-bikes: For carrying groceries or kids. These have a longer wheelbase and sturdy frame to handle heavy loads.
  
• Mountain E-bikes: For riding on trails. These feature robust suspension and powerful motors for off-road adventures.
  
• Folding E-bikes: For easy storage and travel. These are compact and portable, ideal for urban commuters.

The motor, battery, and controller are adjusted for each type of bike

Addressing Common Questions and Misconceptions

• “Electric bikes are cheating.” As a salesperson at a bike shop, I have customers saying this to me frequently when they notice our e-bike section that’s close to our checkout counter and it’s simply not true. While throttles do not require pedaling, that is not the main purpose of an e-bike. Most e-bikes do not have a throttle and are solely used for pedal assist. You are still pedaling and doing all of the work. They can provide as little or as much assist as you need and can help you ride further and easier. You still get exercise, just like a regular bike! E-bikes make cycling accessible to more people, including those with physical limitations.
  
• “Electric bikes are hard to fix.” Basic maintenance is easy, like on a regular bike. However, motor and battery repairs may require specialized knowledge. Due to the complexity of electrical components, it is recommended to purchase an e-bike through a local bike shop rather than online. For our bike shop, we are able to provide basic maintenance that can also be done on a regular bike, but we cannot service the electrical components of an e-bike that was not purchased from us. We simply don’t have the necessary tools and knowledge on the particular brands to be able to properly service them and can’t risk the liability.
  
• “Electric bikes are too expensive.”  E-bikes have a wide range in prices, starting anywhere from $600 for the most entry-level e-bike to $3000+. Revi Bikes provides a guide to understanding the price range of different e-bikes. They are more expensive than a regular bike, but they can be used for both exercise and transportation. With many businesses shutting down during the COVID-19 pandemic, bike shops were able to stay open due to being deemed essential for transportation reasons. They can save you money on gas and parking when used for transportation. Consider the long-term cost savings compared to car ownership and the capabilities you get in comparison to a regular bike.

The Evolution of the Electric Bike: Future Trends

E-bikes are getting smarter! New batteries last longer, and some e-bikes have GPS and anti-theft systems. E-bikes are also helping make cities cleaner and greener. A study by the University of Oxford found that e-biking can replace car journeys, reducing CO2 emissions, and providing significant physical and mental health benefits, similar to traditional cycling. Future trends include more powerful and efficient motors, longer-lasting batteries, and seamless integration with smart city infrastructure.

E-bikes are a fun and easy way to get around. They’re not just for super athletes. They’re for anyone who wants a little help on their ride. I hope you now understand what makes them so special. Next time when you see someone zooming by, you’ll know they’re enjoying the power of an e-bike!
