How do electric bikes work?

From the outside, ebikes seem to work like regular bicycles. They have similar parts with very slight differences. However, these differences are the things that make electric bikes stand out. Their electric component helps in improving the biker’s effort, not replacing it. These bikes make it easy to scale obstacles like hills and travel for long distances without getting tired.

Choosing the right electric bike

It is important to only make use of electric bike components that are top-notch. These include:

The Motor

Ebike motors are made with different power ratings, ranging from 200W to 1000W. However, the regulated power limit is 500W, though it varies in different states. Electric bikes with higher power ratings can easily pull more weight with less strain, but this impacts their battery life greatly. Therefore, although a 500W motor is more powerful than the 250W one, it drains the battery much faster. The 750W electric cargo bike KBO Ranger can go up to 24 mile per hour.

Another important factor is how the motor is designed and where it is located. Hub motors are one of the commonest types of electric bike motors and are usually installed into the rear or front wheel. The motor propels the ebike as the wheels turn. However, this system is not as efficient because it is not directly connected to the gears.

The Battery

The battery of an ebike is another crucial part of how it works. The commonest types of batteries are the following:

  • Sealed Lead Acid (SLA)

These used to be the best batteries for electric scooters and bikes in times past. But while only scooters have seemingly retained the SLA batteries, ebikes now make use of the latest battery technologies. These batteries are more efficient and keep your bike as light as possible.

  • Lithium-ion Batteries

Lithium-ion batteries are currently the best batteries for electric bikes, with a span of almost 2-3 times that of SLA batteries. They are very light and do not necessarily require frequent maintenance. The KBO Breeze Step-thru commuter e-bike from KBO electric bike has a 48V 16Ah Samsung Li-ion battery, which can go up to 55 miles on a single charge.

The Controller

There are different types of controllers for electronic bikes. These tools help in operating the bike’s electric assistance and are essential to their effective functioning. It is usually located in the handlebar for ease of use. The two main types of controllers are pedal-activated and throttle-based controllers.

  • Pedal-activated Controllers

The pedal-activated systems work by offering the biker electric assistance as soon as the pedals are pressed. They are not activated by a throttle. Instead, pedaling is enough to do the trick. The pedal-activated systems have their controllers mounted on the handlebar, so you can adjust the level of assistance you use while riding. The assistance level ranges from no assistance to a great deal of assistance, so opt for that which suits you best.

  • Throttle-based Controllers

These controllers work by a simple throttle mechanism which can either be a twist-grip or thumb-press type. However, with a throttle, you are allowed to pull back and press the throttle for electric assistance. There are even electric bicycles that do not require having the throttle activated, so you can ride without pedaling.

Therefore, it is important to understand that electric bikes are very easy to use and maintain. Despite all their amazing benefits over regular bikes, they only require a little maintenance because of the battery and motor.

How Are Electric bikes Operated?

Electric bikes are really easy to operate. So as a rider, there are three modes of operation you can access:

  • Pedal Only

Every biker has the option of pedaling their ebike as they do regular bikes. In this type, there is no extra assistance from the motor, so it works exactly like a regular bike. However, this is only one of the variety of pedaling options available for e-bikes.

  • Pedal-Assist

For pedal assists, it is a smooth blend of human and electric power. Therefore, as soon as the mode is turned on from the handlebars, the motors provide electric power as the pedals are pushed. Also, the pedal-assist gives you the freedom to switch gears on different terrains and increase how much help the ebike provides.

The pedal-assist mode gives you an amazing feeling because it makes riding effortless, helps you scale obstacles with ease, and moves with more speed while enjoying the scenery. This mode provides three levels of assistance, which are: low(30%), medium(60%), and high(100%). The percentages show how much additional power is provided by the motor while pedaling. With a simple push of a button, you can change your biking story forever.

  • Electric-Only

The electric-only mode completely eases you of all pedaling stress, so the bike is in full control. If you want to take a break while riding, this is perfect for you. To activate this, you simply have to twist the throttle on the handlebar, and almost immediately, the motor kicks in and propels the bike forward. The electric-only option is only available for as long as you keep the throttle twisted. As soon as you release it, you resume full control of your bike’s functions. Endeavor to not exceed a speed limit of 20 miles per hour while riding.

How do Ebikes Work?

The electronic bike has sensors that measure the torque input, cadence, and speed. Therefore, when a biker turns on the pedal-assistance, it is detected by the electric bike’s sensors, which then prompt the release of power from the battery to energize the motor’s electromagnets.

In the ebike’s made these days, the throttle no longer accentuates the motor’s input. Instead, this is done by the motor itself, providing you with a smooth and convenient ride. The e-bike’s mid-drive motor is made up of both permanent- and electromagnets, which are energized by the power supplied from the battery.


The workings of an ebike are all geared towards improving your biking experience and making it less stressful. This is actualized by the sensors, motors, pedal assists, and all the other parts that contribute to the uniqueness of ebikes. Once a biker pushes the button for help, all involved parts synergistically combine to reduce the effort exerted by the biker to move the ebike.

Having a good understanding of how ebikes work is important for any biker. This boosts your knowledge and gives you insight into making small-scale repairs that do not require the expertise of a technician. Choose an electric bike with amazing pedal-assist functions and enjoy a life of ease.
