What is an electric bike or e-bike?

An electric bike is also known as e-bike, electric bike is type of bicycle in which the electric hub motor or electric motor with belt drive or chain drive system used to drive the wheels. There are different types of electric bike depending on type of drive system and the purpose.

Electric bikes are usually power by rechargeable li-ion battery pack. Which are mounted on e-bikes with integral on frame or mounted externally.

Depending on the drive type e-bikes are classified in different types such as pedal assist e-bike and throttle control motor drive e-bikes. In pedal assist e-bike they use traditional pedals and electric motor both can be used as required. In motor drive only motor is used to drive wheels.

Electric bikes offer an eco-friendly and efficient alternative to traditional bicycles, providing a viable option for commuting, recreational cycling, and addressing mobility challenges. Their popularity has been on the rise as technology advances, making them more affordable, lighter, and capable of catering to a wide range of users and preferences.

Types of e-bikes

Pedal assistance e-bike

In pedal assistance e-bikes operate on a pedal-assist system, where the electric motor provides assistance to rider as rider pedals. This helps to efforts required pedal and makes easy to pedal for rider especially clamping hill and for longer distance travel.

Throttle control

In throttle control electric bikes motor power is allowing riders to use the electric motor without pedaling. This feature is common in electric scooters and provides relaxation to rider. Throttle control electric bike allows the rider to control speed.

How electric bikes works?

Electric motor

Electric motor is most important part of all e-bikes which power the wheels of electric bikes. In electric bikes there are two different types motors are used that is hub motor and mid drive motor.

Hub motor is integral with wheel of electric bike and mid drive motor is placed within the frame of e-bike. Each placement has its advantages, affecting factors like weight distribution and handling.

Rechargeable Battery Pack

This is important part of e-bike which power the electric motor of e-bike. determining the range of an electric bike. These batteries can be charge in home electric supply.

Lithium-ion batteries are commonly used for their energy density, lightweight nature, and durability. Charging times vary, but it typically takes a few hours to recharge an e-bike battery fully.

Electronic Control system

E-bike are on board with electric control unit that manages the interaction between the motor and the rider. This system includes a user interface such as display or control panel which allows the rider adjust setting and monitor battery condition.

Pedal assistance e-bike

E-bikes operate on a pedal-assist system. As the rider pedals, sensors detect the motion and force applied to the pedals. The electric motor then provides assistance in proportion to the rider’s effort, making pedaling easier.

Throttle control

E-bikes come with a throttle control, allowing riders to engage the electric motor without pedaling. This feature is more common in certain types of e-bikes, such as electric scooters.

Regenerative braking systems

In e-bikes electric motor is acts as generator when start climbing down from high to low side or deaccelerate from hill. This electric energy is then restored in batteries of electric vehicle.


Electric bike can be charged at household electric supply whenever battery needs to be charge. Charging times vary but typically take a few hours to reach a full charge.

Speed and drive range

An electric bike come with different speed limits, often restricted to comply with local regulations. The range of an electric bike depends on factors like the battery capacity, motor efficiency, and terrain. Many e-bikes can cover distances ranging from 30 to 160 km (20-100 miles) on a single charge.

The regulations regarding electric bikes vary globally and even within regions. Some places classify e-bikes as regular bicycles, while others may impose restrictions on speed, power, or where they can be ridden.           

Advantages of e-bike

Electric bikes offer advantages as follows

  • e-bike provides electric assistance pedaling which makes ride comfortable while climbing hills and long distance.
  • In electric bike motor allows the rider cover longer distance with comfort and without fatigued. expanding commuting possibilities and reducing reliance on traditional transportation.
  • Electric bikes are eco-friendly and operates zero emission of greenhouse gases. Contributing to cleaner environment reducing air pollution.
  • E-bikes are generally more cost-effective than cars or motorcycles in terms of purchase price, maintenance, and fuel costs. They can offer significant savings over time, especially for daily commuting.
  • Electric bikes can be used for various purposes, including commuting, recreational cycling, fitness, and even cargo transportation. Some models are designed for specific activities like mountain biking or urban commuting.
  • E-bikes can navigate through traffic more easily than cars, reducing commute times. Additionally, they require less parking space, helping alleviate congestion and parking-related issues in urban areas.
  • While e-bikes provide electric assistance, riders still engage in physical activity by pedalling. This helps improve cardiovascular health, muscle tone, and overall fitness, promoting a more active lifestyle.
  • E-bikes make cycling accessible to a broader demographic, including older individuals or those with physical limitations. The electric assistance enables people to enjoy the benefits of cycling without excessive physical exertion.
  • Electric bikes are quieter than traditional vehicles, contributing to a quieter and more peaceful urban environment. This can be particularly beneficial in densely populated areas.
  • E-bikes can promote community engagement as people are more likely to cycle when it is made easier. Group rides, cycling events, and a sense of shared mobility contribute to a more connected community.
  • E-bikes can help alleviate traffic congestion in urban areas, as they take up less space on the road and can move through traffic more efficiently than larger vehicles.
  • Some regions offer incentives, subsidies, or tax benefits for the purchase of electric bikes, making them more financially attractive and promoting sustainable transportation alternatives.

Disadvantages of e-bike

Electric bikes have some disadvantages as follows

  • E-bikes are more expensive as compared to the traditional bicycles because of addition of the electric motor and battery.
  • E-bikes have a decent range on a single charge, but they are limited by battery capacity. Long-distance commuters may need to plan their routes carefully and consider charging options along the way.
  • The availability of charging infrastructure, especially in certain regions, may be limited. This can be a concern for riders who rely heavily on their e-bikes for commuting or longer trips.
  • E-bikes tend to be heavier than traditional bicycles due to the additional components like the motor and battery. This extra weight can impact handling and make it more challenging to transport the bike, especially if manual pedaling is required.
  • Maintenance of e-bikes required most cost as they have electric component like electric motor and electric battery.
  • The integration of electronic components makes e-bikes more complex than standard bicycles. This complexity can lead to increased chances of technical malfunctions, requiring specialized knowledge for repairs.
  • he production and disposal of lithium-ion batteries, commonly used in e-bikes, have environmental implications. Proper recycling practices are crucial to mitigate these impacts.
