  • Central or mid-drive motor : Located near the pedals, this motor influences how the electric bike works by providing a more centered weight balance and better traction. This arrangement is especially beneficial on uneven terrain, improving how the electric bike performs in more demanding conditions.

Engine Operating Principles

When the rider pedals, the motor activates, providing additional assistance. This assistance is regulated to complement the cyclist's effort, which is key to how the electric bike works, allowing for a more efficient and less tiring ride.

The level of assistance provided varies depending on the e-bike model and the rider's preferences. This setting is central to how the electric bike works, as it allows the rider to customize their riding experience based on their needs and road conditions.

The Battery: Heart of the Electric Bicycle

The battery is an essential component in how the electric bike works, acting as the energy source that powers the motor. Its capacity and efficiency are determining factors in how the electric bike works, directly impacting its autonomy and performance.

Types of Batteries

Within how the electric bicycle works, there are several types of batteries, each one with specific characteristics:

  • Lithium Ion (Li-ion) Batteries: They are the most common in how electric bikes work due to their weight-power ratio and energy efficiency. These batteries also have a long cycle life, which is crucial in how the electric bike performs in the long term.
  • Nickel-Metal Hydride (NiMH) Batteries: Less common in how electric bicycles work, these batteries are known for their durability and recyclability.

The type of battery chosen significantly affects how the electric bike works, including aspects such as weight, range and charging time.

Charge management is a key aspect of how the electric bike works. It is important to charge the battery regularly and avoid leaving it in a low state of charge for long periods. Additionally, storage in a dry, temperature-controlled location helps preserve battery health.

Control and Assistance Systems

The Pedaling Assist System (PAS) is fundamental to how the electric bicycle works. This system detects the rider's pedaling effort and activates the motor to provide an appropriate level of assistance. The efficiency of how the electric bike works with PAS depends on the sensitivity and precision of this system to adjust to the needs of the cyclist.

Controllers and Assistance Modes

The controller is the brain that regulates how the electric bike works. Manages the power sent to the engine based on rider input and riding conditions. The different assistance modes, which the rider can select, alter how the electric bike works, allowing the user to choose between more physical effort or greater motor assistance.

This is especially important in situations such as riding on slopes or accelerating from a standstill, where understanding how the electric bike works is essential for a safe and enjoyable riding experience.

Speed ​​and Torque Sensors

Speed ​​and torque sensors are vital components. These sensors provide real-time information to the controller about the speed of the bicycle and the force exerted on the pedals. This information is essential, ensuring that motor assistance is adequate and proportional to the rider's effort.

Speed ​​and Performance

Speed ​​and performance determine how effectively the electric bike performs in different environments and conditions, being essential to understanding how the electric bike performs in terms of capabilities and limitations.

Maximum Speed ​​and Regulations

Regulations on the maximum speed that an electric bike can reach vary depending on local legislation, but are generally designed to ensure the safety of both the cyclist and other road users. These regulations directly influence how the electric bike works, defining the limits within which the motor can assist the rider.
