How does an e-bike work?
Electric motor
The heart of an e-bike is its electric motor, which is responsible for providing power and propulsion. The motor can be either a hub motor or a mid-drive motor. Hub motors are located in the center of either the front or rear wheel, and they provide direct power to that wheel. Mid-drive motors, on the other hand, are located near the bike’s bottom bracket and provide power through the bicycle’s gears. The motor is usually powered by the e-bike’s battery and is controlled by the controller.
Battery
The battery is a crucial component of an e-bike, as it stores the energy needed to power the electric motor. E-bike batteries are typically lithium-ion or lithium-polymer, as they offer high energy density and long life cycles. The battery is usually removable and can be charged either on or off the bike. The capacity of the battery, measured in watt-hours (Wh), determines the range of the e-bike. Higher capacity batteries allow for longer rides without needing a recharge.
Controller
The controller is the brain of the e-bike, managing the flow of power from the battery to the motor. It also controls additional features such as throttle and pedal assist. The controller monitors various parameters such as speed, pedal cadence, and torque, and adjusts the motor’s assistance accordingly. Some controllers also come with a display that shows information such as battery level, current speed, and distance traveled.
Throttle and pedal assist
E-bikes can be equipped with a throttle or a pedal assist system, or a combination of both. A throttle allows the rider to control the motor’s power output directly, similar to a motorcycle or scooter. With a throttle, you can simply twist or press a lever to engage the motor and start moving without pedaling. On the other hand, a pedal assist system senses when the rider is pedaling and provides assistance based on the level selected. The higher the level, the more assistance the motor will provide.
Regenerative braking
Some e-bikes also feature regenerative braking, which allows the battery to recharge while slowing down or descending hills. Regenerative braking works by reversing the flow of electricity from the motor and using it to charge the battery. While regenerative braking does not provide the same level of braking power as traditional brakes, it can help extend the range of the e-bike and improve overall efficiency.
