An electric bike, also known as an e-bike, is a bicycle that is equipped with an electric motor and battery. The electric motor provides power to the bike, allowing the rider to pedal with less effort and to reach higher speeds than a traditional bicycle.
The motor is typically located in the hub of one of the wheels or in the bottom bracket, and it is controlled by a handlebar-mounted thumb throttle or a pedal-assist sensor. The motor receives power from a battery, which is usually located on the bike frame and can be recharged using a standard electrical outlet.
When the rider pedals, the bike's sensors detect the pedal movement and send a signal to the electric motor to provide power. The amount of power the motor provides can be adjusted using the bike's controls, and the rider can choose to use only the electric motor, only the pedals, or a combination of both.
As you pedal, the electric motor work in combination with your pedaling to give a boost, thus assist you while riding. Also many e-bike have a PAS (Pedal Assistant System) which means that when you are pedaling the bike will automatically turn on the electric motor to assist.
In summary, an electric bike works by using an electric motor to assist the rider's pedaling, making it easier to ride and allowing the bike to reach higher speeds.
