Electric bicycles, or e-bikes, use an electric motor and a rechargeable battery to help the rider pedal the bike. They can be pedaled like a regular bicycle, or the rider can use the electric motor to assist pedaling, making it easier to ride longer distances or uphill.

E-bikes come in a variety of styles, including road, mountain and hybrid, but the basic mechanics are the same. When the rider pedals the bike, the motor provides additional power, controlled by a handlebar-mounted throttle or a sensor that detects the rider's pedaling effort.

Motor assistance can be adjusted, usually via a control panel on the handlebars, to suit the rider's needs. Some e-bikes have multiple levels of assistance, allowing the rider to choose how much help they need from the motor. The rider can also choose not to use any assistance and pedal the bike like a normal bike.

The battery used in an e-bike can be charged using a regular wall outlet and typically takes a few hours to be fully charged. The range of an e-bike depends on several factors, including the size of the battery, the efficiency of the motor and the weight of the rider, but most e-bikes can travel around 30-50 km on a single charge.

In addition to the motor and battery, e-bikes also typically have a variety of other components, including a display that shows the rider the battery charge and other information, lights for better visibility, and a stand for parking the bike. Some e-bikes also have other features, such as built-in locks, weather protection and integrated storage solutions.

Overall, e-bikes are a great option for people who want to get around by bike but find regular bikes too challenging due to hills, headwinds, or distance. They also provide a convenient way to run errands, commute to work, or take leisure trips without the need for a car.
