The Electric bike is one of the most agile, leisurely vehicles of our time, which have updated through added batteries on the basis of the normal bicycle, so it can be more labor-saving to ride in complex areas. It is very friendly for the elderly and disabled people and helps them a lot. In the past few years, with the positive impact on health, environment and society, electric bicycles have injected new life into people's travel and began to change our concept of environmental protection completely. Now let's take a more detailed look at how it works. Electric bikes have all the components of an original bike, but with some crucial extras that add power for pedaling and allow you to travel further without getting as tired. There are four key parts of an electric bike: the batteries, the motor, the sturdy frame and spokes, and the brakes.
Batteries The batteries are the most central parts of the bike, because they incorporate all the power that will drive you along. Typical electric bike batteries make about 350–500 W of power. This can be located in the luggage rack or low down on the frame, offering a more natural weight distribution of the E-bike. The battery charges with five to six hours of most cases, is easy to replace, and many riders carry a spare for cycling longer distances.
The Electric motor In the theoretical electric bike we considered up above, we had the dynamo/motor driving the back wheel directly, simply by pressing on the tire. Most electric bikes work a different way. They have compact electric motors built into the hub of the back or front wheel (or mounted in the center of the bike and connected to the pedal sprocket). Take a look at the hub of an electric bike and probably you'll see it's much fatter and bulkier than on a normal bike.
