4 key parts of electric bike
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 critical 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 are 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. Brakes Some electric bikes claim to use a neat trick called regenerative braking. If you start pedaling the bicycle or going downhill, the spinning wheels turn the electric motor in the hub in reverse and start charging up the batteries. In practice, regenerative braking is nowhere near as useful on an electric bicycle as it is on an electric train or car. An electric bike has much less mass and velocity than either a train or car, so it never gains (or loses) anything like as much kinetic energy when it starts and stops. You'd have to go down an awful lot of hills to charge up the batteries completely and that's usually not practical. And what's the point in pedaling the wheels simply to charge the battery? You might as well have bought an ordinary bicycle to start with! Frame The frame of an electric bike also has to be slightly different. The main part of the frame (the bit that supports your weight) is usually made from lightweight aluminum alloy: the lighter the frame, the lighter the weight of the bike overall, and the further it can travel before you need to recharge the batteries. The spokes on the wheel also have to be stronger than the thin spokes on a traditional bicycle. That's because the electric motor in the hub spins the wheel with a lot of turning force (known as torque) and, if the spokes were ordinary lightweight ones, they could bend or buckle. And then you’re off, experiencing all the power-assisted joys of life on two wheels. And if you’re yet to join in the e-bike revolution, why not hand DKY RETRO start your next trip?
