We choose the electric motor for a bicycle
Currently, the industry produces various models of motorcycles that use electric traction for movement. However, such "green" funds are not affordable for everyone.
Today, many lovers of rapid movementtake care at the same time of the preservation of the environment. They are increasingly turning their attention to bicycles. A simple electric motor for a bicycle allows you to travel long distances, while using the muscular strength of your legs is not necessary.
Such models will be especially appreciated by those who live inmountainous terrain, where heavy rises in the hill discourage many from any desire to sit in a bicycle saddle. Also, such extra bike features will be appreciated by those people who are not in the best physical shape, for example, the older generation.
Electric motors for bicycles were developedmany inventors. However, to date, not only Kulibins have the opportunity to use electric bicycles. Many firms have established the production of such machines. Electric motors for a bicycle are available in several types.
Such an electric motor for a bicycle is distinguishedlow price. Here, in the same housing with the collector motor itself, a reducer is placed, which is designed to lower the revolutions. At the same time, the engine has a rather powerful torque, allowing it to reach speeds of up to 25 km / h. For many, this speed is sufficient for a quick move.
But this electric motor for a bicycle hascertain shortcomings. Among them, and a complex installation of the motor on the bicycle, as well as the wear of brushes. Such a motor is perfect as an inexpensive variant of conversion for absolutely any bicycle.
This type can be divided, in turn, into two subspecies: direct drive and gearboxes.
Direct Drive Motors
Electric motor for bicycle with direct drivegives the opportunity to develop a speed of 45 km / h. Among the advantages of such motors is a simple installation, a reliable design with a minimum of wearing parts. They also have high efficiency. But the disadvantages of such engines are the large size and weight of the motor. A good battery for such an engine weighs an average of 4.3 kg.
This type of engine is most often used onfactory models. Compared to geared motors, motors with planetary gears that are integrated into the rear or front wheel hub are distinguished by a number of advantages. Such engines have smaller dimensions, greater traction (torque), and economical energy consumption. Among the shortcomings, it should be noted a lower efficiency than brushless motors, a rather complex design. If the maximum speed of 25 km / h for a bicyclist is sufficient, we can safely recommend this type of electric motor for a bicycle.
