Electric bicycles have two basic methods of control: using the pedal and the power control mechanism. As the name implies using electric bike helps you in pedaling and pedaling requires certain physical effort. Using this method, adjustment of the sensor (torque) measures the speed or torque load to determine the necessary power of the motor. Everything is automated and therefore does not need to think about anything just sit in the saddle and ride. Some electric bikes have a lot of settings, while others may have only one power adjustment. You can configure the necessary assistance to the pedaling. With weak settings help in pedaling is barely noticeable, but it will help to increase the operating time of the motor. In stronger power settings more visible, and you can achieve very high speeds, because at the same time pedaling you will be helping the engine to its full capacity.
On the other hand the power control mechanism does not require any rotation of the pedals. Just like on a motorbike in order to control the power and speed to rotate and hold the throttle. You may continue pedaling, but not necessarily.
Some electric bikes are controlled only by means of rotation of the pedals, the other equipped with a power control mechanism, and some has both mechanisms. Usually, bicycles with pedaling assistance have a lot of power settings from which you can select the appropriate conditions for the trip, and electric bicycles with both adjustment mechanisms have limited adjustment aid pedaling. These bikes provide a mechanism for full control of the power control (when appropriate), and assistance in pedaling is of secondary importance on a flat terrain.
Now most of the models are equipped with brushless electric bikes spigot motor, built directly into the front or rear wheel. But some cheaper systems like Ezip, using an external motor with chain drive. Although these units are cheaper and provide good torque, they are not so gentle, efficient and unobtrusive as bush motors are used in most electric bikes. In the sleeve engine, there are several sub-groups:
Geared motors bush.
Most electric bikes use a brushless ready gear bush motors. These motors have a planetary transmission, which helps to transmit power from the engine to the wheel. Thanks to the planetary gear motors provide excellent data of torque, but with their help it is impossible to achieve high speeds. These benefits include high torque, which means good power during acceleration and the ability to overcome steep climbs. In addition to rotate the motor requires less power, which means they have less size and weight. In the ready electric bicycles motor power ranges from 200 to 500 watts and can reach speeds up to 32 km / h. But you can also buy kits for electric bikes with increased maximum power up to 1000 watts and a huge torque, which is very important in the highlands. They have a lower top speed, they are expensive and subject to wear of the planetary transmission.
Gearless (direct wire) motors bush.
Some conversion kits and electric bicycles themselves used gearless motors with direct line. Their operation mechanism is based on an alternating current to the motor windings, which sets it in motion. Even if they consider the impact of corrosion, this type of engine will last a lot longer, because it does not have a planetary gear and moving components do not communicate directly with each other. They are able to develop a great top speed. But because of the absence of the planetary gear have less torque and thus to achieve maximum speed they require more power. This means that the size of the direct drive motors are heavier and larger gear motors. Most bush motors with direct line (for example, conversion kits for electric bikes E-Bike) have a capacity of 350 500 watts and reach a top speed of 29 40 km / h. More powerful engines (for example, Crystalyte) capable of reaching speeds of over 56 km / h.
Installation configuration of motor-wheel.
There are two different installation configurations motor-wheel in front or behind.
Installed in the front sleeve engines can be found on finished or refurbished bicycles. If you pereoboruduete standard bike, then the simplest solution is to install the engine in the front, as in this case, no problems with speed or chain. And since most of the conversion kits for electric bikes include a battery is installed on the rear trunk, using the sleeve of the motor bike in front counterbalances the weight and improves handling. Since there is a small risk of the destruction of the front fork motor, it is strongly recommended to use a sleeve motor on the front wheel only with a steel fork. For ready-made bike is not a problem, because usually kombinirueyutsya motors with steel forks and they are not as powerful.
Rear-mounted motor-wheel.
Sleeve motors mounted on the rear wheel, distributed mainly on finished bicycles as motor factory set back is easy. But to convert a bicycle with rear-wheel motor a little more complicated than in the case of the sleeve with front engine, because there are problems with chain, transmission and switch gear. Plus, you may be limited to the 6- or 7-speed ratchet. However, the motor on the rear wheel provides greater torque and less noticeable on the front wheel.
