What is an ebike?
With the developing of ebike, most people will ask what is an ebike?An ebike also known as an electric bike is a bike with an intergrated electric motor which can be used for propulsion. From the late19 century to now, many kind of ebikes are created available worldwide. From an e-bike that only have a small motor to assist the rider’s pedal-power (i.e. pedelecs) to more powerful e-bikes which are closer to moped-style functionality. The biggest difference with motorcycle is ebike retain the ability to be pedalled by the rider.
Compared with normal bike, electric motor, battery, controller and LCD display are the important part of an ebike. Generally, an ebike use rechargeable lithium batteries and the lighter ones not only can reduce an ebike weight, also can travel up 40 to 60 km based on the flat road with no wind. 36V and 48V are very commom battery volt for each ebike, depending on your requirements, can choose 8Ah, 10Ah and 13Ah even 20Ah battery to your ebike. In some markets, they are gaining in popularity and taking some market share away from conventional bicycles, as the same time, they are also replacing fossil fuel-powered mopeds and small motorcycles. Becoming people travel transptation vehicle slowly.
The two most common types of hub motors used in an ebike are brushed and brushless. The motor is built into the wheel hub itself, so an electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. Hub motors also is very commom types on the ebike, about 80% ebikes use it. Another types of electric assist motor is mid-drive motor. Different with hub motor, this electric motor is not built into the wheel but is usually mounted near (often under) the bottom bracket shell. Thus the propulsion is provided at the pedals rather than at the wheel, being eventually applied to the wheel via the bike’s drive train. Because the power is applied through the chain and sprocket, the motor power is limited to around 250–500 watts can better to protect against fast wear on the drivetrain. However, the power of motor is often influenced and limited by local legal.
According to brushed motor or brushless motor, There are two distinct types of controllers designed to match them. Now as the cost of controllers continues to decrease, most ebike brands are starting to use brushless motors. For example Shuangye electric bike. Compared with controllers for brushed motor, controller for brushless motors need to provide assistance as a function of the Hall sensor commutation inputs, the vehicle speed and the required force. At many aspects, the performance of brushless motor is better than brushed motor.
Display can show an ebike real-time riding infornmation. There are LED display and LCD display using o nthe ebike, if LCD display can know more realtime information, not only battery capacity and pedal assist level, but also know trip distance, motor power, riding speed and so on, even you can know the malfunction of an ebike through the error sign on the LCD display.
Actually, an ebike is the electric motor-powered versions of normal bike. Because ebikes are legally classified as bicycles at many place local laws, this make them not like electric motorcycles from the more stringent laws regarding the certification and operation.
