How to buy Gas Motorcycles, we believe that before buying, we must first understand the types and performances of Gas Motorcycles. Gas Motorcycles consists of five major components: body, battery, motor, controller and charger.
Due to the different design and selection of electrical components by various manufacturers, their appearance, function, structure, performance and manufacturing cost are different: firstly, the types of Underbone can be divided into two categories: all-electric and intelligent power-assisted. All are equipped with power source, power device and control system. The battery as the power source also comes with a matching charger. The electric drive does not require manpower, and the speed is controlled by the handle to realize stepless and arbitrary speed change from 0-20km/h. Equipped with a set of 36V12Ah batteries, the range of a single charge can reach 60 kilometers, which is the mainstream of current market products.
The second is the intelligent motor-assisted Gas Motorcycles: it can be called a real motor-assisted vehicle, with a special sensor, which responds through the control system after receiving an external force. The so-called electric drive, compared with pure electric drive, the battery mileage of the same capacity can be doubled. The intelligent mobility-assisted type is a true mobility-assisted vehicle because it relies mainly on manpower and supplemented by electric power, and will become the development direction of Gas Motorcycles.
Types of motors Underbone can be divided into three types: friction transmission, center shaft sprocket transmission and wheel hub drive according to the power device selected by it - the structure of the motor. The technical difficulty lies in the difficulty in heat dissipation of the motor and the difficulty in lubrication of the transmission gear. In-wheel motors are divided into brushless and brushed. Brushless motors are mainly low-speed high-torque motors without brushes and transmission gears to avoid mechanical wear and tear. However, the large starting current impact, low overload capacity, complex structure of the control system, and high failure rate have affected the wide application of the motor.
Hub-driven Gas Motorcycles, the Underbone motor is installed in the hub of the wheel, and the hub is connected with the rim by the spokes to directly drive the wheel to rotate. Reasonable design, compact structure, small size and light weight, compared with other transmission forms, it has low energy consumption and high efficiency. Motor types are divided into brushless motors and brushed motors. The friction transmission type three-wheel motorcycle is equipped with a battery box and a controller on an ordinary bicycle, and the wheel on the motor shaft is directly loaded on the tire of the car, and is driven by friction. The structure is simple and the cost is low, but the tire wears a lot, especially in the rainy season, it is easy to slip, the energy consumption is large, and the efficiency is low. Central shaft sprocket transmission type Underbone, the motor is specially designed on the central shaft of the frame, the central shaft is driven by the reduction mechanism, and the rear wheel is driven by the central shaft through the chain.
