In the third quarter of this year, Xiamen Industrial and Commercial Bureau conducted a sample inspection of the auto parts sold in the market. The test results show that all samples meet the requirements of national standards. The central motor we are referring to here is a central Ebike Motor used on lithium-ion assisted Electric Bicycles, while the common one is the motor used on lithium-ion mountain assisted bicycles. It was developed and put into use after the hub motor, and compared to the hub motor, the technology of the central motor is not yet very mature, so there is still a long way to go in terms of performance stability. But the central motor has a characteristic that hub motors do not have, which is its instantaneous starting assistance function, so it also has a corresponding market. The most common method is to install a center mounted motor on a mountain Electric Bike to meet the bumpy road conditions in the mountains, so both hub motors and center mounted motors have their advantages and disadvantages. The choice of motor depends entirely on which aspect of its functionality you value.Generally speaking, the central motor is used to assist mountain bikes, and hub motors are more common on urban series of assist bicycles.
