Installed in the middle position of an electric bicycle (i.e. the bicycle pedal), it is transmitted to the rear wheel through a transmission device (such as a chain+flywheel), usually using a high-speed motor with a smaller diameter and an inner shaft rotor (similar to common motor forms)
The function of the central motor can be divided into two types:
The first type is a simple mid mounted drive motor. Bicycles equipped with this motor can have two riding modes, namely manual riding mode and fully automatic riding mode. Riders can switch and choose between these two riding modes according to their actual needs.
The second type is a mid mounted drive motor with real-time assistance. Bicycles equipped with this motor can have three riding modes: manual riding mode, assisted riding mode, and fully automatic riding mode. Riders can also switch and choose directly from these three riding modes according to their actual needs. The assisted riding mode, with its healthy and high endurance assisted riding characteristics, will surely become the future development trend.
Advantages:
A mid mounted motor is a product that combines mechanics and electronics. Structurally, it is not simply a motor, but a power output assembly that amplifies torque through a mechanical structure. With the same motor power, a mid mounted motor can output greater torque through the mechanical structure, achieving the characteristics of low power consumption and high output torque.
Summary of advantages:
Firstly, the price is low and the requirements for the controller are not high.
Secondly, the torque is high, and the rear flywheel can idle and slide far away, which is very energy-efficient.
Thirdly, the continuously variable transmission is equipped with gears, speeds, and torques according to the gear ratio.
